ITI extracts concepts from patent images

May 27, 2011

Patent searchers are searching using concepts to retrieve patents of interest. In many cases the concepts are described by complex patent images. ITI proposes a supervised machine learning-based approach to extract concepts from patent images combining visual and textual information. Read more here.. The approach and the results are to be presented at the Image Retrieval session of the IRF Symposium 2011 at Vienna.
