WikiGames : une plateforme de jeux dédiée à la validation d’une base de connaissances produite à partir de techniques d’extraction d’information ouverte
Open information extraction techniques can generate a large amount of relation triplets from unstructured corpus of texts. These large collections of triplets often contain a good portion of noisy triplets that brings little to no usable information. These collections of triplets can become too large to be manually validated by most small teams in a reasonable amount of time and hiring the number of validators required for such task would be too costly for most teams. The use of games as a crowdsourcing tool has shown great success in acquiring a large pool of volunteer for the realization of similar tasks. We have therefore looked into the extraction of a set of useful knowledge from a rather large and noisy relation triplets collection that was previously extracted using an open information extraction tool. We have then started the process of validating the resulting knowledge base with the help of a games with a purpose platform.
