This paper provides a brief description of the system for recognizing textual entailment (RTE) Language Computer Corporation (LCC) used in the 2008 TAC RTE-4 Evaluation. Our RTE-4 work follows our previous work (Hickl and Bensley, 2007; Bensley and Hickl, 2008; Hickl, 2008) in using a pipeline of lightweight, largely statistical systems for commitment extraction, lexical alignment, and entailme...

This paper covers the recognition of textual entailment by means of different approaches based on lexical similarities and syntactic trees. These approaches are easily portable to other languages. We present the achieved results for each individual approach and we propose a simple voting strategy between these approaches and our previous system (presented in Second PASCAL Recognising Textual En...

Systems designed to recognize textual entailment typically employ both syntax and semantics. Our goal in this paper is to explore the degree to which semantics alone can be used to accurately detect entailment so that we can gain a better understanding of this single component within an entailment system. This paper reports the knowledge-bases considered and selected for person names, locations...

Most Web-based Q/A systems work by finding pages that contain an explicit answer to a question. These systems are helpless if the answer has to be inferred from multiple sentences, possibly on different pages. To solve this problem, we introduce the HOLMES system, which utilizes textual inference (TI) over tuples extracted from text. Whereas previous work on TI (e.g., the literature on textual ...

In the logic approach to Recognizing Textual Entailment, identifying phrase-tophrase semantic relations is still an unsolved problem. Resources such as the Paraphrase Database offer limited coverage despite their large size whereas unsupervised distributional models of meaning often fail to recognize phrasal entailments. We propose to map phrases to their visual denotations and compare their me...

This study aimed to explore the function and frequency of textual metadiscourse markers (MDMs) in scientific English and Persian texts. Based on the qualitative and quantitative analysis of textual markers characterizing the selected genre, four different textbooks, two written in English and two in Persian were analyzed to identify the textual metadiscourse categories (including logical marker...

The present study sets out to investigate whether the position of literary works in the English literary polysystem influences the Iranian translators’ translational behavior at the textual level. Given the prominent position of canon and bestseller novels in English literary polysystem, the study intends to find out whether the translators of canon and bestseller novels are faithful to theirso...
