例句與用法

1. Using attributed graph transformation productions defined on wscg model , the consistency between wscg execution instance and wscg model is guaranteed with a sound formal semantic basis
   Wscg模型的執(zhí)行語義有兩種描述方式，一種是定義在wscg元模型之上的基本的執(zhí)行語義，這是wscg模型進行解釋執(zhí)行的基礎。
2. A similarity measure combining multiple features and layout is also presented . two attributed graph match methods based on local searching and genetic algorithm are proposed to meet the occasions of different applications . ( 3 ) a static image retrieval testing system is designed and implemented
   ( 3 )設計并實現(xiàn)了靜態(tài)圖像檢索實驗原型系統(tǒng)，包括：提出了圖像內容的分層描述模型；設計實現(xiàn)了基于自組織神經(jīng)網(wǎng)絡聚類技術的樹狀多特征索引結構；提出了一種新的相關反饋模型。
3. Secondly , based on attributed graph grammar theory , we present a meta - model named wscg grammar for wscg model . elements , elements " attributes and elements " relationships of wscg model are all defined in wscg grammar . directed by wscg grammar , a wscg model can be developed , which can satisfy the specification of wscg model and eliminate some structure errors
   其次，基于屬性圖文法，本文給出了由wscg文法描述的web服務復合元模型，對wscg模型的設計過程進行約束，形成一種以屬性圖文法導向的wscg模型設計方式；不但保證了用戶可以生成符合規(guī)范的wscg模型，而且消除了wscg模型在結構上可能引發(fā)死鎖的部分原因。
4. Firstly , wscg ( web service composition graph ) model , a model for web service composition , is proposed , which consists of visual presentation model and executable model . according to this model , the interactions and execution sequences among web services are characterized by wscg nodes and edges and their attributes . based on attributed graph theory , we give the formal definition of wscg model
   本文首先提出了一個基于屬性圖理論的web服務復合模型? ? wscg模型，改進了現(xiàn)有web服務復合模型在可視化表示能力和執(zhí)行語義的確定性等方面的不足；模型包括web服務復合的可視化表示模型和執(zhí)行模型兩個方面。
