Automated keyword extraction is essential as the daily text data to be reached and processed have increased tremendously over the Internet, e.g. millions of news articles are published daily online. In this paper, a novel ensemble model for automatic extraction of keywords from news articles is proposed. The proposed model handles keyword extraction as a sequence labeling task. Two sub-modules representing the statistical and graphical features by their calculated scores for each input token were combined in the token classification module. The Ensemble Token Classification module was trained and tested separately with the ensemble algorithms Random Forest, XgBoost, Decision Tree and Voting Classification. For training, we collected two news datasets from Kazakh and Russian news sites published in Cyrillic alphabet. We also collected an Arabic news dataset, ArabianNews. The performance of the model was also compared with the widely used 500N-KPCrowd dataset in the literature, which consists of English news content in Latin alphabet. The proposed model achieved the best performance with an [Formula: see text]-score of 0.71 and 0.86 on the 500N-KPCrowd and Russian datasets, respectively. We attained the best [Formula: see text]-score (0.97) with the KazakhNews and ArabianNews datasets. <\/jats:p>","DOI":"10.1142\/s0218194024500128","type":"journal-article","created":{"date-parts":[[2024,3,22]],"date-time":"2024-03-22T09:50:36Z","timestamp":1711101036000},"page":"1047-1061","source":"Crossref","is-referenced-by-count":4,"title":["An Ensemble Keyword Extraction Model for News Texts with Statistical and Graphical Features"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2449-2540","authenticated-orcid":false,"given":"Aiman","family":"Abibullayeva","sequence":"first","affiliation":[{"name":"Computer Engineering Department, Faculty of Engineering, Akhmet Yassawi University, Turkistan, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2114-1289","authenticated-orcid":false,"given":"H\u00fcma","family":"K\u0131l\u0131\u00e7","sequence":"additional","affiliation":[{"name":"Computer Engineering Department, Faculty of Technology, Gazi University, Ankara 06500, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8669-823X","authenticated-orcid":false,"given":"Aydin","family":"Cetin","sequence":"additional","affiliation":[{"name":"Computer Engineering Department, Faculty of Technology, Gazi University, Ankara 06500, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2024,5,22]]},"reference":[{"key":"S0218194024500128BIB002","first-page":"175","volume-title":"Proc. 26th Conf.
