Previous work on automatic construction of taxonomies from text documents either ignored temporal information or used fixed time periods to discretize the time series of documents. In this paper, we propose a time-aware method to automatically construct and effectively maintain a taxonomy from a given series of documents preclustered for a domain of interest. The method extracts temporal information from the documents and uses a timestamp contribution function to score the temporal relevance of the evidence from source texts when identifying the taxonomic relations for constructing the taxonomy. Experimental results show that our proposed method outperforms the state-of-the-art methods by increasing F-measure up to 7%\u201320%. Furthermore, the proposed method can incrementally update the taxonomy by adding fresh relations from new data and removing outdated relations using an information decay function. It thus avoids rebuilding the whole taxonomy from scratch for every update and keeps the taxonomy effectively up-to-date in order to track the latest information trends in the rapidly evolving domain. <\/jats:p>","DOI":"10.1162\/tacl_a_00117","type":"journal-article","created":{"date-parts":[[2018,12,28]],"date-time":"2018-12-28T15:44:07Z","timestamp":1546011847000},"page":"551-564","source":"Crossref","is-referenced-by-count":1,"title":["Utilizing Temporal Information for Taxonomy                     Construction"],"prefix":"10.1162","volume":"4","author":[{"given":"Luu Anh","family":"Tuan","sequence":"first","affiliation":[{"name":"Institute for Infocomm Research, Singapore,"}]},{"given":"Siu Cheung","family":"Hui","sequence":"additional","affiliation":[{"name":"School of Computer Engineering, Nanyang Technological University,                         Singapore,"}]},{"given":"See Kiong","family":"Ng","sequence":"additional","affiliation":[{"name":"Institute of Data Science, National University of Singapore,"}]}],"member":"281","reference":[{"key":"p_4","doi-asserted-by":"crossref","first-page":"233","DOI":"10.6028\/jres.071B.032","volume":"71","author":"Edmonds Jack","year":"1967","journal-title":"Journal of Research of the National Bureau of Standards B"},{"issue":"2","key":"p_6","doi-asserted-by":"crossref","first-page":"395","DOI":"10.1007\/s10115-010-0370-4","volume":"28","author":"Fodeh Samah","year":"2011","journal-title":"Knowledge and Information Systems"},{"issue":"3","key":"p_7","doi-asserted-by":"crossref","first-page":"231","DOI":"10.1017\/S1351324903003176","volume":"9","author":"Harabagiu Sanda M.","year":"2003","journal-title":"Natural Language Engineering"},{"issue":"11","key":"p_16","doi-asserted-by":"crossref","first-page":"39","DOI":"10.1145\/219717.219748","volume":"38","author":"Miller George A.","year":"1995","journal-title":"Communications of the ACM"}],"container-title":["Transactions of the Association for Computational Linguistics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mitpressjournals.org\/doi\/pdf\/10.1162\/tacl_a_00117","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,12]],"date-time":"2021-03-12T21:38:32Z","timestamp":1615585112000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/tacl\/article\/43377"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,12]]},"references-count":4,"alternative-id":["10.1162\/tacl_a_00117"],"URL":"https:\/\/doi.org\/10.1162\/tacl_a_00117","relation":{},"ISSN":["2307-387X"],"issn-type":[{"value":"2307-387X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,12]]}}}
