網際網路搜尋是很重要的工具，可用以蒐集或尋找資訊。然而搜尋結果有時無法完全符合使用者的原意，所以網際網路搜尋引擎公司致力於發展更好的搜尋演算法，是為了增進搜尋結果的準確性並提高使用者對搜尋引擎的使用率，我們從探討的文獻中發現目前並沒有一個較彈性、開放的工具來評量網路搜尋的效能。本研究的目的就是希望能發展出一個較具彈性的負載量模型以針對網路搜尋進行效能評量。本研究著重在效能評量的負載量模型及測試套組的設計，我們希望透過以學名結構為基礎的方法擴展負載量模型的彈性，我們蒐集及研討幾個具代表性的網路搜尋演算法，並找出這些主要演算法的學名結構，以這些學名結構為基礎進行負載量模型的設計，負載量模型包含網頁模型、查詢模型與控制模型。最後，我們利用雛形實作來驗證本研究所提出的研究方法。 / Web search service is a vital way to find information on the web. However, not every piece of information found is relevant or useful. In order to improve search accuracy, most designers of the web search engines devote to working on search algorithms development and optimization. From literature, we realize that there are few open or flexible performance evaluation methods for web search service. The objective of this research is to develop a more flexible workload model based on generic construct for web search benchmarking and build an automated benchmarking environment of performance evaluation. Generic constructs are major components which can represent the web search algorithm. We collect and review literature related to web search algorithms and benchmarking. And we identify the generic constructs of key web search algorithms. The workload model consists of a page model, query model and control model. The page model describes the web page structure in web search. The query model defines some important criteria to query the web search engines. The control model defines the variables that used to set up the benchmark environment. Finally, we validate the research model through the prototype implementation.

網際網路在許多方面皆改變了大眾的讀報方式：不僅僅是因為Google News一類的新聞搜尋引擎，提供讀者多樣化且一次性的即時整合型閱覽，現今多數的網路使用者，也已養成從數個不同網頁中選擇所需資訊來瀏覽或進行研究、調查的習慣。然而，隨著報紙印刷發行量的銳減、新聞網站的流量不如預期，新聞媒體出版商對於搜尋引擎憑藉他人著作獲取暴利的手法感到越來越挫敗。Google自西元2009年起在Google News美國版刊登廣告，會不會成為壓垮傳統新聞媒體的最後一根稻草?而Google的這項舉措是否動搖其利用他人著作內容賺錢的正當性?可符合美國著作權法的合理使用原則? 本文將就Google News刊登廣告所引發的爭議，從網路新聞的發展、Google的經營模式以及合理使用原則的規範目的等面向，鎖定美國著作權法，來探討網路搜尋引擎截取他人著作內容的合法性，以及數位時代下合理使用原則的未來命運。 / The Internet has changed the way people reading the newspaper: not only because news search engines such as Google News providing readers with a diverse and one-time real-time integration of reading, but also because nowadays, most Web users have become accustomed to selecting the information they need from several different Web pages for browsing or carrying out research, and investigation. However, as the newspapers’ circulation drops, and the flow of news Web sites does not reach the expectation, the fact that search engines use others’ works to obtain profits disappoints news media publishers a lot. Will the advertisements placed alongside search results on the American version of Google News be the last straw? Will this undermine the validity of Google’s initiative of using others’ work for money, and fit in with the fair use doctrine? This article will try to analyze the Google News advertising disputes from the perspectives of development of network newsm, Google's business model and the fair use doctrine , and to discuss the legality of the Web search engine as well as the fate of fair use under digital era in the future.
