One of the major challenges in the most natural languages processing (NLP) tasks such as machine translation, text to speech and text mining is Word Sense Disambiguation (WSD). Supervised methods are the most common solutions for WSD. However, they need large tagged corpuses which are not available in some languages such as Persian. The Semi-Supervised methods can solve this problem by using small tagged corpus and large untagged corpus. This paper presents a coarsegrained work in WSD that uses
