Radical

Radical Innovations

Aims

The main objective of the "Radical Innovations" project is to generate a better understanding of how “radical innovations” originate and contribute to the performance of companies. Automated content recognition in text (in patents, scientific publications and business news) yields an important set of indicators.

Partners

The project is carried out in collaboration with the Faculty of Business and Economics of K.U.Leuven ( Prof. Reinhilde Veugelers). LIIR is involved in the text mining aspects of the project.

Results

We have built software for document clustering that relies on probabilistic topic models. We have researched feature extraction and hierarchical classification of patents, which is a challenging task to perform automatically given the large amounts of classification codes (in the thousands) and the limited number of training examples.
