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 ...

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 ...

North American Chapter of the Association for Computational Linguistics
Retrieval-Augmented Large Language Models (LLMs), which incorporate the non-parametric knowledge from external knowledge bases into LLMs, have emerged as a promising approach to enhancing response accuracy in several tasks, such as Question-Answering (QA)

The query language reflects all of the system functional requirements discussed in the preceding chapter, because it is the interface between the user of the file system and the automated search and storage components of the system. Hence, all of the design capabilities that are built into the file system by virtue of its structure must be made ...
