The modern digital cartography, represented by numerical cartography, digital elevation models (DEM, DTM, DSM), orthoimages or the same like photo textured on DEM, is the metrically correct and highly descriptive system on which integrate any other source of information. These three-dimensional models in dynamic GIS can provide an interesting tool for the environmental and territorial data mana...

An improved statistical model is proposed in this paper for extracting compound words from a text corpus. Traditional terminology extraction methods rely heavily on simple filtering-and-thresholding methods, which are unable to minimize the error counts objectively. Therefore, a method for minimizing the error counts is very desirable. In this paper, an improved statistical model is developed t...

This work analyzes the interactions of small groups of students doing collaborative learning activities in the primary classroom for learning Chinese as a second language. We take the perspective of identifying the characteristics of interactional moves as students interact and negotiate meaning in the computer-mediated collaborative learning (CSCL) environment called GroupScribbles (GS). Much ...

This paper looks at the epistemological foundations of knowledge representations embodied in retrieval languages. It considers questions such as the validity of knowledge representations and their effectiveness for the purposes of retrieval and automation. The knowledge representations it considers are derived from three theories of meaning that have dominated twentieth-century philosophy. The ...
