In this paper, we present a system for automatically answering opendomain, multiple choice reading comprehension questions about short English narrative texts. The system is based on state-of-the-art text similarity measures, textual entailment metrics and coreference resolution and does not make use of any additional domain specific background knowledge. Each answer option is scored with a com...

This paper reports the Recognizing Textual Entailment (RTE) system that our ‘IKOMA team’ developed at TAC 2010. We implemented a new method that identifies entailment sentences using local-novelty detection. This method determines whether a Hypothesis (H) is local-novel. ‘H is local-novel’ means that H is the new information first appeared in TH , and TH denotes the text (T) that entails H. If ...

The Answer Validation Exercise at the Cross Language Evaluation Forum is aimed at developing systems able to decide whether the answer of a Question Answering system is correct or not. We present here the exercise description, the changes in the evaluation methodology with respect to the first edition, and the results of this second edition (AVE 2007). The changes in the evaluation methodology ...

This paper reports on the performance of a new system for recognizing textual entailment. We present a brief overview of the CERES system and summarize its semantic alignment method for determining entailment. Then, we describe the experiments that were performed, both official and subsequently, against the RTE4 test dataset. We also report on comparison runs against the previous RTE3 developme...

Social business intelligence combines corporate data with user-generated content (UGC) to make decision-makers aware of the trends perceived from the environment. A key role in the analysis of textual UGC is played by topics, meant as specific concepts of interest within a subject area. To enable aggregations of topics at different levels, a topic hierarchy has to be defined. Some attempts have...

this study was motivated by three factors, which also contribute to its significance for today’s academic writing. first, research articles are the significant means of communication between the writers all over the world. second, persuasion and organization are crucial notions in academic writing where the authors have to consider the academic audiences and their needs.  third, some writers ar...

Specifying queries on models is a prerequisite to model transformations in the MDA because queries select the model elements that are the source of transformations. Current responses to OMG's MOF 2.0 QVT RFP mostly propose to use (and/or extend) OCL 2.0 as specification language for queries. In this paper, we demonstrate that using textual notations (like OCL) quickly leads to complex query sta...

In this paper, we present a systematic framework for a fast and easy implementation and deployment of a recommendation system for one or several Websites, based on any available combination of open source tools that include crawling, indexing, and searching capabilities. The supported recommendation strategies include several popular flavors such as content based filtering (straight forward), c...
