Abstract

This paper describes the design of online textual presentation tool developed by using various approaches like information retrieval, information extraction, topic identification and sentence weightage algorithms. To design a presentation for the given user query, the following approaches are used: Information extraction based on Boolean and probabilistic approaches, Topic identification based on semantic based approach, Sentence weightage algorithm based on importance of the terms and topics involved in the documents. A combination of these approaches led to the design of PowerPoint presentation file.
