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

Rule learning over knowledge graphs with genetic logic programming

Autor: Wu, L, Sallinger, E, Sherkhonov, E, Vahdati, S, Gottlob, G

Declarative rules such as Prolog and Datalog rules are common formalisms to express expert knowledge and facts. They play an important role in Knowledge Graph (KG) construction and completion. Such rules not only encode the expert background knowledg

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

Knowledge base exchange can be considered as a generalization of data exchange in which the aim is to exchange between a source and a target connected through mappings, not only explicit knowledge, i.e., data, but also implicit knowledge in the form
