[User] What is the most expensive service we offer?

[Assistant]
To answer the question "What is the most expensive service we offer?" I need to identify the entities representing services and their associated prices or costs in the knowledge graph. Then I will find the service with the highest price.

Step 1: Search for entities related to "service" in the knowledge graph to understand how services are represented.
Step 2: Search for properties related to "price" or "cost" to find how the price of a service is represented.
Step 3: Query the knowledge graph to find the service with the highest price.

I will start with step 1 and search for entities related to "service."

[Tool]
Top 10 entity alternatives:
1. Service (pv:Service): Some value added service realized based on other product(s)., is subclass of Product
2. account service outline svg?color=#D6AF00&format=svg (<https://api.iconify.design/mdi/account-service-outline.svg?color=%23D6AF00&format=svg>)

[Assistant]
The entity "Service" (pv:Service) is identified as a value-added service realized based on other products and is a subclass of Product. This seems to be the correct entity representing services.

Next, I will search for properties related to "price" or "cost" to find how the price of a service is represented in the knowledge graph.

[Tool]
Top 10 property alternatives:
1. price (pv:price): The price specification of a product., has domain Product, has range Price
2. currency (pv:currency): has domain Price, The currency.
3. amount (pv:amount): has domain Price, The amount.
4. name (foaf:name):

5. name (pv:name): The name of something.
6. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
7. quantity (pv:quantity): The quantity needed., has domain BOM Part
8. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
9. ID (pv:id): The ID of a thing.
10. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product

[Assistant]
The property "price" (pv:price) is used to specify the price of a product and has the domain Product. Since Service is a subclass of Product, this property should be applicable to services as well.

Now I will write a SPARQL query to find the service with the highest price. I will select services and their prices, order by price descending, and limit the result to 1. I will also try to get the label of the service for better readability.

The knowledge graph contains information about employees and their managers using the property 'has manager'. However, there is no clear or direct information linking employees or managers to departments. The property 'member of' which seemed relevant does not have values for the checked employees or managers. Also, no other properties related to departments were found for employees or managers. Therefore, it is not possible to calculate the percentage of team members working in the same department as their manager with the available data.

For each manager, what percentage of their entire team work in the same department as the manager?

[User] For each manager, what percentage of their entire team work in the same department as the manager?

[Assistant]
To answer this question, I need to identify the following information from the knowledge graph:
1. Managers and their teams (employees they manage).
2. The department of each manager.
3. The department of each team member.
4. Calculate the percentage of team members who work in the same department as their manager.

Step 1: Identify how managers and their teams are represented in the knowledge graph. I will start by searching for entities related to "manager" to understand how managers are represented.

[Assistant]
I found an entity "Manager" (pv:Manager) which is a subclass of Employee. Also, there is a property "has manager" (pv:hasManager) which relates an employee to their manager. This suggests that employees have a property linking them to their manager.

Next, I will check how teams are represented. Since employees have a "has manager" property, I can find all employees who have a specific manager to identify the team of that manager.

Now, I need to find how departments are represented and linked to employees and managers. I will search for properties related to "department" to see how departments are linked to employees or managers.

[Assistant]
I found a property "member of" (pv:memberOf) which links an agent (likely including employees) to a department. This property seems suitable to find the department of both managers and employees.

Next, I will verify that managers are also linked to departments using the "member of" property. I will check for some instances of managers and their departments. For that, I will first list some instances of the class Manager.

[Assistant] The class Manager is a subclass of Employee, but I did not get instances of managers yet. I will try to find instances of employees who are managers by checking employees who have direct reports. I will look for employees who are objects of the property "has manager" to find managers.

[Assistant]
I found employees with their managers using the property "has manager" (pv:hasManager). The object of this property is the manager. Now, I want to find the departments of these managers and employees. I will check the departments of some employees using the "member of" property. I will check the departments of the managers as well.

I will start by checking the department of a specific manager, for example, "empl Elena Herzog@company org".

[Tool] Constraint "empl:Elena.Herzog@company.org" for subject position is not a valid IRI. IRIs can be given in prefixed form, like "wd:Q937", as URIs, like "http://www.wikidata.org/entity/Q937", or in full form, like "<http://www.wikidata.org/entity/Q937>".

[Assistant] The identifier "empl Elena Herzog@company org" contains spaces and special characters, so it needs to be enclosed in angle brackets to be used as a valid IRI in the query. I will retry the query with the correct IRI format.

