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:
dblp at https://qlever.cs.uni-freiburg.de/api/dblp with notes:
1. Use dblp:authoredBy to reliably link publications to authors. Query from the publication side for author-publication relationships, as direct links from author entities may be incomplete or missing.
2. dblp:publishedIn and dblp:publishedInStream are both used for venues; publishedIn can be a string or entity, while publishedInStream is always an entity. Prefer publishedInStream when available for reliable venue queries.
3. For publication year, use dblp:yearOfPublication (xsd:gYear) from the publication entity. The property dblp:year is often missing or unreliable.
4. SPARQL queries with GROUP BY, LIMIT, ORDER BY, or aggregate functions (MIN, MAX, AVG) may not work as expected in dblp. Retrieve all grouped results and post-process to find min/max/avg or desired ordering.
5. Publication titles and venue labels may be inconsistently present (dc:title, rdfs:label, schema:name, dblp:title). Use OPTIONAL for all likely properties. If data is missing, use the list function to inspect all properties for alternatives.
6. When searching for authors or venues, multiple candidates may be returned. Use additional context (e.g., co-authors, publication titles, years) to disambiguate and select the correct entity.
7. For venue queries, try both entity IRIs (e.g., streams) and string literals, as some publications may only be linked via one or the other. Consider using FILTER or UNION to cover both cases.
8. For negative authorship or publication existence queries, use FILTER NOT EXISTS in ASK queries to check for the absence of a relationship (e.g., not authored by a specific person).
9. dblp:title is an additional property for publication titles. If dc:title, rdfs:label, or schema:name are missing, check dblp:title as it may contain the full or canonical title.
10. Affiliation data (e.g., primaryAffiliation) for authors is often missing or unreliable in dblp. Queries about author institutions or collaborations based on affiliation may not yield results or may require external validation.

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] Mention the publication on Cloud environments that was published by Chothia in CoRR.

[Assistant]
Let's break down the question:

- We are looking for a publication about "Cloud environments".
- The author should be "Chothia".
- The publication venue should be "CoRR".

Step 1: Identify the entity for "Chothia".
Step 2: Identify the entity for "CoRR".
Step 3: Search for publications authored by Chothia, published in CoRR, and related to "Cloud environments".

Let's start by searching for the author "Chothia" in the dblp knowledge graph.

[Assistant]
We have identified the following:

- The venue "CoRR" corresponds to the entity: https://dblp.org/streams/journals/corr
- There are three possible "Chothia" authors: Cyrus, Zaheer, and Tom.

Next, I will search for publications authored by any of these "Chothia" authors, published in CoRR, and related to "Cloud environments".

First, let's check the IRIs for the three "Chothia" authors:
- Cyrus Chothia: https://dblp.org/pid/86/713
- Zaheer Chothia: https://dblp.org/pid/151/7519
- Tom Chothia: https://dblp.org/pid/30/3919

Now, I will construct a query to find publications that:
- Are authored by any of these three Chothias,
- Are published in CoRR (using dblp:publishedInStream),
- Have a title or subject mentioning "Cloud environments" (using FILTER with "cloud" as a keyword).

I will include optional title properties to maximize the chance of finding relevant publications.

[Tool] Got no rows and 3 columns

[Assistant] The query found no publications authored by any of the Chothia authors (Cyrus, Zaheer, or Tom) in CoRR with a title containing "cloud" (as in "Cloud environments"). Therefore, based on the current data in dblp, there is no publication on Cloud environments published by Chothia in CoRR.

[Assistant]
Let's break down the question:

1. The user is asking whether the publication titled "Design considerations of sub-mW indoor light energy harvesting for wireless sensor systems" was published in the year 2010.
2. To answer this, I need to:
   - Find the publication entity with this title in the dblp knowledge graph.
   - Check its year of publication using the property dblp:yearOfPublication.
   - Compare the year to 2010 and return True or False.

Step 1: Search for the publication entity by title.
Step 2: Check the year of publication.

First, I'll search for the publication entity using the title.

