It has a significant compression ratio in comparison with those of state-of-the-art methods on the same dataset. Given a text, first, the proposed method splits it into<jats:italic>n<\/jats:italic>-grams and then encodes them based on<jats:italic>n<\/jats:italic>-gram dictionaries. In the encoding phase, we use a sliding window with a size that ranges from bigram to five grams to obtain the best encoding stream. Each<jats:italic>n<\/jats:italic>-gram is encoded by two to four bytes accordingly based on its corresponding<jats:italic>n<\/jats:italic>-gram dictionary. We collected 2.5\u2009GB text corpus from some Vietnamese news agencies to build<jats:italic>n<\/jats:italic>-gram dictionaries from unigram to five grams and achieve dictionaries with a size of 12\u2009GB in total. In order to evaluate our method, we collected a testing set of 10 different text files with different sizes. The experimental results indicate that our method achieves compression ratio around 90% and outperforms state-of-the-art methods.<\/jats:p>","DOI":"10.1155\/2016\/9483646","type":"journal-article","created":{"date-parts":[[2016,11,14]],"date-time":"2016-11-14T16:04:31Z","timestamp":1479139471000},"page":"1-11","source":"Crossref","is-referenced-by-count":17,"title":["<i>n<\/i>-Gram-Based Text Compression"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1604-9066","authenticated-orcid":true,"given":"Vu H.","family":"Nguyen","sequence":"first","affiliation":[{"name":"Faculty of Information Technology, Ton Duc Thang University, Ho Chi Minh City, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8940-3778","authenticated-orcid":true,"given":"Hien T.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Ton Duc Thang University, Ho Chi Minh City, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hieu N.","family":"Duong","sequence":"additional","affiliation":[{"name":"Faculty of Computer Science and Engineering, Ho Chi Minh City University of Technology, Ho Chi Minh City, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vaclav","family":"Snasel","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, VSB-Technical University of Ostrava, Ostrava, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"19","year":"2010"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/proc.1967.5493"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1002\/j.1538-7305.1948.tb01338.x"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/jrproc.1952.273898"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/5.286189"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1145\/214762.214771"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/mc.1984.1659158"},{"issue":"3","key":"24","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1109\/TIT.1977.1055714","volume":"23","year":"1977","journal-title":"IEEE Transactions on Information Theory"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1109\/tit.1978.1055934"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/tcom.1984.1096090"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-31277-4_26"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.camwa.2007.05.014"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.csi.2014.05.005"},{"issue":"1","key":"1","first-page":"66","volume":"8","year":"2011","journal-title":"The International Arab Journal of Information Technology"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/j.aei.2008.05.001"},{"key":"10","year":"2009"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1145\/322344.322346"}],"container-title":["Computational Intelligence and Neuroscience"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2016\/9483646.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2016\/9483646.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2016\/9483646.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,24]],"date-time":"2017-06-24T23:33:57Z","timestamp":1498347237000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/cin\/2016\/9483646\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":17,"alternative-id":["9483646","9483646"],"URL":"https:\/\/doi.org\/10.1155\/2016\/9483646","relation":{},"ISSN":["1687-5265","1687-5273"],"issn-type":[{"value":"1687-5265","type":"print"},{"value":"1687-5273","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016]]}}}
