This paper presents a novel approach to Question Answering over structured data, which is based on Textual Entailment recognition. The main idea is that the QA problem can be recast as an entailment problem, where the text (T ) is the question and the hypothesis (H ) is a relational pattern, which is associated to “instructions” for retrieving the answer to the question. In this framework, give...

Many text planning systems are based on a theoretical linguistic approach which assumes the existence of relations between units of text. The relational approach most extensively used in text generation is the Rhetorical Structure Theory (rst, Mann and Thompson 1987). The phenomenon of multiple relations , i.e. the fact that in natural language texts we often nd more than one relation holding b...

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 experimente...

In Verbal Behavior (1957) B. F. Skinner identified and named five elementary verbal relations: mand, tact, intraverbal, textual and echoic. Because of their etymological commitment to visual and auditory stimuli respectively, the last two categories do not function well as general categories. Adding two more general categories, codic and duplic, to the first three results in a set of five mutua...

The NWO-programme Modelling textual organisation: coherence and cohesion studies the organisation of text into structural units by means of coherence (discourse relations between clausal and larger textual units) and cohesion (lexico-semantic relations between words in textual units). The programme is organised around two related PhD-projects, focussing on coherence and cohesion, respectively. ...

This paper presents a methodology for summarization from multiple documents which are about a specific topic. It is based on the specification and identification of the cross-document relations that occur among textual elements within those documents. Our methodology involves the specification of the topic-specific entities, the messages conveyed for the specific entities by certain textual ele...

Automatic indexing of video data, especially news videos, is in strong demand considering their contents' importance and value. Various attempts have been made to index news videos automatically in order to cope with this demand, including recent challenges that utilize accompanying textual information. However, most of these methods tend to be textual information driven, which do not thoroughl...

Intersemiotic translation, which can happen in the process of the translation of drama for theatre, can turn more complicated when the verbal sign system of drama has already undergone interlingual translation. The purpose of this study is to find the intersemiotic changes of translation from page to stage and to show the changes of indexical, iconic, and symbolic signs in the process of inters...
