O uso da teoria de conjuntos aproximados na modelagem de bases de dados relacionais e na extração de conhecimento.
(Universidade Federal de São Carlos, 2005-05-13)
This work investigates two relational database models that extend the standard relational database model. Both models extend the standard relational model by allowing ways to represent
uncertainty. The rough relational ...
Um sistema inteligente para o seqüenciamento da produção com o apoio de simulação
(Universidade Federal de São Carlos, 2006-10-15)
The production sequencing is an area of great importance in Production Planning and Control, because businesses are looking for higher productivity and competitivity, in order to meet the demands and expectations of their ...
ExtraWeb: um sumarizador de documentos Web baseado em etiquetas HTML e ontologia
(Universidade Federal de São Carlos, 2006-07-10)
This dissertation presents an automatic summarizer of Web documents based on
both HTML tags and ontological knowledge. It has been derived from two independent
approaches: one that focuses solely upon HTML tags, and ...
Um estudo comparativo de modelos baseados em estatísticas textuais, grafos e aprendizado de máquina para sumarização automática de textos em português
(Universidade Federal de São Carlos, 2010-12-21)
Automatic text summarization has been of great interest in Natural Language Processing due to the need of processing a huge amount of information in short time, which is usually delivered through distinct media. Thus, ...
Uma abordagem ACO para a programação reativa da produção
(Universidade Federal de São Carlos, 2010-06-28)
In the context of automated manufacturing systems, combinatorial optimization problems, such as determining the production schedule, have been focused in many studies due to the high degree of complexity to their resolution. ...
Uma abordagem para construção de sistemas fuzzy baseados em regras integrando conhecimento de especialistas e extraído de dados
(Universidade Federal de São Carlos, 2015-09-17)
Historically, since Mamdani proposed his model of fuzzy rule-based system, a lot has changed in the construction process of this type of models. For a long time, the research efforts were directed towards the automatic ...
Extração de conhecimento simbólico de redes neurais.
(Universidade Federal de São Carlos, 2005-02-23)
The fact that Artificial Neural Networks (ANNs) are not able to explain, in a symbolic
way, neither their decisions or the knowledge embedded in its connections and architecture
is a well-known limitation. This work ...
Aprendizado supervisionado usando redes neurais construtivas
(Universidade Federal de São Carlos, 2006-05-25)
Constructive neural learning is a neural learning model that does not assume a fixed
network topology before training begins. The main characteristic of this learning model is the
dynamic construction of the network s ...
Recuperação de informação com auxílio de extratos automáticos
(Universidade Federal de São Carlos, 2006-05-08)
This dissertation investigates the use of Automatic Summarization (AS) techniques on
Information Retrieval (IR), two areas that have attracted growing attention due to the
continuous growth of information repositories ...
A resolução de anáforas pronominais da língua portuguesa com base no algoritmo de Mitkov
(Universidade Federal de São Carlos, 2007-08-22)
One of the problems of natural language processing systems is to assure
referential cohesion in a text. This property allows connecting the text constituents and
making it readable. We address the anaphoric phenomenon ...
