An Evaluation of Adopting Language Model as the Checker of Preposition Usage
نویسندگان
چکیده
Many grammar checkers in rule-based approach do not handle errors that come from various usages, for example, the usages of prepositions. To study the behavior of prepositions, we introduce the language model into a grammarchecking task. A language model is trained from a large training corpus, which contains many short phrases. It can be used for detecting and correcting certain types of grammar errors, where local information is sufficient to make decision. We conduct several experiments on finding the correct English prepositions. The experiment results show that the accuracy of open test is 71% and the accuracy of closed test is 89%. The accuracy is 70% on TOEFL-level tests.

We address the task of automatically correcting preposition errors in learners’ Dutch by modelling preposition usage in native language. Specifically, we build two models exploiting a large corpus of Dutch. The first is a binary model for detecting whether a preposition should be used at all in a given position or not. The second is a multiclass model for selecting the appropriate preposition i...

This paper presents an algorithm for correcting language errors typical of second-language learners. We focus on preposition errors, which are very common among second-language learners but are not addressed well by current commercial grammar correctors and editing aids. The algorithm takes as input a sentence containing a preposition error (and possibly other errors as well), and outputs the c...

Software system verification is an efficient technique for ensuring the correctness of a software product, especially in safety-critical systems in which a small bug may have disastrous consequences. The goal of software verification is to ensure that the product fulfills the requirements. Studies show that the cost of finding and fixing errors in design time is less than finding and fixing the...
