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] Show me all BOMs which have at least on part from a polish supplier.

[Assistant]
To answer this question, I need to identify the following:
1. The entity or class representing BOMs (Bill of Materials).
2. The property that links BOMs to their parts.
3. The property that links parts to their suppliers.
4. The property or way to identify that a supplier is from Poland.

Step 1: Search for the entity representing BOMs.

[Tool]
Top 10 entity alternatives:
1. BOM Part (pv:BomPart): A (number of) part(s) in a BOM.
2. bom 4 (prodi:bom-4): is a Bill of Material (BOM)
3. bom 19 (prodi:bom-19): is a Bill of Material (BOM)
4. bom 12 (prodi:bom-12): is a Bill of Material (BOM)
5. bom 2 (prodi:bom-2): is a Bill of Material (BOM)
6. bom 11 (prodi:bom-11): is a Bill of Material (BOM)
7. bom 18 (prodi:bom-18): is a Bill of Material (BOM)
8. bom 6 (prodi:bom-6): is a Bill of Material (BOM)
9. bom 15 (prodi:bom-15): is a Bill of Material (BOM)
10. bom 5 (prodi:bom-5): is a Bill of Material (BOM)

[Assistant] There are multiple entities representing BOMs, for example, prodi:bom-4, prodi:bom-19, prodi:bom-12, etc. I will check the properties of one of these BOM entities to understand how parts are linked to BOMs. I will start with prodi:bom-4.

[Assistant]
The supplier entity has properties indicating the country, such as pv:addressCountry, pv:addressCountryCode, and pv:country. The country is represented as a literal or as a dbpedia resource. I will use pv:addressCountry or pv:country to filter suppliers from Poland.

Now I will construct a SPARQL query to find all BOMs that have at least one part from a Polish supplier. I will use the property pv:hasBomPart to link BOMs to BOM parts, pv:hasPart to link BOM parts to parts, and pv:hasSupplier to link parts to suppliers. Then I will filter suppliers with pv:addressCountry or pv:country containing "Poland".

For each Employee, I retrieved their name, email, phone number, the department they belong to, and their direct reports (employees who have them as their manager). The results include the employee's identifier, their name, email, phone number, department identifier and name, as well as the identifiers and names of their direct reports if any.

I want to update my contact list, for each Employee give me name, email, phone number and the department they belong to as well as their direct report.

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] I want to update my contact list, for each Employee give me name, email, phone number and the department they belong to as well as their direct report.

[Assistant]
To answer your question, I need to identify the entities and properties related to Employees, their names, emails, phone numbers, departments, and direct reports in the knowledge graph.

Step 1: Search for an example Employee entity to understand how Employees are represented.
Step 2: Search for properties related to Employee that might include name, email, phone number, department, and direct report.
Step 3: Construct a SPARQL query to retrieve the requested information.

I will start by searching for an entity related to "Employee" in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. Employee (pv:Employee): An employee in my company., is subclass of Agent
2. employee line svg?color=#D6AF00&format=svg (<https://api.iconify.design/clarity/employee-line.svg?color=%23D6AF00&format=svg>)

[Assistant] I found an entity "Employee" (pv:Employee) which represents an employee in the company. Next, I will search for properties related to this Employee entity that might include name, email, phone number, department, and direct report.

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

No other items found

[Assistant] The Employee entity does not have a direct property called "name," but it likely uses rdfs:label for the name. I will now search for properties related to email for the Employee entity.

[Tool]
Top 10 property alternatives:
1. comment (rdfs:comment)
2. label (rdfs:label)
3. type (rdf:type)

No other items found

[Assistant] No direct property for email was found for the Employee entity. I will try a more general property search for "email" in the knowledge graph to see if there is a common property used for email addresses.

[Tool]
Top 10 property alternatives:
1. email (pv:email): The e-mail of an agent., has domain Agent
2. address text (pv:addressText): The address text., has domain Agent
3. address country (pv:addressCountry): The address country., has domain Agent
4. comment (rdfs:comment)
5. phone number (pv:phone): has domain Agent, A phone number.
6. name (foaf:name):

7. name (pv:name): The name of something.
8. license (<http://creativecommons.org/ns#license>)
9. label (rdfs:label)
10. ID (pv:id): The ID of a thing.

[Assistant]
I found relevant properties: pv:email for email, pv:phone for phone number, and pv:name or foaf:name for name. These properties have domain Agent, and Employee is likely a subclass of Agent.

Next, I will search for properties related to department and direct report for the Employee entity. I will start with "department."

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

No other items found

[Assistant] No direct property for department was found for the Employee entity. I will try a more general property search for "department" in the knowledge graph.

[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
6. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
7. sub Class Of (rdfs:subClassOf)
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 relevant property "pv:memberOf" which indicates the department to which an agent belongs. This property has domain Agent and range Department.

Next, I will search for properties related to "direct report" or similar hierarchical relationships for Employee. I will try "manager" first as it might indicate a direct report relationship.

[Tool]
Top 10 property alternatives:
1. label (rdfs:label)
2. type (rdf:type)
3. sub Class Of (rdfs:subClassOf)
4. is Defined By (rdfs:isDefinedBy)

No other items found

[Assistant] No direct property for manager was found for the Employee entity. I will try a more general property search for "manager" in the knowledge graph.

