The main technique employed in this type of system is the Collaborative Filtering (CF) which recommends products to a target-user based on known past evaluations of products made by other users who have similar preferences. However, the traditional CF approaches neglect the fact that the user taste may change over time and do not consider the rich temporal information that is contained in sequentially-ordered user interactions with products. Therefore, in this Doctoral Thesis, we have studied and researched on the current state of these systems, paying special attention to CF based on neighborhood, in order to propose the String-Recommender, which is a framework that combines several proposed variants of string-comparison measures used as similarity functions between users to seven proposed CF-based recommendation strategies. All the adopted string-comparison measures take into consideration time-ordered data, so our framework introduces a general and transparent modeling to adapt timestamped user's interaction to sequences. In addition to the definition of the new recommenders, this study is complemented with experimental results using two proposed temporal-based evaluation protocols in five well-known datasets in the area. As a summary, during the conducted experiments, the results show that our methods lead to more effective recommendations considering ranking measures on different recommendation list sizes, even in scenarios in which the rate of evaluated items per user is very low. Finally, the results lead us to also proposed a very robust and significant Validation Process that verifies the the effectiveness of a list of recommendation methods in future scenarios.},\n  keywords = {Recommender Systems, Collaborative Filtering, Temporal dynamics, String-comparison measures, Similarity Functions},\n  url      = {https://repositorio.bc.ufg.br/tede/},\n}\n\n\n

However, many traditional methods for determining similarity do not consider temporal information neither the rich information that is contained in sequentially-ordered user interactions. Therefore, the present work proposes the usage of traditional string comparison approaches for defining new similarity measures between pairs of users that take into consideration time-ordered data. The general idea is to model the similarity computation between users as an approximate string matching problem and to employ classical algorithms that solve it. Experiments conducted in different application domains demonstrate that the measures based on a string-comparison approach can improve accuracy.

As a result, the first version of a system with an architecture composed of a mobile frontend that communicates with a backend through a REST API was published, with satisfactory performance evaluation by the applicant. Other results involve the use of active learning techniques to reduce human effort when performing the classification of documents, as well as the Uncertainty strategy to choose the document to be labeled. The effectiveness of the stop criterion for the active learning technique based on confidence level was tested and proved unsatisfactory, remaining as a future work.},\n  doi       = {10.5753/kdmile.2020.11965},\n  issn      = {0000-0000},\n  keywords  = {document classification, active learning, annotation tool, document labeling, legal text},\n  location  = {Evento Online},\n  url       = {https://sol.sbc.org.br/index.php/kdmile/article/view/11965},\n}\n\n

Obtaining a good schedule results in the maximization of some desired benefit. In particular, in educational institutions (from elementary school to universities) this problem is periodically experienced, either during the preparation of class-teacher or examination timetabling. When a solution proposal is being elaborated (manual, semi-automatic or automatic processes), it is common the occurrence of the phenomenon called conflict, clash or collision. It is characterized by the simultaneous use of a resource (human or material) that can not be shared and, therefore, its occurrence makes that proposal impracticable for adoption. In semi-automatic systems, it is common the identification of such problems and, through user interaction, its resolution. Automatic systems, on the other hand, try to identify/solve conflicts without user intervention. Despite this, conflicts are not easy to resolve. This article proposes the use of information visualization techniques as an approach to highlight the occurrence of conflicts and, using user hints, contribute to its resolution, aiming at obtaining better quality timetables for practical adoption. The proposed visualizations were evaluated in order to determine its expressiveness and effectiveness, considering four aspects: coverage of the research questions, efficiency of the adopted visual mapping, supported level of human interaction and scalability. A conceptual qualitative study showed that the use of these techniques can aim users, mainly non-specialized, to identify conflicts and improve the desired educational timetables.},\n  doi       = {10.1007/978-3-030-33720-9_21},\n  isbn      = {978-3-030-33720-9},\n  keywords  = {Timetabling Problem,Scheduling Problem, Educational, Conflict, Clash, Collision, Violation, Information Visualization, User Hints, User-driven, Interactive application},\n  url       = {https://doi.org/10.1007/978-3-030-33720-9_21},\n}\n\n

Traditional methods for determining similarity depends on considerable amount of data regarding people's preferences and features. Those methods present limitations when the data is scarce and/or changes constantly. This paper introduces a new method for determining people similarity that does not suffer from the same problems. The method can learn a customized similarity function based on social variables of friends that attend the same events (concerts, parties, conferences etc), collected from social networks. Two types of optimization algorithms for learning a similarity function are presented: The universal function approximator modelling, which relays on the relationship of social attributes and a friends' importance ranking; and the populational evolutionary modelling, which linearly combines social variables. Both models were tested in a generalist and in a specialist approach. The results show that the specialist approach exceeded in almost 38 % the generalist approach using populational evolutionary methods and in almost 69 % when using the universal function approximator methods. Among the implemented optimization algorithms employed inside the methods for learning similarity, Genetic Algorithm and Particle Swarm Optimization presented better performance for the populational evolutionary methods and the Artificial Neural Network presented the best performance overall using the universal function approximator modelling.},\n  doi       = {10.1109/CEC.2018.8477864},\n  keywords  = {function approximation;genetic algorithms;learning (artificial intelligence);neural nets;particle swarm optimisation;social networking (online);social networks;universal function approximator modelling;social attributes;populational evolutionary modelling;social variables;universal function approximator methods;social information;social dynamics;people similarity;customized similarity function;evolutionary methods;optimization algorithms;friends attendance;particle swarm optimization;Genetic Algorithm;similarity function learning;artificial neural network;Optimization;Facebook;Approximation algorithms;Heuristic algorithms;Genetic algorithms;Scholarships;Social Dynamics;Similarity Function;Optimization Algorithms;Social Events},\n  url       = {https://doi.org/10.1109/cec.2018.8477864},\n}\n\n\n

