Extractive Text Summarization Employing a Graph-Based Ranking System with Context Transfer
摘要
Text summarization has been an area of active research in the domain of natural language processing. Extractive text summarization focuses on highlighting the most essential parts of a document as its summary without any external additions to the original text. Conventional methods have focused on using sentence ranking algorithms like text rank, which uses position and similarity-based features to create graphs. However, the recent advent of deep learning, transfer learning, and context inclusion have been relatively undiscovered in this domain. This work proposes a graph-based ranking mechanism that uses relevant context to solve the task of extractive text summarization. Language modeling generates word representations that can provide a more comprehensive graph representation and achieve better results. The presented approach relies on graph-based ranking and the relevance and interpretation of each word in the document. The work is carried out on documents in the Marathi language with a standard-sized dataset. The proposed model has achieved a 75% F1 score and a Rouge L F1 score of 71%. The results obtained by the proposed system outperform those of state-of-the-art approaches. The system’s effectiveness is proved using the multiple performance metrics relevant to the text summarization task.
