Item EXTRACTIVE TEXT SUMMARIZATION FOR TURKISH USING TF-IDF AND PAGERANK ALGORITHMS(2022-02-15) Akülker, Emre; Turhan, ÇiğdemThe improvements on the information technologies and the Internet infrastructure have enabled the users to reach information in an easier and faster manner. However, another consequence of the improvements is the information overload. To reach the required information about a specific topic has become more difficult day by day. Automatic text summarization helps to solve the problem by minimizing the document size while keeping its core information required by the user. This thesis presents an extractive single document automatic text summarization system for Turkish, which implements the statistical-based TF-IDF algorithm as well as a hybrid approach which is a combination of TF-IDF with the graph-based PageRank algorithm. The study aims to reveal the usability and the effectiveness of these algorithms for Turkish documents. Moreover, TF-IDF and TF-IDF with PageRank (Hybrid) systems have been evaluated and compared with each other using the co-selection evaluation techniques precision, recall and F-score.
