利用維基百科及網路相簿從遊記探勘個人化旅遊行程 / Mining personalized trip plan from travelogues using wikipedia and web albums

吳容瑜 Unknown Date (has links)
近幾年國內的自助旅遊風氣逐漸盛行,行前準備對一般人而言必須花費不少時間。我們必須從網路上收集各方資料加以整理,再規劃出理想的行程,所以行程規劃非常耗時。因此,本篇論文研究由網友撰寫的旅遊文章中,利用維基百科和網路相簿作為輔助工具,探勘分析旅遊景點與路線,並根據使用者的需求提供個人化的行程安排,以作為行程規劃之參考。 我們先將遊記標題透過中文斷詞系統進行斷詞,再利用維基百科確認是否為景點名稱。接著我們利用遊記作者權威性與景點重要性之間的相互強化關係來判斷每個景點的重要性。取得景點名稱及其重要性之後,我們利用遊記的文章結構與特性進而判斷遊記中的旅遊路線,由此步驟可得知景點在旅遊路線中的前後關係。此外,我們利用網路相簿中旅遊相片的資訊預估景點停留時間,並且從交通查詢網站取得景點間的交通時間。 系統根據使用者給定的必經景點,推薦使用者符合條件的旅遊路線。接著,根據使用者選定的旅遊路線,考量使用者給定的時間限制、景點開放時間的限制與景點交通時間的限制,排定行程內各景點適合的參訪時間。最後,根據上述步驟的結果,系統便可推薦使用者個人化的行程。 我們以國內知名BBS批踢踢實業坊上的日本旅遊看版內之遊記作為實驗資料來源,並參考維基百科及Flickr網路相簿,實作出個人化的旅遊行程推薦系統。實驗顯示本論文所萃取出的景點名稱,其精確度92%、召回率100%,而景點停留時間與Ground Truth的誤差範圍為3.16%。最後,滿意度評估顯示本論文的推薦系統符合個人化需求。 / Trip planning is an important and time-consuming step for backpackers. Most research focuses on finding the travel sequence from different data sources such as blog, photos and GPS. Although these approaches can recommend some popular travel sequences for a tourist, but tourist’s place preferences and temporal constraints are not considered. In this thesis, we propose an approach for personalized trip planning which takes tourist’s preference and temporal constraint into consideration. In the proposed approach, first the place names are extracted from travelogues with the aid of the Wikipedia. Then the travel sequences are extracted from travelogues. Based on the relationship of mutual reinforcement between the authority of a place and the hub of a travelogue author, the authority of each place is derived. Moreover, the stay time of each place is estimated from the information of travel photos of a web album. Finally, based on the user specified place preference and temporal constraints, this thesis presents the algorithms to arrange a personalized trip for a user. The experiments show that the place name extraction achieves 92% precision and 100% recall. For the estimation of place stay time, the error is 3.16% compared with the ground truth collected from well-known backpacker site.

以流程特性觀點探討資訊科技在企業再生工程之應用

林明德 Unknown Date (has links)
本研究主要目的有二:(一)探討在再生工程中,資訊科技與流程改造作法之搭配與流程特性之關聯;(二)分析流程特性改變的本質,以了解在流程設計時,如何以資訊科技為流程創新的觸發工具。本研究依支援溝通及支援決策的高低程度將資訊科技分為四類:高溝通低決策、低溝通高決策、高溝通高決策、低溝通低決策;流程改造作法則分為三種:水平工作整合、垂直工作整合及工作步驟最佳化。流程特性則有三項:中介程度、合作程度及負荷程度。本研究主要觀點在於,原有流程具有某些流程特性使得企業營運績效不佳。企業可運用資訊科技及某些流程改造作法之搭配,改變流程的特性,而改善原有流程的缺點。   研究結果,提出下列資訊科技與流程改造作法之搭配。   (一)降低流程的中介程度可應用二種方法:(1)應用高溝通低決策的資訊科技,搭配任何流程改造作法。(2)應用高溝通高決策的資訊科技,搭配水平工作整合改造作法。   (二)提高流程的合作程度可應用二種方法:(1)應用高溝通高決策的資訊科技,搭配水平工作整合或工作次序最佳化的改造作法。(2)應用高溝通低決策的資訊科技,搭配垂直工作整合的改造作法。   (三)降低流程的負荷程度可應用的方法為,應用高溝通低決策的資訊科技,搭配任何流程改造的作法。   研究中並發現,企業在應用資訊科技進行流程設計時,可以流程物件(資訊及實體)之流通為思考的重點,這種觀點有助於了解資訊科技在實施再生工程時的潛能。以流程物件的觀點來看本研究中個案公司的作法,可發現許多作法事實上是為使流程物件的流通更為順暢。資訊科技可將實體資訊(如文件、新聞稿)化為電子資訊而高速傳遞及處理,也可改善實體(不含資訊的實體,如零件)流通的路徑,而提高運輸的效率。當流程物件是電子資訊而無法簡化時,即須注意資訊流通的路徑。   以流程物件的觀點來探討,本研究中流程特性是流程物件在流程中流通及處理的情形;流程改造作法是操作流程物件的方法;而資訊科技則是操作流程物件的工具。以操作流程物件的方法配合操作流程物件的工具,即能改變流程物件在流程中流通及處理的情形。

