Embodiment
[0031]This embodiment is based on ProgrammableWeb. ProgrammableWeb is a famous mashup and open API service directory. As of February 2011, more than 5,000 mashups and more than 3,000 API services have been listed, and some registration information of mashup and API services are provided. Include their names, URLs, providers, tags, etc. The mashup is an SOS obtained by combining API services, and the API is a service, so it meets the data requirements of the present invention. For the convenience of implementation, the present invention uses data on the ProgrammableWeb as a carrier to provide embodiments.
[0032] This embodiment includes a service classification step and a service recommendation step, and the specific method is as follows:
[0033] 1. Service classification steps
[0034] A mashup is composed of API services and can be regarded as a large-grained service. To enable automatic classification of services (mashups, APIs):
[0035] Step 3.1, use the web crawlin...

The invention belongs to the technical field of services computing, relates to a service classification and recommendation method based on a bipartite graph and the projection of the bipartite graph. The method comprises a service classification step and a service recommendation step; the service classification step comprises the specific steps: collecting service-oriented software (SOS) information, abstracting a construction relation between the SOS and the service by using the bipartite graph; then projecting the bipartite graph at a SOS dimension to obtain SOS similar graphs, and clustering the SOS similar graphs to obtain the classes of the SOS; the service recommendation step comprises the following specific steps: projecting the bipartite graph at the service dimension to obtain a service combination graph, and analyzing the use mode of the SOS and the service according to the bipartite graphs of the SOS and the service, taking a plurality of services with high operating frequency as the core services, recommending the corresponding service according to different application scenes. The method has the advantages of realizing the automatic classification of the service and adding the classification information for the service, thereby providing convenience for discovering and searching the service and managing the service resources.
Description
technical field [0001] The invention belongs to the technical field of service computing, and in particular relates to a service classification and recommendation method based on a bipartite graph and its projection. Background technique [0002] Service-Oriented Computing (Service-Oriented Computing, SOC) is a new computing model for distributed systems, which brings a lot of convenience to solve the problem of cross-organization agile application integration in distributed heterogeneous environments, and has become one of the hottest topics in the software field. one. SOC advocates the development mode of constructing applications based on services and their combinations, which has led to great changes in the main form, production mode, operation mode and usage mode of the software system. The software system is in an open collaboration composed of software service entities. in the software environment. It is conceivable that future software systems can be dynamically co...
