Materialized views (or Automatic Summary Tables—ASTs) are commonly used to improve the performance of aggregation queries by orders of magnitude. In contrast to regular tables, ASTs are synchronized by the database system. In this paper, we present techniques for maintaining cube ASTs. Our implementation is based on IBM DB2 UDB.

An ensemble representation refers to a statistical summary representation of a group of similar objects. Recent work has shown that we can form multiple ensemble representations – ensemble representations for a single feature dimension across multiple stimulus groups, ensemble representations for multiple feature dimensions in the same stimulus group, and ensemble representations across multiple sensory domains. In our study, we use hierarchical stimuli based on the Navon figures (Navon 1977) to study properties of ensemble representations across multiple spatial scales. In Experiments 1 and 3, we study properties of ensemble representations for the orientation and size feature dimension, respectively. In Experiment 2, we study properties of individual representations for the orientation feature dimension. Results indicate that it is possible to form ensemble representations across multiple spatial scales. Experiment 1 shows that the global ensemble representations may be extracted automatically (without intent) whereas the local ensemble representation is only extracted in response to task demands (with intent). Finally, in both Experiment 1 and Experiment 3, participants were more accurate at reporting the global ensemble representation than the local ensemble representation whereas in Experiment 2, performance did not differ across the levels. These results point towards global precedence in the formation of ensemble representations.

現今網路發達便利，人們資訊交換的方式更多元，取得資訊的方式，不再僅是透過新聞，透過論壇任何人都可以快速地、較沒有門檻地分享資訊。也因為這個特性造成資訊量暴增，就算透過搜尋引擎，使用者仍需要花費許多精力蒐集、過濾與處理特定的主題。本研究以巴哈姆特電玩資訊站─英雄聯盟哈拉討論板為例，期望可以為使用者提供一個全面且精要的遊戲角色描述，讓使用者至少對該角色有大概的認知。 本研究參考網路論壇探勘及新聞文件摘要系統，設計適用於論壇多篇文章的摘要系統。首先必須了解並分析論壇的特性，實驗如何從論壇挖掘出潛藏的資訊，並認識探勘論壇會遭遇的困難。根據前面的論壇分析再設計系統架構大致可分為三階段：1. 資料前處理：論壇文章與新聞文章不同，很難直接將名詞、動詞作為關鍵字，因此使用TF-IDF篩選出論壇文章中有代表性的詞彙，作為句子的向量空間維度。2. 分群：使用K-Means分群法分辨哪些句子是比較相似的，並將相似的句子分在同一群。 3. 句子挑選：根據句子的分群結果，依句子的關鍵字含量及TF-IDF選擇出最能代表文件集的句子。 我們發現實驗分析過程中可以看到一些有用的相關資訊，在論文的最後提出可能的改善方法，期望未來可以開發更好的論壇文章分類方式。 / With the establishment of network infrastructure, forum users can provide information fast and easily. However, users can have information retrieved through search engines, but they still have difficulty handling the articles. This is usually beyond the ability of human processing. In this study, we design a tool to automate retrieval of information from each topic in a Chinese game forum. We analyze the characteristics of the game forum, and refer to English news summary system. Our method is divided into three phases. The first phase attempts to discover the keywords in documents by TF-IDF instead of part of speech, and builds a vector space model. The second phase distinguishes the sentences by the vector space model built in the first phase. Also in the second phase, K-means clustering algorithm is exploited to gather sentences with the same sense into the same cluster. In the third phase, we choose two features to weight sentences and order sentences according to their weights. The two features are keywords of a sentence and TF-IDF. We conduct an experiment with data collected from the game forum, and find useful information through the experiment. We believe the developed techniques and the results of the analysis can be used to design a better system in the future.

