簡介：探析文獻期刊數(shù)據(jù)庫的檢索及應用策略探析文獻期刊數(shù)據(jù)庫的檢索及應用策略文獻檢索的基本原理是通過對大量的、分散無序的文獻信息進行搜集、加工、組織、存儲，建立各種各樣的檢索系統(tǒng)，并通過一定的方法和手段使存儲與檢索所采用的特征標識匹配，獲得和利用信息源。其可分為手工檢索和計算機檢索兩種。手工檢索是計算機檢索的基礎，計算機檢索是手工檢索的發(fā)展。從檢索原理來講，手檢與機檢并無差別，在檢索進行之前都要進行檢索課題的分析、檢索工具文摘或文檔的選用、根據(jù)檢索課題的要求制定檢索策略、選擇檢索途徑和檢索方法，然后才能進行檢索操作。手工檢索是通過人工自己動手去查找，去對比檢索標識和書本式檢索工具（各種書本式目錄、索引、文摘等）中的存貯標識的相符性，即通過“人書對話”來完成檢索過程。文獻期刊數(shù)據(jù)庫的主要功能概括為信息檢索功能、內(nèi)容擴增功能和服務拓展功能。通過用戶對數(shù)據(jù)庫各項功能的應用情況調(diào)查分析表明用戶已把信息檢索作為使用數(shù)據(jù)庫的主要目的，而數(shù)據(jù)庫新增的內(nèi)容擴增功能和服務拓展功能在用戶實際應用中未能充分發(fā)揮其作用。分析認為，出現(xiàn)這種問題的主要原因，一是用戶沒有真正認識到這些新增功能的作用及巨大的服務優(yōu)勢，二是數(shù)據(jù)庫新增功能模塊還不夠完善、部分鏈接很不穩(wěn)定。1文獻期刊數(shù)據(jù)庫主要功能有文獻期刊數(shù)據(jù)庫主要功能有11信息檢索功能信息檢索功能無論早期開發(fā)的文摘索引庫還是當前發(fā)展較快的全文數(shù)據(jù)庫，人們對信息檢索功能研究歷史較長，構成該功能的軟件模塊技術已相對穩(wěn)定和成熟，內(nèi)容主要包括信息檢索、結(jié)果顯示及下載。在信息檢索方面一般數(shù)據(jù)庫都提供基本檢索（或稱為簡單檢索、快捷檢索等）和高級檢索（或稱專業(yè)檢索、復雜檢索等）功能，并通過二次檢索進一步縮小檢索目標，獲得更準確的結(jié)果；同時，支持邏輯運算、模糊（精確、前方一致）檢索,，提供規(guī)范化詞表和索引瀏覽等檢索方式。在檢索結(jié)果的顯示方面，除對命中文獻提供文獻題名、作者、出處、文摘或全文內(nèi)容外，許多數(shù)據(jù)庫還增加有作者電子信箱、引文等信息。12內(nèi)容擴增功能內(nèi)容擴增功能內(nèi)容擴增功能是數(shù)據(jù)庫在原有基礎上增加的新功能。從傳統(tǒng)數(shù)據(jù)庫概念來看，每個數(shù)據(jù)庫都有對應的文獻收錄范疇，即時間、地域、學科及文獻類型范圍，數(shù)據(jù)庫收錄的文獻內(nèi)容范圍是衡量其質(zhì)量的重要指標。隨著各門學科的深入發(fā)展，交叉性和跨學科文獻愈來愈多，數(shù)據(jù)庫作為文獻信息的動態(tài)集合體，必須打破原收錄的文獻范圍限制，擴增其收錄范圍，網(wǎng)絡技術為數(shù)據(jù)庫的內(nèi)容擴增提供了優(yōu)越的條件。13其他功能其他功能文獻數(shù)據(jù)庫功能的不斷擴充與完善既是數(shù)據(jù)庫開發(fā)商的利益需求，更是廣大用戶對信息服務業(yè)提出的要求。目前，國內(nèi)外著名的數(shù)據(jù)庫都以以上三大功能為開發(fā)信息平臺的主要目標，且不同數(shù)據(jù)庫還有其他一些附加功能。2最大限度發(fā)揮文獻期刊數(shù)據(jù)庫各種功能應采取的主要措施最大限度發(fā)揮文獻期刊數(shù)據(jù)庫各種功能應采取的主要措施21進一步完善數(shù)據(jù)庫的各項新增功能進一步完善數(shù)據(jù)庫的各項新增功能數(shù)據(jù)庫的各項新增功能是近年來國內(nèi)外數(shù)據(jù)庫的發(fā)展方向，但整體而言，各項功能的內(nèi)涵仍然有待充實，與實現(xiàn)使最終用戶無縫鏈接、一步到位的信息服務目標還有很大的距離。22依托數(shù)據(jù)庫的各項新增功能深化圖書館信息服務工作依托數(shù)據(jù)庫的各項新增功能深化圖書館信息服務工作豐富的數(shù)據(jù)庫文獻信息資源構成了圖書館信息服務工作的堅實基礎。同時，通過對數(shù)據(jù)庫新增功能的分析比較和研究，并結(jié)合數(shù)據(jù)庫的其它特征指標，可以全面評估數(shù)據(jù)庫，為文獻資源建設提供科學的決策依據(jù)。