X-IOTA : An open XML framework for IR experimentation. Application on multiple weighing scheme tests in a bilingual corpus
Résumé
Carrying out experiments in Information Retrieval is a heavy activity requiring fast tools to treat collections of significant size, and at the same time flexible tools to leave the most possible freedom during the experimentation. System X-IOTA was developed to answer the criterion of flexibility and thus to support fast installation of various experiments using automatic natural language treatments. The architecture is designed to allow a distribution of computations among distributed servers. We use this framework to test different set of weighting particularly the new Derivation from Randomness against Okapi.
