example 1
[0048] Example 1: O 1 with O 2 For concurrent operation, O 1 for semantic operations, O 2 for the modification operation.
[0049] o 1 :=(SV, ObjID, |COLOR); It is not allowed to modify the color of the object represented by ObjID
[0050] o 2 :=(SV, ObjID, {COLOR, {RED}}); fill the object with red
[0051] due to O 2 The attribute of action is O 1 Modification is not allowed, so O 1 and O 2 conflict.
[0052] b) Semantic compatibility "":
[0053] Given two concurrent operations O 1 and O 2 , at least one of which is a semantic operation. If O 1 and O 2 If it is not a semantic conflict relationship, it is defined as a semantic compatibility relationship.
example 2
[0054] Example 2: If O in Example 1 2 The definition is modified as follows:
[0055] o 2 :=(SV, ObjID, {POSITION, {Value}}); Modify the position of the object, that is, perform a moving operation, then O 1 and O 2 compatible.
[0056] The third step is the implementation of semantic conflict detection and resolution of more than two concurrent operations
[0057] ① When an editing operation conflicts with a semantic operation, the principle of semantic operation priority is adopted, that is, the editing operation is ignored.
[0058] As in example 1, since O 2 For edit operations, it will be ignored.
[0059] ② Define the pairwise relationship of multiple concurrent operations in the form of a matrix. Assuming that there are n operations, the n operations can be defined as an n*n matrix Matrix. If operation i is semantically compatible with operation j, then Matrix[i, j]=. If the semantics of operation i and j conflict, then Matrix[i, j]=.

Abstract
The present invention discloses semantic consistency maintaining method in synergistic pattern design in distributive environment. Through the detection on semantic conflict and compatibility in concurrent operations, semantic compatible group is created, user's negotiation mechanism is provided, the semantic compatible operation group on target is determined through negotiation, and semantic consistency maintenance in the site copies is finally realize. The present invention realizes the detection and solution of semantic conflict problem in multiuser synergistic pattern design to ensure the influent operation in synergistic design and to maintain the semantic consistency in the synergistic edition of different users.
Description
technical field [0001] The invention relates to the technical field of Internet-based distributed pattern collaborative design, in particular to a method for maintaining semantic consistency in pattern collaborative design. Background technique [0002] In recent years, with the deepening of informatization and the integration of communication technology and computer and network technology, computer systems have begun to turn to support the extensive and effective working mode of human beings—collaboration. Computer SupportedCooperative Work (CSCW) is an important research field in computer science. It mainly researches and develops key technologies for the collaborative work of small groups, projects and organizations, including communication, coordination, cooperation and even competition between people. At the same time, CSCW is a product of interdisciplinary integration, including computer science, sociology, anthropology, psychology, organization and economics. Its m...
