本研究採用同時法與歷時法二種文獻老化研究方法，進行資訊檢索領域下系統研究及使用者研究二種主題文獻之老化研究，主要研究重點有二，一是資訊檢索領域下，系統研究及使用者研究二種不同主題文獻老化現象之差異性；二是同一主題文獻下，同時法與歷時法二種不同老化研究方法之文獻衰退情形是否一致。 同時法研究是針對現時某一特定文獻之引用參考文獻進行分析，並測得其引用年齡中數。本研究自LISA資料庫取得2006年資訊檢索領域下系統研究及使用者研究二種主題之相關文獻，作為同時法研究樣本，並利用T檢定檢測系統研究及使用者研究二種主題文獻老化現象之差異。在同時法研究結果方面，系統研究及使用者研究二種主題文獻之引用年齡中數分別為7.25歲與7.98歲，系統研究主題文獻同時法老化速度快於使用者研究主題文獻，但差異不大，T檢定結果亦顯示同時法系統研究及使用者研究二種主題文獻之老化速度無顯著差異。 歷時法研究是分析過去某特定期間所發表之文獻，其逐年被引用情形，並計算其被引用半衰期。本研究利用LISA資料庫取得1996年資訊檢索領域下系統研究及使用者研究二種主題之相關文獻，作為歷時法研究樣本，並利用WOS資料庫，取得其自1996年至2006年間逐年被引用情形。在歷時法研究結果方面，系統研究及使用者研究二種主題文獻之被引用半衰期分別為5.12歲與4.99歲，系統研究主題文獻之歷時法老化速度較使用者研究主題文獻稍慢，二者差異不大，T檢定結果亦顯示歷時法系統研究及使用者研究二種主題文獻之老化速度無顯著差異。 在同時法與歷時法二種研究方法比較部份，就文獻老化速度而言，同時法之引用參考文獻數量於高峰期後，呈現顯著文獻衰退現象；而歷時法達到被引用次數最高峰後，則未呈現明顯文獻衰退現象，可知同時法文獻老化速度較歷時法文獻老化速度快。在柯史（K-S）檢測方面，檢測結果發現，不論系統研究主題文獻或使用者研究主題文獻，同時法與歷時法之文獻老化現象皆不一致。 因此，本研究重要研究結論有二：一是資訊檢索領域下，不會因主題不同而有顯著差異；二是資訊檢索領域下，同時法所測得之文獻老化現象與歷時法所測得之文獻老化現象不一致。 / This obsolescence study uses two kinds of aging research methods - synchronous approach and diachrinous approach. Analyze two subjects of systems-centered and users-centered in the information retrieval field. The main emphasis of the research is two. First, under information retrieval field, the differences between systems-centered and user-centered in obsolescence study. Second, the difference between synchronous approach and diachrinous approach’s aging phenomenon in the same subject. Synchronous approach is targeted at the present of a particular literature references and calculated median citation age. This study acquired the information retrieval field of systems-centered and user-centered’s sample in 2006 from LISA database, and tested the difference between systems-centered and user-centered literature aging with using t-test. The result of synchronous approach, median citation age of systems-centered literature is 7.25 years and median citation age of user-centered literature is 7.98 years. So systems-centered literature aging is faster than user-centered literature. But the difference is small. T test results also revealed that difference between systems-centered and user-centered of literature aging has not significantly. Diachrinous approach was to analyze a particular during the past published literature and observed the cited times each year, and finally calculated its half-life. This study acquired the information retrieval field of systems-centered and user-centered’s sample in 1996 from LISA database, and acquired the cited times each year during 1996 to 2006 from WOS database.The result of diachrinous approach, cited half-life of system-centered literatures is 5.12 and cited half-life of user-centered literatures is 4.99 years. So user-centered literature aging was faster than system-centered literatures. But the difference was small. T test results also revealed that difference between the system-centered and user-centered of literature aging has not significantly Synchronous approach and diachrinous approach methods of comparison. By the literature on the aging speed, cited reference numbers of synchronous approach reached peak period, and the literature curve showed significant recession; cited times of diachrinous approach reached a peak, and literature curve were not significantly recession. It revealed that aging speed of synchronous approach was faster than aging speed of diachrinous approach. In the K-S test, the results showed that synchronous approach and diachrinous approach were inconsistent, whether systems-centered literatures or users-centered literatures. Therefore, the important conclusion of this study are two : First, in the information retrieval field, even different subject there will be no significant differences on literature aging phenomenon; Second, under the information retrieval field, synchronous approach and diachrinous approach which measured the aging phenomenon of literature are inconsistent.

