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...

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...

Membrane/ protein trafficking in the secretory/ biosynthetic and endocytic pathways is mediated by vesicles. Vesicle trafficking in eukaryotes is regulated by a class of small monomeric GTPases the Rab protein family. Rab proteins represent the largest branch of the Ras superfamily GTPases, and have been concerned in a variety of intracellular vesicle trafficking and different intracellular sig...

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...
