We propose a new conceptual model for XML data called XSEM as a combination of several approaches in the area of the conceptual modeling for XML. The model divides the conceptual modeling process of XML data to two levels. On the first level, a designer designs an overall non-hierarchical conceptual schema of a domain. On the second level, he or she derives different hierarchical representation...

Numerous scholars have applied conceptual graphs for explanatory purposes. This study devised the ‘Remedial-Instruction Decisive path (RID path)’ algorithm for diagnosing individual student learning situation. This study focuses on conceptual graphs. According to the concepts learned by students and the weight values of relations among these concepts, this study established the remedial-instruc...

We use Conceptual Graphs (CGs) to model web content extraction rules (CG-Wrappers). The approach presented incorporates all major existing extraction techniques and allows the definition of synergies of cooperative wrappers for handling complex extraction task, without requiring programming.

This paper investigates situating of ubiquitous computing within our current everyday environments. We describe how tying information to actual physical locations can improve the usefulness of ubiquitous computing environments and promote the use of ubiquitous computing services. It is envisioned that these environments will emerge as a social framework for information distribution, and that th...

The paper describes the central ideas of a new approach to creating Web-sites of art museums; it is proposed to take into account the peculiarities of the child’s cognitive-emotional sphere for constructing children-oriented Web-sites of art museums. The idea is that usual Web-sites are created to inform the users, to display the treasures, to show the gems of the collections in order to attrac...

Investments in information technology (IT) do not always result in the expected payoffs. The factors which determine the success of IT investments are not well understood. Event studies are one approach to appraising IT investments. In this paper we review major event studies on IT investments, and based on the results of these studies, we propose a conceptual model describing the factors that ...

The work analyses typical uses of attribute-like relations in conceptual graphs and identifies general sources of failure to convey intended meaning. These include relations that do not contain a semantic bond between their arguments, semantically superfluous concept types, and confusion between first-order and second-order levels. The analysis focuses on the semantics of physical quantities an...
