Exploiting Turkish Wikipedia as a semantic resource for text classification
Poyraz, Mitat; Ganiz, Murat Can; Akyokuş, Selim; Görener, Burak; Kilimci, Zeynep Hilal (IEEE, 2012)Majority of the existing text classification algorithms are based on the "bag of words" (BOW) approach, in which the documents are represented as weighted occurrence frequencies of individual terms. However, semantic ... -
Higher-order semantic smoothing for text classification
Poyraz, Mitat (Doğuş Üniversitesi Fen Bilimleri Enstitüsü, 2013-01)Text classification is the task of automatically sorting a set of documents into classes (or categories) from a predefined set. This task is of great practical importance given the massive volume of online text available ... -
Higher-order smoothing: a novel semantic smoothing method for text classification
Poyraz, Mitat; Kilimci, Zeynep Hilal; Ganiz, Murat Can (Science Press, 2014-05)It is known that latent semantic indexing (LSI) takes advantage of implicit higher-order (or latent) structure in the association of terms and documents. Higher-order relations in LSI capture "latent semantics". These ... -
Intelligent focused crawler: Learning which links to crawl
Taylan, Duygu; Poyraz, Mitat; Akyokuş, Selim; Ganiz, Murat Can (IEEE, 2011-06)A web crawler is defined as an automated program that methodically scans through Internet pages and downloads any page that can be reached via links. With the exponential growth of the Web, fetching information about a ... -
Metinsel veri madenciliği için anlamsal yarı-eğitimli algoritmaların geliştirilmesi
Ganiz, Murat Can; Altınel, Berna; Yaman, Utku; Çakırman, Erhan; Tutkan, Melike; Poyraz, Mitat; Kilimci, Zeynep Hilal; Tüysüzoğlu, Göksu; Engün, İsmail Murat (TÜBİTAK, 2015)Metinsel veri madenciliği büyük miktarlardaki metinsel verilerden faydalı bilgilerin çıkarılması veya bunların otomatik olarak organize edilmesini içerir. Büyük miktarlarda metinsel belgenin otomatik olarak organize ... -
A novel semantic smoothing method based on higher order paths for text classification
Poyraz, Mitat; Kilimci, Zeynep Hilal; Ganiz, Murat Can (IEEE, 2012-12-10)It has been shown that Latent Semantic Indexing (LSI) takes advantage of implicit higher-order (or latent) structure in the association of terms and documents. Higher-order relations in LSI capture "latent semantics". ...
