System self-contextualizability is the system ability to autonomously adapt its behavior to the uncontrollable relevant context to keep its objectives satisfied. Self-contextualizable system must have alternative behaviors each fitting to a set of contexts. We propose to start considering context at the level of requirements engineering, adopting Tropos goal model to express requirements and co...

This paper reports on our current experiments involving the Snippet and Tweet Contextualization Tracks of the 2012 INEX competition. Most of this work in snippet generation extends our earlier (2011) approach, described in [4], which produced a top-ranked result. The source of the snippet in these experiments is the top-ranked focused element(s) of the document in question. Another approach is ...

The paper reports an empirical study of the use of videoconferences in decentralized university education. The study focuses on breakdowns that occur during the transition of educational practices from regular classrooms to videoconference-based environments. It was found that the breakdowns were mainly caused by physical and organizational distribution of decentralized education. The paper con...

According to the organizers, the objective of the 2013 INEX Tweet Contextualization Task is: “...The Tweet Contextualization aims at providing automatically information a summary that explains the tweet. This requires combining multiple types of processing from information retrieval to multi-document summarization including entity linking.” We present the Cortex summarizer applied to the INEX 2...
