文字探勘在總體經濟上之應用- 以美國聯準會會議紀錄為例 / The application of text mining on macroeconomics : a case study of FOMC minutes

黃于珊, Huang, Yu Shan Unknown Date (has links)
本研究以1993年到2017年3月間的193篇FOMC Minutes作為研究素材,先採監督式學習方法,利用潛在語意分析(latent semantic analysis,LSA)萃取出升息、降息及不變樣本的潛在語意,再以線性判別分析(Linear Discriminant Analysis, LDA)進行分類;此外,本研究亦透過非監督式學習方法中的探索性資料分析(Exploratory Data Analysis, EDA),試圖從FOMC Minutes中找尋相關變數。研究結果發現,LSA可大致區分出升息、降息及不變樣本的特徵,而EDA能找出不同時期或不同類別下的重要單詞,呈現文本的結構變化,亦能進行文本分群。 / In this study, 193 FOMC Minutes from 1993 to March 2017 were used as research materials. The latent semantic analysis (LSA) in supervised learning methods was used to extract the potential semantics of interest rate increased, decreased, and unchanged samples, and then linear discriminant analysis (LDA) was used for classification. In addition, this study attempts to find relevant variables from FOMC Minutes through exploratory data analysis (EDA) in unsupervised learning methods. The results show that LSA can distinguish the characteristics of interest rate increased, decreased, and unchanged samples. EDA can find relevant words in different periods or different categories, show changes in the text structure, and can also classify the texts.

大陸員工價值觀與台商管理行為的互動──地區次文化差異研究 / The Conflict & Adaptation between Mainland Chinese Value System and Taiwan Enterprises' Management Style: a Region-based Sub- cultural Research

何國全, Ho, Kuo Chuan Unknown Date (has links)
台灣企業自民國七十年以來開展對外投資的步伐,而大陸地區又是許多外 移台灣廠商的最愛。雖然兩岸本根植於同一文化而發展,但是四十餘年的 分隔已使得一般大陸員工在價值觀念上與我們有異。直到目前我國企管學 界尚未有系統地進行兩岸跨文化管理之比較研究,眾多台商的成敗經驗因 此無法有效累積,故本研究的目的在於:一、了解大陸員工的價值想法; 二、探訪台商針對兩岸文化差異而採用的特殊管理作為;三、依研究結果 為台商提出配合兩岸文化差異而改進管理效能的建議。研究結論認為:由 於大陸員工與台灣幹部同仁間的價值觀念不同,登陸的台灣企業主所採取 的管理作法並不能完全因襲過去在台灣的模式;但是一旦對登陸懷有經濟 因素以外的特殊投資動機或策略目的,台商的管理行為就會有特別的考量 。大陸員工對於上級「職務權威」的接受程度比台灣員工低,所以台資企 業管理幹部需要具備更多的「魅力權威」才能提升管理績效;多數大陸人 習慣集體行動,比較不願意冒個人風險,並且在人際行為上具有更強的防 衛性和攻擊性。最後,隨著時間的發展,大陸員工的價值觀念和工作態度 會受到外商企業管理制度與本身從業經驗的影響而產生變化。台商企業惟 有保持高度的彈性與對環境變化的警覺,才能針對現實情況、適切地調整 管理方法,從而得到最佳績效。

優勢觀點為基礎之探索教育團體對感化教育少年增強權能的成效 / The effects of strength-based project adventure education group on empowerment for juvenile inmates

