The key feature makes it differ from other similiar projects is that some possible complex PTT article patterns are considered (e.g. signature files (簽名檔), edited articles) and some algorithms are applied to deal with important values that are missing in sources (e.g. exact time and date of comments), so that a better data quality can be guaranteed.
