The recognition that different aspects of the urban environment can affect individuals' mental health is growing, as they are responsible for facilitating or inhibiting behaviors and lifestyles that affect sentiment. The increasing availability of user-generated data on social media provides information about users and their surroundings, enabling sentiment analysis. This study investigates the global production of documents on sentiment analysis and the built environment, urban or city, published between 2009 and 2023. Bibliometric indicators on trends, most cited articles, authors, institutions, countries, funding agencies, and thematic research areas were analyzed. The bibliometrix library of R software was used for the performance analysis and the VOSviewer software for mapping scientific connections. A total of 728 eligible papers were identified from 2009 to June 2023. Most publications were computer science papers (n=487). This type of analysis provides researchers with guidance on the possible critical points that can be found in this field of research, as well as informs about the multiplicity of scientific research conducted globally so far by authors, countries, sources, allocated funding, and active institutions, allowing improving the production of documents on sentiment analysis concerning the urban environment.

The use of teaching tools has become an alternative to complement the learning of school content. This paper provides some overview aspects of Compilation and performance analysis of the computational tools GALS, Grammophone, The Context Grammar Free Checker, Verto, and Parsing Simulator that were developed to support the compilation process and aim at assisting the learning in Compilers course. There are several known tools, but only a few were built for academic purposes and will be presented in this paper, as they were tested by students in the Compilers course in the Undergraduate course and also int the Master's course in Computer Science at a Brazilian Public University in Paraná to analyze hypotheses, to help verifying parsing examples and to exchange experiences about these Compiler tools. It was observed that the lexical and mainly syntactic analysis phases become more didactic and attractive to the students, making it easier to understand their functionalities and implementation of a compiler as a whole. GALS has shown to be a good option with a simple interface, working with lexical and syntactic analysis for more than one language (Java, C++ and Delphi). Studies of Context Free Grammars in LL(1), LR(0) and LR(1) format may be favored not only with GALS, but also with the tools Grammophone and The Context Grammar Free Checker. Verto, on the other hand, works didactically, not only on the lexical and syntactic analysis steps (the latter also with LR(1) Parser), but also on code generation. Parsing Simulator proved to be an intuitive tool and also presents an extensive collection of syntactic analysis options showing the step by step LL(1) and LR(K) analysis tables, promoting teaching-learning in Compilers.

The first year of an undergraduate major is a challenge for most students in the University of Brasilia. Of course, this challenge applies not only to them but to most first-year students at Brazilian and worldwide universities. This issue often leads the students to drop out of their majors. In this context, this paper presents the Program offered by the Department of Computer Science at the University of Brasilia to welcome new students to the major in a more friendly way. The program was carried out in its first edition in the first semester of 2020, and its methodology and lessons learned are presented. [ABSTRACT FROM AUTHOR]

This paper reports a needs analysis process to English for Academic Purposes courses, applied to Computer Science graduate students. The analysis aimed at determining both present and target situations in the use of the language, initially with 13, and after some modifications in the instrument, with 213 students. Results show, among other things, that a big part of the students have a positive view of their English language proficiency, revealing a need of tasks and approaches that consider such an image, in order to ensure bigger motivation and better performance of the students in the tasks of the course.

This paper discusses the traditional philosophical debate concerning body and spirit that has formed a multidisciplinary field of researches about brain and mind in the twentieth century, called cognitive sciences. Among the various divergent positions in this area, three of them had their nuances about the future of this exploited enterprise, and also their relations with the social sciences that basically move in these directions: (i) the defence of the singularity of human sciences' object considered in the philosophical consciousness model as intentionality; (ii) the searching of a biological understanding of the mind, also viewed in this case as intentionality and consciousness, and finally; (iii) the critic of the notions of intentionality and consciousness through the cybernetic and also the cognitive sciences achievements, that can feed a new relation between humans and machines.

In Natural Language Processing (NLP) domain, a lexical database, i.e. a systematic stock of words of a natural language, is a crucial component of a wide variety of NLP applications. In this paper, we present the interlingua used in the construction of the bilingual lexical database called REBECA, one of the few lexical resources that encompasses Brazilian Portuguese (BP) language. The interlingua is the core feature of REBECA and it is composed of a set of concepts which allows the alignment of the English and BP monolingual databases. Precisely, we present: (i) the composition; (ii) the structure, (iv) the formalism, and (v) the editing tool used to develop REBECA. . As a result, we obtained a formal and hierarchical interlingua, which allowed a proper link between the monolingual databases. [ABSTRACT FROM AUTHOR]
