Using off-the-shelf LLMs to query enterprise data by progressively revealing ontologies

Autor: Civili, C., Sherkhonov, E., Stirewalt, R. E. K.

Ontologies are known to improve the accuracy of Large Language Models (LLMs) when translating natural language queries into a formal query language like SQL or SPARQL. There are two ways to leverage ontologies when working with LLMs. One is to fine-t

Expanded acyclic queries: Containment and an application in explaining missing answers

Autor: Sherkhonov, E.

The first part of this thesis concerns the query containment problem, a fundamental static analysis problem in database theory. Given two queries in a language under consideration, the containment problem is to decide whether the answers of one query

Data exchange is the problem of transforming data structured according to a source schema into data structured according to a target schema, via a mapping specified by means of rules in the form of source-to-target tuple generating dependencies - rul

In this paper, we study the problem of exchanging knowledge between a source and a target knowledge base (KB), connected through mappings. Differently from the traditional database exchange setting, which considers only the exchange of data, we are i
