3 . some basic algorithms are involved during the studying system framework , including regionalism algorithm , region locating algorithm and multi - region topological structure merging algorithm . the feasibility of 3 、研究系統(tǒng)框架中所涉及到的各種基礎(chǔ)算法,有區(qū)域劃分算法、區(qū)域查找算法和多區(qū)域拓?fù)浣Y(jié)構(gòu)拼接算法。
It then briefly introduces the key techniques , such as xml ( s ) , rdf ( s ) , ontology , owl etc . we specially analyze the role of ontology in semantic web , and discuss the comparison algorithms between different version of ontology , and also , the merging algorithms of ontology from different sources . we have made some essential improvement to the algorithms , and also put forward a notation method to the integration of wsdl and ontology . we have applied our research to the uddi workflow and satisfactorily solved the many problems of traditional keyword - based searching method of uddi 其中對(duì)本體和語義web的關(guān)系做了重點(diǎn)分析;接下來,我們討論了不同版本間本體的比較算法,以及不同來源本體的合并算法,并嘗試著做了一定的改進(jìn);然后,由于wsdl語言的缺乏語義,我們給出了一種注釋的方法,從而將wsdl與具有語義的本體結(jié)合起來;針對(duì)uddi僅能基于關(guān)鍵字來搜索的弱點(diǎn),本文最后還討論了如何將前面所分析的本體匹配算法和web服務(wù)描述的語義化方法應(yīng)用于uddi的工作流程,并給出了一個(gè)dumf框架,在一定程度上提高了uddi的語義層次。
For detecting - analyzing method based on snapshot difference , we implement these snapshot differential algorithm : sort merge algorithm , partition hash algorithm and window algorithm . for detecting - analyzing method based on log , we discuss the analyzing method of log on two relation database systems - oracle and sql server 對(duì)基于快照差分的檢測(cè)分析方法,我們實(shí)現(xiàn)了三種快照差分算法: sortmefge算法、 partitionhash算法和wndow算法;對(duì)基于日志的檢測(cè)分析方法,討論了oracle和sqlserver兩種關(guān)系數(shù)據(jù)庫(kù)的日志分析方法。
In this paper , commonly solution for router alias problem is described . on the basis of analyzing of the key technique , a router alias discovery and merging algorithm is proposed . the algorithm is based on the protocols of network and analysis with the data . in this way , our algorithm transforms the set of interfaces into a set of routers which reflects the real connectivity of routers . with the algorithm the accuracy and the integrity in router discovering are improved 描述了現(xiàn)行的路由器接口解決方法,在對(duì)關(guān)鍵技術(shù)進(jìn)行了分析的基礎(chǔ)上,提出了并實(shí)現(xiàn)了一種路由器別名解析歸并算法,該算法通過對(duì)協(xié)議進(jìn)行分析,綜合數(shù)據(jù)融合技術(shù),將路由器的接口地址集合轉(zhuǎn)換為能夠反映實(shí)際網(wǎng)絡(luò)狀況的路由器集合,從而較好地提高了路由器探測(cè)的準(zhǔn)確性和完整性。
