Towards Large Knowledge Bases

Participants : Jean-François Baget, Madalina Croitoru, Bruno Paiva Lima Da Silva.

We have began to study different storage solutions for large databases, first as part of a Master's thesis, and now with the PhD of Bruno Paiva Lima da Silva [29] . The goal of this work is to evaluate different storage paradigms and systems (e.g., relational databases MySQL and Sqlite; triple stores Sesame and graph databases Neo4J, DEX, HyperGraphDB and OrientDB) with respect to our particular requirements (mainly ontological conjunctive query answering with large knowledge bases), and to integrate them in a unified way in a software tool (answering our genericity requirement and paving the way for hybrid KBs). We believe this work to be a necessary step for our next generation of software tools.
