The Difference of Word Importance before and after Bookmark for Novel Abstract in Each Reading Progress

Abstract This paper describes an index and target periods to generate a novel abstract for each reading progress. As reading a long novel, the reading is often interrupted as putting a bookmark into the book. Sometimes, the information described in the read part is forgotten away from the reader’s memory. Then the abstract for each reading progress is effective to remind the reader of the story. The goal of this study is to automatically generate the abstract for each reading progress. In this paper, the difference of the word importance before and after bookmark is considered as the index to select the sentences for the abstract. Also, from where the sentences should be selected is compared as discussing the output results. Through the experiment, it was confirmed that the abstract in which the sentences were selected from the period just before the bookmark was better than the abstract generated from all part of the past story. Moreover, it was suggested that not paragraphs but sentences might be appropriate unit to generate the abstract for each reading progress.
