A framework for classification and practice of verb tenses in English language.

Abstract

This work describes a framework developed for verb tenses classification in the English language and automatic generation of verb-tenses-oriented exercises, based on chosen texts for study. The classification is a rule-based process. The rules were analyzed and improved in the course of the work. This research brings a method for generation of exercises of transposition/transformation of verb tenses. By this method, it is possible to transpose each verb tense on a sentence to another verb tense, if there is an indexed example of that target verb tense. The verb tenses transposition method can also be applied in other contexts, like text generation, making it easy to choose an action and applying it to verb tense. Our results demonstrate that the framework is effective for its purpose, reaching 98.17% in average precision on the task of classifying verb tenses
