A Domain-Oriented Approach for GIS Component Selection

Abstract

So far, one of the key non-solved aspects of component-based developments is identifying and recovering existing components in effective way. On these lines, we all agree on the needs of organizing and cataloging candidate components to speed up search and identification. Particularly, domain-oriented catalogues have emerged as promissory tools, although it also implies more complex procedures for their creation. In this context, this paper introduces a proposal to compile information for Geographic Information Systems (GIS). By using Natural Language Processing (NLP) along with a standardized information scheme, we extract and catalogue information from components on the Web as well as from requirements from components' users. We describe the main elements of the process and we illustrate them by using a motivating example.

Domain-oriented information search on the Internet

“…As a result of this research, an information model of domains IM is proposed. In this model, it is assumed that the information space is organized as a hierarchical structure, at the levels of which Web areas containing objects with their attributes are defined [21,22,[24][25][26][27][28]. In other words, the information space (Web space) of the Internet consists of domain areas containing sets of websites servers and other information services, which we will call domain objects.…”

Normalización de información de servicios requeridos para Sistemas de Información Geográficos

“…En este capítulo describimos nuestra propuesta [26], la cual constituye una parte del procedimiento integral construido especialmente para facilitar los procesos de búsqueda y selección de componentes. Así, nuestra propuesta plantea una mejora a dichos procesos consistente en la estandarización de los criterios de búsqueda de componentes.…”
