The Role of Domain Knowledge in Search as Learning

O'Brien, Heather, 1977-, Andrea Kampen, Amelia Cole, Kathy Brennan
The purpose of this paper is to explore the differences in learning outcomes between domain experts and non-experts interacting with a digital library.  ...  General searchers wrote longer summaries than domain experts, but there were no significant differences in the learning outcomes between the two groups.  ...  Conclusion This study aims to better understand the role of domain expertise in learning outcomes.  ...

Integrating models of knowledge and Machine Learning [chapter]

Jean-Gabriel Ganascia, Jérôme Thomas, Philippe Laublet
1993 Lecture Notes in Computer Science  
This paper shows how the input of a Machine Learning system can be mapped to the model of expertise as it is used in KADS methodology. The notion of learning bias will play a central role.  ...  Doing this conceptual mapping, we give a semantics to most of the inputs of Machine Learning programs in terms of knowledge acquisition models.  ...  A metaclass (or a role) describes the role of domain entities in the problem-solving process and it is linked to the domain concepts which fulfil this role.  ...

An Ontological Approach to Support Personalized E-Learning System

Kalla MadhuSudhana, V. Cyril Raj, K. T. Sikamani
2013 International Journal of Computer Applications  
The learner-model and domain-model plays an important role for delivering personalized learning material to learner.  ...  Learners who use educational applications need to get suitable learning material in their concerned domain. However, their level of knowledge, preferences and interests are different.  ...  In e-learning systems the learner preferences from the perspective of learning domain and educative support information, plays an important role to implement successful educational applications.  ...

A Framework for the Generation of Adaptive Courses Based on Semantic Metadata

2005 Multimedia tools and applications  
In this way, it is possible both searching components developing concepts not appearing in the user query but related with user goals and inferring user knowledge that is not explicit in user model.  ...  Our approach proposes the creation and management of adaptive learning systems by combining component technology, semantic metadata, and adaptation rules.  ...  At learning time, for each couple (domain-concept, role) from Content of C k : f(A) adds <domain-concept, role, new-knowledge-level> in UM or FAIL.  ...

A General Introspective Reasoning Approach to Web Search for Case Adaptation [chapter]

David Leake, Jay Powell
2010 Lecture Notes in Computer Science  
The second extension applies reinforcement learning to the problem of selecting knowledge sources to mine, in order to manage the exploration/exploitation tradeoff for system knowledge.  ...  The benefits and generality of these extensions are assessed in evaluations applying them in three highly different domains, with encouraging results.  ...  We are currently studying processing time behavior and the role of search case retention strategies in reducing search time [21] .  ...

Learning to improve case adaptation by introspective reasoning and CBR [chapter]

David B. Leake, Andrew Kinley, David Wilson
1995 Lecture Notes in Computer Science  
We describe the tenets of the approach and the types of knowledge it requires. We s k etch initial computer implementation, lessons learned, and open questions for further study.  ...  The ability to de ne those rules depends on knowledge of the task and domain that may not be available a priori, presenting a serious impediment to endowing CBR systems with the needed adaptation knowledge  ...  In contrast, using case-based reasoning as the learning method for adaptation knowledge makes it possible for learned knowledge to re ect the idiosyncrasies of the memory's organization and its contents  ...

Supporting Formal and Informal Learning through Domain Ontologies

Paola Monachesi
2012 International Journal of e-Education, e-Business, e-Management and e-Learning  
One of the objectives of the Language Technology for LifeLong Learning project is to develop services that facilitate learners and tutors in accessing formal and informal knowledge sources.  ...  Ontologies are central to the knowledge discovery process and they facilitate reuse of course material through semantic search of annotated learning objects, supporting thus formal and informal learning  ...  The learner needs to acquire at least two kinds of knowledge in his learning path: the domain knowledge and the skills necessary to apply the domain knowledge in a community of practice.  ...

A Study on Ontology Application Scenarios in e-Learning Domain

Kalla Madhusudhana
2017 International Journal of Computer Applications  
However, searching appropriate learning resources for a learner from a large number of heterogeneous knowledge sources is a tedious task.  ...  Finally we proposed the different strategies to be considered while developing ontologies in management, presentation and retrieval of the material in elearning domain.  ...  Ontologies have the potential to play an important role in representing knowledge about content to support learners in accessing content in a knowledge-guided way.  ...

Searching for representations to improve protein sequence fold-class prediction

Thomas R. Ioerger, Larry A. Rendell, Shankar Subramaniam
1995 Machine Learning  
The methods developed in this domain are generalized into a framework that suggests several systematic roles for domain knowledge in machine learning.  ...  Learning in such domains can be improved by using domain knowledge to search for representations that better match the inductive bias of a preferred algorithm.  ...  We would like to thank the National Center for Supercomputing Applications for providing computational resources. We would also like to thank the anonymous Machine Learning reviewers.  ...
