In this paper a conceptual model for e-learning, which uses elements from learning Objects and Concepts Maps, is introduced. The learning material is divided into atomic units and organized in graphs called Knowledge Map, Learning Map and Student Map. Such a structure provides an easy-to-use navigation interface for existing learning material. Any course content created is stored in a repositor...

In this paper, an idea for integrating research in information retrieval and scientific communication in LIS is proposed. This idea is based on the generation and use of subject maps for documents in a specific domain. A subject map, as defined in this paper, is a kind of representation of the important subjects in the target domain and their mutual conceptual relationships, on a two-dimensiona...

This paper introduces an algorithm for automatically acquiring the conceptual structure of each word from corpus. The concept of a word is defined within the probabilistic framework. A variation of Belief Net named as Collocation Map is used to compute the probabilities. The Belief Net captures the conditional independences of words, which is obtained from the cooccurrence relations. The comput...

Recently, a number of authors [KS, Oh2, Ro] have independently shown that the universal finite type invariant of rational homology 3-spheres on the level of sl2 can be recovered from the Reshetikhin-Turaev sl2 invariant. An important role in Ohtsuki’s proof [Oh3] plays a map j1 (which joins the legs of 2-legged chinese characters) and its relation to a map α in terms of a power series (on the l...

High-level semantics such as “mood” and “usage” are very useful in music retrieval and recommendation but they are normally hard to acquire. Can we predict them from a cloud of social tags? We propose a semantic identification and reasoning method: Given a music taxonomy system, we map it to an ontology’s terminology, map its finite set of terms to the ontology’s assertional axioms, and then ma...

In this article, we study the emergence of associations between words and concepts using the self-organizing map. In particular, we explore the meaning negotiations among communicating agents. The self-organizing map is used as a model of an agent’s conceptual memory. The concepts are not explicitly given but they are learned by the agent in an unsupervised manner. Concepts are viewed as areas ...

Many topics in integrable surface geometry may be unified by application of the highly developed theory of harmonic maps of surfaces into (pseudo-)Riemannian symmetric spaces. On the one hand, such harmonic maps comprise an integrable system with spectral deformations, algebro-geometric solutions and dressing actions of loop groups generated by Bäcklund transforms [5], [6], [14], [21], [24]. On...

In this paper we describe an interface for searching and conceptualizing related information. We describe a specific application of this interface for searching traditional artists in the state of Indiana. The interface employs multi-modal interaction by allowing the user to search for artists using a map of the state of Indiana alongside a conceptual hierarchical map of crafts and sub-crafts. ...

in this paper, geographical information system (gis) is used as a support system for decision making in order to provide the map of high potential areas for the construction of greenhouses benefited from geothermal energy. the goal is to perform a geothermal energy resource assessment in eastern azerbaijan province as a base for further studies to achieve sustainable development objectives in t...
