The authors of the paper 'The EMBL Nucleotide Sequence Database' (2005) are available in the DBLP knowledge graph, but no affiliations are recorded for them. The query returns the author IRIs and labels, but the affiliation fields are empty for all authors.

[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:

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

[Assistant]
Let's break down the question:

1. We need to identify the paper titled "The EMBL Nucleotide Sequence Database" in the DBLP knowledge graph.
2. Then, we need to find its authors.
3. Finally, we need to find the affiliations of those authors.

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

[Assistant]
We have retrieved the list of authors for the paper. Now, to answer the full question, we need to find the affiliations of these authors.

The next step is to determine which property in DBLP is used for author affiliations. I will search for properties related to "affiliation".

[Tool]
Top 10 property alternatives:
1. affiliation (dblp:affiliation): A (past or present) affiliation of the creator. (Remark: This pr...ring values until institutions are modelled as proper entities.), creatorNote, Creator
2. primary affiliation (dblp:primaryAffiliation): The primary affiliation of the creator. (Remark: This property c...ring values until institutions are modelled as proper entities.), affiliation, Creator
3. has signature (dblp:hasSignature): A signature that links this publication to an creator., Publication, Signature
4. signature orcid (dblp:signatureOrcid): An ORCID that links the publication to a creator., Signature
5. signature publication (dblp:signaturePublication): The publication of this signature., Publication, Signature
6. published by (dblp:publishedBy): The publisher of the publication. (Remark: This property current...string values until publishers are modelled as proper entities.), Publication
7. title (dblp:title): The title of the publication., Publication
8. isbn (dblp:isbn): An International Standard Book Number., Publication, identifier
9. related stream (dblp:relatedStream): This stream is related to the other stream in some unspecified way., Stream
10. doi (dblp:doi): A Digital Object Identifier., Publication, identifier

[Assistant]
The properties "dblp:affiliation" and "dblp:primaryAffiliation" are relevant for finding author affiliations. Since "dblp:affiliation" is more general, I will use it to retrieve all possible affiliations for each author.

Now, I will construct a SPARQL query to get the authors of the paper and their affiliations, using optional clauses for the affiliations.

[Assistant]
The query successfully retrieved the authors of the paper "The EMBL Nucleotide Sequence Database" (2005), but there are no affiliations or primary affiliations recorded for any of the authors in the DBLP knowledge graph.

Here is the final SPARQL query and the answer:

- The authors of the paper are listed by their DBLP IRIs.
- No affiliations are available for these authors in the DBLP knowledge graph.

If you need the list of authors, you can use the query below. If you need affiliations, they are unfortunately not present in DBLP for this paper.

Feedback (status=done):
The SPARQL query correctly retrieves the authors of the specified paper along with their IRIs and optional affiliation information. Since the DBLP knowledge graph does not contain affiliation data for these authors, the result is as complete as possible given the available data. The query structure is appropriate, and all relevant identifiers are included in the output. 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] Find the year in which the first papers of the authors of 'Enable data privacy, dynamics, and batch in public auditing scheme for cloud storage system' were published.

[Assistant]
From the above, we see that:
- For each author, their publications are linked via `dblp:createdBy`.
- Each publication has a `dblp:yearOfPublication`.

To answer the question, we need for each author:
- All publications where they are `dblp:createdBy`.
- The minimum (earliest) `dblp:yearOfPublication` for those publications.

Let's construct a SPARQL query that, for each of the four authors, finds the earliest publication year.

We will use the IRIs:
- Wanshan Xu: <https://dblp.org/pid/270/5520>
- Zheng Li: <https://dblp.org/pid/10/1143>
- Yilin Yuan: <https://dblp.org/pid/193/8345>
- Jianbiao Zhang: <https://dblp.org/pid/227/4261>

Here's the query.