隨著網路世界的興起，在面臨選擇難題時，民眾不僅會接收口耳相傳的資訊，也會以關鍵字上網搜尋目標資訊，但是在海量資料的浪潮中，如何快速的整合資料是一大挑戰。電影影評文章摘要可以幫助民眾進電影院前了解電影的資訊，透過這樣的方式確認電影是自身有興趣的電影。 本研究以電影：復仇者聯盟2影評66篇4616句、蝙蝠俠對超人：正義曙光60篇9345句、動物方城市60篇5545句、星際效應50篇4616句、高年級實習生62篇5622句為資料來源，以分群概念結合摘句之方法生成影評摘要。其中，利用K-Means演算法將五部電影的多篇影評特徵詞、句子進行分群後，使用TFIDF評比各分群語句的重要性來選取高權重語句，再以WWA方法挑選分群中不同面向的語句，最後以相似度計算最佳範本與各分群內容的相似度來決定每一群聚的排序順序，產生一篇具有相似內容段落和段落順序的影評多篇摘要。 研究結果顯示，原本五部電影影評對最佳範本之相似度為15.87%，經由本研究方法產生之摘要對最佳範本單篇摘要之相似度為21.19%。另外，因為影評中各分群的順序是比對最佳範本相似度而產生的排序，整篇摘要會具有與最佳範本相似段落排序的摘要內容，其中內容包含了電影影評中廣泛提到的相似內容，不同的相似段落讓文章摘要的呈現更具廣泛性。藉由此摘要方法，可以幫助民眾藉由自動化彙整、萃取的摘要快速了解相關電影資訊內容和協助決策。 / Abstract As Facing the Big Data issue, there are too many information on the website for reader to understand. How to perform and summarize essential information quickly is a challenge. People who want to go to a movie will also face this situation. Before choosing movies, they will search relative information of the movies. However, there are many film reviews all over the websites. Automatic text summarization can efficiently extract important information for readers, and conclude concepts of reviews on the websites. Through this method, readers can easily comprehend the best idea of all the reviews and save their time. The research presents a multi-concept and extractive film review summary for readers. It generates film review summary from the most popular blog platform, PIXNET, with extract-based method and clustering concept. The method using K-Means algorism let the film review summary focus on specific film to cluster the sentences by features, and having statistical sense and WWA method to measure the weight of sentences in order to choose the representative sentences. On the last step, it will compare to templates to decide the sequence of classified sentences and summary all represent sentences from each cluster. The research provides a multi-concept and extractive film review summary for people. From the result, there are five movies, which are used summary method increase the average similarity to 21.19% that comparing between the film reviews summary and templates summary. It shows that the automatic film reviews summarization can extract the important sentences from the reviews. Also, with comparing template method to order the cluster, it can sequentially list the cluster of the sentences to generate a movie review, which saves readers’ time and easily comprehend.

Background: Antimicrobial-resistant infections result in hospital stays costing between $18,000 and $29,000. As of 2009, Centers for Medicare and Medicaid Services no longer upgrade payments for hospital-acquired infections. Hospital epidemiologists monitor and document rates of individual resistant microbes in antibiogram reports. Overall summary measures capturing resistance within a hospital may be useful. Objectives: We applied four techniques (L1- and L2-principal component analysis (PCA), desirability functions, and simple summary) to create summary measures of resistance and described the four summary measures with respect to reliability, proportion of variance explained, and clinical utility. Methods: We requested antibiograms from hospitals participating in the University HealthSystem Consortium for the years 2002–2008 (n=40). A clinical team selected organism-drug resistant pairs (as resistant isolates per 1,000 patient days) based on 1) virulence, 2) complicated or toxic therapies, 3) transmissibility, and 4) high incidence with increasing levels of resistance. Four methods were used to create summary scores: 1) L1- and L2-PCA: derived multipliers so that the variance explained is maximized; 2) desirability function: transformed resistance data to be between 0 and 1; 3) simple sum: each resistance rate was added and divided by the square root of the total number of microbes summed. Simple correlation analyses between time and each summary score evaluated reliability. For each year, we calculated the proportion of explained variance by dividing each summary score’s variance by the variance in the original data. Clinical utility was checked by comparing the trends for all of the individual microbe’s resistance rates to the trends seen in the summary scores for each hospital. Results: Proportion of variance explained by L1- and L2-PCA and the simple sum was 0.61, 0.62, and 0.29 respectively. Simple sum and L1- and L2-PCA summary scores best followed the trends seen in the individual antimicrobial resistance rates; trends in desirability function scores deviated from those seen in individual trends of antimicrobial resistance. L1- and L2-PCA summary scores were more influenced by MRSA rates, and the simple sum score was less influenced. Pearson correlation coefficients revealed good reliability through time. Conclusion: Deriving summary measures of antimicrobial resistance can be reliable over time and explain a high proportion of variance. Infection control practitioners and hospital epidemiologists may find the inclusion of a summary score of antimicrobial resistance beneficial in describing the trends of overall resistance in their yearly antibiogram reports.

