Abstract：Word, as the smallest semantic unit, has complex relationship with text domains. Especially, it is often difficult to define the exact domain for the commonly used words. In fact, it is not always necessary to establish clear relationship between the word and the domain for real applications. Instead, we can achieve satisfactory results by quantifying the domain property of the words. In this paper, we propose an unsupervised method for quantifying the domain property of words, based on word association information in the large-scale corpus. We valide the proposed value of words domain property by comparing against the classical TF * IDF measure in the topic detection application.
