Some pattern examples are the following: We also removed questions that showed statistical values outside of convenient ranges: the number of answers, length of the longest answer and length of the sum of all answers (both absolute and normalized) were taken in consideration.
we discarded questions with the following characteristics: • there were less than three answers 8 • the longest answer was over 400 words (likely a copy-and-paste) • the sum of the length of all answers outside of the (100, 1000) words interval • the average length of answers was outside of the (50, 300) words interval At this point a second version of the dataset was created to evaluate the summarization performance under scoring function (6) and 7; it was generated by manually selecting questions that arouse subjective, human interest from the previous 89,814 question-answer pairs.
