Modal verbs express modality, and modality is concerned with the status of the proposition that describes an event, it also expresses the opinion and attitude of a speaker toward the proposition of an utterance. Since modalities are directly related to the objective world, subjective world, and language use, they have been a hot topic of philosophers, logicians and linguists. Philosophers concern with the relations between the objective world and the true/false values of the modality; logicians are interested in the relations among the possibility, necessity and the objective world; and linguists pay attention to the modality category, sense category, function, recognition, and application of modal verbs. In recent years, the linguistic studies of modal verbs have extended from general linguistic studies to computational linguistic studies. Since modal verbs are a complex semantic system and they are often indeterminate in senses, they have been a tough issue in linguistic studies and have attracted great attention. To clarify the status of the previous linguistic studies of modal verbs and reveal the characteristics of the studies will be of great significance for the further study. Therefore, this article will focus on the review of the previous linguistic studies of English modal verbs and the data mining of the characteristics of the previous studies, and based on the summary of the previous studies, give suggestions for the further study of the English modal verbs.

英语情态动词语言学研究综述与数据挖掘

情态动词表达情态，情态关系到描述事件的命题的状态，也表达说话人对话语命题的看法和态度。由于情态与客观世界、主观世界和语言使用直接相关，因此一直是哲学家、逻辑学家和语言学家的热门话题。哲学家关注客观世界与情态的真假价值之间的关系；逻辑学家对可能性、必然性和客观世界之间的关系感兴趣；语言学家关注情态动词的情态范畴、意义范畴、功能、识别和应用。近年来，情态动词的语言学研究已经从一般语言学研究扩展到计算语言学研究。由于情态动词是一个复杂的语义系统，其意义往往是不确定的，因此一直是语言学研究中的一个难题，引起了广泛的关注。弄清以往情态动词语言学研究的现状，揭示研究特点，对进一步研究具有重要意义。因此，本文将着重回顾前人对英语情态动词的语言学研究，并对前人研究的特点进行数据挖掘，并在总结前人研究成果的基础上，为进一步研究英语情态动词提出建议。动词。弄清以往情态动词语言学研究的现状，揭示研究特点，对进一步研究具有重要意义。因此，本文将着重回顾前人对英语情态动词的语言学研究，并对前人研究的特点进行数据挖掘，并在总结前人研究成果的基础上，为进一步研究英语情态动词提出建议。动词。弄清以往情态动词语言学研究的现状，揭示研究特点，对进一步研究具有重要意义。因此，本文将着重回顾前人对英语情态动词的语言学研究，并对前人研究的特点进行数据挖掘，并在总结前人研究成果的基础上，为进一步研究英语情态动词提出建议。动词。
