Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Identifying Weak Segmentation on the Fly to Improve Chinese Word Segmentation
No full text我們在本篇論文中提出了一個運用即時斷詞弱點辨識改善中文斷詞系統效能的方法，並可將此概念運用到任何學習演算法的模型中。主要是利用基礎模型產生的第一階段測試資料集，利用斷詞弱點辨識找出在斷詞中可能產生錯誤的區段，在將找到的錯誤候選區段利用網路強大的資源庫中找出有可能的錯誤更正詞，並將它加入更正詞辭典，在測試資料階段利用字典對特徵進行重新的標記，達到不用重新訓練模型就可以使用更正詞辭典的效果，進而去改善整體斷詞系統的效能。 我們將此概念運用於CRF模型中，並提出了三種錯誤候選區段的選擇方法和一套利用網路搜尋結果數和維基標題等尋找更新字詞的機制。在實驗中利用SIGHAN 2005 所提供的公開資料集，使用我們的方法下整體F-measure與基礎模型相比皆有所提升，而提升的效能與未知詞比率呈現強烈的正相關，且在未知詞的召回率方面對每個資料集都有明顯得成長，證明我們的系統對未知詞的擷取有很大的提升能力。而在面對SIGHAN 2014與NLPCC 2015等兩個資料內容為微博的資料集中，在基礎模型下加入我們效能都能有很顯著的提升，代表我們在處理社群網路等新興詞彙時有相當好的處理能力。We propose a new method to improve Chinese word segmentation system by identifying weak segmentation on the fly, and this idea can be implemented in any kind of statistical learning model. The method can be simply described in three steps. First, we use the segmentation result generated by our baseline model to identifying weak segmentations and denote them as error candidate tokens. Second, we use the powerful Internet resource to correct the error candidate tokens and collect the new words we found into a correction word dictionary. Third, we use this dictionary to relabel the testing data rather than retraining the model to improve the overall performance. We implement this idea by CRF and propose three ways to find the error candidate tokens, we also design a mechanism using the Internet searching counts and the title of wikipedia’s pages to find out new words which might be wrong segmented at the first place. In experiment in SIGHAN 2005 Chinese word segmentation Bakeoff, our work can make the baseline model has better performance in F-measure than before. In addition, it also has a significant improvement in OOV recall. In SIGHAN 2014 and NLPCC 2015 datasets, which are made of weibo data, the performance of the baseline model has a great promotion after applying our work on it. This shows that our work is powerful when dealing with the data of social media that contains lots of new words
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
