Exploring the Partial Textual Entailment Problem for Bengali News Texts

Abstract

Formal definition textual entailment implies strict meaning relationship of meaning in its totality between text (T) and hypothesis (H). Even if the text have main ideas of a hypothesis, but lacks minor information or have additional information then treated as an entirely unrelated text. In these cases we are left with no sense of how close (T, H) were to entailment. In various applications of entailment, major attention has given on strict entailment only. However, in reality strict entailment cases are relatively lower in compared to partial entailment cases, are prevalent. We introduce the idea of partial entailment in this paper and defining it empirically. We have developed corpus and finally proposed baseline architecture for automatic identification of partial textual entailment. This work is on Bengali news texts.
