Takahiko Suzuki, Miyata Koki, Sachio Hirokawa · 2016
When learning a new word in language learning, there are two problems. One is how difficult the word itself is. The second is, in what kind of situation, it will be used. There is a research that defined quantitative ambiguity of words based on the structure of WordNet, then investigated the relationship between the ambiguity and the difficulty level of words. In this paper, we re-define ambiguity of word occurrences in text by using the result of word sense disambiguation technique. We analyze the relationship between the ambiguity of words and their difficulty level. We compare the result with those in the previous research. Utilizing knowledge and training data affect the relationship between the difficulty and ambiguity of words.
