Recognition of textual entailment is not an easy task. In fact, early experimental evidences in [1] seems to demonstrate that even human judges often fail in reaching an agreement on the existence of entailment relation between two expressions. We aim to contribute to the theoretical and practical setting of textual entailment, through both a linguistic inspection of the textual entailment phen...

This paper describes our work in NTCIR-11 on RITE-3 Binary-class (BC) subtask and Multi-class (MC) subtask in Simplified Chinese. We proposed a textual entailment system using a hybrid approach that integrates many features. The performance of the proposed method in the formal run achieved Macro-F1’s of 59.71% in BC subtask and only 23.19% in MC subtask

Over the years, various meta-languages have been used to manually enrich documents with conceptual knowledge of some kind. Examples include keyword assignment to citations or, more recently, tags to websites. In this paper we propose generative concept models as an extension to query modeling within the language modeling framework, which leverages these conceptual annotations to improve retriev...

This study aimed to investigate the impact of textual enhancement and metalinguistic explanation as focus-on-form tasks tending to encourage the acquisition of nominal clauses (NCs) in English. It explored (a) whether textual enhancement and metalinguistic explanation would promote and enhance the knowledge of NCs, (b) whether these two tasks would differ in terms of enhancing learners' knowled...

We consider the problem of personalized text-based music retrieval where users’ history of preferences are taken into account in addition to their issued textual queries. Current retrieval methods mostly rely on songs meta-data. This limits the query vocabulary. Moreover, it is very costly to gather this information in large collections of music. Alternatively, we use music annotations retrieve...

We report our experience of using Triple Graph Grammars (TGG) to synchronize models of the rich and complex Architecture Analysis and Design Language (AADL), an aerospace standard of the Society of Automotive Engineers. A synchronization layer has been developed between the OSATE (Open Source AADL Tool Environment) textual editor and the Adele graphical editor in order to improve their integrat...

Concept Definitions First we present the abstract construct definitions that were used for the SDL2000 meta-model. There are different levels of abstractions. Some constructs are so general that they are used in virtually every object-oriented language, others are more specific and may only be reused among related languages or only within one language. Figure 3.9 shows the abstract structure co...

Meta-models are a prerequisite for model-driven engineering (MDE) in general and consequently for model-driven web engineering in particular. Various modelling languages, just as in the web engineering field, however, are not based on meta-models and standards, like OMG's prominent Meta Object Facility (MOF). Instead they define proprietary languages rather focused on notational aspects. Thus, ...

Computer mediated communication (CMC) and electronic markets have seen tremendous growth due to the fast propagation of the internet. In spite of the numerous benefits of electronic communication, it is not without its pitfalls. Two characteristics of computer mediated communication have proven to be particularly problematic: online anonymity and the enormity of data present in cyber communitie...

This paper presents the second round of the task on Cross-lingual Textual Entailment for Content Synchronization, organized within SemEval-2013. The task was designed to promote research on semantic inference over texts written in different languages, targeting at the same time a real application scenario. Participants were presented with datasets for different language pairs, where multi-direc...
