In this paper we present KBAAA, a prototype system that provides a web-based interface for the analysis and assessment of knowledge base acceleration systems. KBAAA displays items from a voluminous document stream that are deemed central to a given target entity. Results can be visualised on a timeline along with the number of pageviews and edits made for that entity in the knowledge base. If a...

This study investigated the influences of learning styles/preferences, prior computer skills and experience with online courses on adult learners’ knowledge acquisition in a web-based special education course. Forty-six adult learners who enrolled in a web-based special education course participated in the study. The results of the study showed that (a) learning styles/preferences had significa...

Preserving and fostering knowledge is the vital interest of a network-like virtual organization. The decentralized and geographically distributed organizational structure inhibits knowledge flow. The particular conditions of knowledge management in virtual organizations are discussed by the example of an empirical study we carried out in a service company. We analyze how technical and organizat...

In this paper we describe the MBase system, a web-based, distributed mathematical knowledge base. This system is a mathematical service in MathWeb that ooers a universal repository of formalized mathematics where the formal representation allows semantics-based retrieval of distributed mathematical facts.

Problem: Several geoparsers are available, each with their own gazetteer and toponym recognition and resolution approaches. However, they often lack extensibility, implementations are not accessible, or they are fixed to a particular gazetteer. This makes adjustments to other application domains difficult and prevents easy experimental setup. HeidelPlace provides: •A generic gazetteer model sup...

Wikis provide a new way of collaboration and knowledge sharing. Wikis are software that allows users to work collectively on a web-based knowledge base. Wikis are characterised by a sense of anarchism, collaboration, connectivity, organic development and self-healing, and they rely on trust. We list several concerns about applying wikis in professional organisation. After these concerns are met...

Admitting that the quality of a decision depends on the quality of the knowledge used to make it, it is argued that the enhancement of the decision making efficiency and effectiveness is strongly related to the appropriate exploitation of all possible organizational knowledge resources. On the other hand, software is perceived as an encapsulation of knowledge. Especially software tools offering...

Recommendation plays a vital role in adaptive educational systems. Learners often face large body of educational materials including not only texts (explanations), but also interactive content such as exercises and questions. These require various knowledge levels of multiple topics. For effective learning, personalized recommendation of the most appropriate items according to the learner's cur...

The knowledge grid is an intelligent interconnection environment that enables people to effectively manage knowledge resources. To enhance the acquirement and sharing of critical knowledge in knowledge grid, this paper proposes a new knowledge model -memory grid. Memory grid incorporates memory theory of psychology into knowledge grid to deliver plenty of context information. Based on the intel...

This paper presents a proposal for a system capable of retrieval information from the processes generated by the system Yacy. The information retrieved will be used in the generation of a knowledge base. This knowledge base may be used in the generation of semantic web applications.
