Thus, the users realize the fluent operation of synergistic design, and semantic conflict in the synergistic edition of different users is prevented.

Description

Based on the semantic keeping method in the collaborative design of semantic lock realization pattern

Technical field

The present invention relates to distributed pattern collaborative design technical field, particularly relate to a kind of based on the semantic keeping method in the collaborative design of semantic lock realization pattern based on the Internet.

Background technology

In recent years, along with the propelling of the computer technology and the network communications technology, the especially develop rapidly of Internet and multi-media network, computer system has begun to turn to the human extensive and effective mode of operation of support---and collaborative.CSCW (computer supported cooperative work) technology has fundamentally changed traditional working method and the life style of people, and will greatly improve the whole efficiency of people's collaborative work.Nowadays, CSCW progressively is penetrated into growing field, and wherein the collaborative design of pattern is exactly an important application of distributed collaboration system.Distributed real-time pattern collaborative design system makes a plurality of users to edit same width of cloth pattern simultaneously on different geographic position by computer network, thereby finishes the design of patterns task at faster speed.

The architecture that extensively adopts in the various cooperative operation systems comprises three kinds in concentrating structure, replicated architecture and mixed structure.In order to make collaborative design system have the characteristics of quick response user operation, tend to adopt replicated architecture in the pattern collaborative design.Carry out immediately operate in operation promoter this locality relevant with design, is broadcast to other subsequently and participates in each collaborative website.Under this architecture, just there is the semantic maintenance problem of site operation in the copy that each website is preserved.

The semantic maintenance is collaborative problem that does not solve as yet of pattern design field very perfectly.Its objective is the efficient that improves collaborative work by understanding to user's operational semantics.Each user operation must comprise the specific design idea of user, i.e. operational semantics, and it is only to express by the coherence method of safeguarding the pattern document.Semantic maintenance will provide expression, transmission, triggering and the maintenance of semantic operation by the analysis to user's operational semantics in the pattern collaborative design.If system can't keep the operational semantics of website effectively, the stage pattern that user A design just may occur is owing to the misunderstanding of user B is modified to the pattern that does not meet user A original meaning.For example, user A has drawn an ellipse (as Fig. 1) earlier, and his operational semantics is to wish that this ellipse object finally is designed to a slice leaf (as Fig. 2).The oval operation of the picture of user A is broadcast to other members of collaborative design group.When user B sees this ellipse in its view, may this ellipse be filled to redness owing to do not understand the design idea of user A, and it is designed to flower.

Be locked in the consistance that is used to keep each site map case document in the distributed pattern collaborative design system usually, coordinate design person's behavior.Lock can be divided into Pessimistic Locking and optimistic lock usually.So-called Pessimistic Locking, a certain moment, a plurality of users had operation temporary to same document areas, only had a user who in advance has this exclusive lock the executive editor to operate.On the contrary, for optimistic locking method, the user can should also wait for the acquisition of lock in the zone by direct control, if finally apply for locking successfully, the user continues editing.Otherwise, wait for that the operation during lock obtains will be by rollback.According to lock-in range, lock can also be divided into object lock and zone lock.Common lock only can play the consistency maintenance of document content from the grammer angle, and can't realize semantic meaning representation, transmission and the maintenance of site users operation.And the domestic and international so far effective ways that propose to keep distributed pattern collaborative design semanteme as yet.

Summary of the invention

The object of the present invention is to provide a kind of based on the semantic keeping method in the collaborative design of semantic lock realization pattern.

The technical scheme that the present invention solves its technical matters employing is as follows:

1) the semantic meaning representation mode is segmented

The operational semantics of user's design is subdivided into following three kinds:

A) based on the notes and commentary of special symbol and natural language

B) forward to operand or area attribute limits

C) to the reverse qualification of operand or area attribute

2) semantic lock definition

Lock is as a kind of specific operation.User's operational semantics incorporates latching operation, and semantic lock is decomposed into object semantic lock and regional semantic lock,

Semantic lock is expressed as follows:

SL：＝(SV，ObjID/Pos_Region，<[Comment]，[(M_Attrib1[，{ValueRange}])，[(M_Attrib2[，{Value?Range}])]，…，|[NM_Attrib1]，[NM_Attrib2]]，…>))

SV: the state vector of semantic lock operation, demarcate the time that semantic lock takes place

ObjID: object identity, if object lock

Pos_ReGIon: the lock regional location, if the zone lock

Comment: the notes and commentary that lock is semantic

M_Attrib: the attribute-name that forward limits

Value Range: the attribute-value ranges that forward limits

NM_Attrib: the attribute-name of reverse qualification

3) the semantic realization that keeps of editing operation

The first step, according to the area dividing method of pattern document, the operating right of a plurality of users of collaborative design to pattern participated in definition;

In second step, the user sets semantic notes and commentary, specifies lock object or zone, or sets association attributes restriction tabulation;

In the 3rd step, determine to have the object that semantic lock acts on or the user of region operation power automatically and organize UG;

In the 4th step, send semantic lock to UG;

In the 5th step, at the website that receives semantic lock, system carries out semanteme according to semantic lock and keeps handling.

