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:

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. Use the functions to search for 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. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
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 assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. 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.
4. 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.
5. 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.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. 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] List the authors of 'Formal Metadata and Shared Experiences for Discovering Tools to Adapt Open Educational Resources' and their affiliations.

[Assistant]
Let's break down the question:

1. We need to find the publication titled 'Formal Metadata and Shared Experiences for Discovering Tools to Adapt Open Educational Resources'.
2. Then, we need to list its authors.
3. For each author, we need to find their affiliations.

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

From the triples, I see that the paper has the following author-related properties:
- dblp:createdBy
- dblp:authoredBy

Both point to Jianhu Zhao (<https://dblp.org/pid/34/5431>). However, the property dblp:numberOfCreators indicates there are 4 creators, so there must be more authors.

I'll look for all triples with the property dblp:authoredBy for this paper to get all authors.

The four authors of the paper are:

2. Xinhua Chen (<https://dblp.org/pid/24/1926>)
3. Jie Feng (<https://dblp.org/pid/24/7003>)
4. An author with IRI <https://dblp.org/pid/36/687-2> (name not shown here, but the IRI is sufficient for querying).

Now, I need to count the number of papers each of these authors published in 2018, and sum the total.

I'll construct a SPARQL query that counts all distinct papers authored by any of these four authors in 2018.

Feedback (status=done):
The SPARQL query correctly identifies papers co-authored by both Song Zheng and Bi, Qinsheng in the journal 'Appl. Math. Comput.' (Applied Mathematics and Computation). It uses the correct properties to filter by both authors and the publication venue. The query returns the IRIs of the papers and optionally their titles, following the guidelines. The answer is accurate and complete based on the execution result. No further refinement is needed.

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. Use the functions to search for 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. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
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 assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. 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.
4. 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.
5. 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.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. 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 average number of co-authors for research papers published by Y. Ma?

[Assistant]
Let's break down the question:

1. We need to identify the entity for "Y. Ma" in the DBLP knowledge graph.
2. For each research paper authored by Y. Ma, we need to count the number of co-authors (excluding Y. Ma themselves).
3. We need to compute the average number of co-authors per paper.

First, let's search for the entity corresponding to "Y. Ma" in DBLP.

[Tool] No entity items found

[Assistant]
It appears that there is no direct entity for "Y. Ma" in the DBLP knowledge graph, at least not under that exact name. This could be due to the way author names are disambiguated or stored in DBLP (e.g., with full names, initials, or unique identifiers).

Without a resolvable entity for "Y. Ma", I cannot construct a precise SPARQL query to answer your question. If you can provide more information about the author (such as a full name, affiliation, or a specific paper), I could try searching again with that information. Alternatively, if you have a DBLP author ID for Y. Ma, that would help as well.

Let me know if you have more details, or if you'd like me to try searching with a different query!

[User] What bibtex type of publication is 'Using Interaction as Nudge to Increase Installation Rate of COVID-19 Contact-Confirming Application'?

[Assistant]
Let's break down the question:

1. We need to find the publication titled "Using Interaction as Nudge to Increase Installation Rate of COVID-19 Contact-Confirming Application" in the DBLP knowledge graph.
2. Then, we need to determine its bibtex type (e.g., article, inproceedings, etc.).

First, I will search for the publication entity using its title.

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. Use the functions to search for 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. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
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 assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. 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.
4. 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.
5. 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.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. 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] Does Abdel Magid S. Hamouda have an ORCID?

[Assistant]
To answer this question, I need to:

1. Find the entity for "Abdel Magid S. Hamouda" in the DBLP knowledge graph.
2. Identify the property used for ORCID in DBLP.
3. Check if the author entity has an ORCID property.

Let's start by searching for the entity "Abdel Magid S. Hamouda".

[Assistant]
The top result for "Abdel Magid S. Hamouda" is the entity <https://dblp.org/pid/79/5370>, which matches the full name.

Next, I need to determine which property in DBLP is used for ORCID identifiers. I'll search for properties related to "ORCID".

[User] In which year did David P. Chassin publish their last paper?

[Assistant]
Let's break down the question:

1. We need to identify the entity for "David P. Chassin" in the DBLP knowledge graph.
2. We need to find all papers authored by this person.
3. For each paper, we need to get its publication year.
4. We need to find the latest (maximum) year among these.

Let's start by searching for the entity "David P. Chassin" in DBLP.

[Tool]
Top 10 entity alternatives:
1. David P. Chassin, also known as David P. Chassin (<https://dblp.org/pid/21/151>)

10. David P. Paper, also known as David P. Paper (<https://dblp.org/pid/38/2596>)

[Assistant]
The top match for "David P. Chassin" is the entity <https://dblp.org/pid/21/151>.

Next, I need to find all papers authored by this person and retrieve their publication years. Then, I will determine the latest year among them.

