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 are the top 5 suppliers with best average reliability over their products.

[Assistant]
Let's break down the question:

1. Entities: "suppliers" and "products".
2. Property: "reliability" (likely a numeric value associated with products, possibly per supplier-product pair).
3. Task: For each supplier, calculate the average reliability over all their products, then return the top 5 suppliers with the highest average reliability.

Step 1: Find how suppliers, products, and reliability are represented in the knowledge graph. I'll start by searching for "supplier".

[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]
We have found:
- Supplier class: pv:Supplier
- Property: pv:hasSupplier (links Product to Supplier)

Next, let's search for "product" to confirm its representation.

[Tool]
Top 10 entity alternatives:
1. Product (pv:Product): Anything that we make and/or sell.
2. Product Category (pv:ProductCategory): The category of a product.
3. compatible product (pv:compatibleProduct): A compatible product., has domain Product, has range Product
4. has product manager (pv:hasProductManager): The employee acting as the product manager of the product., has range Employee, has domain Product
5. product outlined svg?color=#D6AF00&format=svg (<https://api.iconify.design/ant-design/product-outlined.svg?color=%23D6AF00&format=svg>)
6. Products - Integration (prodi:)
7. pv: Products - Vocab (pv:): Example vocabulary modeled from a simple sentence about products and services.

[Assistant]
We have:
- Product class: pv:Product

Now, let's search for how "reliability" is represented, as this is the key metric for ranking.

[Tool]
Top 10 property alternatives:
1. has reliability index (pv:reliabilityIndex): A computed KPI to have an reliablity indicator in the context of a supply chain., has domain Hardware
2. compatible product (pv:compatibleProduct): A compatible product., has domain Product, has range Product
3. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
4. quantity (pv:quantity): The quantity needed., has domain BOM Part
5. is Defined By (rdfs:isDefinedBy)
6. type (rdf:type)
7. name (foaf:name):

8. name (pv:name): The name of something.
9. range (rdfs:range)
10. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country

[Assistant]
The property most likely representing reliability is:
- pv:reliabilityIndex: "A computed KPI to have a reliability indicator in the context of a supply chain." (domain: Hardware)

Let's check if pv:reliabilityIndex is used on pv:Product or if we need to consider a subclass (like Hardware). I'll list some triples with pv:reliabilityIndex to see its usage.

[Assistant]
We have confirmed:
- Hardware products (e.g., prodi:hw-J785-9314350) have a pv:reliabilityIndex and are linked to suppliers via pv:hasSupplier.

Now, to answer the question, we need to:
1. For each supplier, get all their products (hardware) and their reliability indices.
2. Compute the average reliability per supplier.
3. Return the top 5 suppliers with the highest average reliability.

Optionally, we can include supplier labels if available. Let's check if suppliers have a label property (e.g., rdfs:label or pv:name). I'll list properties for a supplier entity.

[Assistant]
Suppliers have both rdfs:label and pv:name properties. We can optionally include these in the results.

Now, let's construct the SPARQL query:
- For each supplier, get all products they supply.
- For each product, get its reliability index.
- Compute the average reliability per supplier.
- Order by average reliability descending, limit 5.
- Optionally, include rdfs:label and pv:name for suppliers.

Let's write and execute the query.

[Tool]
SPARQL execution failed:
Invalid SPARQL query: The target ?label of an AS clause was already used in the query body.

[Assistant]
The error is due to using the same variable (?label) in both OPTIONAL and AS clauses. To fix this, I'll use a different variable in the OPTIONAL clause and then use AS to rename it in the SELECT.

Let's update the query:
- Use ?labelRaw and ?nameRaw in OPTIONAL, then use AS to rename in SELECT.

I'll try again.

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 area of expertise is most relevant among our products, what are the top three skills?

[Assistant]
Let's break down the question:

1. "Which area of expertise is most relevant among our products":
   - I need to identify entities representing "products" and find their associated "areas of expertise".
   - Then, I need to determine which area of expertise is most common or most relevant (likely by count).