When judging special appeals the Superior Labor Court (TST) does not meet the double degree of jurisdiction. These special appeals aim at the harmonization of national jurisprudence. These are extraordinary legal remedies, without review of the evidence ? already produced and valued by the ordinary courts. The labor special appeal system, inaugurated with Law 13.015 of 2014, is investigated in this research. The hypothesis of recognition of binding precedents, at least in the form of mandatory judicial paradigms, is combined with the examination of the subsidiary and supplementary application of the Civil Procedure Code of 2015 to the labor procedure. Uniformising case law is no longer just mandatory. Now, it is a legal imposition that has its own means of execution. In the labor field, the objective is to restrict the admission of special appeals to the TST. Especially when it is demonstrated that there are current and conflicting decisions on the same legal issue in the same Regional Labor Court (TRT). This systematics confirms the relevance of the Superior Labor Court as a guideline of the Labor Court in general. Prevailing theses and precedents of the Regional Labor Courts are also valued by the new systematics. Especially, because they become the first parameter to point jurisprudential divergence apt to the claim of special appeals. In this context of a wide normative renewal, the theoretical conformation of the binding precedents gains practical importance for the fulfillment of the duties set by the procedural legislation: unity, stability, integrity and coherence. This thesis proposes to articulate those duties as a means of linking to the judicial precedent as a legal norm to be observed and followed in Brazil. Current problems such as mass demands, repetitive cases, and the unpredictability of judicial decisions in front of normative vagueness that provoke inevitable interpretative divergences in the application of Law are highlighted in this research. The hypotheses tested aim to strengthen the Judiciary as an institution aimed at securing and developing the democratic model, holding credibility due to the social effectiveness of its decisions in line with the current legal system. The efficiency of judicial provision requires a distinction in the treatment of specific causes and respect for the complexity of the questions put to judicial review, always in accordance with the Constitution. Decisions that are responsible, impartial, fully grounded, debated in a contradictory manner, and aimed at the effective realization of Labor Law in a society that has among its foundations the social value of work together with free initiative. To improve practice, one must formulate and test new theories. This is the main line of the study. / La vinculaci?n del Derecho con la garant?a de la libertad es el tema central de esta tesis. A juzgar recursos de revista, y embargos de la SDI, el Tribunal Superior del Trabajo no cumple con los dos niveles de jurisdicci?n. Estos recursos est?n dirigidos a la normalizaci?n de la jurisprudencia nacional. Son caracter?sticas de jur?dico extraordinario sin revisi?n de la evidencia ? producida y valorada por los tribunales ordinarios. La sistem?tica de apelaci?n que se abri? con la Ley 13.015 del a?o 2014 se estudia en esta investigaci?n. La hip?tesis del reconocimiento de precedente vinculante, al menos en la forma de paradigmas judiciales de obligado cumplimiento, se combina con el examen de la aplicaci?n filial y supletoria del C?digo de Procedimiento Civil de 2015 para el proceso del trabajo. Estandarizar las decisiones ya no es s?lo necesariamente posible. Ahora bien, es un requisito legal que ha poseer medios de ejecuci?n. El objetivo es restringir la admisi?n de los recursos de revista. Especialmente cuando se demuestra que hay decisiones actuales y contradictorias sobre la misma cuesti?n jur?dica del mismo Tribunal Regional del Trabajo. Este sistema confirma la relevancia de la Corte Superior de Trabajo como gu?a de los Tribunales y Jueces de Trabajo. Tambi?n valora las teor?as y visiones generales del Tribunal Regional del Trabajo. Sobre todo porque convertirse en el primer par?metro a punto de mostrar divergencia jurisprudencial capaz de recurso de revista. En este amplio contexto de renovaci?n de las normas, la conformaci?n te?rica de los precedentes gana importancia pr?ctica para el cuidado de los deberes se?alados por la ley de procedimiento: la unidad, la estabilidad, la integridad y la coherencia. Se propone la articulaci?n de estos deberes como un medio de vincular el precedente judicial como una norma jur?dica que se deber? observar y seguir en Brasil. Cabe destacar problemas actuales como casos repetitivos, masivos y la imprevisibilidad de las resoluciones judiciales en raz?n de vaguezas normativas que causan diferencias interpretativas inevitables en la aplicaci?n de la ley. Las hip?tesis probadas est?n destinadas a reforzar el Poder Judicial como instituci?n dirigida a garantizar y desarrollar el modelo democr?tico, con la celebraci?n de credibilidad debido a la eficacia social de sus decisiones de acuerdo con el sistema legal existente. La eficiencia de los servicios judiciales requiere distinci?n en el tratamiento de las causas espec?ficas y el respeto por la complejidad de las preguntas formuladas a revisi?n judicial, siempre de acuerdo con la Constituci?n. Decisiones responsables, imparciales, totalmente fundamentadas, discutidas en contradictorio, y dirigidas a la realizaci?n efectiva de la legislaci?n laboral en una sociedad que tiene entre sus fundamentos el valor social del trabajo junto con la libertad de empresa. Para mejorar la pr?ctica deben se formular y probar nuevas teor?as. Esta es la l?nea de este est?dio. / Vincular o Direito com a garantia da liberdade da pessoa humana ? a quest?o central da tese.

