In this paper, two improved algorithms for extracting and discovering topic words are proposed in the Rapid Topic word Detection (RTD) Algorithm and CategoryTextRank (CTextRank) Algorithm, which can effectively obtain information by extracting and filtering the topic words in the text. The algorithms overcome the shortcomings of traditional topic words discovering algorithms that require deep linguistic knowledge, domain or language specific annotated corpora. The two algorithms we proposed can process both short and long text. The biggest advantage of the algorithms is that they are unsupervised machine learning algorithms. They need not be trained to process text directly to get topic words. The Accuracy rate, recall rate and F-measure index have been greatly improved when using the two algorithms which show that the results obtained compare favorably with previously published results on datasets Inspec and SemEval. The first algorithm Rapid Topicword Detection improves the metrics compared to PositionRank and TextRank, the second algorithm CategoryTextRank improves the metrics compared to TextRank, SingleRank and TF-IDF.<\/jats:p>","DOI":"10.1142\/s0218194020400173","type":"journal-article","created":{"date-parts":[[2020,10,15]],"date-time":"2020-10-15T09:52:14Z","timestamp":1602755534000},"page":"1097-1118","source":"Crossref","is-referenced-by-count":0,"title":["Two Improved Topic Word Detection Algorithms"],"prefix":"10.1142","volume":"30","author":[{"given":"Zehao","family":"Yu","sequence":"first","affiliation":[{"name":"School of Computer Science, Beijing University of Posts and Telecommunications, Beijing 100876, P.