2. "What are the top three skills?":
   - For the most relevant area of expertise, I need to find associated "skills".
   - Then, I need to determine the top three skills (likely by count or relevance).

Step 1: Search for entities related to "product" in the knowledge graph to identify how products are represented.

[Tool]
Top 10 entity alternatives:
1. Product (pv:Product): Anything that we make and/or sell.
2. Product Category (pv:ProductCategory): The category of a product.
3. compatible product (pv:compatibleProduct): A compatible product., has domain Product, has range Product
4. has product manager (pv:hasProductManager): The employee acting as the product manager of the product., has range Employee, has domain Product
5. product outlined svg?color=#D6AF00&format=svg (<https://api.iconify.design/ant-design/product-outlined.svg?color=%23D6AF00&format=svg>)
6. Products - Integration (prodi:)
7. pv: Products - Vocab (pv:): Example vocabulary modeled from a simple sentence about products and services.

[Assistant] The main entity for "product" appears to be pv:Product. Next, I need to find how "area of expertise" is linked to products. I'll search for properties related to "expertise" to see if there is a direct or indirect connection between products and areas of expertise.

[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. contributor (dct:contributor)
3. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
4. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
5. vocabulary (void:vocabulary)
6. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
7. name (foaf:name):

8. name (pv:name): The name of something.
9. has manager (pv:hasManager): The manager of the employee., has domain Employee, has range Manager
10. created (dct:created)

[Assistant]
The property pv:areaOfExpertise links an "Agent" to a "Product Category" (the area of expertise). Since products are likely linked to product categories, I need to see how products are associated with product categories.

I'll search for properties related to "category" to find how a pv:Product is linked to a pv:ProductCategory.

[Tool]
Top 10 property alternatives:
1. has category (pv:hasCategory): The category name of a product., has range Product Category, has domain Product
2. label (rdfs:label)
3. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
4. type (rdf:type)
5. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
6. vocabulary (void:vocabulary)
7. name (foaf:name):

8. name (pv:name): The name of something.
9. sub Class Of (rdfs:subClassOf)
10. is Defined By (rdfs:isDefinedBy)

[Assistant]
The property pv:hasCategory links a pv:Product to a pv:ProductCategory.

So, the chain is:
- pv:Product --pv:hasCategory--> pv:ProductCategory
- pv:Agent --pv:areaOfExpertise--> pv:ProductCategory

To find the most relevant area of expertise among our products, I need to:
1. Get all products and their categories.
2. Count the occurrences of each category among products.
3. Identify the most common category (area of expertise).

Next, I need to find the top three skills for that area of expertise. I'll search for properties related to "skill" to see how skills are modeled and linked to product categories or areas of expertise.

[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. type (rdf:type)
3. quantity (pv:quantity): The quantity needed., has domain BOM Part
4. created (dct:created)
5. range (rdfs:range)
6. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
7. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
8. vocabulary (void:vocabulary)
9. name (foaf:name):

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

[Assistant] There is no direct property named "skill", but sometimes skills are modeled as entities or as properties of agents or areas of expertise. Since "area of expertise" is linked to agents, and agents may have skills, I'll search for entities related to "skill" to see how they are represented.

[Tool] No entity items found

[Assistant]
There are no entities directly labeled as "skill" in the knowledge graph. It's possible that skills are modeled differently, perhaps as properties of agents or as part of the area of expertise.

I'll now search for properties of pv:ProductCategory (the area of expertise) to see if any are related to skills or similar concepts.

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

No other items found

[Assistant] There are no properties directly linking "skills" to "ProductCategory" (area of expertise). Since "area of expertise" is a property of "Agent", and skills are often associated with people (agents), I'll check the properties of "Agent" for anything related to "skill".

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

No other items found

[Assistant]
There are no properties directly labeled as "skill" for Agent either. Since "area of expertise" is the closest concept, perhaps the knowledge graph models "skills" as the product categories (areas of expertise) themselves, or perhaps as labels or subcategories.

