Most Service Delivery organizations do not have a consistent view of the evolution of the technician skills because in a dynamic environment the creation and maintenance of a skill model is a difficult task, especially in light of privacy regulations, changing service catalogs and worker turnover. In addition, as services expand, new technical support groups for the same type of services are created and also new technicians may be added, either into a new group or into existing groups. To tackle this problem we evolve a method for ranking technicians on their expected performance according to their suitability for receiving the assignment of a service request. This method makes use of similarities between the technicians and previous tasks performed by them. We propose a strategy for incorporating new technicians and delivery team reorganizations into the method and we present experimental results demonstrating the efficacy of the strategy. Applying this strategy to new teams yields on average acceptable accuracy within 4 hours, though with a wide variation across teams for the first 12 hours. Accuracy and its variability approach the quality of accuracy on older teams over 24 hours.

We present an integrated architecture and a particular implementation that combines the use of existing grammar- and rule-based schema languages that allows providers to specify rules in a declarative manner. The integrated architecture provides a way to semi-automatically fill in form fields by calling the proposed service, which enumerates domains from the previously stored data validation constraints. Additionally, better error reporting can be achieved by leveraging structure from the rules' definitions. The proposed architecture has been shown to be practical and is in production use by a large organization, successfully fulfilling its role.

We provide a detailed description of the RDF representation developed for OpenWordnet-PT. We highlight our efforts to extend the coverage of our resource and add nominalization relations connecting nouns and verbs. Finally, we present several real-world applications where OpenWordnet-PT was put to use, including a large-scale high-throughput sentiment analysis system.
