1、WebWeb挖掘關(guān)鍵技術(shù)及研究挖掘關(guān)鍵技術(shù)及研究摘要:摘要:近年來(lái),隨著計(jì)算機(jī)的快速發(fā)展,利用計(jì)算機(jī)從龐大的數(shù)據(jù)中智能地、自動(dòng)地抽取有價(jià)值的知識(shí)模式,以滿足人們不同應(yīng)用的需要。隨著互聯(lián)網(wǎng)的普及和迅猛發(fā)展、Web上信息量的爆炸式增長(zhǎng)網(wǎng)上的資源得到極大豐富但也充斥著大量的垃圾信息人們迫切需要能從這些紛繁蕪雜的信息中找到有用知識(shí)的工具。鑒于數(shù)據(jù)挖掘工具的日益成熟完善人們自然而然想到了要把數(shù)據(jù)挖掘技術(shù)應(yīng)用到Web上來(lái)。Web挖掘指在WWW上挖掘
2、潛在的、有用的模式及隱藏的信息過(guò)程。該文首先概述了數(shù)據(jù)挖掘的概念、挖掘算法及其主要應(yīng)用領(lǐng)域,然后對(duì)Web分類以及方法進(jìn)行了科學(xué)的概述,通過(guò)對(duì)Web內(nèi)容挖掘、Web結(jié)構(gòu)挖掘和Web日志挖掘詳細(xì)分析和對(duì)主要的挖掘算法及最新研究進(jìn)展的綜合表述,最后介紹了Web挖掘的研究方向和發(fā)展趨勢(shì)。關(guān)鍵詞:關(guān)鍵詞:Web挖掘;Web內(nèi)容挖掘;Web結(jié)構(gòu)挖掘;Web日志挖掘;結(jié)構(gòu)算法一、引言..................................
