Mental health information Web search and semantic search extension

MentalWatch is a medical search engine that applies concepts from information retrieval and Web 2.0 to enable patients and doctors to better understand mental illnesses. It puts together scientific articles, news, blog posts and other kinds of contents related to mental health from several Web sources. The main contribution of this work is a software architecture and a semantic search model providing semantic capabilities such as further search suggestions that take advantage of specific domain knowledge. This paper presents an evaluation of the platform taking into account typical information retrieval showing that the results are better than those provided by a general purpose search engine.
