| Outline of Final Research Achievements |
Computational analyses have been carried out of the XML versions of Longman Dictionary of Contemporary English (3rd and 5th eds) with Jupyter Notebook, which is a state-of-the-art Python-programming environment for general data analysis. It has been found out that lexical descriptions in LDOCE are quite reliable linguistically and are based on fairly recent linguistic research. In particular, LDOCE's verb entries include systematic and explicit descriptions of syntactic frames in which the verbs appear for each of their meanings. This has led us to classify English verbs computationally using LDOCE after the fashion of Beth Levin (1993), where she classifies English verbs using diathesis alternations as a main criterion. Together with other analyses, it is demonstrated that computational analyses of dictionary data is essential for improving English vocabulary lists for educational purposes.
