ONTOLOGY BASED TECHNICAL SKILL SIMILARITY

Online job boards have become a major platform for technical talent procurement and job search. These job portals have given rise to challenging matching and search problems. The core matching or search happens between technical skills of the job requirements and the candidate\u27s profile or keywords. The extensive list of technical skills and its polyonymous nature makes it less effective to perform a direct keyword matching. This results in substandard job matching or search results which misses out a closely matching candidate on account of it not having the exact skills. It is important to use a semantic similarity measure between skills to improve the relevance of the results. This paper proposes a semantic similarity measure between technical skills using a knowledge based approach. The approach builds an ontology using DBpedia and uses it to derive a similarity score. Feature based ontology similarity measures are used to derive a similarity score between two skills. The ontology also helps in resolving a base skill from its multiple representations. The paper discusses implementation of custom ontology, similarity measuring system and performance of the system in comparing technical skills. The proposed approach performs better than the Resumatcher system in finding the similarity between skills. Keywords

For the first time, a working direct urea and direct urine fuel cell has been developed to generate electricity directly from urea or urine

Ultrasonic NDE for Ceramic- and Metal- Matrix Composite Material Characterization

A brief summary of the progress of the research in the internal structural characterization of metal matrix (MMC) and ceramic matrix (CMC) composite materials is presented here. These materials show great potential for improving turbine engine performance by enabling operation at higher temperatures and stresses than now possible [1]. However, the application of these materials requires advances in NDE capability in order to characterize material parameters that are likely to affect performance. Several ultrasonic methods are being developed to characterize the internal structure of these anisotropic, inhomogeneous materials

CTLA-4: From conflict to clinic

CTLA-4 was first identified in 1991 as a second receptor for the T cell costimulation ligand B7. Uncertainties about its biological function plagued the early years after its discovery until 1995, when it was confirmed to be an inhibitor of T cell responses. CTLA-4 has since scored in the clinic as a target for antitumor therapy and as a soluble inhibitor of autoimmunity