[Tool] Got no rows and 3 columns

[Assistant] The manager "Elena Herzog" does not have a direct "member of" property linking to a department in the data I checked. I will check if the employees have the "member of" property linking to departments. I will check the department of an employee, for example, "empl Wolfgang Martin@company org" who has Elena Herzog as manager.

[Tool] Got no rows and 3 columns

[Assistant] Neither the manager nor the employee has a direct "member of" property linking to a department. I will try to find if there is another property linking employees or managers to departments. I will search for properties related to "department" again but with a broader search to find any other relevant properties.

[Tool]
Top 10 property alternatives:
1. label (rdfs:label)

9. depth (mm) (pv:depth_mm): The depth of an item measured in millimeter., has domain Hardware
10. sub Class Of (rdfs:subClassOf)

[Assistant]
I did not find any other property explicitly linking employees or managers to departments. The property "member of" seemed the most relevant but did not yield results for the checked individuals.

I will now check if the department information might be linked indirectly, for example, through another entity like "Agent" or "Employee" having a department property. I will check the properties of an employee to see if there is any property related to department. I will check properties of the employee "empl Wolfgang Martin@company org".

[Tool]
No property items found

No other items found

[Assistant] There are no properties related to "department" for the employee entity I checked. I will try a broader search for properties of the employee without any filter to see what properties are linked to employees. I will check properties of the employee "empl Wolfgang Martin@company org" again but without a query filter.

[Tool]
No property items found

No other items found

[Assistant]
There are no properties found for the employee "empl Wolfgang Martin@company org". This might indicate that the employee instances do not have direct properties linking them to departments or other entities in the current data.

Given this, it seems the knowledge graph does not have the necessary information or structure to answer the question about the percentage of team members working in the same department as their manager.

I will now provide a detailed explanation and cancel the query generation.

You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

qb: <http://purl.org/linked-data/cube#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Who is the manager of the Data Services department?

[Assistant]
To answer the question "Who is the manager of the Data Services department?", I need to identify the entity representing the "Data Services" department and the property that relates a department to its manager. Then I will query for the manager of the "Data Services" department.

Step 1: Search for the entity "Data Services" in the knowledge graph.

1. Dataset (void:Dataset)
2. Datatype Property (owl:DatatypeProperty)

[Assistant] The search for "Data Services" did not return a direct match for a department entity. I will try a broader search for "department" to see if there is a relevant entity or class that might include "Data Services" as an instance or label.

4. ID (pv:id): The ID of a thing.
5. type (rdf:type)

8. name (pv:name): The name of something.
9. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
10. creator (dct:creator)

[Assistant]
The property "has manager" (pv:hasManager) is defined with domain Employee and range Manager, which might not be directly applicable to Department. The property "has product manager" is related to Product, not Department. The property "responsible for" relates Department to Product, not to a manager.

I will now check if the Department entity has any property that links it to an Employee or Manager by listing properties of the Department instance prodi:dept-41622.

[Assistant]
The department "Data Services" has properties like label, name, ID, and responsible for (products or services), but no direct property indicating a manager.

I will now check if there is a property linking an Employee or Manager to a Department, such as "member of" or "manages". I will search for properties related to "department" for entities that might represent employees or managers.

[Tool]
Top 10 property alternatives:
1. area of expertise (pv:areaOfExpertise): The product category agent is expert for., has range Product Category, has domain Agent
2. label (rdfs:label)

[Assistant]
The property "member of" (pv:memberOf) has domain Agent and range Department. This might indicate which department an agent (employee) belongs to. Also, "has manager" (pv:hasManager) has domain Employee and range Manager.

I will now try to find employees or agents who belong to the "Data Services" department (prodi:dept-41622) and then check if any of them have a manager.

[Assistant] The employee "Elena Herzog" (prodi:empl-Elena.Herzog@company.org) appears as the manager for most employees in the "Data Services" department. I will now confirm if "Elena Herzog" is indeed the manager of the "Data Services" department by checking if she has a role or title indicating management. I will query for labels or titles of Elena Herzog.

[Tool]
Failed to call function execute:
failed to parse input: no matching token found from position 54: 'org rdfs:label ?label }'

[Assistant] The identifier for Elena Herzog contains special characters that need to be enclosed in angle brackets for the SPARQL query. I will correct the query and try again.

[Tool] Got no rows and 1 columns

[Assistant] There is no label for Elena Herzog. I will now check if there is any property indicating a role or title for this employee. I will list all properties of Elena Herzog.

