Embodiment

[0078] The specific program implementation includes, see the appendix figure 1 Shown:

[0079] S1 OML vocabulary acquisition: extract effective information in the text and map it to the concept concept;

[0080] RUCM is a set of use case modeling language, and its metamodel is defined by Ecore language. For example, the "Actor" element is defined by Elass in Ecore, and the "name" attribute in the "Actor" element is defined by EAttribute in Ecore. OML vocabulary is transformed based on the metamodel level. Therefore, the valid information in the text includes: the Ecore category to which the element belongs; the name of the element. Obtain effective information through Ecore API, and then map to the concept concept. The mapping is organized as follows:

Abstract

The invention discloses a method for expressing RUCM by OML, which comprises the following steps: 1, determining elements to be converted and relationships according to relationships among RUCM modeling elements; 2, formulating a mapping rule between the RUCM and the OML in the step (1) according to the OML modeling elements, and forming an oml vocabulary of the RUCM; and 3, reading the text instance of the RUCM, calling the vocabulary in the step 2, and outputting the corresponding OML text instance. The method is used for meeting the requirement for knowledge sharing in the prior art. Automatic conversion from RUCM instances to OML instances is achieved, and the efficiency of a demand stage in industrial design is improved; manpower participation in the conversion process is omitted, andthe data processing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of model conversion processing, and in particular relates to a method for expressing RUCM from OML. Background technique [0002] RUCM is a modeling tool for use cases. Although many requirements specification techniques exist, these tend to fall at the very end of the spectrum in terms of form, that is, they are either fully formal or fully informal. Use case modeling is one of the most widely used structured specification techniques. By combining diagrams and textual descriptions, UML use-case models provide a very intuitive and precise basis for requirements specification. Based on this, a Restricted Use-Case Modeling (RUCM) technique is designed, which includes a use-case template and 26 restriction rules for textual UCSs. The goal of RUCM is ease of use, reducing ambiguity, and improving understanding. It can convert natural language sentences, and it has 108 elements. [0003] OML is a description ...
