IMTKU Textual Entailment System for Recognizing Inference in Text at NTCIR-11 RITE-VAL
In this paper, we describe the IMTKU (Information Management at TamKang University) textual entailment system for recognizing inference in text at NTCIR-11 RITE-VAL (Recognizing Inference in Text). We proposed a textual entailment system using statistics approach that integrate semantic features and machine learning techniques for recognizing inference in text at NTCIR-11 RITEVAL task. We submi...
متن کاملNAK Team's System for Recognizing Textual Entailment at the NTCIR-11 RITE-VAL Task
The NAK team participated in the NTCIR-11 RITE-VAL task. This paper describes our textual entailment system and discusses the official results. Our system adopts statistical method: classification of the support vector machine (SVM). For Japanese SV subtask, our best result was 63.19 for macro-F1 score and 74.55 for accuracy. For Japanese FV subtask, our best result was 53.07 for macro-F1 score...
متن کاملExperiments for NTCIR-11 RITE-VAL Task at Shibaura Institute of Technology
This paper reports the evaluation results of our textual entailment system at NTCIR-11 RITE-VAL task. We participated in the Japanese System Validation (SV) and Fact Validation (FV) subtasks. In our system, the meaning of a text is represented as a set of dependency triples consisting of two words and their relation. Comparing two sets of dependency triples with respect to conceptual similarity...
متن کاملIII&CYUT Chinese Textual Entailment Recognition System for NTCIR-11 RITE-VAL
Textual Entailment (TE) is a critical issue in natural language processing (NLP). In this paper, we report how our hybrid approach system works in NTCIR-11 RITE-VAL task [15]. We attended both Fact Validation (FV) and System Validation (SV) subtasks for Chinese. In the SV subtask, we also attended both binary classification (BC) and multi-classification (MC). For the SV BC subtask, our system d...
متن کاملDescription of the NTOU RITE-VAL System at NTCIR-11
System validation subtask in NTCIR aims at developing techniques to deal with many kinds of language phenomena about textual entailment. This paper introduces our system participating in NTCIR-11 RITE-VAL SV Subtask. By adopting different combination of features related to WordNet, Tongyici Cilin, and syntactic information, 5 SV-BC and 5 SV-MC formal runs were submitted. The best BC run achieve...
