Multi-document Summarization Based on Sentence Features and Frequent Itemsets

Information retrieval is the process of searching for information and related knowledge within the collected documents or from the web Users and are presented with vast information which suffers from redundancy and irrelevance. Searching for the required information from this huge collection is a tiresome task. This motivated the researchers to provide high quality summary that allows the user to quickly locate the desired information. In this paper an attempt is made to improve the performance of summarization technique using the sentence features as length, position, centriod, Noun and by adding the new feature Noun-Verb pair. The second technique exploits modified FIS – Frequent Itemset Sequence generation algorithm for summarization. The redundancy elimination techniques are applied to achieve the efficient summary from various documents. The performance of proposed algorithms is compared with the existing MEAD summarization technique by considering F-measure. Introduction of Noun –Verb pair improves the quality of summarization compared to existing MEAD and our proposed FIS technique.
