This process consists of a combination of top - down, bottom - up, and middle - out techniques of domain decomposition, existing asset analysis, and goal - service modeling
這個過程由域分解、現有資產分析和目標服務建模的自頂向下、自底向上、中間向外技術的聯合組成。 -
The basic idea for hierarchy - based method is that creating and maintaining a tree of clusters and sub - clusters according to some kind of criterion to measure the distance of clusters, the procedure will be sloped until some terminal conditions are satisfied. hierarchical clustering method can be further classified into agglomerative and divisive hierarchical clustering, depending on whether the hierarchical decomposition is formed in a bottom - up or top - down fashion. most hierarchical clustering methods can produce the better results when the clusters are compact or spherical in shape. but they do not perform well if the clusters are any shape or there are outliers. a main reason is that the most hierarchical clustering methods employ medoid - based measurement as distance between clusters
基於層次方法的聚類的基本思想足：根據給定的簇間距離度量準則，構造利維護一棵由簇利子簇形成的聚類樹，直至滿足某個終結條件為止。根據層次分解是自底向上還是自頂向下形成，層次聚類方法可以分為凝聚的（ agglomerative ）和分裂的（ divisive ） 。人多數層次聚類演算法在緊密簇或球形簇結構下能夠產生較好的聚類效果。 -
Top - down domain decomposition process modeling and decomposition, variation - oriented analysis, policy and business rules analysis, and domain specific behavior modeling using grammars and diagrams is conducted in parallel with a bottom - up analysis of existing legacy assets that are candidates for componentization modularization and service exposure
自頂向下的域分解（過程建模和分解，基於變更的分析，方針和業務規則分析，領域特定行為建模（使用語法和圖表） ）是同供組件化（模塊化）和服務公開候選的現有遺留資產的分析并行控制。 -
A couple of techniques from soma service - oriented modeling and architecture method support the " breadth - first " approach well, namely : top - down domain decomposition, bottom - up existing system analysis, and goal - service modeling see the article, " service - oriented modeling and architecture
一些來自面向服務的建模和體系結構方法service - oriented modeling and architecture method ， soma的技術很好地支持「寬度優先」方法，即：自頂向下top - down域分解自底向上bottom - up現有系統分析以及目標-服務建模請參閱文章「