[Tool] Got no rows and 3 columns

[Assistant]
There are no properties for Elena Herzog in the knowledge graph. However, based on the data, Elena Herzog is the manager of most employees in the Data Services department, which strongly suggests she is the manager of the Data Services department.

I will now provide the final answer.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Which supplier in France delivers Compensators?

[Assistant]
To answer the question "Which supplier in France delivers Compensators?", I need to identify the following entities and properties in the knowledge graph:
1. The entity or class representing "Supplier."
2. The entity or class representing "Compensators."
3. The property that links suppliers to the products they deliver.
4. The property that indicates the location or country of the supplier, specifically France.

Step 1: Search for the entity "Supplier" in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. Supplier (pv:Supplier): The Supplier of some item(s).
2. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier

[Assistant] The entity representing "Supplier" is pv:Supplier. Next, I will search for the entity "Compensators" in the knowledge graph.

[Tool] No entity items found

[Assistant] There is no direct entity named "Compensators" in the knowledge graph. I will try searching for the term "Compensator" in singular form to see if it exists.

[Tool]
Top 10 entity alternatives:
1. prod cat Compensator (prodi:prod-cat-Compensator): is a Product Category

[Assistant] There is an entity for the product category "Compensator" identified as prodi:prod-cat-Compensator. Next, I will search for properties that link suppliers to the products they deliver.

[Tool]
Top 10 property alternatives:
1. address text (pv:addressText): The address text., has domain Agent
2. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
3. comment (rdfs:comment)
4. quantity (pv:quantity): The quantity needed., has domain BOM Part
5. email (pv:email): The e-mail of an agent., has domain Agent
6. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
7. created (dct:created)
8. license (<http://creativecommons.org/ns#license>)
9. type (rdf:type)
10. phone number (pv:phone): has domain Agent, A phone number.

[Assistant] The property pv:hasSupplier links a product to its supplier. This means the product has a supplier, so the direction is from product to supplier. I need to find suppliers in France, so I will check properties related to location or country for suppliers. I will search for properties related to "country" or "location" for the entity pv:Supplier.

[Tool]
Top 10 property alternatives:
1. type (rdf:type)
2. label (rdfs:label)
3. is Defined By (rdfs:isDefinedBy)
4. depiction (foaf:depiction)
5. comment (rdfs:comment)

No other items found

[Assistant] No direct property related to "country" or "location" was found for the entity pv:Supplier. I will try searching for properties related to "address" or "location" for the entity pv:Supplier.

[Tool]
Top 10 property alternatives:
1. label (rdfs:label)

No other items found

[Assistant] There are no direct properties related to address or location for the entity pv:Supplier. I will try to find suppliers located in France by checking if the supplier entity has any related properties that might indicate location or country indirectly. I will list some triples with the subject pv:Supplier to explore possible properties.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

You can use the following SPARQL prefixes implicitly in all functions:

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] What is the name of the Network expert from the Marketing Department?

[Assistant]
To answer the question "What is the name of the Network expert from the Marketing Department?", I need to identify the following:

1. The entity representing the "Marketing Department".
2. The property or relation that links a person to their department.
3. The property or relation that indicates the expertise or role of a person, specifically "Network expert".
4. The property that provides the name of the person.

I will start by searching for entities related to "Marketing Department" in the knowledge graph.

2. emoji department store svg?color=#D6AF00&format=svg (<https://api.iconify.design/arcticons/emoji-department-store.svg?color=%23D6AF00&format=svg>)

[Assistant] I did not find a specific entity named "Marketing Department" but I found a general entity for "Department". I will now search for properties related to departments to see how departments and persons might be linked.

[Tool]
Top 10 property alternatives:
1. area of expertise (pv:areaOfExpertise): The product category agent is expert for., has range Product Category, has domain Agent
2. label (rdfs:label)
3. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
4. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
5. has manager (pv:hasManager): The manager of the employee., has domain Employee, has range Manager

8. quantity (pv:quantity): The quantity needed., has domain BOM Part
9. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
10. type (rdf:type)

[Assistant]
I found a property "member of" (pv:memberOf) which links an agent (person) to a department. This is likely how a person is linked to the Marketing Department.

Next, I will search for properties related to expertise or roles to find how "Network expert" might be represented.

10. created (dct:created)

[Assistant]
I found a property "area of expertise" (pv:areaOfExpertise) which seems to indicate the expertise of an agent (person). This is likely how the expertise "Network expert" is represented.

