Enhancing Conversational Search: Large Language Model-Aided Informative Query Rewriting
Conference on Empirical Methods in Natural Language Processing, 2023Query rewriting plays a vital role in enhancing conversational search by transforming context-dependent user queries into standalone forms. Existing approaches primarily leverage human-rewritten queries as labels to train query rewriting models. However,

ACM SIGMOD Record, 2021
Due to the importance of linear algebra and matrix operations in data analytics, there has been a renewed interest in developing query languages that combine both standard relational operations and linear algebra operations. We survey aspects of the matrix query language MATLANG and extensions thereof, and connect matrix query languages to classical ...

The t4sql temporal query language [PDF]
Proceedings of the sixteenth ACM conference on Conference on information and knowledge management, 2007 Time characterizes every aspect of our life and its management when storing and querying data is very important. In this paper we propose a new temporal query language, called T4SQL, supporting multiple temporal dimensions of data. Besides the well-known valid and transaction times, it encompasses two additional temporal dimensions, namely ...

An object query language for fuzzy querying [PDF]
Database and Expert Systems Applications. 8th International Conference, DEXA '97. Proceedings, 2002 Fuzzy querying systems allow queries to be more or less satisfied. Then, the results of a query are ranked according to their degree of satisfaction. The need for fuzzy querying systems has increased since the arrival of multimedia data in the field of database management systems.

On the structure of queries in constraint query languages [PDF]
Proceedings 11th Annual IEEE Symposium on Logic in Computer Science, 2002 We study the structure of first-order and second-order queries over constraint databases. Constraint databases are formally modeled as finite relational structures embedded in some fixed infinite structure. We concentrate on problems of elimination of constraints, reducing quantification range to the active domain of the database and obtaining new ...
