e of have (got) to
The previous chapters have introduced the process of word sense disambiguation and its model construction process. Also, there are some major findings of word sense disambiguation model and its extracted rules. On the basis of the previous research content, this chapter will focus on the studies of sense gradience of have (got) to, which is a natural language phenomenon in the corpora annotation periods.
7.1 Introduction of sense gradience of have (got) to
According to Leech and Coates (1980), the calssification of gradience are divided into five classes, including natural law, ethical/moral, reasonableness, regulation, personal authority. This study adopts their studies and applies the five gradiences to research the different syntactic features under different gradience.Figure 7.1 shows that the restriction gradience strengthens with the arrow directions from left to right. The natural law has the lowest human intervenes and human constraints. It is quite acceptable for people of sentences refer to the ethical code and social conventions. The reasonableness represents the much lower restriction gradience meaning. Also the regulations made by companies, court, and schools have a more constraint in the modal verbs gradience meaning. The personal authority has the highest human imposition, and the human constraint is absolutely direct and clear. Thus, this model is reasonable and can be testified by the data.

Conclusion
This chapter is the last part and conclusion fragment of this paper. This part will introduce the major findings, implications for this research and the limitations and suggestions for the further studies.This study mainly focuses on the word sense disambiguation of quasi-modal verbs have (got) to. Based on the word sense disambiguation, the word sense gradience has been acquired in this research, which is the pioneer work in the quasi-modal verbs` study. The major findings are as follows: Firstly, the research content of the quasi-modals? word sense disambiguation is the innovative studies in the modality researches. The previous modal verbs? studies mainly focus on the first or secondary modal verbs. The studies about quasi-modals haven`t been inquired. Based on the formal concept analysis theory and the APOSD tools, this research constructs the word sense disambiguation model of quasi-modal verbs have (got) to in view of the self-built corpus. The WSD model of quasi-modal verbs have (got) to has been established and the accuracy of the WSD reaching the 91.5% in training set and 81.3% in testing set. Secondly, th
