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 ...

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,

Natural language query filtration in the Conceptual Query Language
Proceedings of the Thirtieth Hawaii International Conference on System Sciences, 2002Natural language (NL) interfaces for database query formulation have always been recognized as a much needed enhancement for end-users. Poor performances with earlier NL systems had led to a lull in research in this field. However, latter-day experiments and systems appear to be sufficiently more promising to warrant continued and further research in ...

An object query language for fuzzy querying
Database and Expert Systems Applications. 8th International Conference, DEXA '97. Proceedings, 2002Fuzzy 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
Proceedings 11th Annual IEEE Symposium on Logic in Computer Science, 2002We 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 ...

2018 56th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2018
In this paper, we introduce an enhanced schema-less database language that supports prediction queries natively-the Prediction Query Language (PQL). Data in the PQL representation can be naturally modeled as an exchangeable multi-dimensional array. The seminal result by Aldous and Hoover (1980s), generalizing the classical result of De Finetti (1937 ...