I also found properties "name" (foaf:name and pv:name) which can be used to get the name of a person.

Next, I will search for entities related to "Network" or "Network expert" to see how this expertise is represented.

Top 10 entity alternatives:
1. prod cat Network (prodi:prod-cat-Network): is a Product Category

[Assistant]
I found an entity "prod cat Network" (prodi:prod-cat-Network) which is a Product Category. This might be the value used for the "area of expertise" property for a Network expert.

Now, I will search for entities related to "Marketing" to find the specific Marketing Department entity.

[Tool] No entity items found

[Assistant] I could not find a specific entity for "Marketing Department" or "Marketing". I will try to find instances of departments to see if there is a Marketing Department instance.

[Assistant] I found several employees who are members of different departments identified by codes like dept 41622, dept 73191, etc. I will now check the labels or names of these departments to find which one corresponds to the Marketing Department. I will start by checking the label of dept 41622.

[Assistant]
I found two employees who are members of the Marketing Department and have the expertise "Network": empl Kevin Feigenbaum and empl Lambert Faust. However, their names are not provided with the foaf:name property.

I will now try to get their names using the pv:name property instead.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Which suppliers do we have in Toulouse?

[Assistant]
To answer the question "Which suppliers do we have in Toulouse?", I need to identify the entities related to suppliers and the location Toulouse in the knowledge graph. Then, I will look for properties that link suppliers to their locations.

Step 1: Search for the entity "Toulouse" in the knowledge graph to get its identifier.
Step 2: Search for entities related to "supplier" to understand how suppliers are represented.
Step 3: Identify properties that link suppliers to locations.
Step 4: Construct a SPARQL query to find suppliers located in Toulouse.

I will start with Step 1 and search for the entity "Toulouse".

[Tool] No entity items found

[Assistant] I could not find an entity for "Toulouse" in the knowledge graph. I will try to search for entities related to locations or cities to see if Toulouse might be represented differently or if there is a related entity.

[Tool] No entity items found

[Assistant] It seems there are no entities related to cities or Toulouse in the knowledge graph. I will now search for entities related to "supplier" to see if suppliers are represented and if there is any location information linked to them.

[Tool]
Top 10 entity alternatives:
1. Supplier (pv:Supplier): The Supplier of some item(s).
2. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier

[Assistant]
There is an entity "Supplier" with the identifier pv:Supplier and a property pv:hasSupplier that links products to suppliers. Now I need to find if there is any property that links suppliers to locations or addresses.

I will search for properties related to "location" or "address" for the entity pv:Supplier.

[Tool]
Top 10 property alternatives:
1. type (rdf:type)
2. label (rdfs:label)
3. comment (rdfs:comment)
4. depiction (foaf:depiction)
5. is Defined By (rdfs:isDefinedBy)

No other items found

[Assistant] There are no properties directly related to location for the entity pv:Supplier. I will try searching for properties related to "address" for the entity pv:Supplier.

[Tool]
Top 10 property alternatives:
1. label (rdfs:label)
2. comment (rdfs:comment)
3. type (rdf:type)
4. depiction (foaf:depiction)
5. is Defined By (rdfs:isDefinedBy)

No other items found

[Assistant] There are no properties related to address for the entity pv:Supplier either. I will try a broader search for properties related to "location" in the knowledge graph to see if there is any property that might link suppliers to locations.

[Tool]
Top 10 property alternatives:
1. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
2. price (pv:price): The price specification of a product., has domain Product, has range Price
3. name (foaf:name):

4. name (pv:name): The name of something.
5. lat (wgs84:lat)
6. phone number (pv:phone): has domain Agent, A phone number.
7. address text (pv:addressText): The address text., has domain Agent
8. address locality (pv:addressLocality): The address locality (city)., has domain Agent
9. range (rdfs:range)
10. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent

[Assistant]
I found some properties related to location and address:
- pv:country (domain Supplier)
- pv:addressText (domain Agent)
- pv:addressLocality (city) (domain Agent)

Since suppliers are a type of Agent, I can use pv:addressLocality to find the city of the supplier. Now I will search for the entity "Toulouse" as a literal value for the property pv:addressLocality to confirm its usage.

[Tool]
Failed to call function search_object_of_property:
too many values to unpack (expected 3)

[Assistant] There was an error while searching for the object "Toulouse" for the property pv:addressLocality. Instead, I will try to list some values of the property pv:addressLocality to see if Toulouse is among them.
