Mapping and merging of multiple ontologies to produce consistent, coherent and correct merged global ontology is an essential process to enable heterogeneous multi-vendors semantic-based systems to communicate with each other. To generate such a global ontology automatically, the individual ontologies must be free of (all types of) errors. We have observed that the present error classification ...

This research studies freeway ramp merging phenomena under congested traffic situation via a Driving Simulator (DS). The main objectives of this study were to initially develop a traffic simulation, which evaluates the capacity of merging section relevant to the geometric design and the flow condition. Furthermore, to form a pilot system of the DS combined with the simulation, from which the dr...

This A non-linear model of query modifications during a single session of user searching on the Web is evaluated. In addition to a sequential query modification, in which any query may be reformulation of its direct predecessor, the model allows non-linear interpretation of query reformulations: branching, merging, re-merging (merging of earlier branched chains) and non-sequential execution of ...
