Paulo R. M. Correia; Ian M. Kinchin; Adriano N. Conceição – Knowledge Management & E-Learning, 2023
The evolution of concept mapping has benefitted from the robust theoretical basis provided by Ausubelian learning theory. However, for concept mapping to maintain its relevance and to keep pace with the evolutionary changes in the educational context, it is vital that educational researchers and classroom practitioners can augment this theoretical…

Oosterhof, Albert – Online Submission, 2012
Declarative knowledge involves being able to state and explain characteristics, terminologies, properties, phenomena, concepts, principles, and techniques. Chi and Ohlsson (2005) characterize it as the dominant form of knowledge, maintaining that it does not involve isolated units but rather is organized as semantic networks, theories, schemas, or…

Papasalouros, Andreas; Kotis, Konstantinos; Kanaris, Konstantinos – Interactive Learning Environments, 2011
The aim of this article is to present an approach for generating tests in an automatic way. Although other methods have been already reported in the literature, the proposed approach is based on ontologies, representing both domain and multimedia knowledge. The article also reports on a prototype implementation of this approach, which…

Suraweera, Pramuditha; Mitrovic, Antonija; Martin, Brent – International Journal of Artificial Intelligence in Education, 2010
Intelligent Tutoring Systems (ITS) are effective tools for education. However, developing them is a labour-intensive and time-consuming process. A major share of the effort is devoted to acquiring the domain knowledge that underlies the system's intelligence. The goal of this research is to reduce this knowledge acquisition bottleneck and better…

Evans, Vyvyan – Language Learning, 2008
Recent work addressing the phenomenon of perceptual simulation offers new and exciting avenues of investigating how to model knowledge representation. From the perspective of language, the simulation approach has given rise to new impetus to work on models of language understanding (e.g., Zwaan, 2004, and references therein), and provides a way of…

Jones, Michael N.; Mewhort, Douglas J. K. – Psychological Review, 2007
The authors present a computational model that builds a holographic lexicon representing both word meaning and word order from unsupervised experience with natural language. The model uses simple convolution and superposition mechanisms to learn distributed holographic representations for words. The structure of the resulting lexicon can account…

Gilbert, Jane – Education Canada, 2007
Over the last five years, people have heard a great deal about something called the Knowledge Society. The term "knowledge" is appearing in places they would not have expected to see it a decade or so ago. The media is full of references to the knowledge economy and the knowledge revolution; business discussions now routinely talk about knowledge…

Koyama, Masafumi; Morita, Kazuhiro; Fuketa, Masao; Aoe, Jun-Ichi – Information Processing & Management, 1998
Presents a faster method for determining hierarchical relationships in information retrieval by using trie structures instead of a linear storage of a concept code. Highlights include case structures, a knowledge representation for natural-language understanding with semantic constraints; a compression algorithm of tries; and evaluation.…

Bouzeghoub, Amel; Defude, Bruno; Duitama, John Freddy; Lecocq, Claire – International Journal on E-Learning, 2006
Our claim is that semantic metadata are required to allow a real reusing and assembling of learning objects. Our system is based on three models used to describe the domain, learners, and learning objects. The learning object model is inspired from knowledge representation proposals. A learning object can be reused directly or can be combined with…

Atlam, El-Sayed; Morita, K.; Fuketa, M.; Aoe, Jun-ichi – Information Processing & Management, 2002
Discusses automatic document classification and document retrieval systems and presents a strategy for building a morphological machine dictionary of English that infers meaning of derivations by considering morphological affixes and their semantic classification. Proposes a method for selecting compound field association terms from a large pool…

Scheuermann, Peter; Li, Wen-Syan; Clifton, Chris – Journal of the American Society for Information Science, 1998
Presents an approach for dynamic database integration and query processing in the absence of information about attribute correspondences and global IDs. Defines different types of equivalence conditions for the construction of global IDs. Proposes a strategy based on ranked role-sets that makes use of an automated semantic integration procedure…

Ingwersen, Peter – Journal of Documentation, 1996
Discusses the basic elements of a global cognitive theory for information retrieval (IR) interaction from a cognitive point of view. Within this framework are outlined the principles underlying the concept of polyrepresentation applied simultaneously to the user's cognitive space and the information space of IR systems. Contains 95 references.…

Chen, Hsinchun – D-Lib Magazine, 1999
Discusses the need for semantic research in digital libraries to help overcome interoperability problems. Highlights include federal initiatives; semantic analysis; knowledge representations; human-computer interactions and information visualization; and the University of Illinois DLI (Digital Libraries Initiative) project through partnership with…

Moreale, Emanuela; Vargas-Vera, Maria – Educational Technology & Society, 2004
This paper outlines an e-Learning services architecture offering semantic-based services to students and tutors, in particular ways to browse and obtain information through web services. Services could include registration, authentication, tutoring systems, smart question answering for students' queries, automated marking systems and a student…
