Text summarization is the process of converting a huge text file into a summarized version preserving its meaning and context. The major aspect of any extractive text summarization technique is to provide precise and accurate summary by using any sentence ranking algorithms. The text is first tokenized and preprocessed. The sentences in the text are ranked according to the corresponding graph based ranking algorithm and finally the top K-scored sentences are included in the summary. Combining the graph based ranking algorithm along with mean shift clustering enables us to efficiently summarize the articles increasing the precision of the system generated summary and also reduces the execution time. The efficiency of these approaches are evaluated using rouge metrics and execution time.
