Automated Text Summarization
As number of electronic documents increase rapidly, the need for techniques to analyze and interpret them emerges rapidly. Summaries can be considered as a concise representation of the underlying text. To form an ideal summary, full understanding of the document is essential. However this is difficult, if not impossible. Thus selecting important sentences from the original text and generating a cohesive text is a common technique in text summarization community. Cohesion structure of the text can be exploited to determine the importance of a sentence/phrase. Lexical chains is a useful and cheap tool to analyze cohesive structure in a text. In this talk, we will discuss our ongoing research on automated text summarization and keyphrase extraction using lexical chains. We will briefly define techniques to evaluate selected sentences.