近十年內網際網路迅速興起並蓬勃發展，對我們生活的各個層面造成劇烈的影響，並掀起電子商務的熱潮。目前最引人注目的焦點是B2B，利用網路的特性來降低成本，縮短供應鏈，加速產品生命週期。產業已注意到協同商務中之供應網絡管理，並探討企業問之商務管理所需之方法與資訊技術，以尋求新的企業營運模式。在相關發展中，WWW上之商務資料交換，更是目前發展之重點，我們的終極目標是一個跨產業且進入門檻小的全球性交易平台，ebXML因其可能帶來跨產業協同商務之平台架構逐成為產業矚目之對象。 另一個網路所帶來的問題是資訊爆炸。當人們才剛開始享受網路世界的多采多姿，馬上卻又得面臨資訊氾濫的夢魘。如何利用智慧型的方法，提昇搜尋的效率與提高資訊的效果，是我們所關心的。搜尋引擎的演算法發展已到極致，但在搜尋策略的輔助上仍有發展的空間。 本研究回顧電子商務的緣由與發展，提出web service輿ebMXL應用的跨產業網路交易平台，並設計以5W1H的方式儲存專家經驗與策略，透過查詢擴充的機制，達成搜尋策略與結果的改善，並在這個電子商務架構平台的註冊機制與儲存庫(registry/repository)上運作，讓代理人理解企業之需求與期望，進而完成企業間交易夥伴的尋找，以達成動態供應鏈之實現。 關鍵字：XML，ebXML，web service，UDDI，註冊機制與儲存庫，資訊檢索，搜尋策略，5W1H，後設資料 / Starting from the concept of B2B e-commerce in general, the aim of this thesis is to propose and test a method for supporting trading partners' matching, in particulars those who follows ebXML. In the first place, this research presents a study of the areas where XML may have significant contributions. To avoid falling into pitfalls that works in e-commerce have experienced, we ought to understand the evolution of e-commerce so that the target supports can be derived from learned lessons. With these caveats in mind, the next step is to clarify the characteristics and requirements of a generic B2B framework. Base on the aforementioned survey, the framework of ebXML can be clarified, which is considered as the State-of-Art e-business technology. To reach this, this research is to address not only the problem domain and original concepts but also technology requirements. The ebXML architecture as well as relevant initiatives, viz. SOAP, WSDL and UDDI are then examined to search for potential ebXML-based solutions. In a comparison to RosettaNet, ebXML can provide more efficient and effective searches and matches of trading partners on electronic market place. Among others, the author emphasizes the research into a hybrid of ebXML and so-called web based service technologies. To realize this concept, a searching and matching mechanism with aids of expert's strategies based on 5WIH knowledge schema is carried out in this research. Last but not least, 5W1H knowledge schema is applied, another word serves as metadata, to organize and store expert's heuristic and intelligence in so-called strategy base, so that this work can use the expert's strategy for expanding the keywords to refine user queries in the run-time and thus provide a more efficient and effective matching results. Keyword: XML, ebXML, web service, UDDI, registry/repository, information retrieval, searching strategy, 5W1H, metadata

現今由於之前企業併購熱潮，使得企業到底價值多少？企業是否能夠還有前景？這些問題不僅僅是投資者所關心的問題，也同樣是會計師及企業評價者所關心的問題。又現今已邁入知識經濟時代，企業已從過去以土地、廠房、設備等固定資產來產生企業價值，轉而以服務、品牌、專利等無形資產為主要的企業價值時，企業的價值又要如何來估算。而這些問題都一再的顯示出“企業評價”的重要性。 在進行企業評價之前，企業評價模型中之資料項的取得更是關係著最後評價結果的好壞。在企業評價資料項中，可分為財務性及非財務性。財務性資料項由於定義清楚，所以在資料的收集上較非財務性資料容易。但我們發現過往之資料收集方式並不足以應用在企業評價非財務性資料項的收集上，且現行大多採用人工處理資料的方式，不僅耗費大量時間及成本，又因人工輸入而有資料輸入錯誤之風險，使得資料的正確性大幅降低。故本研究提出一自動化擷取年報中企業評價非財務性資料項之方法，希望藉此方法達到簡化資料收集過程，提高資料的正確性。 / Because of the trend of the business combination, now, more and more people concern about “how much value does a business have?” And “does the business still have any perspectives?” This not only get investors’’ interest, but also the accountant and business valuator. Now we already get into a new economy, called knowledge-based economy. When the businesses are not just use fixed asset, such as facility, factory and land to earn money, but also earn their money by providing services, making brand, or sell patents for live, how to measure the business’s real value and what the real value for the business is. These problems all shows that the importance of “Business Valuation.” Before calculate the business value, the most important thing is to collect the data or data category for business valuation. There are two kinds of business valuation data item. One is financial data item; the other is non-financial data item. Because of the financial data item’s clear definition, the data collection process of financial data item is easier than non-financial data item. And the data collection in the past is not fit for today, and now most valuators use manual way to process these data. This way not only wastes the time and money, but also lowers the correctness and raises the risk of mistype during the process of data collection. In this thesis, we propose an approach to automatic extract business valuation data category from annual report by using the technology of data extraction.

近幾年來，有關地理資訊的網頁搜尋越來越受到重視。傳統的網頁搜尋引擎無法反應使用者查詢和網頁文件之間的地理關聯性。在一些情況下，我們希望網路搜尋引擎能夠考慮使用者查詢與網頁文件間的地理相關性，以提升搜尋的準確度。 我們的研究透過包圍矩形模型(Bounding Rectangle Model；BR Model)以搜尋與使用者查詢之地理相關程度較高的網頁文件。 使用者僅需輪入文字的查詢，即能得到相符結果的網頁文件。首先，我們建立一個地名辭典以找出使用者查詢與網頁文件內出現的地名及空間資料，接著我們利用空間資料建立空間索引項(spatial index term)集合，用來表示使用者查詢與網頁文件內的地理範圍，最後再透過使用者查詢與網頁文件的空間索引項集合計算兩者之間的地理相似程度，以找出與使用者查詢有較高地理關聯性的網頁文件。 此篇論文的貢獻在於我們提一套完整資訊檢索模型架構的方法，分析使用者查詢與網頁文件之間的地理關聯性，使用者藉由輸入文字查詢即能得到相符地理關聯性的網頁文件。 / Geographic web search becomes increasingly popular in recent years. Traditional web search engine, such as Google and Yahoo, can not accommodate geographic relevance between user queries and internet documents. Hence, they can not retrieve geographic related information from user queries. However, in many cases, the geographic relevance between user queries and internet documents could enhance the accuracy of this type of searches. In this thesis, we propose a mechanism that uses the Bounding Rectangle Model (BR Model) to retrieve geographic relevant internet documents in response to user queries. Users provide only the conventional input queries (keywords) and our search engine will return the geographic relevant results. Our method can be classified into the following three steps. In the first step, we create a gazetteer and use it to relate the user query’s geographic terms in internet documents. In the next step, we use the spatial data to build a set of spatial index terms that represents the geographic scope of user query and internet documents. And then we use these spatial index terms to calculate degree of geographic similarity between user query and internet documents to identify highly relevant geographic internet documents. We implemented a prototype search engine using our approach. The experiment results show that we can successfully retrieve geographic relevant data through this mechanism and provide more accurate search results.

