Text Mining to Support Gene Ontology Curation and Vice Versa [chapter]

In this chapter, we explain how text mining can support the curation of molecular biology databases dealing with protein functions. We also show how curated data can play a disruptive role in the developments of text mining methods. We review a decade of efforts to improve the automatic assignment of Gene Ontology (GO) descriptors, the reference ontology for the characterization of genes and gene products. To illustrate the high potential of this approach, we compare the performances of an

We argue that automatic text categorization functions can ultimately be embedded into a Question-Answering (QA) system to answer questions related to protein functions. Because GO descriptors can be relatively long and specifi c, traditional QA systems cannot answer such questions. A new type of QA system, socalled Deep QA which uses machine learning methods trained with curated contents, is thus emerging. Finally, future advances of text mining instruments are directly dependent on the availability of highquality annotated contents at every curation step. Databases workfl ows must start recording explicitly all the data they curate and ideally also some of the data they do not curate.