企業流程資訊有機體模式之探討—以某外商工作站直銷與經銷為例

張智為 Unknown Date (has links)
近年來,企業界盛行引進各種企業流程管理模式以檢視企業既有之工作流程,並透過分析工具與建構方法,系統性地評估舊流程並規劃新流程。企業流程的運作績效是評估企業營運成果的重要指標之一。有關企業流程的審視分析,各有不同的方法。其中,企業流程資訊有機體(PWIO)模式,兼具管理與分析的概念與技術,因此本研究採個案研究方式,應用PWIO模式,針對國內一家某外商工作站之直銷與經銷的訂單處理流程,進行分析比較研究。分析結果顯示,個案公司之經銷訂單處理流程比直銷訂單處理流程還要精簡,再加上付出的成本也是前者小於後者,似乎有檢討直銷經營模式之必要。但因該公司實施直接銷售策略時間尚短,再加上直銷也有經銷模式不及的優點,在流程設計上仍有可改善的空間。因此根據本模式,對於個案公司提出幾點建議方案,希望個案公司能據此改善其直銷作業流程,以提升訂單處理績效。另外建議未來研究可以取得直銷及經銷訂單流程所需的各項人力成本,輔以ABC成本分析法來交叉實證PWIO的結果。本研究為國內首次應用PWIO於高科技產業,也再次驗證該模式的可行性,可供學界與業界有興趣的人士參考。 關鍵詞:企業流程資訊有機體、訂單處理流程、個案研究 / Various kinds of process management models have been introduced to the business field to improve company’s existed workflow. Enterprises can use these models to evaluate their old business processes and establish new ones systemically through analytical means and methods. There are all kinds of different analysis models, each with its unique design. Among them, the Process-Wide Information Organism (PWIO) model posses both the management concepts and analytical methods. Therefore, with a case study design, this present study tended to use this model to analyze and compare the order entry processes of its direct and indirect sales models in a worldwide company’s Taiwan branch. The results showed that the indirect order entry process was simpler and more cost-effective than the direct one. Therefore, it seemed that the subject company needed to reexamine its direct order entry process. However, due to the short term implementation of direct order entry process and the pros of direct sales model, the subject company can still adopt the direct business design with some modification. Some suggestions were raised, based on the PWIO model, to improve the direct order entry process of the subject company. In addition, this study also suggested future research could fetch all kinds of manpower cost of order-entry process in direct and indirect sale, coupled with the ABCs of Cost Analysis, to cross-validate the results of PWIO. Being the pioneer research of applying PWIO to high-tech industry, this analysis model was once again being validated. Interested academic and business personage are encouraged to explore this model further. Key words: PWIO, order entry process, case study

