A chatbot or conversational agent is a software that can interact ``chat'' with human user using natural language, like English, for instance. Since the first developed, many have been created but most of their problems still persist, providing right answer to and acceptance itself. Considering such facts, in this work, we present chatbot-building framework considers use sentiment analysis tree...

In the world of supercomputers, the large number of processors requires to minimize the inefficiencies of parallelization, which appear as a sequential part of the program from the point of view of Amdahl’s law. The recently suggested new figure of merit is applied to the recently presented supercomputer, and the timeline of ”Top 500” supercomputers is scrutinized using the metric. It is demons...

Factuality information gives evidence on whether the events in texts have happened. This information can be relevant in natural language processing tasks such as timeline generation as it helps discriminating the events that are relevant to a certain timeline. We analysed some factuality annotation schemes and proposed a new scheme that aims at concise and easy annotation. We worked on a Basque...

In this paper, we present GlobeMash, a mashup web application that uses standardized data formats like XML, JSON, LOM, SVG, CAM and protocols like SOAP, HTTP, to enable users to access the repositories of the Global Learning Objects Brokered Exchange (GLOBE) consortium. GlobeMash uses the Google Maps API to display the repositories and results on a geographical map, the Timeline API of the SIMI...

In this paper, we first illustrate the state-of-the-art in timetabling research w.r.t. two important research qualities, namely measurability and reproducibility, analyzing what we believe are the most important contributions in the literature. Secondly, we discuss some practices that, in our opinion, could contribute to the improvement on the two aforementioned qualities for future papers in t...

Preferential rules occur very often in application domains like timetabling. Besides absolutely valid rules like “Ground courses have to start in the morning in one of the main lecture rooms”, there are very often preferential rules like “A wish for the starting time of a lecture should be satisfied with less deviations” or “A wish for a room of a lecture should be satisfied if possible”. Our a...

Reading is an outstanding achievement of the human brain. The ability to read has substantially formed our history and culture and plays an essential role in our everyday lives. Skilled readers can hardly prevent processing a written stimulus and, most often, they grasp a word’s meaning within a fraction of a second. The understanding of the underlying mechanisms as well as the time course of t...
