This chapter is based on the framework of educational data mining (EDM). It focuses on the relationship between essay topics and co-occurrence patterns of learners' grammatical errors. The techniques of data mining shed light on learners' hidden association pattern of grammatical errors. Investigating learners' grammatical errors is a very important area in language teaching. In the past, this research was conducted only in the area of language teaching. However, in recent years, it has been conducted in the field of natural language processing such as the research on automated scoring of learners' writing or speaking and automated grammatical error detection. The subject 'English writing' was introduced to Japanese high schools after the curriculum was revised in 1989. Error analysis (EA) has been conducted since the 1950s because learners' errors can be considered as a benchmark for the proficiency in a language.
