Thematic maps in the context of information retrieval are tools that graphically present documents and characterising terms. We investigated the usefulness of thematic maps in a laboratory experiment comparing a thematic map with a command language interface. Six subjects solved eight search tasks producing ten hours of logged and tape-recorded data. The experiment revealed no improvement in th...

Thematic organization of text is a natural practice of humans and a crucial task for today’s vast repositories. Clustering automates this by assessing the similarity between texts and organizing them accordingly, grouping like ones together and separating those with different topics. Clusters provide a comprehensive logical structure that facilitates exploration, search and interpretation of cu...

Mechanisms for overcoming semantic heterogeneity in diverse information sources are critical components of any interoperable system. In the case of diverse geographic information sources, such mechanisms present particular difficulties since the semantic structure of geographic information cannot be considered independently of its spatial structure. This paper develops an approach to the integr...

compute thematic fit for pairs relying only on distributional information (no information about semantic types) compare thematic fit differences across conditions and processing cost differences (high processing cost → low thematic fit, corresponding to 1-thematic fit in the model) verify if the computational model yields the same main effects and pairwise differences reported by t...

The book has nine chapters plus an introduction and concluding remarks with a foreword by Daniel Nii Aboagye Aryeh (PhD). Its content can be divided into two thematic parts. first part, covering chs. 1–5 (pp. 1–42) is described variously as “elements of biblical interpretation” (p. xv), “foundational principles” “basic elements Biblical Exegesis” 41). authors signal this division indicating in ...

This study deals with the effects of lossy image compression in the visual analysis of remotely sensed images. The experiments consider two factors with interaction: the type of landscape and the degree of lossy compression. Three landscapes and two areas for each landscape (with different homogeneity) have been selected. For every of the six study area, color 1:5000 orthoimages have been submi...
