Semantic and Logical Inference Model for Textual Entailment

چکیده

We compare two approaches to the problem of Textual Entailment: SLIM, a compositional approach modeling the task based on identifying relations in the entailment pair, and BoLI, a lexical matching algorithm. SLIM’s framework incorporates a range of resources that solve local entailment problems. A search-based inference procedure unifies these resources, permitting them to interact flexibly. BoLI uses WordNet and other lexical similarity resources to detect correspondence between related words in the Hypothesis and the Text. In this paper we describe both systems in some detail and evaluate their performance on the 3rd PASCAL RTE Challenge. While the lexical method outperforms the relation-based approach, we argue that the relation-based model offers better long-term prospects for entailment recognition.

Efficient Logical Inference for Semantic Processing

Dependency-based Compositional Semantics (DCS) provides a precise and expressive way to model semantics of natural language queries on relational databases, by simple dependency-like trees. Recently abstract denotation is proposed to enable generic logical inference on DCS. In this paper, we discuss some other possibilities to equip DCS with logical inference, and we discuss further on how logi...

A Logic-Based Semantic Approach to Recognizing Textual Entailment

This paper proposes a knowledge representation model and a logic proving setting with axioms on demand successfully used for recognizing textual entailments. It also details a lexical inference system which boosts the performance of the deep semantic oriented approach on the RTE data. The linear combination of two slightly different logical systems with the third lexical inference system achiev...

A Logic-based Approach for Recognizing Textual Entailment Supported by Ontological Background Knowledge

We present the architecture and the evaluation of a new system for recognizing textual entailment (RTE). In RTE we want to identify automatically the type of a logical relation between two input texts. In particular, we are interested in proving the existence of an entailment between them. We conceive our system as a modular environment allowing for a high-coverage syntactic and semantic text a...

Bag-of-words methods to the problems of semantic text classification and textual entailment have seen some successful applications [3], their straightforward applications are known to break when the training data is sparse, the number of classes is large, or classes do not have clear syntactic boundaries (for example when negational, conditional sentence markers significantly affect classificat...
