The LIP6 Database research team has a long experience of research in large-scale data processing. Its research activities cover a variety of big data processing issues. The main challenges of the last few years concern the acquisition and indexing of web archives, distributed transaction processing, information filtering and recommendation in social media, JSON schema extraction, graph data processing, and data enrichment.
