摘要:本文在介紹簡(jiǎn)易信息聚合技術(shù)(RSS)的含義和功能的基礎(chǔ)上,利用RSS的信息聚合和信息推送兩大基本功能,重點(diǎn)介紹和分析了基于RSS技術(shù)的個(gè)性化檢索在圖書(shū)館中的應(yīng)用。

Abstract:
Based on a description 0f the connotation and functions of RSS,this article introduces and analyzes the application of personality searching base on RSS in the library from information aggregation of RSS and

聚合新聞或者像新聞一樣更新比較頻繁的網(wǎng)站內(nèi)容。它就是某些內(nèi)容的快照(Snapshot)。使用者可以不必打開(kāi)該網(wǎng)站就可以獲得最近更新的內(nèi)容。另外RSS的分類還可以為讀者集中提供他們感興趣的內(nèi)容,從而減少了檢索所花費(fèi)的時(shí)間。
基于RSS技術(shù)的個(gè)性化檢索在圖書(shū)館中的應(yīng)用
  基于RSS技術(shù)的個(gè)性化檢索服務(wù)的個(gè)性化并非個(gè)人化,而是按照物以類聚、人以群分的原理,考慮讀者所屬的特征人群,參考與讀者有相同愛(ài)好、興趣及同行的選擇;赗SS技術(shù)的個(gè)性化檢索,操作簡(jiǎn)單,在支持普通搜索的同時(shí),會(huì)提示與讀者搜索內(nèi)容相關(guān)關(guān)鍵詞并且讀者可以很方便的直接從搜索結(jié)果中訂閱相關(guān)內(nèi)容的RSS。

  信息發(fā)布者按照RSS規(guī)范的要求,形成的RSS文檔具有統(tǒng)一的格式,例如,信息發(fā)布者生成的某個(gè)RSS文檔的源代碼可以為:

信息發(fā)布者生成RSS文檔后,加入到RSS的提要數(shù)據(jù)庫(kù)中,當(dāng)讀者檢索時(shí),服務(wù)器會(huì)自動(dòng)生成RSS格式的*ML文檔并發(fā)送給讀者,讀者可以通過(guò)應(yīng)用程序來(lái)獲取最新的消息概要,如果需要可以根據(jù)LINK元素提供的鏈接去訪問(wèn)。當(dāng)主題內(nèi)容發(fā)生變化時(shí),系統(tǒng)使用更新代理來(lái)完成RSS提要庫(kù)的更新工作,定期搜尋網(wǎng)上更新了的RSS提要(RSS Feeds),并且對(duì)這些提要進(jìn)行分類。<br>3.2信息聚合在圖書(shū)館個(gè)性信息檢索的應(yīng)用<br>  信息聚合和信息推送是RSS的兩大基本功能。RSS具有強(qiáng)大的聚合功能,它可以匯集RSS站點(diǎn)的關(guān)于某一主題內(nèi)容的信息,并統(tǒng)一地推送給讀者,從而避免讀者在各個(gè)站點(diǎn)分別搜索有關(guān)某一主題內(nèi)容的信息而帶來(lái)的費(fèi)時(shí)費(fèi)力問(wèn)題,在一定程度上,它強(qiáng)化了個(gè)性化的服務(wù)功能。與現(xiàn)存的其他信息檢索方式相比,RSS強(qiáng)大的聚合功能和推送功能使得讀者得到的相關(guān)信息更多、更新、更快,在保證讀者問(wèn)題得到滿意解答的同時(shí),還有助于讀者知識(shí)的及時(shí)更新。<br>  對(duì)于圖書(shū)館的個(gè)性信息檢索功能,香港圖書(shū)館協(xié)會(huì)主席兼香港大學(xué)醫(yī)學(xué)圖書(shū)館主任陳麗業(yè)指出:“有學(xué)生曾說(shuō),上google找資料,往往找到成千上百個(gè)網(wǎng)頁(yè),不知道哪個(gè)才有用,若逐一細(xì)看就十分浪費(fèi)時(shí)間!爆F(xiàn)時(shí)網(wǎng)上資訊爆炸,RSS服務(wù)可以應(yīng)用于讀者感興趣的某一類圖書(shū)的訂閱,讀者通過(guò)使用RSS服務(wù)可以更快捷地了解該領(lǐng)域國(guó)內(nèi)外最新動(dòng)態(tài),而無(wú)需分別查看各個(gè)網(wǎng)站。<br>  利用RSS,圖書(shū)館信息檢索可以提供一站式信息服務(wù)平臺(tái)。在RSS對(duì)信息有效集成的基礎(chǔ)上,讀者只需要通過(guò)一次檢索即只需在第一次使用時(shí)提出具體的請(qǐng)求,在今后的查詢中不必次次發(fā)出請(qǐng)求就可檢索相關(guān)網(wǎng)站所提供的全部信息,并經(jīng)過(guò)過(guò)濾機(jī)制為讀者提供結(jié)果集。這一方面避免了讀者在網(wǎng)上漫無(wú)邊際地尋找,可以節(jié)省寶貴的時(shí)間和上網(wǎng)費(fèi)用;另一方面因無(wú)需查看整個(gè)網(wǎng)站,從而減少無(wú)用信息在網(wǎng)絡(luò)中的傳輸。<br>  同時(shí)RSS有助于對(duì)某些專業(yè)性強(qiáng)的領(lǐng)域進(jìn)行知識(shí)過(guò)濾和積累。例如有一部分博客網(wǎng)站的學(xué)術(shù)性比較強(qiáng),內(nèi)容一般聚焦在某個(gè)主 ……(未完,全文共4465字,當(dāng)前僅顯示2255字,請(qǐng)閱讀下面提示信息。<A class=hands