面對全球資訊網(WWW)應用蓬勃發展，網際網路上充斥著各種類型的資訊資源。而如何有效地管理及檢索這些資料，就成為當前資訊管理的重要課題之一。在發掘資訊時，最常用的便是搜尋引擎，透過比對查詢字串與索引表格(index table)，找出相關的網頁文件，並回傳結果。但因為網頁描述資訊的不足，導致其回覆大量不相關的查詢結果，浪費使用者許多時間。 為了解決上述問題，就資訊搜尋的角度而言，本研究提出以文字開採技術實際分析網頁內容，並將其轉換成維度資訊來描述，再以多維度資料庫方式儲存的架構。做為改進現行資訊檢索的參考架構。 就資訊描述的角度，本研提出採用RDF(Resource Description Framework)來描述網頁Metadata的做法。透過此通用的資料格式來描述網路資源，做為跨領域使用、表達資訊的標準，便於Web應用程式間的溝通。期有效改善現行網際網路資源描述之缺失，大幅提昇搜尋之品質。

隨著GIS的發展，地圖定位成為空間查詢中極為普遍的行為。一般地圖定位大多透過地址來進行，但是在缺乏地址的情況之下，進行地圖上之定位變成極為困難之事。 本論文嘗試對手繪地圖在真實地圖上進行定位，我們提出了一套機制，使用者可以隨意地以手繪方式繪製街道圖與地標，透過我們提出的方法，即可自動地在真實的地圖上進行定位。 論文中，我們使用相鄰街廓中之地標配置與相鄰之交叉路口之地標配置等變數組成的表示法來描述地圖。我們將手繪地圖與真實地圖轉換成這些表示法，並透過字串編輯距離、圖同構等關係來比較手繪地圖與真實地圖之相似度，從而對手繪地圖進行定位。 實作中，我們挑選了幾處真實場景在台北市地圖中進行比對並觀察其結果。系統採用之地標包括政府機構(如派出所、消防隊、區公所等)、學校、醫院等資料。在實驗中，應用這套表示法可成功的定位出使用者所輸入之各場景所在位置。另外，透過控制相似度門檻值，我們可以調整辨識之精確度，不至於錯失可能之定位結果。 / As the widely spread of the GIS applications, map localization becomes one of the most important features in the spatial information retrieval. Normally, map localization is done through street addresses. Without this information, map localization becomes very difficult. In this research, we are trying to do map localization using hand drawing maps. We proposed a mechanism that can localize the user's drawing map in the reference map automatically. Our approaches use the landmark configurations of the adjacent street blocks as well as the landmark configurations of the adjacent street intersections as the descriptors in representing a map. The user's hand drawn maps and the reference maps are converted into these representations. The string editing distances and graph isomorphism are used in determining the similarities between the hand drawn map and the reference map. The map localization can be done by comparing these similarities. We used various real scenes in Taipei City to verify our systems. The landmarks we used including police offices, fire stations, county offices, schools and hospitals, etc. The experimental results shown that our system can localize the user's input successfully. Moreover, by controlling thresholds in similarity analysis, we can adjust the system's accuracy that reduces possibility of miss localizations.