Este novo trabalho consiste de dois ambientes conectados para gerar e experimentar novos códigos de programação para os cubos. O primeiro é um sistema de realidade virtual na Web, em que o participantes podem experimentar e avaliar versões virtuais dos cubos, com códigos que mudam por meio de um processo de computação evolucionária. O segundo ambiente consiste de uma instalação física na qual pessoas podem experimentar os cubos reais, atualizados automaticamente com os melhores códigos gerados previamente pelo sistema na Web. Os usuários não escrevem códigos para os cubos, de forma explícita, os códigos são modificados pelo processo de computação evolucionária usando os resultados das avaliações humanas. Este trabalho apresenta uma exploração do potencial de guiar um sistema evolutivo interativo para a criação de novos comportamentos para objetos reais, ao mesmo tempo em que procura estabelecer uma relação mais imediata entre o que é produzido em um ambiente virtual e o que pode ser experimentando em um espaço físico real.},\n  issn         = {2358-0488},\n  keywords     = {Cubos interativos, computação evolucionária, ambiente virtual, instalação física},\n  owner        = {hugo},\n  timestamp    = {2018.11.05},\n  url          = {https://siimi.medialab.ufg.br/p/25047-anais-2018},\n}\n\n

The system covered in this article, called PetGyn, falls into this category. It is powerful enough to represent scenarios of changes in the structure of road networks and/or in the behavior of their elements (pathways, traffic lights, possible conversions, etc.) and for predicting road usage levels (volume and traffic speed). In addition, PetGyn's flexibility allows the employment of different traffic allocation models (system optimization, user equilibrium, etc.), various types of cost functions (from the classic BPR - Bureau of Public Roads - arc cost functions to non-separable and asymmetric functions) and the simulation of different behaviors for the road network components (blocking routes according to schedules/days, reversing the direction of traffic flows, allowing/forbidden parking along the lanes, among others). Since its conception, it was built in a modular way so that it can be easily adapted to the urban traffic particularities of any country. Unlike commercial systems in this area, PetGyn was developed under a free software philosophy and as a web-based system in order to favor collaborative work. Its usage allows the study of intervention projects for medium-sized metropolitan regions, contributing to identify possible improvements in urban mobility.},\n  doi       = {10.1109/S3C.2017.8501405},\n  isbn      = {978-1-5386-1063-3},\n  issn      = {null},\n  keywords  = {groupware;Internet;public domain software;road traffic;roads;town and country planning;traffic engineering computing;Brazilian urban traffic planning system;urban traffic simulators;road networks;vehicular mobility;road usage levels;traffic flows;urban mobility;Public Roads;urban traffic;Web-based system;traffic allocation models;PetGyn 2.0;free software;collaborative work;Roads;Urban areas;Mathematical model;Vehicles;Cost function;Proposals;Resource management;Traffic control;modeling;computer simulation;web services;open source software.},\n}\n\n\n

The algorithm is based on Floyd-Warshall and, therefore, borrows some of its advantages as having a predictable performance regardless of the underlying graph structure. It was efficiently implemented on a machine with a many-core GPU, which is less expensive than a cluster of computers. The tests were performed on a Tesla C2075 graphics card. The implementation was able to identify the shortest paths among all pairs of vertices of randomly generated graphs (all containing a maximum of 8192 vertices) in less than 15 seconds, which represents a speedup of 150x over the sequential Floyd-Warshall algorithm.},\n  comment   = {Apr 5-7, 2016. http://on-demand-gtc.gputechconf.com/gtc-quicklink/gL5SW},\n  keywords  = {Algorithms, Performance Optimization},\n  owner     = {hugo},\n  timestamp = {2018.06.16},\n  url       = {http://on-demand.gputechconf.com/gtc/2016/posters/GTC_2016_Algorithms_AL_02_P6272_WEB.pdf},\n}\n\n

