Computational approaches to subjectivity and sentiment analysis: Present and envisaged methods and applications

Recent years have witnessed a surge of interest in computational methods for affect, ranging from opinion mining, to subjectivity detection, to sentiment and emotion analysis. This article presents a brief overview of the latest trends in the field and describes the manner in which the articles contained in the special issue contribute to the advancement of the area. Finally, we comment on the current challenges and envisaged developments of the subjectivity and sentiment analysis fields, as well as their application to other Natural Language Processing tasks and related domains.

EMOCause: an easy-adaptable approach to emotion cause contexts

In this paper we present a method to automatically identify linguistic contexts which contain possible causes of emotions or emotional states from Italian newspaper articles (La Repubblica Corpus). Our methodology is based on the interplay between relevant linguistic patterns and an incremental repository of common sense knowledge on emotional states and emotion eliciting situations. Our approach has been evaluated with respect to manually annotated data. The results obtained so far are satisfying and support the validity of the methodology proposed.

An experience on mechatronics teaching on undergraduate students by means of the Skybot platform: from classroom to robot competition

This paper analyzes the learning experiences and opinions from a group of undergraduate students in a course about Robotics. The contents of this course were taught as a set of seminars. In each seminar, the student learned interdisciplinary knowledge of computer science, control engineering, electronics and other fields related to Robotics. The aim of this course is that the students are able to design and implement their own and custom robotic solution for a series of tests planned by the teachers. These tests measure the behavior and mechatronic features of the students' robots. Finally, the students' robots are confronted with some competitions. In this paper, the low-cost robotic architecture used by the students, the contents of the course, the tests to compare the solutions of students and the opinion of them are amply discussed.

Arte contemporânea e meio ambiente no Museu Inhotim

Este estudo apresenta uma breve análise sobre o Museu Inhotim, considerado o maior museu a céu aberto do mundo. Nele, são expostas obras de Arte Contemporânea inseridas no meio ambiente, num processo de diálogo com a natureza, presente numa reserva florestal que era uma antiga fazenda. Entre jardins, arquitetura e arte, as obras também se relacionam entre si. No local são oferecidos passeios culturais, artísticos e educacionais, pois o museu conta com um setor educativo voltado para a educação através da reflexão sobre as obras de arte expostas e o meio ambiente, quanto à preservação do patrimônio ambiental e cultural. A arte, nesse contexto, ganha uma análise baseada em alguns conceitos sobre Arte Contemporânea, que se fundamentam em estudos propostos por autores como Giulio Carlo Argan, Umberto Eco, Michael Archer, Ernst Fischer, Fayga Ostrower, entre outros.
