The algorithm use access frequency information as well as time information , which suit for large , scale vod environment 算法是基于訪問頻率的,但又結(jié)合了訪問的時(shí)間信息。
In addition , the scanning interval of a replica is variable according to the accessing frequencies of those replicas , which makes dafrm more sensitive to the change of system behaviors Dafrm機(jī)制可以在不增加系統(tǒng)負(fù)載的條件下更加靈敏地實(shí)現(xiàn)對(duì)副本的動(dòng)態(tài)管理,充分發(fā)揮文件副本的性能優(yōu)勢。
In order to reduce access frequency to the ntp time server , and efficiently relieve the over - load situation of server . a time synchronization algorithm based on frequency adjustment in distributed system was proposed . under the same accuracy requirement , 為了降低internet上對(duì)ntp時(shí)間服務(wù)器的訪問頻率,有效緩解時(shí)間服務(wù)器資源負(fù)擔(dān)過重的狀況,提出了一套適用于分布式系統(tǒng)的基于頻率調(diào)節(jié)的時(shí)間同步算法。
This paper brings forward a dynamic group cache mechanism , which fully considers data access frequency , validity and consistency of data , and which reduces the network load and improve the response speed by reducing the distance of data transmission 本文提出的組緩沖機(jī)制,充分考慮了數(shù)據(jù)訪問頻率、數(shù)據(jù)有效性和一致性,將部分?jǐn)?shù)據(jù)緩沖在組內(nèi),減少了查詢時(shí)數(shù)據(jù)傳輸?shù)木嚯x,進(jìn)而減少網(wǎng)絡(luò)通信開銷,提高查詢響應(yīng)速度。
Usage analysis includes straightforward statistics , such as page access frequency , as well as more sophisticated forms of analysis , such as finding the common traversal paths through a web site . web usage mining is the application of data mining techniques to usage logs of large web data repositories in order to produce results that can be used in the design tasks mentioned above 日志數(shù)據(jù)的分析可以通過統(tǒng)計(jì)數(shù)據(jù)的形式,像統(tǒng)計(jì)經(jīng)常被訪問的頁面集、像統(tǒng)計(jì)經(jīng)常需要分析的重要的表格數(shù)據(jù)、像通過網(wǎng)站分析找出一般的訪問路徑模式等,也可以通過數(shù)據(jù)挖掘的思想。
Lwi replacement strategy replaces the lowest weight cache item , and the weight is determined by the following three factors : access frequencies of the cache item ' s projected attributes , access probability of the tuples satisfying cache item predicate on each projected attribute , and latest access time of the cache item 該策略以緩存項(xiàng)投影屬性的訪問頻率、屬性上滿足緩存項(xiàng)條件的數(shù)據(jù)被訪問概率、以及緩存項(xiàng)的最近被訪問的時(shí)間確定權(quán)值,替換權(quán)值最低的項(xiàng)。模擬測試表明,在客戶語義緩存中,該策略具有比傳統(tǒng)lru和lfu策略更好的性能。
It utilizes improved matrix cluster algorithm - - value matrix cluster algorithm to cluster users and web pages . compared with common matrix cluster algorithm , the improved one considers accessing frequency of the web and brings forward a new concept - - the correlative weight value matrix , which is one innovation in this thesis 與普通的矩陣聚類算法相比,權(quán)值矩陣聚類算法將網(wǎng)站訪問頻度作為參數(shù)考慮進(jìn)來提出了一個(gè)新的概念? ?權(quán)值關(guān)聯(lián)矩陣,這是本文的創(chuàng)新點(diǎn)之一,它的優(yōu)點(diǎn)是能夠更準(zhǔn)確的反映網(wǎng)站的訪問情況。
