- Description: Most decisions involve a spatial component, though few people realise its significance (Williamson & Wallace, 2006). Recent advances in web-based geographical information systems (GIS) are bringing the spatial component to the forefront. As a result new opportunities are available for getting decision useful information and data into an environment where it can be shared with and accessed by organisations and members of the general public (Geomatic Technologies, 2008). This paper explores the emerging area of web-based GIS and its impact. Barriers which often limit spatial information access and knowledge building are identified. Recent advances in spatial infrastructure are introduced. A potential model for stimulating the dissemination and use of spatial information is presented. Early implementation activities and associated results are detailed. Future work and parallel research focussed on establishing the value and contribution of spatial information to regional planning outcomes are then briefly described. Copyright © 2008 COSI.

- Description: In this paper, we describe a novel schema for a more semantic text mining process which results in more comprehensive decision making activity by decision support systems via providing more effective and accurate textual information. The utility of two semantic lexical resources; Frame Net and Word Net, in extracting required text snippets from unstructured free texts yields a better and more accurate information extraction process to deliver more precise information either to a DSS or to a decision maker. We explain how the usage of these lexical resources could elevate a focused text mining process which could be applied to an information provider system in a decision support paradigm. The preliminary results obtained after a starter experiment show that the hybrid information extraction schema performs well on some semantic failure situations.
