Information Retrieval 1, Information Retrieval 2, Project Information Retrieval.
My current research ambitions concern two themes. One is autonomous search, where search engine algorithms discover their own features for ranking results, where they learn optimal combinations of such features for ranking, and where they are able to assess the quality of their results, all from interactions with users. The other is semantic search, where we try to improve retrieval algorithms by automatically discovering meaning in queries, documents, and user interactions with a search engine and online content.
