Enhanced hypertext categorization using hyperlinks
, 1998
"... A major challenge in indexing unstructured hypertext databases is to automatically extract meta-data that enables structured search using topic taxonomies, circumvents keyword ambiguity, and improves the quality of search and profile-based routing and filtering. Therefore, an accurate classifier is ..."

. Naive use of terms in the link neighborhood of a document can even degrade accuracy. Our contribution is to propose robust statistical models and a relaxation labeling technique for better classification by exploiting link information in a small neighborhood around documents. Our technique also adapts
Forward models: Supervised learning with a distal teacher
- Cognitive Science
, 1992
"... Internal models of the environment have an important role to play in adaptive systems in general and are of particular importance for the supervised learning paradigm. In this paper we demonstrate that certain classical problems associated with the notion of the \teacher " in supervised lea ..."

learning can be solved by judicious use of learned internal models as components of the adaptive system. In particular, we show how supervised learning algorithms can be utilized in cases in which an unknown dynamical system intervenes between actions and desired outcomes. Our approach applies to any
Service-oriented computing: concepts, characteristics and directions

"... Service-Oriented Computing (SOC) is the computing paradigm that utilizes services as fundamental elements for developing applications/solutions. To build the service model, SOC relies on the Service Oriented Architecture (SOA), which is a way of reorganizing software applications and infrastructure ..."

The neural basis of human error processing: Reinforcement learning, dopamine, and the error-related negativity
- PSYCHOLOGICAL REVIEW 109:679–709
, 2002
"... The authors present a unified account of 2 neural systems concerned with the development and expression of adaptive behaviors: a mesencephalic dopamine system for reinforcement learning and a “generic ” error-processing system associated with the anterior cingulate cortex. The existence of the error ..."

1 MOSES: a Framework for QoS Driven Runtime Adaptation of Service-oriented Systems
"... Abstract—Architecting software systems according to the serviceoriented paradigm, and designing runtime self-adaptable systems are two relevant research areas in today’s software engineering. In this paper we address issues that lie at the intersection of these two important fields. First, we presen ..."

present a characterization of the problem space of self-adaptation for service-oriented systems, thus providing a frame of reference where our and other approaches can be classified. Then, we present MOSES, a methodology and a software tool implementing it to support QoS-driven adaptation of a service-oriented
A Unifying Review of Linear Gaussian Models
, 1999
"... Factor analysis, principal component analysis, mixtures of gaussian clusters, vector quantization, Kalman filter models, and hidden Markov models can all be unified as variations of unsupervised learning under a single basic generative model. This is achieved by collecting together disparate observa ..."

We introduce a new model for static data, known as sensible principal component analysis, as well as a novel concept of spatially adaptive
Runtime Behavior Monitoring and Self-Adaptation in Service-Oriented Systems
"... Abstract—Mixed service-oriented systems composed of human actors and software services build up complex interaction networks. Without any coordination, such system may exhibit undesirable properties due to unexpected behavior. Also, communications and interactions in such networks are not preplanned ..."

Consequently, the management of service-oriented applications is difficult due to changing interaction and behavior patterns that possibly contradict and result in faults from varying conditions and misbehavior in the network. In this paper we present a self-adaptation
Agile Service-Oriented Applications: Rule-based Foundation with Runtime Adaptability
"... Service-oriented applications are increasingly requested to be adaptive and reliable, to face harsh market competitiveness and volatility. Towards achieving that, service developers must foster current ad-hoc and rigid available technology, e.g. WSDL, BPEL and WS-CDL, with early formal specification ..."