在文件資料庫的查詢處理上，Top-k相似文件查詢主要是協助使用者可以從龐大的文件集合中，檢索出和查詢文件具有高度相關性的文件集合。將資料庫內的文件依據和查詢文件之相似度程度，選擇出相似度最高的前k篇文件回傳給使用者。然而過去集中式資料庫，因其覆蓋性和可擴充性的不足，使得這種排名傾向的文件查詢處理，需耗費大量時間及運算成本。近年來，使用端對端(Peer-to-peer, P2P)架構解決相關的文件檢索問題已成為一種趨勢，但在高度分散式環境下，支援排名傾向的相似文件查詢是困難的，因為缺乏全域資訊和適當的系統協調者。 在本研究中，我們先針對各節點資料庫作分群前處理，並提出一個利用區域切割的作法[1]，將P2P環境劃分成數個子區塊後，建立特徵索引表。因此在查詢處理時，可透過索引表加快挑選出Top-k相似群集的速度，並且確保有適當數量的回傳結果。最後在實驗中，我們提出的方法會與傳統集中式搜尋引擎以及SON-based [1] 做比較，在高度分散式環境下，我們的方法在執行Top-k相似文件查詢時，會比上述兩種作法有較為優異的表現。 / On query processing in a large database, similar top-k documents query is an important mechanism to retrieve the highly correlated document collection with query for users. It ranks documents with a similarity ranking function and reports the k documents with highest similarity. However, the former approach in web searching, i.e., centralized search engines, rises some issues such as lack of coverage and scalability, impact provides rank-based query become a costly operation. Recently, using Peer-to-peer (P2P) architectures to tackle above issues has emerged as a trend of solution, but due to the shortage of global knowledge and some appropriate central coordinators, support rank-based query in highly distributed environment has been difficulty. In this paper, we proposed a framework to solve these problems. First, we performed the local cluster pre-processing on each peer, followed by the zone creation process, forming sub-zones over P2P network, and then constructing the feature index table to improve the performance of selecting similar top-k cluster results. The experiments show that our approach performs similar top-k documents query outperforms than SON-based approach in highly distributed environment.

在本論文中我們提出了一種個人化情緒／情境音樂檢索方法。主要的概念為根據使用者的feedback來找出符合該使用者情緒／情境的音樂在features上所具備的特性，藉此達到個人化的效果。為了更明確表示出音樂的特性，我們利用統計features分布情況的方式來做為音樂的表示法。同時，定義了兩層features自動weighting的方法來決定每個feature在不同情緒／情境下的鑑別度。最後，我們將探討音樂特性與音色對不同的情緒／情境會造成什麼樣的影響，並試著分析音樂與情緒／情境間的關係。 / In this paper, an approach for personalized music retrieval based on emotions / situations is proposed. The main concept is to find out the properties of music that caused the user have emotions / situations responses via the user feedback. And using the user feedback will help us to establish a personalized music retrieval system based on emotions / situations. To represent the music properties clearly, we proposed a new method of music representation based on statistics. And we defined a two-phase features re-weighting method to find out the importance of features in different emotions / situations. At last, we will discuss the influence of music properties and timbre on different emotions / situations, and try to analyze the relationship between the emotions / situations.