To do this, I will:
- Find papers where <https://dblp.org/pid/21/151> is an author.
- Retrieve the publication year for each paper.
- Select the maximum year.

Let's construct the SPARQL query for this.

[Tool] Got no rows and 1 columns

[Assistant]
It appears that my initial attempt did not return any results. This could be due to the property used for author or year not matching the actual properties in the DBLP knowledge graph.

Let me investigate which properties are used for linking papers to authors and for specifying the publication year. I will start by listing some properties of the author entity <https://dblp.org/pid/21/151>.

[Tool]
Got 6 rows and 3 columns:

[Assistant]
The author entity itself does not directly link to papers. Instead, papers likely link to their authors. I need to find which property is used on paper entities to indicate their authors.

I'll search for properties related to "author" in the DBLP knowledge graph to find the correct property.

[Tool]
Top 10 property alternatives:
1. authored by (dblp:authoredBy): The publication is authored by the creator., Publication, createdBy, Creator
2. published by (dblp:publishedBy): The publisher of the publication. (Remark: This property current...string values until publishers are modelled as proper entities.), Publication
3. edited by (dblp:editedBy): The publication is edited by the creator., Publication, createdBy, Creator
4. published in (dblp:publishedIn): The name of the series, the journal, or the book in which the pu...journals and conference series are modelled as proper entities.), Publication
5. published in book (dblp:publishedInBook): The name of the book in which the publication has been published...journals and conference series are modelled as proper entities.), Publication, publishedIn
6. creator name (dblp:creatorName): The full name of the creator., Creator

8. published in series (dblp:publishedInSeries): The name of the series in which the publication has been publish...journals and conference series are modelled as proper entities.), Publication, publishedIn

10. published in book chapter (dblp:publishedInBookChapter): The chapter of the book in which the publication has been publis...journals and conference series are modelled as proper entities.), Publication

[Assistant]
The most relevant property for linking papers to authors appears to be dblp:authoredBy. For the publication year, the property is likely dblp:yearOfPublication.

Let's confirm the usage of these properties by listing some triples where dblp:authoredBy is used.

The property dblp:authoredBy is indeed used to link publications to author entities. Now, let's check which property is used for the publication year by listing properties of a sample publication.

I'll pick one of the publication IRIs from the previous result and list its properties. Let's use <https://dblp.org/rec/books/el/15/RosingSetal15>.

[Assistant]
The property dblp:yearOfPublication is used for the publication year.

Now, I will construct a SPARQL query to:
- Find all papers where dblp:authoredBy <https://dblp.org/pid/21/151>
- Get their dblp:yearOfPublication
- Return the maximum year

Let's write the query accordingly.

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. Use the functions to search for 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. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
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 assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. 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.
4. 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.
5. 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.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. 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 Wikidata ID of Kreinovich, V.?

[Assistant]
To answer this question, I need to:

1. Identify the entity for "Kreinovich, V." in the DBLP knowledge graph.
2. Find the property that links DBLP authors to their Wikidata IDs.
3. Construct a SPARQL query to retrieve the Wikidata ID for "Kreinovich, V."

First, I'll search for the entity "Kreinovich, V." in DBLP.

[Tool]
Top 10 entity alternatives:
1. Vladik Kreinovich, also known as Vladik Kreinovich (<https://dblp.org/pid/k/VladikKreinovich>)
2. Vladik Kreinovich: Paul Erdös, 1913-1996. (1996) (<https://dblp.org/rec/journals/rc/Kreinovich96c>)

5. Vladik Kreinovich: Letters to the editor. (1993) (<https://dblp.org/rec/journals/nn/Kreinovich93>)
6. Vladik Kreinovich et al.: Robustness in Econometrics (2017) (<https://dblp.org/rec/series/sci/2017-692>)

10. Vladik Kreinovich: Interval Meth...Knowledge Representation. (2019) (<https://dblp.org/rec/journals/ijufks/Kreinovich19d>)

[Assistant]
The top result for "Kreinovich, V." is "Vladik Kreinovich" with the DBLP IRI: <https://dblp.org/pid/k/VladikKreinovich>. This is likely the correct author entity.

Next, I need to find the property in DBLP that links an author to their Wikidata ID. I'll search for properties related to "Wikidata" in the DBLP knowledge graph.

Top 10 property alternatives:
1. wikidata (dblp:wikidata): A wikidata item., identifier, Entity

8. issn (dblp:issn): An International Standard Serial Number., identifier, Stream
9. creator name (dblp:creatorName): The full name of the creator., Creator
10. published in (dblp:publishedIn): The name of the series, the journal, or the book in which the pu...journals and conference series are modelled as proper entities.), Publication

[Assistant]
The property "dblp:wikidata" is described as "A wikidata item." and is likely used to link DBLP entities to their corresponding Wikidata IDs.

Now, I'll construct a SPARQL query to retrieve the Wikidata ID for the author entity <https://dblp.org/pid/k/VladikKreinovich> using the "dblp:wikidata" property.