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:
dblp at https://qlever.cs.uni-freiburg.de/api/dblp with notes:
1. Use dblp:authoredBy to reliably link publications to authors. Query from the publication side for author-publication relationships, as direct links from author entities may be incomplete or missing.
2. dblp:publishedIn and dblp:publishedInStream are both used for venues; publishedIn can be a string or entity, while publishedInStream is always an entity. Prefer publishedInStream when available for reliable venue queries.
3. For publication year, use dblp:yearOfPublication (xsd:gYear) from the publication entity. The property dblp:year is often missing or unreliable.
4. SPARQL queries with GROUP BY, LIMIT, ORDER BY, or aggregate functions (MIN, MAX, AVG) may not work as expected in dblp. Retrieve all grouped results and post-process to find min/max/avg or desired ordering.
5. Publication titles and venue labels may be inconsistently present (dc:title, rdfs:label, schema:name, dblp:title). Use OPTIONAL for all likely properties. If data is missing, use the list function to inspect all properties for alternatives.
6. When searching for authors or venues, multiple candidates may be returned. Use additional context (e.g., co-authors, publication titles, years) to disambiguate and select the correct entity.
7. For venue queries, try both entity IRIs (e.g., streams) and string literals, as some publications may only be linked via one or the other. Consider using FILTER or UNION to cover both cases.
8. For negative authorship or publication existence queries, use FILTER NOT EXISTS in ASK queries to check for the absence of a relationship (e.g., not authored by a specific person).
9. dblp:title is an additional property for publication titles. If dc:title, rdfs:label, or schema:name are missing, check dblp:title as it may contain the full or canonical title.
10. Affiliation data (e.g., primaryAffiliation) for authors is often missing or unreliable in dblp. Queries about author institutions or collaborations based on affiliation may not yield results or may require external validation.

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 year was 'Server-side object recognition and client-side object tracking for mobile augmented reality' published?

[Assistant]
Let's break down the question:

1. The user is asking for the publication year of a specific paper: "Server-side object recognition and client-side object tracking for mobile augmented reality".
2. To answer, I need to:
   - Find the publication entity for this title in DBLP.
   - Retrieve its year of publication, using the property dblp:yearOfPublication (xsd:gYear).

Step 1: Search for the publication entity by its title.

[User] In 1997 in ASP-DAC, who are the authors that published papers about Decision diagrams?

[Assistant]
Let's break down the question:

- We are looking for authors.
- The papers must be published in 1997.
- The venue is ASP-DAC (Asia and South Pacific Design Automation Conference).
- The papers must be about "Decision diagrams".

Step 1: Identify the entity for ASP-DAC in dblp.
Step 2: Find the property for publication year (should be dblp:yearOfPublication).
Step 3: Find how to filter for papers about "Decision diagrams" (likely in the title).
Step 4: Retrieve the authors for those papers.

Let's start by searching for the ASP-DAC venue entity in dblp.

[Tool]
Top 10 entity alternatives:
1. Hidetoshi Onodera: 2016 ASP-DAC. (2016) (<https://dblp.org/rec/journals/dt/Onodera16>)

10. 25th Asia and South Pacific Desi...hina, January 13-16, 2020 (2020) (<https://dblp.org/rec/conf/aspdac/2020>)

[Assistant]
The correct entity for the ASP-DAC venue is:
<https://dblp.org/streams/conf/aspdac>

Next, I need to find publications from 1997 in this venue, and filter for those with "Decision diagrams" in the title, then retrieve their authors.

I'll now check which property links a publication to its venue stream, and confirm the year property.

Has Martin Skutella not not published the paper 'An FPTAS for Quickest Multicommodity Flows with Inflow-Dependent Transit Times'?

[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:
dblp at https://qlever.cs.uni-freiburg.de/api/dblp with notes:
1. Use dblp:authoredBy to reliably link publications to authors. Query from the publication side for author-publication relationships, as direct links from author entities may be incomplete or missing.
2. dblp:publishedIn and dblp:publishedInStream are both used for venues; publishedIn can be a string or entity, while publishedInStream is always an entity. Prefer publishedInStream when available for reliable venue queries.
3. For publication year, use dblp:yearOfPublication (xsd:gYear) from the publication entity. The property dblp:year is often missing or unreliable.
4. SPARQL queries with GROUP BY, LIMIT, ORDER BY, or aggregate functions (MIN, MAX, AVG) may not work as expected in dblp. Retrieve all grouped results and post-process to find min/max/avg or desired ordering.
5. Publication titles and venue labels may be inconsistently present (dc:title, rdfs:label, schema:name, dblp:title). Use OPTIONAL for all likely properties. If data is missing, use the list function to inspect all properties for alternatives.
6. When searching for authors or venues, multiple candidates may be returned. Use additional context (e.g., co-authors, publication titles, years) to disambiguate and select the correct entity.
7. For venue queries, try both entity IRIs (e.g., streams) and string literals, as some publications may only be linked via one or the other. Consider using FILTER or UNION to cover both cases.
8. For negative authorship or publication existence queries, use FILTER NOT EXISTS in ASK queries to check for the absence of a relationship (e.g., not authored by a specific person).
9. dblp:title is an additional property for publication titles. If dc:title, rdfs:label, or schema:name are missing, check dblp:title as it may contain the full or canonical title.
10. Affiliation data (e.g., primaryAffiliation) for authors is often missing or unreliable in dblp. Queries about author institutions or collaborations based on affiliation may not yield results or may require external validation.

