Wikipedia is one of the largest online encyclopedias that exist in a hypertext form. This nature prevents Wikipedia’s potential to be fully discovered. Therefore the focus of this paper is on the role of domain knowledge in supporting the exploration of classical encyclopedic content, which in this case is Wikipedia. A main contribution provided by the author of this work is a methodology for i...

This paper discusses and empirically evaluates the relevance of shopping-related logistics for consumers of store-based retail formats. Based on a literature review a conceptual model was developed and subsequently tested using a survey of more than six hundred consumers in the grocery retail sector. Respondents were those primarily responsible for grocery shopping in their households located i...

The traditional problem of updating relational databases through views is an important practical problem that has attracted much interest. In this paper, we examine the problem of view update in EntityRelationship based database management systems [17] where the conceptual schema is represented by a normal form ER diagram [16] and views may be modelled by ER diagrams. We develop a theory within...

More work is needed on devising practical, but theoretically well-founded procedures for doing object-oriented database (OODB) design [17]. Design procedures should also be flexible enough to take into account various application characteristics (such as whether objects are very large or are read-only). In this paper, we present and discuss an OODB design procedure that addresses these problems...

We define sentence generalization and generalization diagrams as a special sort of conceptual graphs which can be constructed automatically from syntactic parse trees and support semantic classification task. Similarity measure between syntactic parse trees is developed as a generalization operation on the lists of sub-trees of these trees. The diagrams are representation of mapping between the...

We present a methodology to characterize a continuum-scale model of transport in porousmedia on the basis of pore-scale distributions of velocities computed in three-dimensional pore-space images. The methodology is tested against pore-scale simulations of flow and transport for a bead pack and a sandstone sample. We employ a double-continuum approach to describe transport inmobile and immobile...

In Experiment I. two tasks were administered to children aged 4. 5. and 9 111 order to investigate preference for perceptual versus conceptual attributes in grouping of common objects. and in vartous aspects of memory. The grouping task revealed a clear chronological progression: color and form determined the youngest children’s grouping about equally: form dominated in the s-year-olds: and mos...
