Discovering Entailment Relations Using "Textual Entailment Patterns"
نویسندگان
چکیده
In this work we investigate methods to enable the detection of a specific type of textual entailment (strict entailment), starting from the preliminary assumption that these relations are often clearly expressed in texts. Our method is a statistical approach based on what we call textual entailment patterns, prototypical sentences hiding entailment relations among two activities. We experimented the proposed method using the entailment relations of WordNet as test case and the web as corpus where to estimate the probabilities; obtained results will be shown.

TEG-REP: A corpus of Textual Entailment Graphs based on Relation Extraction Patterns
The task of relation extraction is to recognize and extract relations between entities or concepts in texts. Dependency parse trees have become a popular source for discovering extraction patterns, which encode the grammatical relations among the phrases that jointly express relation instances. State-of-the-art weakly supervised approaches to relation extraction typically extract thousands of u...
متن کاملNamed Entity Relation Mining using Wikipedia
Discovering relations among Named Entities (NEs) from large corpora is both a challenging, as well as useful task in the domain of Natural Language Processing, with applications in Information Retrieval (IR), Summarization (SUM), Question Answering (QA) and Textual Entailment (TE). The work we present resulted from the attempt to solve practical issues we were confronted with while building sys...
متن کاملTowards Conversation Entailment: An Empirical Investigation
While a significant amount of research has been devoted to textual entailment, automated entailment from conversational scripts has received less attention. To address this limitation, this paper investigates the problem of conversation entailment: automated inference of hypotheses from conversation scripts. We examine two levels of semantic representations: a basic representation based on synt...
متن کاملUsing Hypernymy Acquisition to Tackle (Part of) Textual Entailment
Within the task of Recognizing Textual Entailment, various existing work has proposed the idea that tackling specific subtypes of entailment could be more productive than taking a generic approach to entailment. In this paper we look at one such subtype, where the entailment involves hypernymy relations, often found in Question Answering tasks. We investigate current work on hypernymy acquisiti...
متن کاملExpanded Dependency Structure based Textual Entailment Recognition System of NTTDATA for NTCIR10-RITE2
This paper describes NTT DATA’s recognizing textual entailment(RTE) systems for NTCIR10 RITE2. We participate in four Japanese tasks, BC Subtask, Unit Test, Exam BC and Exam Search[5]. Our approach uses a ratio with the same semantic relations between words. It is necessary to recognize two semantic viewpoints, which are the semantic relation and the meaning between words in a sentence, in orde...
