Semantic similarity aims at quantifying the resemblance between the meaning of textual terms. Thus, it represents the corner stone of textual understanding. Given the increasing availability and importance of textual sources within the current context of Information Societies, a lot of attention has been put in recent years in the development of mechanisms to automatically measure semantic simi...

This paper describes the Sagan system in the context of the Fifth Pascal Recognizing Textual Entailment (RTE-5) Evaluation Challenge and the new Textual Entailment Search Pilot Task. The system employs a Support Vector Machine classifier with a set of 32 features, which includes lexical and semantic similarity for both two-way and three-way classification tasks. Additionally, we show an approac...

Intelligent, context sensitive content assist (also known as code completion) plays an important role in the effectiveness of model editors. This is not only true for textual language notations, but also for graphical notations that often contain a significant amount of textual elements. This paper presents techniques to describe content assists for meta-model based textual model editors. We sh...