蔡杰伶 Unknown Date (has links)
本研究旨在探討「優勢觀點為基礎之探索教育團體」對感化教育少年「增強權能」的成效,並根據研究結果提出「優勢觀點為基礎之探索教育團體」作為犯罪問題行為少年處遇策略之適用性。   本研究採「不等質控制組」準實驗設計,以「誠正中學」中受感化教育的少年為對象。其中,實驗組成員23名,實驗期間接受九次的「優勢觀點為基礎之探索教育團體」;四組對照組成員共81名,接受一般輔導課程。 本研究使用量化工具-「增強權能量表」,分別進行前測、後測與追蹤測,並以「無母數檢定(Mann-Whitney U統計量檢定、Wilcoxon符號等級檢定)」作為統計方法,檢驗分析實驗處遇的立即效果與延續效果。本研究同時使用質化工具-「反思札記」,藉由個別成員活動反思紀錄的整理與分析結果,提出成員在團體中的「學習收穫」與「增強權能」的展現,以作為實驗效果之補充。 本研究的主要發現如下: 一、「優勢觀點為基礎之探索教育團體」對感化教育少年「增強權能」有正向顯著影響,且效果能延續加乘。 二、一般矯正教育措施對「增強權能」也可以帶來正向影響,但效果卻未能持續。 三、成員的「增強權能」會隨著「團體歷程」呈現「階段性」發展。 四、「優勢觀點為基礎之探索教育團體」適用於受感化教育少年,也可為少年犯罪問題行為矯治之有效策略。 根據研究發現,提出下列幾點建議: 一、對於青少年犯罪矯治實務 (一)建議可將「優勢觀點為基礎的探索教育團體」安排於新生入校階段實施。 (二)建議可將「增強權能」程度作為矯正學校成效評估指標之一。 (三)建議矯正學校內可以增設「低空繩索設施」。 (四)建議校內舉辦探索教育訓練,讓工作人員都具備探索活動帶領能力。 二、對於未來從事相關研究者 (一)先深入瞭解「矯正學校機關特性」以利預先克服執行面之可能干擾 (二)須格外注意保密相關的「研究倫理」 (三)團體人數掌握在8-12人,或是安排協同領導者 參、對於未來計畫運用「優勢觀點為基礎之探索教育團體」的實務工作者 (一)領導者在團體過程中與成員互動要積極落實「優勢觀點」實務要素。 (二)在方案執行中持續進行「過程評估」。 (三)在團體方案結束後「持續輔導」。 / This research is to investigate “The Effects of Strength-based Project Adventure Education Group” on “Empowerment” for juvenile inmates and according to the research results to bring up the application of “Strength-based Project Adventure Education Group” on treatment strategy of juvenile delinquents. The nonequivalent control group quasi-experimental design was utilized in this study. And the subjects of this research were Juvenile Inmates in Chengjheng High School. There were 23 members in experiment group and during experiment period, they accepted 9 times of “Strength-based Project Adventure Education Group”; at the same time, there were 4 control groups (total 81 members) who accepted usual student counseling courses to compare. The study employed “Empowerment Scale” to conduct pretest, posttest, and long-term measures. Then the data were analyzed by nonparametric (Mann-Whitney U Test and Wilcoxon Sign Rank Test) as statistics method to examine and analyze instant and long-term effects on experiment treatment. And the researcher also used qualitative tool “introspection notes” to collect and analyze the consequences from self-observation records on individual member’s activities and addressed the performances of members on “Learning Gains” and “Empowerment” in groups as supplementary of experiment effects. And the main findings of this research are as below: 1. “Strength-based Project Adventure Education Group” has positive and obvious influences on “Empowerment” of juvenile delinquents and the effects can be synergistic continuously. 2. Usual student counseling courses can create positive influences on “Empowerment” as well but the effects cannot be continuous. 3. The “Empowerment” of members can develop “Stage by Stage” along with “the Progress of Groups”. 4. “Strength-based Project Adventure Education Group” is suitable for juvenile delinquents and efficient strategy to correct their criminal problems and activities. Based on the findings of this research, the researcher has suggestions below. 1. For the practices on correction of juvenile delinquents: a. “Strength-based Project Adventure Education Group” can be implemented when new students just enter schools. b. The degree of “Empowerment” can be as one of criteria on outcomes evaluation of correction schools. c. Correction schools can add “the Facilities of Low Ropes Course”. d. Correction schools can hold Project Adventure education training to let all workers have leading abilities of adventure activities. 2. For future researchers who focus on related topics: a. Understand “Characteristics of Correction Schools and Institutions” deeply first in order to avoid any possible interference on the aspect of application in advance. b. Should pay particular attention to privacy-related "Research Ethics". c. Group members should be controlled 8-12 people or arrange collaborative leaders. 3. For practitioners who plan to adopt “Strength-based Project Adventure Education Group” in the future: 1. Leaders must implement practical essentials of “Strengths Perspective” in the progress of groups and between the interactions with members. 2. Keep proceeding with “Evaluation of Progress” when the project is carried out. 3. Maintain student counseling after the project is finished.