Among the institutes, the summary bindings introduced by EC 45/2004 make possible to do analysis of the entire political, social and Brazilian legal system, since they arise from abnormalities that may jeopardize state security. The idea is to promote, through philosophical discussion and the historical reconstruction of social and political ideals, how summary bindings affect the current landspace of the Federative Republic of Brazil. It is not just about addressing the issue related to judicial activism resulting from summary bindings, but also and mainly explores the institute, confronts concepts and puts down theories, grounded in the study of philosophical models treated along the dissertation. Therefore, we intend to address not only the positions against the summary bindings, as well as to refute the favorable understandings, which exist by evidence and are found in the majority doctrine of constitutional law Brazilian. We work in order to focus not only on legal institutions, but we try to find at the heart of the society itself, manners and the discussion about the scope of power and its way of working in the state. Conceiving the story, along with the philosophical study were outstanding to achieve the results listed here, from the theoretical foundation to the critical development of the institutes, existing institutions and concepts in Brazil and it is precisely the tripartite model of separation of executive functions, legislative and judiciary that the major part of this work is framed, especially when we analyze the judicial activism of the Supreme Court and the prerogative created with summary bindings, since it is the last resort of the Brazilian system, reason why the analysis about the State General Theory stands as crucial to the final understanding of the work / O ordenamento jurídico brasileiro permite muitas interpretações do seu modelo, de suas instituições e de seu alcance na sociedade. Dentre os institutos, as Súmulas Vinculantes inseridas pela EC 45/2004, possibilitam a análise de todo o sistema político, social e jurídico brasileiro, vez que resultantes de anormalidades que podem abalar a segurança do Estado. A ideia é fomentar, através da discussão filosófica e da reconstrução histórica dos ideários sociais e políticos, como as súmulas vinculantes afetam a conjuntura atual da República Federativa do Brasil. Não se trata apenas de abordar o tema referente ao ativismo judicial decorrente das súmulas vinculantes, mas também e principalmente dissecar o instituto, enfrentar conceitos e derrubar teorias, embasados justamente no estudo dos modelos filosóficos tratados ao longo da dissertação. Para tanto, procuramos abordar não apenas os posicionamentos contrários às súmulas vinculantes, como de igual feita refutar os entendimentos favoráveis, que por evidência existem e se encontram na doutrina majoritária sobre o Direito Constitucional Brasileiro. Trabalhamos de forma a não nos concentrar somente nos institutos jurídicos, mas procuramos encontrar no âmago da própria sociedade as formas e a discussão sobre o alcance do poder e do seu funcionamento do Estado. Conceber a história, juntamente com o estudo filosófico, foram preponderantes para alcançar os resultados aqui elencados, desde a fundamentação teórica até o desenvolvimento crítico sobre os institutos, instituições e conceitos existentes no Brasil e é justamente no modelo tripartite de separação de funções em Executivo, Legislativo e Judiciário que a maior parte do trabalho se enquadra, sobretudo quando analisamos o ativismo judicial do Supremo Tribunal Federal e a prerrogativa criada com as súmulas vinculantes, já que é ele a última ratio do sistema brasileiro, motivo pelo qual a análise em torno da Teoria Geral do Estado se coloca como fundamental para o entendimento final do trabalho
