Document Summarization using Wikipedia

Document Summarization using Wikipedia by Krishnan Ramanathan, Yogesh Sankarasubramaniam, Nidhi Mathur, and Ajay Gupta is a recent HP Technical Report. It seems the small screens used by mobile devices are creating a demand for document summarization.
Although most of the developing world is likely to first access the Internet through mobile phones, mobile devices are constrained by screen space, bandwidth and limited attention span. Single document summarization techniques have the potential to simplify information consumption on mobile phones by presenting only the most relevant information contained in the document. In this paper we present a language independent single-document summarization method. We map document sentences to semantic concepts in Wikipedia and select sentences for the summary based on the frequency of the mapped-to concepts. Our evaluation on English documents using the ROUGE package indicates our summarization method is competitive with the state of the art in single document summarization.
