Towards a Context-Aware Service Directory [chapter]

Christos Doulkeridis, Efstratios Valavanis, Michalis Vazirgiannis
2003 Lecture Notes in Computer Science  
In this paper we propose a context-aware service directory and we investigate the process of service discovery with respect to contextual information.  ...  Context plays an important role in such a scenario, when used to improve existing service discovery mechanisms, by finding the most appropriate service conforming to the search criteria.  ...  Obviously a context-aware service directory would facilitate service discovery and increase its precision.  ...
