Contextual Spellchecking Based on N-grams

Croatian Academic Spellchecker is an online web-service used for almost 20 years by thousands of users every day. In recent years, the service enabled rudimentary contextual spellchecking, based on pattern matching. In this paper we describe how it is possible to perform n-gram based contextual spellchecking of texts written in Croatian, regardless of the orthographic complexity of the Croatian language. Simple upgrade of the existing implementation was achieved by separating the system into several components. Using a well- known classifier, tweaking the frequency estimator and separating errors into confusion sets resulted in a contextual spellchecking system with a high score of F1 = 0.95 on the examined example.
