[User] Which hardware items - list id and name - have no active product manager?

[Assistant] To answer this question, I need to identify hardware items and check if they have an active product manager or not. I will start by searching for the concept of "hardware" to identify the relevant entity or class in the knowledge graph. Then, I will look for properties related to product managers and their status (active or not). Finally, I will construct a query to list hardware items that do not have an active product manager, including their ID and name.

[Tool]
Top 10 entity alternatives:
1. Hardware (pv:Hardware): The hardware products produced., is subclass of Product
2. hardware chip outline svg?color=#D6AF00&format=svg (<https://api.iconify.design/ion/hardware-chip-outline.svg?color=%23D6AF00&format=svg>)

[Assistant]
The entity "Hardware" with the IRI prefix pv:Hardware represents hardware products and is a subclass of Product. This is likely the class we want to focus on for hardware items.

Next, I will search for properties related to "product manager" to identify how product managers are linked to hardware items and if there is a property indicating their active status.

[Tool]
Top 10 property alternatives:
1. has product manager (pv:hasProductManager): The employee acting as the product manager of the product., has range Employee, has domain Product
2. has manager (pv:hasManager): The manager of the employee., has domain Employee, has range Manager
3. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
4. compatible product (pv:compatibleProduct): A compatible product., has domain Product, has range Product
5. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
6. contributor (dct:contributor)
7. creator (dct:creator)
8. depth (mm) (pv:depth_mm): The depth of an item measured in millimeter., has domain Hardware
9. publisher (dct:publisher)
10. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product

[Assistant]
The property "has product manager" (pv:hasProductManager) links a product to an employee acting as the product manager. This property has the domain Product and range Employee.

Now, I need to check how to determine if a product manager is active or not. I will search for properties related to the status or activity of an employee or product manager.

[Tool]
Top 10 property alternatives:
1. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
2. eligible for (pv:eligibleFor): Valid product service combinations (bundles, accessories)., has domain Service, has range Product
3. name (foaf:name):

4. name (pv:name): The name of something.
5. created (dct:created)
6. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
7. lat (wgs84:lat)
8. range (rdfs:range)
9. type (rdf:type)
10. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product

[Assistant] There is no direct property related to "active" status found in the top results. I will try searching for properties related to "status" to see if there is any indication of the activity status of a product manager or employee.

[Tool]
Top 10 property alternatives:
1. ID (pv:id): The ID of a thing.
2. label (rdfs:label)
3. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
4. comment (rdfs:comment)
5. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
6. version Info (owl:versionInfo)
7. created (dct:created)
8. eligible for (pv:eligibleFor): Valid product service combinations (bundles, accessories)., has domain Service, has range Product
9. name (foaf:name):

10. name (pv:name): The name of something.

[Assistant] There is no direct property related to "status" or "active" for employees or product managers found in the top results. I will now check the properties of the "Employee" class to see if there is any property indicating the active status of an employee. I will first search for the entity "Employee" to confirm its IRI.

[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] The entity "Employee" with the IRI prefix pv:Employee represents an employee in the company. I will now search for properties of the entity pv:Employee to find any property related to the active status of an employee.

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

No other items found

[Assistant]
There is no direct property related to the active status of an employee in the knowledge graph. Given this, I will assume that the presence of a product manager linked to a hardware item indicates an active product manager. Therefore, hardware items without any linked product manager can be considered as having no active product manager.

I will now construct a SPARQL query to list hardware items (ID and name) that do not have a product manager.

[User] What is the telephone of Baldwin Dirksen?

[Assistant]
Step 1: Identify the entity "Baldwin Dirksen" in the knowledge graph to get its IRI.

I will search for the entity "Baldwin Dirksen" in the knowledge graph ck25.

[User] Do we have suppliers in Toulouse?

[Assistant]
To answer the question "Do we have suppliers in Toulouse?" I need to check if there are any entities classified as suppliers that have a location or address linked to Toulouse.

Step 1: Identify the entity or class for "supplier" in the knowledge graph.
Step 2: Identify the entity or resource representing "Toulouse."
Step 3: Check if there are any suppliers located in Toulouse.

I will start by searching 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]
I found an entity "Supplier" with the IRI prefix pv:Supplier which represents the supplier of some items. This seems to be the class or entity representing suppliers.

Next, I will search for the entity "Toulouse" in the knowledge graph.

[Tool] No entity items found

[Assistant]
There is no direct entity for "Toulouse" found in the knowledge graph. I will try to find if there is a property related to location or address for suppliers and then check if any of those locations or addresses mention Toulouse as a literal or part of a label.

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

[Assistant] No specific location or address property was found directly for the entity pv:Supplier. I will try a more general search for properties related to location or address in the knowledge graph.

[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

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 relevant properties related to location for suppliers or agents:
- pv:country (country where the supplier is located)
- pv:addressText (address text)
- pv:addressLocality (address locality, e.g., city)

Since Toulouse is a city, the property pv:addressLocality seems most relevant to check if any suppliers have Toulouse as their address locality.

I will now query for suppliers that have pv:addressLocality with the literal "Toulouse".

[User] How many Sensor Switches do we offer?

[Assistant]
To answer the question "How many Sensor Switches do we offer?" I need to identify the entity or class representing "Sensor Switch" in the knowledge graph and then count the instances or products that belong to this category.

Step 1: Search for the entity or class related to "Sensor Switch" in the knowledge graph.

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

[Assistant]
There are two relevant product categories found: "Sensor" and "Switch." Since the question is about "Sensor Switches," it might be a combination of these categories or a specific product category that includes both sensors and switches.

Step 2: Check if there is a specific product category or entity that combines "Sensor" and "Switch" or if products are categorized under both "Sensor" and "Switch." I will first check if there is a product category that explicitly mentions "Sensor Switch."

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

[Assistant]
There is no specific product category explicitly named "Sensor Switch." We have two separate categories: "Sensor" and "Switch."

Step 3: I will now check if there are products that belong to both categories "Sensor" and "Switch." To do this, I will look for products that have a category property linking them to both "prod cat Sensor" and "prod cat Switch."

[Tool] Got no rows and 3 columns

[Assistant] There are no products directly categorized under "prod cat Sensor." I will now check for products categorized under "prod cat Switch" to see if there are any products in that category.

[Tool] Got no rows and 3 columns

[Assistant]
There are no products directly categorized under "prod cat Switch" either.

Step 4: Since there are no products directly categorized under "Sensor" or "Switch," I will try to find products with labels or descriptions containing the keywords "Sensor" and "Switch" to identify Sensor Switch products. I will start by searching for products with "Sensor" in their label.

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

[Assistant]
The search for "Switch" only returned the product category "Switch" again, no individual products.

Step 8: I will now try to list some products in general to see how products are represented and if there is any property or label that can help identify sensor switches. I will list some products to inspect their labels and categories.

[Assistant]
There are no products explicitly typed as "prodi:Product" in the knowledge graph.

Step 9: I will try to find any instance related to products or switches by searching for entities with the keyword "product" or "switch" to understand how products are represented.

[Assistant]
There is an entity "Product" (pv:Product) which represents anything that we make and/or sell.

Step 10: I will now list instances of pv:Product to see if there are any products listed and check their labels to identify sensor switches.

[Assistant]
There are no instances explicitly typed as pv:Product either.

Step 11: I will try to find any entities with the word "Switch" in their label to identify sensor switches by label. I will do a SPARQL query to find entities with "Switch" in their rdfs:label.