探索性資料分析方法在文本資料中的應用─以「新青年」雜誌為例 / A Study of Exploratory Data Analysis on Text Data ── A Case study based on New Youth Magazine

潘艷艷, Pan, Yan Yan Unknown Date (has links)
隨著經濟繁榮和網絡發展的日新月異,線上線下每時每刻都產生龐大數據,其中約有80%的文字、影像等非結構化數據,如何量化和採取適合的分析方法,成為有效提取有價值信息及對其加以利用的關鍵。針對文字類型的資料,本文提出探索性資料分析方法,並以《新青年》雜誌的語言變化為例,呈現如何選取文本特徵并对其量化及分析的過程。 首先,本文以卷為分析單位,多角度量化《新青年》雜誌各卷的文本結構,包括文本用字、用句、文言和白虛字使用以及常用字詞共用等方面,通過多種圖表相結合的呈現方式,窺探《新青年》雜誌語言變化歷程以及轉變特點。這其中既包括了對文言文到白話文轉變機制的探索,也包括白話語言演化的探索。其次,根據各卷初探的結果,尋找可區隔文言文和白話文兩種語言形式的文本特徵變數,再以《新青年》第一卷和第七卷為訓練樣本,結合主成分和羅吉斯迴歸,對文、白兩種語言形式的文章進行分類訓練,再利用第四卷進行測試。結果證實,所提取的文本變數能夠有效實現對文、白兩種語言形式的文章的區分。此外,本文亦根據前述初探結果以及人文學者經驗,探索《新青年》雜誌後期語言形式的變化,即從五四運動時期的白話文至以「紅色中文」為特徵的白話文(二戰之後中國使用的白話文)的變化。以第七卷和第十一卷為樣本進行訓練,結果證實這兩卷語言形式存在明顯區別;並加入台灣《聯合報》和中國大陸的《人民日報》進行分類預測,發現兩類報刊的語言偏向有明顯差異,值得後續深入研究。 / Tremendous data are produced every day, due to the rapid development of computer technology and economics. Unstructured data, such as text, pictures, videos, etc., account for nearly 80 percent of all data created. Choosing appropriate methods for quantifying and analyzing this kind of data would determine whether or not we can extract useful information. For that, we propose a standard operating process of exploratory data analysis (EDA) and use a case study of language changes in New Youth Magazine as a demonstration. First, we quantify the texts of New Youth magazine from different perspectives, including the uses of words, sentences, function words, and share of common vocabulary. We aim to detect the evolution of modern language itself as well as changes from traditional Chinese to modern Chinese. Then, according to the results of exploratory data analysis, we treat the first and seventh volumes of New Youth magazine for training data to develop classification model and apply the model to fourth volume (i.e., testing data). The results show that the traditional Chinese and modern Chinese can be successfully classified. Next, we intend to verify the changes from modern Chinese of the May 4th Movement to those by advocating Socialism. We treat the seventh volume and eleventh volume of New Youth magazine as training data and again develop a classification model. Then we apply this model to the United Daily News from Taiwan and People’s Daily from Mainland China. We found these two newspapers are very different and the style of United Daily News is closer to that of seventh volume, while the style of People’s Daily is more like that of eleventh volume. This indicates that the People’s Daily is likely to be influenced by the Soviet Union.

新住民子女就學的空間社會學分析 / 無

謝芳吟 Unknown Date (has links)
1980年代末以降,臺灣跨國婚姻數量大幅增加,新住民子女就學人口成長速度亦十分驚人,根據教育部統計,94-104學年度間,就讀國中小的新住民子女自60,258人增至207,733人,成為不可忽視的群體。如何全面而精確瞭解該群體的空間分布與特徵,乃是了解新住民子代教育相關議題的重要基礎,過往研究卻未對此有所掌握。本文使用內政部統計處社會經濟資料平臺所發布之103-105年全國行政區國民小學、國民中學統計,運用R語言與Quantum GIS地理資訊系統,進行空間統計分析與視覺化地圖繪製,更藉由階層式集群分析法將臺灣本島區分出不同的教育環境背景類型,並以疊圖將兩者相互對照分析,企圖回答新住民子代就學人口所在之處,以及該群體所處地區的學校教育特性之基本命題。 研究結果顯示,無論國小或國中教育階段,新住民子女學生絕對人口及族群人口比率的空間分布,皆具有地方歧異性,顯著呈現出不均質的樣態,主要的空間聚集區有北北桃地區(含新竹縣北部)、竹苗地區與雲嘉南地區。本文亦發現,人口聚集的鄉鎮市區內,學校教育環境背景差異甚巨。北北桃地區的國小教育環境背景類型屬於「都會型」或「都會人口密集型」,國中階段分屬「都會偏遠混合型」或「都會人口密集型」;竹苗地區與雲嘉南地區的國小教育環境背景類型,除了臺南市楠西區為「都會型」外,其餘一概為「偏遠型」鄉鎮;國中階段甚至呈現「都會偏遠混合型」、「高生師比混合型」、「顯著少數型」三種面貌。 最後,本文指出,新住民子女就學人口分布,超越人為的行政界線劃分,形成跨多重縣市疆界的顯著聚集熱區,不僅如此,該群體落腳區域的教育環境背景類型存在差異。未來,政府單位若要制訂或實施相關政策,應考量新住民就學人口的空間分布,以及分布地的教育環境背景特性據,以達到更好的資源配置與政策安排。