曾小玲, Tseng, Hsiao Ling Unknown Date (has links)
電腦資訊的應用至今,使得企業的部門均擁有功能自動化的資訊系統,但是因應科技發展的突飛猛進,通訊工具與網際網路的整合應用,影響了活動的流程,改變了企業組織的角色及其經營的模式。一般的功能資訊系統是支援流程中活動的自動化,但是無法解決也無法判斷流程上的問題,如人力不足需要調度或超過負荷…等各類問題,要再作更大幅度的變革實屬不易,唯有以流程的角度來重新檢視才能突破。 企業流程改造的理論與方法,自提出至今有數拾餘年的期間,其主要的精神在於以「流程」為再造的重心,重新檢討企業的運作方式,以流程導向取代功能導向。本研究因著資訊科技IT的觸媒及成熟與配合,期望藉著個案實務,進行分析與方法探討,導入BPR的方法;經由本研究的探討及研究者的豐富實務經驗,將理論與實務相結合,讓BPR的導入變成'平易近人',讓BPR的方法是容易應用的。 本研究的結論中,提出個案改造後的新流程,其中實現虛擬組織的企業架構,新的營運模式已經開始實現了;並且提供了一個非常明確的個案,說明BPR的推廣與資訊系統自動化的區隔。同時也建議BPR的應用是一個週而復始的「生命週期」,企業應該定期檢視每個流程,重複應用BPR的方法來執行流程的改造。 / With computer science’s development, today almost every business has owned information system to support business’s operations; on the other hand, organizations in the business also have to do something to match up the rapid progress in communication facilities and development of Internet. Normally, Information system’s location is to support automation in operational processes and activities, and it couldn’t point some fundamental problems, for example: the effective dispatch of staff. So, if business wants to do more transformation, it must review the business processes to break current situation. The essence of business process reengineering (BPR) is “reengineering in process”. Substituting for function-oriented thinking, business takes process-oriented thinking to re-verify operational mode. Combining author’s practical experiences and theories in BPR, the study tries to make the use of BPR be friendly, and prove BPR is a good way to proceed. In the concussion of the study shows a new operational process under a virtual business organizational structure and explain the distinction between spread of BPR and automation of information system. In the same time, the study suggests business should regard BPR as a iterative application with its lifecycle, re-verify business process regularly, and take BPR at the right moment.

設計與實作工作流程引擎之剖面導向擴充機制 / Enhancing Workflow Engines with Aspectual Processes

鍾政憲, Chung,Cheng Hsien Unknown Date (has links)
根據應用系統的功能特性可將其劃分為功能性需求(Functional Requirements)及非功能性需求(Non-functional Requirements)。功能性需求定義了系統的核心功能,而非功能性需求為系統層面的需求,且為核心模組所共用,例如logging、 authorization。雖然物件導向程式設計是目前最常被用來管理核心功能的方法論,但其對於橫跨(crosscutting)的非功能性需求則缺乏適當的模組化機制。剖面導向程式設計(Aspect-Oriented Programming)是一種新興的程式語言方法論,能夠利用新的模組化單位—aspect—有效處理橫跨性需求的模組化問題,因此本研究將剖面導向程式設計的觀念與技術運用在工作流程(Workflow)的領域中,並且以JBoss jBPM(Java Business Process Management)為基礎,設計jPDL(jBPM Process Definition Language)的剖面導向擴充語言AO4JPDL(Aspect-Oriented for jPDL),並擴充jBPM工作流程引擎(jBPM Workflow Engine),使流程設計人員能利用AO4JPDL解決橫跨性需求的模組化問題。 / Software-system is composed of functional requirements and non-functional requirements. Functional requirements define core functions of software-system. Non-functional requirements are crosscutting concerns such as logging, authorization and other elements common to many of the core modules. While object-oriented programming (OOP) is the most common methodology employed today to manage core functions, it is not enough to manage crosscutting concerns. Aspect-Oriented Programming (AOP) is a relative new methodology that specifically targeted the management of crosscutting concerns by introducing a new unit of modularization—an aspect—that realizes the concept of Separation of Concerns. Our research is to apply Aspect-Oriented Programming in the field of workflow. We implement Aspect-Oriented for jBPM Process Definition Language (AO4JPDL) and extend jBPM workflow Engine to support Aspect-Oriented Programming. AO4JPDL is a aspect-oriented extension to the jBPM Process Definition Language(jPDL). With AO4JPDL process designer can implement crosscutting concerns in aspects instead of fusing them in the core modules, resulting in a system that is easier to design, implement, and maintain.

以流程對映及Web服務為基礎,發展應用框架-以物流中心為例

何婉玲, Ho Wan-Ling Unknown Date (has links)
隨著軟體需求不斷增加及改變,組織現有系統架構無法做彈性調整,組織間系統亦無法溝通。物件導向的出現解決系統架構不易擴充及調整的問題,而發展一個良好的框架可達到軟體可再用性及物件導向優點。在框架發展的過程中,本研究將除了原有框架發展流程外,加入流程對映及Web服務的概念,最後輔以設計模式和框架recipe來發展一個完整的框架。為了切合實務上需求,本研究將以物流供應鏈和物流中心為例,根據框架發展流程,建立一個完整且健全的物流供應鏈框架。由於參與者間的訊息溝通無法用流程對映來表達,因此加入了Web服務的觀念,以適應分散式處理的需求。以此框架,各參與者可自行開發應用系統而不需改變整體的框架,在未來需求改變或增加的過程中,此框架也將解決系統不易調整的缺點。
