Bayesian BDI agents and approaches to desire selection
(2013) [Tesis de maestría]The reasoning performed in BDI agents essentially involves manipulating three data structures representing their beliefs, desires and intentions. Traditional BDI agents’ beliefs do not represent uncertainty, and may be ... -
BB25HLegalSum : a method for legal document summarization that leverages BM25 and BERT-based clustering
(2024) [Tesis de maestría]Legal document summarization aims to provide a clear understanding of the main points and arguments in a legal document, contributing to the efficiency of the judicial system. In this work, we propose BB25HLegalSum, a ... -
A BDI-based approach for the assessment of driver's decision-making in commuter scenarios
(2002) [Tesis]The rapid growth of urban areas has a significant impact on traffic and transportation systems. New management policies and planning strategies are clearly necessary to cope with the more than ever limited capacity of ... -
Bee clustering : um algoritmo para agrupamento de dados inspirado em inteligência de enxames
(2009) [Tesis de maestría]Agrupamento de dados é o processo que consiste em dividir um conjunto de dados em grupos de forma que dados semelhantes entre si permaneçam no mesmo grupo enquanto que dados dissimilares sejam alocados em grupos diferentes. ... -
A benchmark suite for distributed stream processing systems
(2017) [Tesis de maestría]Recently a new application domain characterized by the continuous and low-latency processing of large volumes of data has been gaining attention. The growing number of applications of such genre has led to the creation of ... -
Beyond accuracy : completeness and relevance metrics for evaluating long answers
(2024) [Tesis]The development of Question Answering (QA) systems that provide long answers face significant challenges in assessing the quality of these answers. Developing metrics ca pable of evaluating specific criteria individually, ... -
Beyond digital, imagens, and forensics : towards a regulation of trust in multimedia communication
(2018) [Tesis]This thesis discusses the role of Digital Image Forensics as a regulator of digital media in society. This includes a perceptual study with over 400 subjects to assess their ability to notice editing in images. The results ... -
