Classification accuracy: Machine learning vs. explicit knowledge acquisition

Machine Learning and Knowledge Acquisition Acknowledgment Machine Learning and Knowledge Acquisition 4.3. Axiomatization

427 D. Fensel and R. Groenboom choose and the range constructs, cf. [7]). Otherwise, current operationalizations and axiomizations of ealgebras are restricted to the case of point-wise updates. A further difference to our approach is that MLPM provides a richer vocabulary to express control over the execution of transitions. The language DESIRE uses the notion of meta-layered compositional arch...

Knowledge Acquisition with a Knowledge-Intensive Machine Learning System

In this paper, we investigate the integration of knowledge acquisition and machine learning techniques. We argue that existing machine learning techniques can be made more useful as knowledge acquisition tools by allowing the expert to have greater control over and interaction with the learning process. We describe a number of extensions to FOCL (a multistrategy Horn-clause learning program) th...

Transductive Learning for Text Classification Using Explicit Knowledge Models

We present a generative model based approach for transductive learning for text classification. Our approach combines three methodological ingredients: learning from background corpora, latent variable models for decomposing the topic-word space into topic-concept and concept-word spaces, and explicit knowledge models (light-weight ontologies, thesauri, e.g. WordNet) with named concepts for pop...

Combining Knowledge Acquisition and Machine Learning to Control Dynamic Systems

This paper presents an interactive method for building a controller for dynamic systems by using a combination of knowledge acquisition and machine learning techniques. The aim is to build the controller by acquiring the knowledge of an operator skilled at that task. This method has been demonstrated for the skill of learning to f i l l an aircraft in a flight simulator. The simulator has been ...
