Predicted tertiary structure showed that thl2 protein possessed a domain , and the srk - binding site cppc is located in tertiary structure surface , which provided the spacial foundation for thl2 binding srk kinase
預(yù)測的thl2蛋白質(zhì)高級結(jié)構(gòu)中有一個結(jié)構(gòu)，并且其與srk結(jié)合的活性位點(diǎn)cppc位于蛋白質(zhì)的表面，這為thl2蛋白與srk激酶結(jié)合提供了空間上的基礎(chǔ)。
In the preprocessing stage the method of user and session identification often adopt heuristic algorithm for the being of cache and agent . this induce the uncertainty of data resource . the cppc algorithm avoid the limitation and has no use for complicated hash data structure . in this algorithm , by constructing a userld - url revelant matrix similar customer groups are discovered by measuring similarity between column vectors and relevant web pages are obtained by measuring similarity between row vectors ; frequent access paths can also be discovered by further processing of the latter . experiments show the effectiveness of the algorithm . in the fourth part , this thesis bring some key techniques of data mining into web usage mining , combine the characteristic of relation database design and implement a web usage mining system wlgms with function of visible . lt can provide the user with decision support , and has good practicability
本文算法避免了這個缺陷，且不需要復(fù)雜的hash數(shù)據(jù)結(jié)構(gòu)，通過構(gòu)造一個userid - uel關(guān)聯(lián)矩陣，對列向量進(jìn)行相似性分析得到相似客戶群體，對行向量進(jìn)行相似性度量獲得相關(guān)web頁面，對后者再進(jìn)一步處理得到頻繁訪問路徑。實(shí)驗(yàn)結(jié)果表明了算法的有效性。第四是本文將傳統(tǒng)數(shù)據(jù)挖掘過程中的各種關(guān)鍵技術(shù)，引入到對web使用信息的挖掘活動中，結(jié)合關(guān)系數(shù)據(jù)庫的特點(diǎn)設(shè)計(jì)并實(shí)現(xiàn)了一個具有可廣西人學(xué)頎士學(xué)位論義視化功能的web使用挖掘系統(tǒng)wlgms 。