[Tool]
Failed to call function execute:
failed to parse input: parse error at position 314 for token SELECT with content 'SELECT' (the input most likely does not follow the grammar)

[Assistant]
My previous query was malformed due to incorrect use of subqueries and GROUP BY. Instead, I should use a straightforward aggregation with GROUP BY to get the minimum year for each author.

Let me correct the query:

```sparql
SELECT ?author (MIN(?year) AS ?minYear) WHERE {
  VALUES ?author {
    <https://dblp.org/pid/270/5520>
    <https://dblp.org/pid/10/1143>
    <https://dblp.org/pid/193/8345>
    <https://dblp.org/pid/227/4261>
  }
  ?pub dblp:createdBy ?author .
  ?pub dblp:yearOfPublication ?year .
}
GROUP BY ?author
```

Let's execute this corrected query.

[Tool]

Feedback (status=done):
The SPARQL query correctly retrieves the earliest publication year for each of the specified authors by using the MIN aggregation on the year of publication. The query uses the correct properties (dblp:createdBy and dblp:yearOfPublication) and returns the IRIs of the authors as required. The answer is accurate and complete according to the question's requirements.

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 publications did Chu K. Loo publish in Frontiers Robotics AI?

[Assistant]
Let's break down the question:

1. We need to identify the entity for "Chu K. Loo" (an author).
2. We need to identify the entity for the journal "Frontiers Robotics AI".
3. We need to find publications authored by Chu K. Loo that were published in Frontiers Robotics AI.

First, I will search for the author entity "Chu K. Loo" in the dblp knowledge graph.

[Assistant]
The correct entity for the journal "Frontiers in Robotics and AI" is <https://dblp.org/streams/journals/firai>.

Now, I need to find publications authored by Chu Kiong Loo (<https://dblp.org/pid/71/2077>) that were published in the journal "Frontiers in Robotics and AI" (<https://dblp.org/streams/journals/firai>).

To do this, I will look for publications where:
- The author is Chu Kiong Loo
- The publication is in the journal "Frontiers in Robotics and AI"

I'll construct a SPARQL query to find such publications, returning their IRIs and optionally their titles.

[Tool] Got no rows and 2 columns

[Assistant]
Based on the query results, there are no publications authored by Chu Kiong Loo in the journal "Frontiers in Robotics and AI" in the dblp knowledge graph.

[User] What are the titles of the research papers on Overlay multicast that were published in International Conference on High Performance Computing in the year 2003?

[Assistant]
Let's break down the question:

1. We need to find research papers on "Overlay multicast".
2. These papers must have been published at the "International Conference on High Performance Computing".
3. The publication year should be 2003.
4. We need the titles of these papers.

Step 1: Identify the entity for "International Conference on High Performance Computing" in DBLP.
Step 2: Identify how to filter papers by year (2003).
Step 3: Identify how to filter papers by topic/keyword ("Overlay multicast").
Step 4: Retrieve the titles.

Let's start by searching for the entity corresponding to "International Conference on High Performance Computing".

However, there is also "International Conference on High Performance Computing, Data, and Analytics (HiPC)" (<https://dblp.org/streams/conf/hipc>), which is a well-known conference in this area. But since the user's query exactly matches "International Conference on High Performance Computing", I will proceed with the first entity: <https://dblp.org/streams/conf/hpc2>.

Next, I need to find papers published at this conference in 2003, and filter for those about "Overlay multicast". Let's check how papers are linked to the conference entity and how to filter by year and topic.

I'll list some triples for the conference entity to see how papers are linked.

The search did not return a proceedings entity for "High Performance Computing 2003", but it did return some individual papers, including one with the title "Standards Based High Performance Computing. (2003)". However, these may not be from the specific conference in question.

Given that, let's try a different approach: Let's search for papers with "Overlay multicast" in their title or abstract, and then filter those by publication venue (the conference) and year (2003).

