User Profile Identification Based on Text Mining

Various scientific disciplines at the University of West Bohemia in Pilsen attract researchers in various fields of specialty. Because of numerous locations of University buildings combined with overlapping focus of faculties, it is often the case that people of the same interest, working at one institution, do not know each other, which impedes sharing of their experience. It is our objective to merge experts based on similarity of their user profiles. Another objective is to utilize user profiles to find additional documents that may be of interest of a user. Packet filtering approach is used to collect information on users. User profiles are generated with the aid of Suffix Tree Clustering algorithm on the basis of characteristic phrases.
