新聞事件於社群媒體之發展歷程的視覺化分析工具―以Twitter為例 / A visual analysis tool on the news development in social media : using twitter as an example

林聖翔, Lin, Sheng Hsiang Unknown Date (has links)
當一個新聞事件發生時,相關訊息通常會被新聞媒體所報導,而民眾亦能透過網路上各種管道發表己見。近年來,社群媒體已成為記者與民眾散播訊息的重要平台,也是研究新聞發展的重要管道。但隨著時間累積的龐大訊息量,使用人工的方式來收集資料,以了解事件整體脈絡的方式往往事倍功半。本研究利用Twitter做為資料來源,透過各種視覺化的圖表及統計資訊,協助新聞研究者透過漸進的方式操作系統各階段的功能,逐步篩選出新聞事件的關鍵推文。系統可客製化參數的設計讓使用者能依觀察到的現象來調整系統推薦的推文,進而達到瞭解發展歷程的目標。我們邀請4位受試者,透過系統操作教學及引導式任務讓受試者學習如何使用系統,最後讓受試者自由探索,並透過問卷與訪談的方式來探討系統的優缺點。問卷的評分使用5分量表,實驗結果在有用性向度的平均分數為4.1,表示本系統能有效地幫助使用者分析事件的發展歷程;而易用性向度的平均分數為4.3,顯示受試者對本系統的易用性表示認同。本系統的主要目的,是希望能協助使用者找尋新聞事件中的關鍵推文,並瞭解其發展歷程,由實驗結果與受試者回饋顯示,本研究的視覺化分析系統具有幫助理解事件脈絡的能力,證實了本系統的發展價值。 / When a new event happens, related messages can not only be released by the press but also through various network channels by the general public. In recent years, social media have become a popular and important platform for news reporters and the general public to propagate news messages. However, due to the massive amount of messages on the social media platforms, it is very time consuming to manually collect these data in order to grasp the development of a news event over time. In this research, we aim to develop a visualization system that can help researchers find key tweets on twitters for a news event in an incremental manner. Our system allows a user to customize design parameters for finding key tweets from various aspects in order to understand how a news event evolve over time on social media. We have invited four participants to test use our system through a tutorial, guided tasks, and free exploration. A questionnaire survey and interview were conducted after the experiments. The evaluation results show that the average score for the usability dimension is 4.1 out of 5, showing that the system can effectively assist the users in analyzing the development of a news event. The average score for the ease-of-use dimension is 4.3, meaning that most users agree that our system is easy to use. The results reveal that our research goals of helping users find key tweets and understand news development have been achieved and the development of such a visualization system is valuable for news analysis on social media.

團隊發展歷程對新創事業營運影響之研究—以個案公司為例 / The impact of team developmental process on the entrepreneurial performance - Case study companies as example

呂文正, Lu, Wen Cheng Unknown Date (has links)
在創業的過程中,資源與整體能力的累積是依循漸進的。從一開始的小團隊、小規模經營,到後來以組織戰擴張營業額與營運績效,可謂是成功創業案例中,相當重要的歷程。如何能創業成功,創業的演變歷程扮演了相當關鍵的角色。有道是「萬丈高樓平地起」,一個企業要能克服瓶頸,才能成長茁壯。 如何能夠讓創業的過程中更有效管理,就是本研究欲探討的重點。本研究利用Tuckman在1977年所發表的團隊發展歷程理論,整合了個案研究,並透過創業家的訪談,進行團隊與創業管理的探討。透過團隊發展歷程理論中,對於形成階段、風暴階段、規範階段、表現階段、終止階段等團隊發展歷程五大階段的分析,了解到銷貨與通路管理、人力資源管理、財務管理、研發管理、生產管理等等議題,並且結合文獻回顧與專家訪談的方式,作出結論與建議。 在個案選擇的部分,本研究是以電子相關的創業作為個案,其中的C公司是經營DRAM與FLASH的銷貨作為營運主力,H公司則是以電源管理相關的電子零組件、模組作為利基點。整體來說,本研究以電子相關的創業團隊探討為主,希望能對產業界與學術界有所助益。 / In the course of establishing a business, resources and overall capacity usually accumulate step by step. It begins with a small team, small-scale operation and gradually expands its turnover and performance, which can be described as an indispensible process among any successful cases, and the entrepreneurial developmental process also plays a critical role. As a saying goes, "Every skyscraper starts from scratch", a company must be able to overcome its bottlenecks in order to grow. How to make management more efficient during the developmental process is the focus of this study. This study utilizes the theory of Team Developmental Process published by Tuckman in 1977, integrating case studies and interviews with entrepreneurs to discuss team and entrepreneurial management. Analyzing the theory of team development process, which includes forming stage, storming stage, norming stage, performing stage, and adjourning stage, I gained an insight into several issues such as the sales and channel management, human resources management, financial management, R & D management, production management. Combining literature review and interviews with experts, I reach my conclusions with some suggestions at the end. In terms of case selection, this study uses electronics-related firms as case study, among which, the sales of C Company specializes on DRAM and FLASH, whereas H Company on power management, electronic components and modules as its niche point. Overall, this study focuses on electronics-related entrepreneurial team, hoping to be helpful to the industry as well as the academia.

資訊組織設計之研究-以我國政府部門資訊組織為例 / The Design of Information Departments—An Empirical Study of Information Departments in Taiwan Government

李幸秋 Unknown Date (has links)
我國政府積極投入電子化政府建設已有十多年,與過去研究(Weill & Ross, 2004)中論及非營利組織相當重視資訊科技投資的研究結果是一致的,並且,資訊科技的導入與落實需要組織中其他因素的配合以達到良好的成效,其中一個重要的因素即為組織結構的調整。過去關於資訊組織結構的研究,大多以一般的企業為研究對象。 隨著2000年之後,我國政府開始從事組織改造,政府組織策略及資訊組織改造對我國經濟的影響日益顯著。並且,隨著資訊組織在政府整體發展中的角色日益重要,對政府資訊組織發展的研究成為最新的趨勢和最有潛力的議題之一。 為了前瞻未來政府資訊組織的發展,本論文對於我國某部級政府資訊組織的發展歷程以及其與所屬機關資訊組織之間的關係進行個案實證研究,並且,對於未來個案的組織結構、功能任務、以及與所屬機關資訊組織之間關係,與相關主管進行訪談討論,並進行歸納分析。本研究的結果為:資訊科技演進與調整資訊組織的結構、調整資訊組織的地位、調整資訊組織的授權型態有所關聯、以及在專業式官僚組織的型態下可透過資訊治理的落實來接受創新的挑戰。 本論文亦總結學術與實務意涵。學術價值歸納後呈現在以下幾個方面:對有關組織結構理論進行系統性的回顧和總結、政府資訊組織結構演進模型的建立、以及對政府資訊組織發展歷程進行客觀的描述。而實務意涵主要展現在以下幾個方面:有助於分析政府資訊組織演進發展的歷程和趨勢、以及有助於我國政府資訊組織從組織面迎接電子化政府挑戰。
