As the volume and diversity of documents grow, so do the size and complexity of the corresponding category hierarchies. To be able to access such hierarchically classified documents in real-time, we need fast automatic methods to navigate these hierarchies. Today\u2019s data domains are also very different from each other, such as medicine and politics. These distinct domains can be handled by different classifiers. A document representation system which incorporates the inherent category structure of the data should also add useful semantic content to the data vectors and thus lead to better separability of classes. In this paper, we present a scalable meta-classifier to tackle today\u2019s problem of multi-level data classification in the presence of large datasets. To speed up the classification process, we use a search-based method to detect the level-1 category of a test document. For this purpose, we use a category\u2013hierarchy-based vector representation. We evaluate the meta-classifier by scaling to both longer documents as well as to a larger category set and show it to be robust in both cases. We test the architecture of our meta-classifier using six different base classifiers (Random forest, C4.5, multilayer perceptron, na\u00efve Bayes, BayesNet (BN) and PART). We observe that even though there is a very small variation in the performance of different architectures, all of them perform much better than the corresponding single baseline classifiers. We conclude that there is substantial potential in this meta-classifier architecture, rather than the classifiers themselves, which successfully improves classification performance.<\/jats:p>","DOI":"10.1142\/s1469026815500200","type":"journal-article","created":{"date-parts":[[2015,12,24]],"date-time":"2015-12-24T03:47:18Z","timestamp":1450928838000},"page":"1550020","source":"Crossref","is-referenced-by-count":2,"title":["A Scalable Meta-Classifier Combining Search and Classification Techniques for Multi-Level Text Categorization"],"prefix":"10.1142","volume":"14","author":[{"given":"Nandita","family":"Tripathi","sequence":"first","affiliation":[{"name":"Department of Computing, Engineering and Technology University of Sunderland St Peters Way, Sunderland, SR6 0DD, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Oakes","sequence":"additional","affiliation":[{"name":"Research Institute of Information and Language Processing University of Wolverhampton MC Building, Stafford Street, Wolverhampton WV1 1LY, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Wermter","sequence":"additional","affiliation":[{"name":"Institute for Knowledge Technology Department of Computer Science University of Hamburg Vogt Koelln Str. 30, 22527 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2015,12,23]]},"reference":[{"key":"S1469026815500200BIB001","doi-asserted-by":"publisher","DOI":"10.1145\/1089815.1089821"},{"key":"S1469026815500200BIB002","doi-asserted-by":"publisher","DOI":"10.1007\/s10115-006-0013-y"},{"key":"S1469026815500200BIB004","doi-asserted-by":"publisher","DOI":"10.1023\/A:1009983522080"},{"key":"S1469026815500200BIB016","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijar.2008.11.006"},{"key":"S1469026815500200BIB019","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511809071"},{"key":"S1469026815500200BIB022","first-page":"187","volume-title":"Grouping Multidimensional Data: Recent Advances in Clustering","author":"Zeimpekis D.","year":"2005"},{"issue":"9","key":"S1469026815500200BIB024","first-page":"1232","volume":"22","author":"Ramasundaram S.","year":"2013","journal-title":"World Appl.
