How it works

This Topic Detection API is based on a patented algorithm developed by Proxem and presented in 2013 for the main French Natural Language Processing annual conference. The published paper’s title is “Cross-lingual and generic text categorization”.

About the paper
Text categorization usually requires a significant investment, which must often be associated to a field adaptation. The approach we propose here allows to finely associate a graph of Wikipedia categories to any text written in a given language. Moreover, the interlingual index of the online encyclopedia allows to get a subset of this graph in most other languages.