[Tool]
Top 10 property alternatives:
1. has manager (pv:hasManager): The manager of the employee., has domain Employee, has range Manager
2. has product manager (pv:hasProductManager): The employee acting as the product manager of the product., has range Employee, has domain Product
3. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
4. contributor (dct:contributor)
5. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
6. publisher (dct:publisher)
7. name (foaf:name):

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]
I found a relevant property "pv:hasManager" which indicates the manager of the employee. This property has domain Employee and range Manager.

To find the direct reports of an employee, I can look for employees who have this employee as their manager.

Now I have identified the following properties for the query:
- Name: pv:name or foaf:name or rdfs:label
- Email: pv:email
- Phone number: pv:phone
- Department: pv:memberOf
- Direct report: employees who have the current employee as their pv:hasManager

I will construct a SPARQL query to retrieve for each Employee their name, email, phone number, department, and direct reports.

There are no BOMs with parts sourced from Russia in the current data, so there is no service that applies to such a BOM.

Do we have any service that does apply to a BOM where parts are sourced from Russia?

[User] Do we have any service that does apply to a BOM where parts are sourced from Russia?

[Assistant]
To answer this question, I need to clarify a few points:
- "service that does apply to a BOM" likely means a service related to a Bill of Materials (BOM).
- "parts are sourced from Russia" means parts in the BOM have a sourcing location or origin in Russia.

Step 1: Identify entities related to "service" and "BOM" in the knowledge graph.
Step 2: Identify properties related to sourcing or origin of parts, especially related to Russia.
Step 3: Check if there is any service linked to a BOM where parts are sourced from Russia.

I will start by searching for entities related to "BOM" and "service" in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. BOM Part (pv:BomPart): A (number of) part(s) in a BOM.
2. bom 4 (prodi:bom-4): is a Bill of Material (BOM)
3. bom 19 (prodi:bom-19): is a Bill of Material (BOM)
4. bom 12 (prodi:bom-12): is a Bill of Material (BOM)
5. bom 2 (prodi:bom-2): is a Bill of Material (BOM)
6. bom 11 (prodi:bom-11): is a Bill of Material (BOM)
7. bom 18 (prodi:bom-18): is a Bill of Material (BOM)
8. bom 6 (prodi:bom-6): is a Bill of Material (BOM)
9. bom 15 (prodi:bom-15): is a Bill of Material (BOM)
10. bom 5 (prodi:bom-5): is a Bill of Material (BOM)

[Assistant] There are multiple entities representing Bill of Material (BOM) such as prodi:bom-4, prodi:bom-19, prodi:bom-12, etc. I will now search for entities related to "service" to understand how services are represented in the knowledge graph.

[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) represents some value-added service realized based on other products. This seems relevant to the question.

Next, I will check the properties of the "Service" entity to see if there is any property linking it to a BOM or parts.

[Assistant]
There are no direct instances of Service listed here, only the class definition.

I will now try to find any BOM that has parts sourced from Russia by checking the chain: BOM -> BOM Part -> Product -> Supplier -> Country (Russia).

I will write a SPARQL query to find BOMs with parts sourced from Russia.

[Tool] Got no rows and 1 columns

[Assistant]
No BOMs found with parts sourced from Russia in the current data.

I will now check if there are any products sourced from Russia at all, to verify if the data contains such sourcing information.

[Tool] Got no rows and 1 columns

[Assistant]
No products found with suppliers located in Russia in the current data.

Since there are no parts or products sourced from Russia, there cannot be any service applying to a BOM with parts sourced from Russia.

I will now provide the final answer.

Which supplier delivers the most reliable Inductor?

[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 delivers the most reliable Inductor?

[Assistant]
To answer the question "Which supplier delivers the most reliable Inductor?" I need to break down the question into parts:

1. Identify entities: "supplier," "Inductor."
2. Identify the property related to reliability of the Inductor delivered by suppliers.
3. Find suppliers who deliver Inductors.
4. Determine the reliability of the Inductors delivered by each supplier.
5. Find the supplier with the highest reliability.

Step 1: Search for the entity "Inductor" in the knowledge graph to find its identifier.

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

[Assistant]
The entity "Inductor" is identified as a product category with the identifier prodi:prod-cat-Inductor.

Step 2: Search for suppliers who deliver products in the category "Inductor." I will look for properties related to delivery or supply from suppliers to products or product categories.

[Assistant]
The property "pv:hasSupplier" seems relevant as it indicates the supplier of a product. I will now check if products in the category "Inductor" have suppliers linked via this property.

Step 3: Check if there are products in the category "Inductor" and their suppliers using the property pv:hasSupplier.

[Tool] Got no rows and 2 columns

[Assistant]
No products of the category "Inductor" were found with suppliers using the property pv:hasSupplier. I will try to find other properties related to suppliers or delivery for products in general.

Step 4: Search for properties related to suppliers for the entity "Inductor" or products in general.

[User] What is the heaviest coil that does not exceed a base area of 15x15 milimeter?

[Assistant]
To answer this question, I need to find coils with a base area not exceeding 15x15 millimeters and then determine the heaviest among them.

Step 1: Identify the property or properties that represent the base area or dimensions of the coil. I will search for properties related to "base area" or "dimensions" for coils.

Step 2: Identify the property that represents the weight of the coil.

Step 3: Query coils with base area not exceeding 15x15 mm and find the heaviest one.

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

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.
