Aprendizado genético de funções de pertinência na modelagem nebulosa.
(Universidade Federal de São Carlos, 2004-08-20)
The success of Fuzzy Rule Based Systems is due to their ability to represent vague and
uncertain knowledge and to the facility to express the system behavior in a language easily
interpretable by human beings. The knowledge ...
RHeSumaRST: um sumarizador automático de estruturas RST.
(Universidade Federal de São Carlos, 2005-08-05)
This work presents an automatic summarization model based on both the Rhetorical Structure Theory RST and the Veins Theory VT. RST allows inter-relating discourse units by means of rhetorical relations. These, in ...
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 ...
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 ...
Abordagem co-evolutiva hierárquica para geração automática de sistemas nebulosos
(Universidade Federal de São Carlos, 2006-09-13)
This work focuses on the problem of automatic generation of fuzzy systems
through evolutionary computation, specifically using the approach of co-evolution. Coevolution
is based on the idea of modular modeling of the ...
