FOSDEM 2013 - Flexible Graph Querying using the FlexIt Querying Language

Flex-It is a declarative query language allowing users to query graph data whose structure is complex, not fully-known or ever-changing, or where there is a requirement for the intelligent exploration of a graph. Flex-It performs both approximate matching and relaxation of the user's query, and ranks the answers according to how closely they match the original query. This is of especial relevance in areas where there are large volumes of complex, heterogeneous data with ever-evolving schemas; these include bioinformatics (and other scientific disciplines), financial information and social networks, among others.

I have been developing applications for over 15 years across a variety of different technology stacks and industry sectors. I am currently employed at UCL's Institute of Neurology, developing a system aggregating large, heterogeneous datasets. I am also doing a part-time PhD at Birkbeck College, University of London, researching and developing a query language enabling users to query graph data in a flexible fashion. The focus is also on optimising the execution of these queries over large, complex datasets.