The present invention compares with background technology, and the useful effect that has is:

To be system carry out semanteme to traditional locks to its major function of the present invention expands, and respectively with the attribute in the semanteme notes and commentary of editing operation and lock object or zone just, the mode of reverse qualification realizes semantic non-imposed maintenance and mandatory maintenance.By this semantic lock, system can be to a certain extent effectively assisting users avoid producing the operation of running counter to other collaborative design person's semantemes, make collaborative design more natural and tripping.

(1) practicality: semantic lock can allow semanteme that the user be sure of its pattern editing operation by the collaborative design person who correctly passes to other, through the repetition test proof good practicability is arranged.

(2) preventative: as, to cause too much design to do over again and the waste of design time because of design idea is not clear thereby significantly reduce the user because semantic lock is associated with corresponding edit object or zone in advance.

(3) dirigibility:, when the user understands other devisers' operation intention, can avoid conflict in advance by checking notes and commentary and initiatively consulting with relevant design person because system has adopted mandatory semantic the maintenance and non-imposed semantic the maintenance simultaneously; Or direct edit pattern, the rollback of operating by system when waiting to be intended to conflict.

Description of drawings

Fig. 1 is that user A has drawn an ellipse;

Fig. 2 is that the intention (or semantic) of user A is to wish design a slice greenery.

Embodiment

When the distributed pattern collaborative design technology of implementing based on internet (the Internet), will utilize semantic lock to realize the maintenance of user's operational semantics.

Relate to relevant symbolic interpretation in the method:

Matrix: the authority bivariate table in user, exercisable pattern view zone

AUG: all participate in the online user's of collaborative design set

UG: the user's set that certain semantic operation related object is had operation power

⌒: intersection of sets computing

: empty set

∈: " subordinate " relation between element and the set

Utilize semantic lock to realize that the detailed process of user's operational semantics maintenance is as follows:

The first step, according to the area dividing method of pattern document, the operation power of a plurality of users of collaborative design to pattern is participated in definition, forms the authority bivariate table Matrix of user, operating area.The user organizes AUG={U ₁, U ₂..., U _nCorresponding zone group RG={R ₁, R ₂..., R _n, R wherein _iWith R _jRelation may be following three kinds: R _i⌒ R _j=; R _i=R _jR _i⌒ R _j=R _s, R _s≠ .

In second step, the user sets semantic notes and commentary Comment, specifies lock object or zone, or sets association attributes restriction tabulation { { [M_Attrib ₁, Value Range}] ..., [M_Attrib _n, Value Range}] | NM_Attrib ₁..., NM_Attrib _n.For example, the user has drawn an ellipse, wishes it is designed to a slice leaf.Semantic lock can be with following several formal representations.

SO:=(ObjID, " draw a green leaf "); Notes and commentary

SO:=(ObjID, COLOR, GREEN}); The color that forward limits oval object is necessary for green

SO:=(ObjID, | COLOR); The color of the oval object of reverse qualification does not allow to be revised by other collaborative design persons

The semantic lock operation also can be the combination of above expression-form, as:

SO:=(ObjID, " draw a green leaf ", COLOR, GREEN}|POSITION); The semantic operation promoter wishes that the ellipse of ObjID representative is designed to a slice leaf, and color is green, and the position attribution of object does not allow to be revised by other collaborative design person.

In the 3rd step,, search the user who comprises O or R affiliated area among the Matrix and organize UG according to the position of lock object O or region R.Draw example as institute in second step, the oval object The corresponding area of ObjID representative is searched by system in ARG, and generates these area relative child user groups UG, and satisfies: if u _i∈ UG, then u _i∈ AUG.

In the 4th step, send the semantic lock operation to UG with the multicast form.

In the 5th step, at the website that receives semantic lock, system carries out semanteme according to semantic lock and keeps handling.

If semantic lock only comprises semantic notes and commentary, then show this notes and commentary with window form, carry out non-imposed semantic protection, realize the multiple users share lock function.Draw example as the second step institute, when receiving end collaborative design person clicks the oval object of ObjID representative, system prompt " draw a green leaf ".Collaborative design person just can understand this object initial designs person's design idea in advance before this ellipse object being done other operations.

If semantic lock comprises forward or reverse attributes defining, then run counter to the semanteme that semantic lock limits when this semantic lock receiving end user's editing operation, system is with the form prompting of warning window.As second example that the step draws, if collaborative design person is filled to redness with this ellipse, then this object of system prompt can only be filled to green, and this object initial designs person's design idea has been run counter in user's fill color operation.This operation of collaborative design person subsequently will being forced to property rollback, i.e. automatic Undo operation by system realizes limited lock function, thereby keeps the operational semantics of this object.
