In our Knowledge Mining Laboratory, we specialize in developing methods for extracting useful information from patent documents, as well as information available in social networking sites such as twitter or online forums. In addition, we collaborate with industry and factory data for the introduction of machine learning. For the patents, for example, a team develops methods to rate the usefulness of the patented technology from their documents, mapping out the relevance of certain technologies when used by others, etc. As for social network analyses, we focus on information that can help market analysis, such as customer behavior.