運用文字探勘技術分析金融科技之發展與趨勢 / Applying text mining techniques to the development and trends of fintech's patent

郝紹君, Hao, Shao Chun Unknown Date (has links)
現今科技日新月異,不斷突破創新,產業環境變動的步調也越來越快,新竄出之金融科技(Finance Technology)的應用,使得許多企業越加注重技術方面的研發創新,尤其,善加運用專利資訊能有效節省研發經費與時間。因此如何有效運用專利是企業維持競爭優勢不可或缺的一環。 有鑑於此,本研究搜集近年各國專利資料庫之專利資料,將資料分為三個時期,並區分申請中與已申請之專利資料,透過文字探勘技術與機會探索分析出金融科技之發展與趨勢,了解各時期詞彙間之關聯性與差異,再搭配視覺化工具KeyGraph,以描繪出金融科技領域之相關詞彙關聯趨勢圖,挖掘未來潛在趨勢。 本研究之結果了解金融科技在各時期的趨勢發展變化與尋求脈絡,以及過去各時期之專利佈局,因而從結果中發現金融科技之發展方向主體為支付領域,許多支付科技接連出現在三個時期中。然而近幾年,其他金融領域如投資、融資、保險、資料分析等也漸漸浮出,從本研究之第三個時期的高頻字詞高達34個可看出,可見金融科技之專利發展佈局已快速從支付領域拓展至其他金融領域。本研究所挖掘出之潛在趨勢顯示了未來金融科技領域中將會有五大重點發展領域,分別為服務整合領域之雲端科技、支付領域之生物辨識與穿戴支付與加密貨幣、資料分析領域之機器學習與人工智慧、信息收集與處理領域之遠程信息處理科技、以及理財投資領域之理財機器人。 期望本研究結果能幫助企業,在面臨新科技不斷衝擊產業,而產業不斷尋求創新發展之下,能夠快速檢閱目前市場趨勢,藉此釐清並改善自身之發展策略,以因應外部環境之變動,提供企業作為金融科技發展之策略參考,也能有助於企業釐清與制定金融科技之投資方向,以擁有持續的競爭優勢。 / Nowadays, with the rapid advancement of information technologies, the changes of business environment and the way to deal with the changes are becoming faster and faster. The development and adoption of new financial technologies has made many enterprises pay more attention to the research and development (R&D) initiatives. Besides, making good use of patent information can effectively save the budget and time of R&D, so how to effectively use patent information is an indispensable part for enterprises to maintain their competitive advantages. This study collected the patent data from the national patent database, and divided the data into three periods, and distinguished the data between the applying and the applied patents. Through the text mining techniques and chance discovery, this study explored the development and trends of financial technology and also aimed to understand the relevance and differences between the major terms in each period. Then, with the visual tool, KeyGraph, this study illustrated the associations between related terms, and proposed the potential future trends based on the graphs. The results of this study help monitor the changes of the trends and financial technology’s development in the three periods, and understand the patent portfolios in each period. This study has found that the main direction of financial technology’s development is the payment field. Many technologies related to payment have successively appeared in the three periods. However, in recent years, other financial areas such as investment, financing, insurance, data analysis and other areas are gradually emerging, since we found 34 high-frequency terms in the third period. This also shows that the development of financial technology’s patent portfolios has expanded from payment to other financial areas. The potential trends of financial technology’s development in this study are five areas, namely, technologies of cloud, biometric and wearable payment and cryptocurrency, machine learning and artificial intelligence, telematics technology, and robo-advisors. It is expected that this study can serve as a reference for the development of financial technology, and help enterprises be able to quickly review their current market trends, clarify and improve their own R&D strategies to respond to the changes in the external environment. Also, it is hoped that the results can help enterprises clarify and develop their own investment directions to maintain competitive advantages.