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] Has Martin Skutella not not published the paper 'An FPTAS for Quickest Multicommodity Flows with Inflow-Dependent Transit Times'?

[Assistant]
Let's break down the question:

- The question is: "Has Martin Skutella not not published the paper 'An FPTAS for Quickest Multicommodity Flows with Inflow-Dependent Transit Times'?"
- The double negative ("not not") means we are being asked if Martin Skutella has published this paper.

Step 1: Identify the entities:
- Author: Martin Skutella
- Paper: 'An FPTAS for Quickest Multicommodity Flows with Inflow-Dependent Transit Times'

Step 2: Find the IRIs for the author and the publication.

I'll first search for Martin Skutella in the dblp knowledge graph.

The top result for "Martin Skutella" is the author entity: <https://dblp.org/pid/80/2691>.

Next, I will search for the publication with the title 'An FPTAS for Quickest Multicommodity Flows with Inflow-Dependent Transit Times' to find its entity or record in dblp.

There are several closely matching publications. The top two are:

1. Alexander Hall et al.: An FPTAS ...-Dependent Transit Times. (2003) (<https://dblp.org/rec/conf/random/HallLS03>)
2. Alexander Hall et al.: An FPTAS ...-Dependent Transit Times. (2007) (<https://dblp.org/rec/journals/algorithmica/HallLS07>)

The ellipsis in the title suggests truncation, but both are likely referring to the paper in question. Let's check if Martin Skutella is among the authors of either or both of these publications.

I will now query the authors of these two publications to see if Martin Skutella (<https://dblp.org/pid/80/2691>) is listed.

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] Didn't Eckardt, Barbara Von not publish in 2001?

[Assistant]
Let's break down the question:

- The user is asking if "Eckardt, Barbara Von" did NOT publish in 2001.
- This is a negative authorship query for a specific year.
- According to the notes, for negative authorship or publication existence queries, we should use FILTER NOT EXISTS in an ASK query.

Step 1: Find the correct author entity for "Eckardt, Barbara Von" in dblp.
Step 2: Check if there exists any publication authored by this person with yearOfPublication 2001.
Step 3: Use an ASK query with FILTER NOT EXISTS to check for the absence of such a publication.

First, let's search for the author entity.

Who are the authors of the paper 'The EMBL Nucleotide Sequence Database' and what are their affiliations?

[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:
dblp at https://qlever.cs.uni-freiburg.de/api/dblp with notes:
1. Use dblp:authoredBy to reliably link publications to authors. Query from the publication side for author-publication relationships, as direct links from author entities may be incomplete or missing.
2. dblp:publishedIn and dblp:publishedInStream are both used for venues; publishedIn can be a string or entity, while publishedInStream is always an entity. Prefer publishedInStream when available for reliable venue queries.
3. For publication year, use dblp:yearOfPublication (xsd:gYear) from the publication entity. The property dblp:year is often missing or unreliable.
4. SPARQL queries with GROUP BY, LIMIT, ORDER BY, or aggregate functions (MIN, MAX, AVG) may not work as expected in dblp. Retrieve all grouped results and post-process to find min/max/avg or desired ordering.
5. Publication titles and venue labels may be inconsistently present (dc:title, rdfs:label, schema:name, dblp:title). Use OPTIONAL for all likely properties. If data is missing, use the list function to inspect all properties for alternatives.
6. When searching for authors or venues, multiple candidates may be returned. Use additional context (e.g., co-authors, publication titles, years) to disambiguate and select the correct entity.
7. For venue queries, try both entity IRIs (e.g., streams) and string literals, as some publications may only be linked via one or the other. Consider using FILTER or UNION to cover both cases.
8. For negative authorship or publication existence queries, use FILTER NOT EXISTS in ASK queries to check for the absence of a relationship (e.g., not authored by a specific person).
9. dblp:title is an additional property for publication titles. If dc:title, rdfs:label, or schema:name are missing, check dblp:title as it may contain the full or canonical title.
10. Affiliation data (e.g., primaryAffiliation) for authors is often missing or unreliable in dblp. Queries about author institutions or collaborations based on affiliation may not yield results or may require external validation.
