Interactive service establishing method based on service relation body

Abstract

A method for setting up interactive service based on service relation body includes analyzing input parameter semantics in service request after user service request is received, confirming service subject according to analyzed semantics, confirming candidate service in service relation body according to confirmed service subject, returning matched candidate service result and service-ending confirmation to user, using selected candidate service as new service request to return to starting up step if candidate service is selected by user and ending service setting-up process if ending service is selected by user.

Description

technical field [0001] The invention relates to a service creation method for synthesizing existing network services, in particular to an interactive service creation method based on a service relation ontology. Background technique [0002] With the development of the Internet, Web service, as an open service provision method, has been widely recognized by the industry and academia. However, the function of a single Web service is limited, and it is difficult to meet the requirements of users. Therefore, combining existing Web services and generating complex services has become a current research hotspot. Current Web service provisioning methods include user-interactive service generation methods (see: Sirin, E.; Parsia, B.; Hendler, J. Filtering and Selecting Semantic Web Services with Interactive Composition Techniques. Intelligent Systems, IEEE, Volume 19, Issue 4, Jul-Aug2004, 42-49), the above method uses the service matching algorithm to recommend the matching succes...

Problems solved by technology

However, users need to set complex QoS parameters, which is very complicated for users, and often a large number of subsequent services are functionally irrelevant, and according to QoS filtering, only the non-functional attributes of services are considered, and the functions of services cannot be adjusted. control

For example, after the queryAddress service, its output is address, and all services whose input is address are called candidate services, such as querying nearby hospitals, querying nearby schools, querying nearby government agencies, etc. The input of these services is address, and the user's query is A certain bar address, so may not be interested in these services

In addition, although the service interface matching method has the characteristics of automation, that is, from the output parameters of the previous step service, the service description can automatically obtain the data association between the matched subsequent service services, but it cannot take other influencing factors of service combination into consideration. Such as user habits and business logic, etc.

These reasons limit the quality of web services provided

[0006] The above interface matching methods are all based on the interface description of the service. These descriptions are static semantic descriptions, but the static description of the service cannot reflect the characteristics of the service when it is running, that is, it cannot grasp the actual concerns of the user, which also leads to The generated service cannot well meet the needs of users, resulting in a decline in QoS
