Correcting Ambiguous Japanese Sentences Based on Japanese Dependency Analysis

The purpose of this study is to correct ambiguous Japanese sentences into clear and understandable ones. Ambiguous sentences are ones that can be interpreted differently by different readers. To achieve this purpose, existing studies have corrected ambiguous sentences by replacing word order and inserting commas using word occurrence probabilistic models. However, such probabilistic models often produce sentences that do not reflect the writer's intention because they prioritize frequently used sentence patterns over sentence meanings. As a result, the corrected sentences can be clearly written but missing points. To solve the problem, this study proposes a new method which replaces the word order in a sentence focusing on the semantic connection between words and inserts commas, resulting in producing clear sentences without losing the writer's intention.