顯示器在日常生活中應用廣泛，未來市場發展朝向大尺寸、畫面精緻度兩方面發展，在畫面精緻度方面，目前主要發展技術有二：OLED及量子點，由於OLED尚有產品壽命短、畫面殘影、成本較高等缺點待克服，且在製程上與現今主流LCD相差甚多，因此本研究針對另一可能發展之技術－量子點進行研究，了解產業現況、技術發展趨勢，並給予台灣相關企業建議。 本研究蒐集與專利品質相關的專利量化指標－專利家族規模、申請專利範圍項數、引用專利數、被引用次數及專利年齡，並利用主成分分析法計算專利品質方程式，以針對研究範圍內的專利進行品質排序，並且蒐集專利權人相關市場及專利活動資訊。在專利分析部分將產業區分上、中、下游三區位進行分析，每一產業區位包含重點專利、重要專利權人分析，在中游部分，另進行專利權人研發專利佈局分析，以專利活動程度與專利品質兩軸向衡量市場競爭者之地位。 研究結論首先將總結如何以專利量化指標衡量專利品質，接者以專利分析結果說明量子點顯示技術整體產業發展現況，並歸納台灣企業未來策略。近年投入研究之企業、申請專利數量漸增，但目前尚無企業在此技術領域處於領導者之地位，上游企業的研發方向多是改善LED背光源各波長強度不均的問題，可加強與量子點研發製造商的合作；中游企業需注意韓國廠商大量申請專利所帶來的效果及部分專利權人專利活動程度低，然而握有高品質專利，對其他企業可能造成威脅；下游企業則須思考如何以其他關鍵技術搭配量子點顯示器，研發符合消費者需求之產品。研究最後，針對以專利量化指標進行專利品質分析的過程進行檢討，給予未來研究建議。 / Nowadays displays have wide applications in our daily life, people are looking forward to large size displays and high image performance displays. OLEDs and Quantum dots are the most important technologies which may enhance the image performance. However, OLEDs have some key disadvantages, including the high price, the motion blur and the short lifespan. Therefore, this study focused on Quantum dots. By looking into the industry and realizing the development of Quantum dots, this study gave advice to related companies in Taiwan. To measure the value of patents, we collected five quantifiable indicators of each patent－the patent age, the size of patent family, the amount of claims, forward and backward citations. Then, we calculated the weight of each indicators by Principal Component Analysis（PCA）. As the result, the value of patents were estimated. In the chapter of patent analysis, we classified patents and patentees to the upper, middle and lower stream, each category included the analysis of important patents and patentees. In the middle stream, we also analyzed the patent portfolio, according to two axis－the patent activity and the patent quality proposed by Ernst in 1998. In sum, this study found that companies invested and researched in the industry increasingly; however, there was no company at the leader position. In the upper stream, companies were improving the intensity of different wavelengths in the backlight, cooperating with quantum dot suppliers could be a good strategy for those companies. In the middle stream, Taiwan companies should pay attention on competitors locating in the high patent activity and the low patent activity but high patent quality. In the lower stream, products disposed quantum dots should also fit in needs of customers. Finally, this study reviewed the analysis of patent quantifiable indicators and gave suggestions for the future research.

檔案原是權力的象徵，從古至今，從東方至西方，只有少數人有權力得以使用檔案。而檔案由封閉走向開放，其重要的轉折點是在1794年，由於法國頒布世界第一部檔案法，規定檔案館應實行開放原則。此後，開放國家檔案館的檔案供民眾使用的觀念，也深深影響檔案館營運的方式。因此目前許多現代化的國家，常把檔案開放程度視為是民主化的重要指標。隨著網路通訊技術的發展，對於檔案開放亦產生極大的衝擊。 本研究採用「多重個案法」與「比較研究法」進行研究，首先瞭解美國、英國與澳洲三國國家檔案館檔案在網路上開放情況。並藉由比較研究法，瞭解三國之間的差異性，並且透過描述、解釋、併排、比較的過程，最後進行分析，將比較之結果做一結論，得出具體的建議。 根據研究發現，提出結論如下：一、檔案開放相關法規方面：（一）三國對於個人隱私權均相當注重，但美國則為政府資訊公開重於個人隱私權保護；（二）美、英兩國檔案相關法規針對網路開放檔案有特別之規範，美、英兩國檔案相關法規針對網路開放檔案有特別之規範，澳洲則為沿用原有檔案法規；二、線上參考服務方面：（一）線上參考服務多無專責部門，但仍有專責人員負責；（二）電子郵件、FAQ等非同步線上參考服務，為三國國家檔案館最普遍使用的形式；（三）三國國家檔案館均針對研究者提供特別線上參考服務；三、線上檢索工具方面為（一）三國國家檔案館提供多元化的線上檢索工具；（二）提供電子檔案及檔案內容影像檔已成為三國國家檔案館趨勢；（三）檢索系統的描述規則符合國際標準，有利於未來國際間檔案描述的資源分享與交流；四、線上檔案展覽方面：（一）線上展覽主題皆與館藏特色、社會文化相互結合；（二）線上展覽呈現方式較為傳統，缺乏創新；（三）線上展覽仍需與檔案館相關活動配合，以達最大的成效。 最後針對前述研究結果提出五項建議：一、明確規範檔案開放範圍，以作為我國檔案在網路上開放之依據；二、觀摩國外國家檔案館經驗，加強國內對線上參考服務的概念與認識，並積極推廣線上參考服務；三、建議國內檔案典藏單位，針對研究者提供特別線上參考服務；四、建議國內檔案典藏單位改善線上檢索系統，提供多元化線上檢索工具；五、針對我國檔案典藏單位之館藏特色及社會文化，積極推動線上展覽。