Given this, I'll proceed in two steps:
1. Find the most common product category among all products (as the most relevant area of expertise).
2. For that product category, see if there are any subcategories, labels, or related properties that could represent "skills".

First, I'll write a query to count the number of products per product category and get the most common one.

[Tool] Got no rows and 2 columns

[Assistant]
The query to count products per category returned no rows, which suggests that either:
- There are no products with the pv:hasCategory property, or
- The data is modeled differently (e.g., different property names, or no instances).

To verify, I'll list some triples where the subject is of type pv:Product to see how products are described and if they have categories or other relevant properties.

[Tool]
Got 5 rows and 3 columns:
| subject              | property                         | object                                                                                |

[Assistant]
The listing for pv:Product only shows schema-level information (class definition, label, comment), not actual product instances. This suggests that product instances may be in a different namespace, such as prodi: (Products - Integration).

I'll search for entities in the prodi: namespace to see if there are product instances there.

[Tool] No entity items found

[Assistant]
There are no entities found in the prodi: namespace either. This suggests that either the knowledge graph does not contain product instances, or they are modeled under a different naming scheme or not indexed for search.

Given that, I'll try a broader approach: list some triples where the property is pv:hasCategory, to see if any products are linked to categories this way.

[Assistant]
Now I see that product instances (e.g., prodi:hw-A145-1240844) are linked to product categories (e.g., prodi:prod-cat-Compensator) via pv:hasCategory.

Next, I will count the number of products per category to find the most common product category (area of expertise).

[Tool]
Got 1 row and 2 columns:

| ------------------------------------------------- | ------------- |
| prod cat Compensator (prodi:prod-cat-Compensator) | 110 (xsd:int) |

[Assistant]
The most relevant area of expertise among our products is "prod cat Compensator" (prodi:prod-cat-Compensator), as it is the most common product category.

Now, I need to find the top three skills associated with this area of expertise. Since "skills" are not directly modeled, I'll look for properties or entities linked to prodi:prod-cat-Compensator that could represent skills, such as subcategories, labels, or related properties.

First, I'll list all triples where prodi:prod-cat-Compensator is the subject to see what information is available.

[Tool]
Got 3 rows and 3 columns:

| prod cat Compensator (prodi:prod-cat-Compensator) | name (pv:name)     | Compensator                           |

[Assistant]
There are no direct links from the product category "Compensator" to any "skills". Since skills might be associated with agents (experts) who have this area of expertise, I'll look for agents with pv:areaOfExpertise prodi:prod-cat-Compensator, and see if they have any properties that could represent skills.

First, I'll find agents with area of expertise "prodi:prod-cat-Compensator".

[Assistant]
The agent's properties include area of expertise, but there are no properties directly representing "skills". Since skills are not explicitly modeled, the closest proxy is the set of product categories (areas of expertise) that agents with expertise in "Compensator" also have.

Therefore, I can find the top three additional areas of expertise (product categories) that are most commonly associated with agents who have expertise in "Compensator". These can be interpreted as the top three "skills" relevant to that area.

I'll write a query to:
- Find all agents with area of expertise "Compensator"
- Get all their other areas of expertise (excluding "Compensator" itself)
- Count the occurrences and return the top three

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 products are compatible with the U990 LCD Inductor?

[Assistant]
Let's break down the question:

1. The entity is "U990 LCD Inductor".
2. The property is "compatible with" or "compatibility".

First, I will search for the entity "U990 LCD Inductor" in the knowledge graph to find its IRI.

[Tool]
Top 10 entity alternatives:
1. prod cat LCD (prodi:prod-cat-LCD): is a Product Category
2. prod cat Inductor (prodi:prod-cat-Inductor): is a Product Category
3. hw U990 5234138 (prodi:hw-U990-5234138): is a Hardware
4. bom part 18 U990 5234138 (prodi:bom-part-18-U990-5234138): is a BOM Part
5. bom part 5 U990 5234138 (prodi:bom-part-5-U990-5234138): is a BOM Part
6. price hw U990 5234138 EUR (prodi:price-hw-U990-5234138-EUR): is a Price

[Assistant]
From the search results, there is no exact match for "U990 LCD Inductor" as a single entity, but there are related entities:

- prodi:hw-U990-5234138 (Hardware)
- prodi:bom-part-18-U990-5234138 (BOM Part)
- prodi:bom-part-5-U990-5234138 (BOM Part)

It is likely that "hw U990 5234138" is the hardware product referred to as "U990", and the BOM parts may be components or sub-parts.

