Abstract: 

A tremendous amount of text-content is available in the form of documents, microblogs, scientific articles, etc. and this is keep on growing exponentially over the time with the arrival of new data from multiple sources. In order to scan through such large volume of data, there is a requirement of developing some efficient text-mining techniques. Summarization techniques become popular in extracting relevant information from huge amount of data. Moreover development of some supervised technique requires huge amount of labeled data. The annotation of data for developing supervised information extraction systems is time-consuming and costly. In summarization, the aim is to generate compress, relevant, and concise information from the available data. Different facets of summarization, like document summarization, figure-summarization, microblog summarization, and multi-modal microblog summarization, will be discussed in the talk.

The task of summarization is posed as multiobjective optimization problem where multiple quality measures like cohesion, readability, anti-redundancy, are simultaneously optimized. In order to measure these quality measures, different semantic similarity measures, textual entailment concepts are utilized. Techniques like differential evolution are used as the underlying optimization strategy. Some new genetic operators inspired by the concepts of self-organizing map are also incorporated in the optimization process. Extensive experimentations have verified that all our proposed methods outperform many other state-of-the-art methods when tested on task-related data-sets.