The increasing amount of vehicles combined with limited road infrastructure result in traffic congestion and in several other traffic-related issues such as fuel wastage, time losses, health problems and environmental pollution. As an attempt to mitigate these problems, much research has been done and tools developed for the study and improvement of urban traffic conditions. However, visualizing Origin-Destination (OD) matrices, an important element of urban traffic studies, is still a challenge. In general, showing OD matrices in an effective way involves considering georeferenced temporal aspects, traffic multimodality and large volumes of data; factors that have not been fully addressed by the existing approaches. This paper proposes a new visual representation for OD matrices that deals with these factors, filling a gap in this area.},\n  affiliation         = {Instituto de Inform{\\'a}tica - Universidade Federal de Goi{\\'a}s, Campus II, Goi{\\^a}nia - Goi{\\'a}s, Brasil and Instituto de Inform{\\'a}tica - Universidade Federal de Goi{\\'a}s, Campus II, Goi{\\^a}nia - Goi{\\'a}s, Brasil and Faculty of Computer Science Dalhousie University, Halifax - Nova Scotia, Canada},\n  conference-location = {Salvador-BA},\n  conference-year     = {Aug. 26-29, 2015},\n  keywords            = {Urban traffic, congestion of vehicles, information visualization, Origin-Destination matrices.},\n  language            = {en},\n  targetfile          = {SibiGrapi2015WvisHalleyGondim.pdf},\n  url                 = {http://urlib.net/sid.inpe.br/sibgrapi/2015/08.20.23.43},\n  urlaccessdate       = {2015, Nov. 16},\n}\n\n

We focused on machine learning strategies that build up and represent knowledge about how to draw a graph. Surprisingly, only a few pieces of research can be found about this subject. We classified them in two main groups: the ones that extract knowledge from the user by human-computer interaction and those that are not based on data directly gathered from users. The study of these methods shows that there is still much to research and to develop regarding the application of machine learning to graph drawing.

Its development mobilized a multidisciplinary team that had to deal with topics such as autopoiesis, tangible interfaces, combinations of behavioral states, interactivity and technological art. The team worked on requirement identification, design of physical structures, design of hardware and software, and assembly and test of the final solution. The cubes were shown in an international exhibition, during which a preliminary evaluation was done. The experience in having a multidisciplinary and collaborative project is commented.},\n  doi       = {10.5151/despro-sigradi2015-70382},\n  keywords  = {Interactive Cubes, Behavioral States, Sound and Luminous Feedback},\n  owner     = {hugo},\n  timestamp = {2018.06.16},\n  url       = {http://sigradi2015.sites.ufsc.br/, http://www.proceedings.blucher.com.br/article-details/c-cubos-interativos-22332},\n}\n\n

The interface consists of three large, but light cubes that can be lifted, rotated and moved in a room by a group of people. Each cube detects its orientation (which side is positioned on the top) and the proximity to the other cubes. For simplicity, proximity between any pair of cubes was defined only as near (up to 2 meters) and far (above 2 meters). This set of three cubes allows $6^3$ combinations of upside positioning. Considering only proximity, 5 different setups are possible (no cube near the others, all three cubes nearby, and three pairwise proximity combinations). In total, the setup offers $6^3$ x 5 = 1,080 combinations. Each one of them can be assigned to a different output involving blinking of lights and sound feedback. The sides of the cubes can be painted with pictures. The interface was thought as a way of transmitting new concepts to the users, for instance, in an educational environment. Motivational activities and pure entertainment are also possible applications for $C^3$. These goals can be reached by assigning the above mentioned combinations to specific feedbacks. The intensity of the feedbacks can be designed to guide the users to one or more targeting configurations, in which the images of the three cubes, when visualized together, compose a new concept. For the current exhibition, $C^3$ is programmed to highlight a poetic perspective in a ludic way. The ludic aspect acts as a motivational element and the poetic perspective is defined by the combinatorial setups of the cubes. High peaks in the behavior of the system, triggered by the user by a series of actions, are composed of sounds and kaleidoscopic lights for some preconfigured combinations.},\n  owner        = {hugo},\n  timestamp    = {2018.06.16},\n}\n\n

This paper presents an overview of what has been done on this topic by reviewing the use of information visualization in traffic systems over the years, and highlighting the current state-of-the-art by focusing on several innovative pieces of research.

However, they have focused mostly on counting the amount of written lines of code and the number of commits, which are general information that can be obtained from these software repositories. In the present article, we innovate by considering fine-grain operations at line and file levels stored in the VCS, like additions, deletions and modifications, which allow to derive a much more detailed and rich information about the work done by developers. We also define a new set of metrics to measure such fine-grain information and present two simple approaches for comparing developers based on the proposed metrics. This helps to improve our understanding of how important and alike the developers were. A case study using data from a real software development project is described. The study showed that the metrics and the comparative approaches resulted in information that is consistent with the perception of the project manager. Furthermore, our investigation points to a great potential for future work by expanding the set of metrics and exploring new comparative approaches.},\n  Comment                  = {ISBN 9781479942237},\n  Doi                      = {10.1109/SBES.2014.25},\n  Keywords                 = {configuration management;software metrics;VCS;data extraction;file levels;fine-grain operations;line levels;project manager perception;real software development project;software repositories;version control system;Control systems;Data mining;Data structures;History;Measurement;Software;Teamwork;comparison of software developers;metrics;version control systems},\n  Url                      = {http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6943481}\n}\n\n
