Since collocations are blocks of meaning, they play an important role in natural language processing applications (word sense disambiguation, part of speech tagging, machine translation, etc). In this study, a corpus of Turkish is subjected to the following statistical techniques: frequency of occurrence, mutual information and hypothesis tests. We have utilized both stemmed and surface form of corpus to explore the effect of stemming in collocation extraction. The techniques are evaluated by recall and precision measures. Chi-square hypothesis test and mutual information methods have produced better results compared to other methods on Turkish corpus. In addition, we have found that a stemmed corpus facilitates discrimination between successful and unsuccessful collocation extraction methods. © 2010 Springer-Verlag Berlin Heidelberg.eninfo:eu-repo/semantics/closedAccessCollocationcollocation extractionCollocationcollocation extractionFrequency of occurrencesHypothesis testsMachine translationsMutual information methodMutual informationsNAtural language processingPart of speech taggingRecall and precisionStatistical techniquesTurkish textsTurkishsWord Sense DisambiguationComputational linguisticsInformation theorySpeech transmissionStatistical testsNatural language processing systemsConference Object10.1007/978-3-642-14770-8_272-s2.0-77956604153
