Motivated by cognitive lexical models, network-based distributional semantic models (DSMs) were proposed in [Iosif and Potamianos (2013)] and were shown to achieve state-of-the-art performance on semantic similarity tasks. Based on evidence for cognitive organization of concepts based on degree of concreteness, we investigate the performance and organization of network DSMs for abstract vs. con...

We describe a technique for the automated synthesis of new composite web services. Given a set of component services described as abstract bpel4ws processes enriched with semantic annotations, and given a composition requirement, we automatically generate an executable bpel4ws process that, once deployed, is able to interact with the components to satisfy the requirement. We focus in particular...

This paper presents a manual pilot study in cross-linguistic analysis at the predicateargument level. Looking at translation pairs differing in their parts of speech, we find that predicate-argument structure abstracts somewhat from morphosyntactic language idiosyncrasies, but there is still considerable variation in the distribution of semantic material over predicates. We propose an algorithm...
