Text mining has been used for various purposes, such as document classification and extraction of domain-specific information from text. In this paper we present a study in which text mining methodology and algorithms were properly employed for academic dishonesty (cheating) detection and evaluation on open-ended college exams, based on document classification techniques. Firstly, we propose tw...

This paper presents a thesaurus-based approach to document classification. We define a classification space based on the notion of theme vectors. For a new text, we compute its characteristic vector by considering only a sample of randomly extracted lemmas. Then, we compute the differences between this vector and the vectors in the document model and the classification of the new text is decide...
