Service creation method, computer program product and computer system for implementing that method
View Patent ↗The invention discloses a method ( 100 ) for creating a service based on a request. This method comprises a step of semantically analyzing ( 30 ) a natural-language request, such as one sent ( 20 ) from a mobile telephone or a personal digital assistant ( 150 ). In this manner, the request may be formulated ( 10 ) in natural language, without needing to possess any technical knowledge whatsoever. The semantic analysis ( 30 ) makes it possible to identify ( 35 ) Web service requirements (or specifications). Next, Web services are determined ( 40 ) and sequenced ( 50 ) based on the identified service requirements. A new service is then made available, such as to the user who made the natural-language request.
1. A method for creating a service from a request, comprising:
semantically analyzing a request in natural language;
identifying Web service requirements based on the semantic analysis performed; and
determining and sequencing Web services depending on the identified service requirements,
wherein the step of semantically analyzing the request comprises:
a lexical and semantic analysis,
wherein the step of determining and sequencing is divided into a step of determining Web services and then sequencing the determined web services, and
wherein the step of determining Web services comprises:
identifying characteristics of Web services based on a description of Web services;
comparing at least some of these characteristics with the identified requirements; and
determining Web services based on a result of the comparison.
2. The method of claim 1 , wherein the step of identifying characteristics of Web services comprises, for each of the services:
accessing a description of the Web service; and
identifying characteristics of that service based on the description of that service.
3. The method of claim 2 , wherein the description of the Web service is in WSDL language.
4. The method of claim 1 , wherein the step of identifying characteristics comprises a semantic analysis of the descriptions of Web services.
5. The method of claim 1 , wherein the identified characteristics involve an input and/or an output for each of the determined services.
6. The method of claim 5 , wherein the identified characteristics comprise, for each of the services:
at least two sets, each with at least three fields, wherein:
a first field of one of the sets pertains to an input of the service;
a first field of another set pertains to an output of the service;
a second field of each of the sets pertains to a type of data related to the first field;
a third field of each of the sets pertains to a semantic tag related to the first field; and wherein the composition step further comprises:
a step of a compatibility test involving the three fields of each of the sets.
7. The method of claim 1 , wherein the step of sequencing ( 50 ) comprises:
a compatibility test involving at least one identified characteristic for each of the determined services.
