Extractive Based Automatic Text Summarization

Automatic text summarization is the process of reducing the text content and retaining the important points of the document. Generally, there are two approaches for automatic text summarization: Extractive and Abstractive. The process of extractive based text summarization can be divided into two phases: pre-processing and processing. In this paper, we discuss some of the extractive based text summarization approaches used by researchers. We also provide the features for extractive based text summarization process. We also present the available linguistic preprocessing tools with their features, which are used for automatic text summarization. The tools and parameters useful for evaluating the generated summary are also discussed in this paper. Moreover, we explain our proposed lexical chain analysis approach, with sample generated lexical chains, for extractive based automatic text summarization. We also provide the evaluation results of our system generated summary. The proposed lexical chain analysis approach can be used to solve different text mining problems like topic classification, sentiment analysis, and summarization.