23加強用戶培訓工作加強用戶培訓工作數(shù)據(jù)庫資源的使用價值最終要通過用戶的應用來實現(xiàn)，因此，用戶對數(shù)據(jù)庫系統(tǒng)的結(jié)構特點及功能的了解與熟悉程度、對數(shù)據(jù)庫檢索技能的掌握程度都直接影響著數(shù)據(jù)庫功能的發(fā)揮。筆者認為，目前，在數(shù)據(jù)庫用戶培訓方面應從以下3點抓起一是主動與數(shù)據(jù)庫商聯(lián)系，邀請公司人員對本單位用戶進行短期培訓，這也是各商家的用戶培訓任務之一；二是有計劃地組織本單位圖書館人力資源，不拘形式、全方位地開展數(shù)據(jù)庫應用培訓工作。三是結(jié)合本科生、研究生的文獻檢索課教學工作，重點介紹重要數(shù)據(jù)庫系統(tǒng)的結(jié)構特點及增值功能，使其在掌握信息檢索功能的基礎上對其增值功能有一個全面地了解，并能熟練地應用它獲得最多的相關信息和最佳的服務，實現(xiàn)數(shù)據(jù)庫的增值功能。

簡介：論文首頁紙學年第學年第1學期學期課程名稱程名稱傳播學研究理播學研究理論與方法與方法任課教師XX論文題目目“微博微博”在新在新聞傳聞傳播中的作用播中的作用以“新浪微博新浪微博”為例學號學號JNL09053姓名姓名XX年級XXXX級專業(yè)專業(yè)新聞學班級2班提交日期提交日期2010年10月20日成績成績內(nèi)容，充分反映WEB20時代網(wǎng)絡新聞傳播的新格局。閔大洪在其2004年的中國網(wǎng)絡媒體一文中提到“在重大事件和突發(fā)事件發(fā)生時，互聯(lián)網(wǎng)已往往成為受眾的首選媒介?！彼J為網(wǎng)絡輿論的形成主要通過網(wǎng)站以多種形式集中報道，以及網(wǎng)民通過新聞跟貼、論壇上貼等手段來實現(xiàn)的，而主流新聞媒體的適時介入，將會使網(wǎng)絡輿論的影響進一步擴大。謝新洲所著的網(wǎng)絡傳播理論與實踐一書中的第2章第2節(jié)中就重點通過受眾調(diào)查，利用統(tǒng)計方法對網(wǎng)絡受眾理論和網(wǎng)絡傳播效果理論進行了實證研究。當最新事件發(fā)生，網(wǎng)絡媒體可以在獲得相關的文本、圖像、音頻，視頻等信息后立即將之公開發(fā)布。當前的傳媒競爭、主要表觀在新聞的時效性、真實性與報道深廣度的競爭上，與其他媒體相比，網(wǎng)絡在這方面無疑具有更大的優(yōu)勢。三、關于“新浪微博”的研究據(jù)最新門戶微博研究報告，新浪微博依然遙遙領先。其關注度、熱門事件數(shù)量依然讓其它3大門戶網(wǎng)站只能望其項背。新浪微博副總編輯透露，新浪微博自2009年8月14日正式上線內(nèi)測，“用戶數(shù)以每周50的速度增長”。人民日報的評微博彭蘭使人與信息融合胡泳即時網(wǎng)絡一文中，中國人民大學新聞學院教授彭蘭認為，微博正在推動人與信息的融合?！靶畔⒄谧兂扇说牧硪环N存在方式，人的身份、人的思維與人的行為都正在被信息化，人的社會關系也在信息化?！泵喜ㄔ谄湫吕宋⒉┮粓稣诎l(fā)生的信息傳播變革一文中說明，新浪微博可以通過互聯(lián)網(wǎng)、MSN、客戶端發(fā)布，更可以通過手機發(fā)布，實現(xiàn)了全息發(fā)布方式，真正實現(xiàn)了隨時隨地發(fā)布和接收信息。他認為，新浪微博是獨家信息發(fā)布的最好平臺之一。新浪微博從某種意義上講就是“永不閉幕的新聞發(fā)布會”。新聞發(fā)布會是發(fā)布信息的地方，而新聞發(fā)生地，則是指新浪微博本身的變動就是值得報道的新聞。這充分證明了麥克盧漢的觀點“媒介即信息”。譚翊飛的微博的力量一文中提出，微博讓新聞更接近真實，同時微博也可以成為一個同人聚集的“場所”，讀書、思考，對現(xiàn)實問題進行分析、發(fā)表觀點。只有你有自己的癖好，你一定能在微博上找到同樣的希奇古怪的癖好者，因為微博就是整個世界。綜上所述，隨著科技的發(fā)展，大眾傳播媒介同時也在與日俱進。當今時代，網(wǎng)絡傳播已經(jīng)成為了最有潛力的媒介之一。而當前最具代表性的微博勢必將代表著未來傳媒發(fā)展的潮流，隨著技術的進步，人們思想的開放，微博在新聞傳播中的作用扮演著越來越重要的作用，它以手機為主要載體，將在未來實現(xiàn)“一機在手，天下我曉”。
