In chapter2,
section2.1, S. T. Park adopted 5 terms a query. However, a wider range of term
numbers in a query is adopted in this project: the length of LS from 3 to 15
versus the success rate is compared together while sentence rank, take first N
words in the selected sentence, from 3 to 15, even including stop words from
the top ranked sentences as a search query and remove the rest of them left in
the sentences. This procedure does not follow the traditional ways in text
retrieval, however, in chapter 5, the experiments show even better results when
the terms number are more than 10, compared to the same terms number in
traditional ways.
