Performance formula-based optimal deployments of multilevel indices for service retrieval.
MetadataShow full item record
AbstractThere are many different index structures for service repositories, such as sequential index, inverted index, and multilevel indices that include three deployments. Different service sets maybe have different characteristics that may affect performance from different aspects. For a given service set, which index structure is the most optimal one? To address these issues, this paper analyses five indexing models and proposes expectation of traversed service count to estimate performance of service retrieval. Based on these expectation formulas, an optimal deployment method can be identified to maximize efficiency of service retrieval. Our experiments first validate correctness of the proposed formulas and then validate the effective of the optimal method.

Adaptive service discovery on service-oriented and spontaneous sensor systemsLiu, Lu; Xu, Jie; Antonopoulos, Nikolaos; Li, Jianxin; Wu, Kaigu; University of Derby (Old City Publishing, 2012-03-06)Natural and man-made disasters can significantly impact both people and environments. Enhanced effect can be achieved through dynamic networking of people, systems and procedures and seamless integration of them to fulfil mission objectives with service-oriented sensor systems. However, the benefits of integration of services will not be realised unless we have a dependable method to discover all required services in dynamic environments. In this paper, we propose an Adaptive and Efficient Peer-to-peer Search (AEPS) approach for dependable service integration on service-oriented architecture based on a number of social behaviour patterns. In the AEPS network, the networked nodes can autonomously support and co-operate with each other in a peer-to-peer (P2P) manner to quickly discover and self-configure any services available on the disaster area and deliver a real-time capability by self-organising themselves in spontaneous groups to provide higher flexibility and adaptability for disaster monitoring and relief.
Service innovation and performance in Mexican service SMEsMaldonado-Guzman, Gonzalo; Garza-Reyes, Jose Arturo; Rocha-Lona, Luis; Kumar, Vikas; Centro de Ciencias Económicas y Administrativas; University of Derby; Instituto Politécnico NacionalESCA Santo Tomás; University of West England (Springer, 2017-08-29)This empirical research investigates the influence of service innovation on the performance of service SMEs, especially within the context of a country with an emerging economy as it is the case of Mexico. Data were collected through a survey instrument designed and distributed among service SMEs in the Aguascalientes state of Mexico to test a hypothesis formulated from the literature review conducted. The instrument was validated using Confirmatory Factor Analysis, Cronbach’s alpha test and the Composite Reliability Index to ensure its reliability. The hypothesis was tested using structural equation modelling (SEM) using an as input 308 valid responses obtained from the survey. In general, the results obtained show that service innovation has a positive and significant effect on the performance of service SMEs. Specific research related to service innovation in service SMEs is limited. This paper therefore fills this research gap by expanding the limited body of knowledge in this field.
