Problems solved by technology

[0004] Traditional service search is generally stored in a database, and then a full-text index is established to improve query efficiency. Due to the inability to take advantage of the characteristics of combined services, the traditional service query method and efficiency are restricted during the service search process.

Embodiment Construction

[0077] In order to realize the variable granularity indexing mechanism for massive service processes, the present invention defines the formal description of service instances and service combinations, realizes a unified digital signature coding scheme, and designs VSC-Tree (Vector Signature Combination Tree (Vector Digital Signature Combination Tree) data structure, which solves the problem of unified storage and maintenance of atomic services and composite services, and can finally realize efficient retrieval of millions or even tens of millions of atomic services and composite service processes on demand , Maximize reuse, and integrate service non-functional constraints (response time, throughput, price, etc.) to provide users with the best service process.

[0078]The present invention proposes a service process search and reuse method based on a variable granularity index, wherein the variable granularity index is constructed based on a digital signature and a hierarchical...

Abstract

The invention discloses a service process searching and reusing method based on variable granularity indexing. According to the method, a variable granularity indexing mechanism is constructed, operated objects are not confined to a single service rather than service processes of any granularity in the service searching and reusing method based on the constructed variable granularity indexing mechanism; and simultaneously, operation units of automatic service combinations can effectively use former edited combined service process segments which can be called, repeated service combination verification, matching and debugging processes are omitted, most appropriate segments are selected from a great number of service process instant segments directly, networked software with large granularity and meeting complicated requirements of users is combined rapidly, and the actual executable degree of automatic service combination results is improved in turn, and the virtuous cycle is formed finally.

Description

technical field [0001] The invention belongs to the field of service computing, and in particular relates to a method for searching and reusing a service process based on a variable granularity index. Background technique [0002] As a standard, cross-platform general model, Web service has become an important part of the development of networked software. Service composition is the process of combining relatively independent and simple atomic services into large-grained services with new functions through the mutual communication and cooperation between basic Web services, so as to generate "value-added" services that meet the higher needs of service requesters. . According to the needs of users, this technology of recombining a single Web service or even a service that has been successfully combined in the past as a component according to certain rules and models has become a research hotspot in future networked software. It can greatly improve the atomic service and serv...
