AandP: Utilizing Prolog for converting between active sentence and passive sentence with three-steps conversion
This addresses a specific aspect of English grammar for computational linguistics, but it is incremental as it applies existing tools to a known problem.
The paper tackles the problem of converting between active and passive sentences in English grammar by developing a method using Prolog and Definite Clause Grammars, handling cases like 12 tenses, modal verbs, and negative forms, with source code provided.
I introduce a simple but efficient method to solve one of the critical aspects of English grammar which is the relationship between active sentence and passive sentence. In fact, an active sentence and its corresponding passive sentence express the same meaning, but their structure is different. I utilized Prolog [4] along with Definite Clause Grammars (DCG) [5] for doing the conversion between active sentence and passive sentence. Some advanced techniques were also used such as Extra Arguments, Extra Goals, Lexicon, etc. I tried to solve a variety of cases of active and passive sentences such as 12 English tenses, modal verbs, negative form, etc. More details and my contributions will be presented in the following sections.
