Service-Oriented Computing promotes building applications by consuming reusable services. However, facing the selection of adequate services for a specific application still is a major challenge. Even with a reduced set of candidate services, the effort on assessing candidates could be overwhelming. We have defined an approach to assist developers in the selection of services, which mainly comprises an assessment process for service Interface Compatibility. This assessment process is based on a comprehensive structural scheme for services' interfaces matching. The scheme allows developers to gain knowledge on likely services' interactions and their required adaptations to achieve a successful integration. We evaluated the performance of the Interface Compatibility analysis with a data-set of 453 services and two different service discovery registries. The experiments shown an improvement of up to 17% in precision and up to 8% in the DCG usefulness metric, with regard to the previous results obtained using only textual (syntactical) queries.

Identification of COTS candidates is a complex activity itself. It implies not only dealing with an impressive number of possible candidates but also with unstructured information that requires a careful analysis. In this context, some proposals currently use description logics to develop an ontology for matching requested and provided services, or propose taxonomies for classification; others suggest extending the identification stage with a learning phase, which provides support to the COTS component discovery process. In this paper, we present common features and differences among some of these proposals, identifying relevant issues for COTS component classification and identification in the near future.

The issues concerning judicial statements focus on the frequency with which they are issued and the manner in which people areor are not -notified. Nowadays, technology offers the justicemedia relationship many opportunities; and electronic notification rises as a common media for communication. However establishing a trustable procedure is not usually easy. In this context, the Court of Neuquén, Argentina, has proposed a pilot project to permit the notification of court documents electronically, in a system that replaces the existing paper filing system. The purpose of the project is to increase the efficiency of serving documents, to decrease cost without hindering transaction safety. To do so, the process schema is supported by a process improvement framework, which includes a well-established electronic signature procedure. In this paper, we describe the electronic notification schema and illustrate with a case study. Discussion is addressed to draw risks and lessons identified when managing the pilot project.
