Short Text Classification Using Wikipedia Concept Based Document Representation

Short text classification is a difficult and challenging task in information retrieval systems since the text data is short, sparse and multidimensional. In this paper, we represent short text with Wikipedia concepts for classification. Short document text is mapped to Wikipedia concepts and the concepts are then used to represent document for text categorization. Traditional methods for classification such as SVM can be used to perform text categorization on the Wikipedia concept document representation. Experimental evaluation on real Google search snippets shows that our approach outperforms the traditional BOW method and gives good performance. Although it´s not better than the state-of-the-art classifier (see e.g. Phan et al. WWW ´08), our method can be easily implemented with low cost.
