We present an overview of MedSLT, an Open Source platform for developing limited-domain medical speech translation systems. We focus in particular on the speech understanding architecture, which uses grammar-based language models derived using corpus-based specialisation methods from a single linguistically motivated grammar, and summarise the results of two evaluations which investigate the ap...

Uncertainty of system properties (e.g., performance, reliability, security, interoperability, usability, etc.) often hinders the progress of requirements negotiation. Software architecture evaluation techniques enable stakeholders to clarify the uncertainty of system properties. In another hand, software architecture alternatives cannot be evaluated in a thorough way without consideration of di...

Ontology summarization is a very useful technique to help users making sense of ontologies quickly. We have developed a summarization approach that linearly combines a number of criteria, drawn from cognitive science, network topology, and lexical statistics to produce ontology summaries [1]. Motivated by our later findings that the approach, in its current form, binds the criteria so tightly t...

The evaluation of information systems development methodologies is becoming increasingly important. The lack of a commonly acceptable set of criteria for evaluation, however, hinders aggregating knowledge from field studies. Our study attempts to fill the gap. To reduce the effects of subjectivity, we surveyed the opinions of a group (28) of experienced IS researchers. Fifty-one criteria were g...

One of the most promising fields for ambient intelligence is the implementation of intelligent emergency plans. Because the use of drills and living labs cannot reproduce social behaviors, such as panic attacks, that strongly affect these plans, the use of agent-based social simulation provides an approach to evaluate these plans more thoroughly. (1) The hypothesis presented in this paper is th...

Analysis of public behavior plays an important role in crisis management, disaster response, and evacuation planning. Unfortunately, collecting relevant data can be costly and finding meaningful information for analysis is challenging. A growing number of Location-based Social Network services provides time-stamped, geo-located data that opens new opportunities and solutions to a wide range of ...

Emotional intelligence (EI) refers to a set of competencies that are essential features of human social life. Although the neural substrates of EI are virtually unknown, it is well established that the prefrontal cortex (PFC) plays a crucial role in human social-emotional behavior. We studied a unique sample of combat veterans from the Vietnam Head Injury Study, which is a prospective, long-ter...