Next, I will check if any of these entities have properties related to "compatible with". I will start by searching for properties related to "compatible" for the hardware entity prodi:hw-U990-5234138.

[User] Which coil has the highest density?

[Assistant]
Let's break down the question:

1. The user is asking which "coil" has the highest "density".
2. I need to identify how "coil" and "density" are represented in the knowledge graph.
3. First, I will search for the entity "coil" to see how coils are represented.
4. Then, I will search for properties related to "density" to find the correct property.

Let's start by searching for the entity "coil".

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

[Assistant]
The search result shows that "Coil" is represented as a product category: prodi:prod-cat-Coil.

Next, I need to find instances (individual coils) that belong to this product category. Usually, there is a property like "has product category" or "type" linking products to their category.

I will search for properties related to "product category" to find how products are linked to prodi:prod-cat-Coil.

[Tool]
Top 10 property alternatives:
1. has category (pv:hasCategory): The category name of a product., has range Product Category, has domain Product
2. label (rdfs:label)
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. sub Class Of (rdfs:subClassOf)
6. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
7. quantity (pv:quantity): The quantity needed., has domain BOM Part
8. type (rdf:type)
9. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
10. is Defined By (rdfs:isDefinedBy)

[Assistant]
The property pv:hasCategory is used to link products to their product category, which in this case is prodi:prod-cat-Coil.

Now, I need to find all products with pv:hasCategory prodi:prod-cat-Coil.

Next, I need to find the property representing "density". I will search for properties related to "density".

[Tool]
Top 10 property alternatives:
1. quantity (pv:quantity): The quantity needed., has domain BOM Part
2. weight (g) (pv:weight_g): The weight of an item measured in grams., has domain Hardware
3. depth (mm) (pv:depth_mm): The depth of an item measured in millimeter., has domain Hardware
4. height (mm) (pv:height_mm): The height of an item measured in millimeter., has domain Hardware
5. type (rdf:type)
6. amount (pv:amount): has domain Price, The amount.
7. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
8. lat (wgs84:lat)
9. is Defined By (rdfs:isDefinedBy)
10. width (mm) (pv:width_mm): The width of an item measured in millimeter., has domain Hardware

[Assistant]
The search did not return a property explicitly named "density". However, sometimes density might be represented as a custom property or as a data property with a different name.

To be thorough, I will search for properties of a specific coil product to see if any property related to density exists. First, I need to find an example coil product. I will list some products with pv:hasCategory prodi:prod-cat-Coil.

[Assistant]
There is no property explicitly named "density" for the coil product. However, properties like weight (pv:weight_g), depth (pv:depth_mm), height (pv:height_mm), and width (pv:width_mm) are available. Density could potentially be calculated if volume and weight are available.

Density = weight / volume

Volume for a rectangular object = width × height × depth (assuming these are the dimensions).

Let's check if all three dimensions (width, height, depth) and weight are available for coil products. I will list these properties for a few coil products.

[Assistant]
It appears there was a technical issue and I repeated the same step multiple times. From the previous results, I see that for prodi:hw-A145-1240844, the properties "depth (mm)", "width (mm)", "height (mm)", and "weight (g)" are available.

Therefore, I can calculate density for each coil as:
density = weight (g) / (width (mm) * height (mm) * depth (mm))

Now, I will write a SPARQL query to:
- Select all products with pv:hasCategory prodi:prod-cat-Coil
- Retrieve their weight, width, height, and depth
- Calculate density as described above
- Return the coil with the highest density

Let's construct and execute this query.