From the search results, I see several papers with "Overlay multicast" in the title, but none are directly linked to the "International Conference on High Performance Computing (HPC)" in 2003. However, one paper from 2003 is "Resilient multicast using overlays" by Suman Banerjee et al., but it is from SIGMETRICS, not HPC.

To be thorough, let's try to list all papers published at "International Conference on High Performance Computing (HPC)" in 2003 and then filter for those with "Overlay multicast" in the title.

First, let's try to find the proceedings or event entity for "International Conference on High Performance Computing (HPC)" in 2003 by searching for "HPC 2003 proceedings".

[Assistant]
The search did not return a specific proceedings entity for "HPC 2003". Since direct search for the proceedings is not yielding results, let's try a different approach:

Let's search for all papers published in 2003 at the "International Conference on High Performance Computing (HPC)" stream and then filter those for "Overlay multicast" in the title.

To do this, I need to check how papers are linked to the conference stream. Let's list triples where the object is the conference stream to see how papers are related.

[Assistant]
Now I see that papers are linked to the conference stream using the property dblp:publishedInStream. Each paper entity also contains the year and title.

Next, let's write a SPARQL query to find all papers published in this stream in 2003, and filter those whose title contains "Overlay multicast". We'll return their IRIs and titles.

I'll proceed to write and execute this query.

[Tool]
SPARQL execution failed:
Invalid SPARQL query: Prefix dct was not registered using a PREFIX declaration

[Assistant]
The error occurred because the prefix dct: was not declared. In the provided prefixes, the correct one is terms: for Dublin Core Terms, which includes issued (publication year). Let's adjust the query to use terms:issued instead of dct:issued.

I'll also ensure dc:title is used for the title, as per the provided prefixes.

Let's try again.

[Tool] Got no rows and 2 columns

[Assistant]
The query returned no results, which means there are no papers with "Overlay multicast" in the title published at the "International Conference on High Performance Computing (HPC)" in 2003 in the DBLP knowledge graph.

To be thorough, let's try a broader search: instead of filtering for "Overlay multicast" in the title, let's check for "multicast" in the title to see if there are any related papers, and then we can further filter if needed.

[Tool] Got no rows and 2 columns

[Assistant]
There are no papers with "multicast" in the title published at the "International Conference on High Performance Computing (HPC)" in 2003 in the DBLP knowledge graph.

Therefore, the answer is that there are no research papers on Overlay multicast published at the International Conference on High Performance Computing in 2003, according to the DBLP knowledge graph.

Feedback (status=done):
The SPARQL query is well-constructed for the user's question. It correctly restricts results to papers published in the International Conference on High Performance Computing (using the correct stream IRI), in the year 2003, and whose titles contain 'overlay multicast' (case-insensitive). It also returns the paper IRIs and their titles, as required by best practices. Since the query returns no results, the answer provided is accurate and complete. No further refinement is necessary.

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] Was a paper not not co-authored by P. H. Guzzi and Marianna Milano?

[Assistant]
Let's break down the question:

- The question is: "Was a paper not not co-authored by P. H. Guzzi and Marianna Milano?"
- The double negative "not not" simplifies to "Was a paper co-authored by P. H. Guzzi and Marianna Milano?"

So, the question is asking if there exists at least one paper co-authored by both P. H. Guzzi and Marianna Milano.

Step 1: Find the entities for "P. H. Guzzi" and "Marianna Milano" in the DBLP knowledge graph.

Step 2: Check if there is a publication (paper) that has both as authors.

Step 3: Since the question is yes/no, we should use an ASK query.

Let's start by searching for the entities for "P. H. Guzzi" and "Marianna Milano".

Feedback (status=done):
The answer and the SPARQL query are correct. The question, with its double negation, asks if there exists a paper co-authored by both P. H. Guzzi and Marianna Milano. The ASK query checks for the existence of such a paper, and the result is False, which matches the answer provided. The query returns the actual identifiers as required, and no further refinement is necessary.
