Methodic of applying Topic Maps technology to modernization of a content management system.
No full textThe usage of a classic content management system (CMS) has spread in the market of informational technologies because information is edited, authorized and published much easier in a multi-user environment. CMS is an ideal choice for large-scale organizations willing to control big amount of data from various resources. Usually this kind of information is presented in a web portal. However some weak points are found in a CMS as well. Particularly in organization of information, metadata support areas. Associations between various CMS objects such as blogs, wiki pages, information display elements aren’t supported enough. Similar to a file system many typical CMS store specific content objects in hierarchical catalogs. It is quite difficult to use this tree structure as information doesn’t fit there. Furthermore one association “type-instance” type does not define the purpose of information in the catalogs clearly. So this article describes how Topic Maps technology helps to avoid the limitations in organization of information used in a content management system. All the strengths of a classic CMS remain. Technology is built on top of CMS and lets the user describe the desired content in a topic map. Methodic explains Ontopia and Liferay integration, necessary configuration, ontology making and displaying Topic Maps information with portlets. Nowadays this open source approach is claimed to be one of the easiest and cheapest in building Topic Maps based web portals
Hybrid classification model for neural impairment detection.
No full textDissertation addresses problematics related to the analysis and diagnosis of central nervous system disorders (CNSD) using mobile smart devices and Self-Administered Gerocognitive Exam (SAGE) testing methodology. Based on a priori scientific knowledge, an extension of SAGE methodology for detecting tremor, cognitive, speech and energy expenditure impairments for CNSD patients is proposed in this work. The practical significance of this dissertation has been evaluated by the implementation of Neural Impairment Test Suite (NITS) Android mobile application, which provides feedback on the patient's health status and makes predictions on disease progression. Early stage Huntington’s, Parkinson’s, dementia, cerebral palsy CNSD patients and healthy test subjects not at risk group were involved in experimental research. Supervised learning classifiers were integrated in this dissertation and hybrid model was developed for combining single classifiers into an ensemble. Experiments were carried out for solving sick vs. healthy binary classification problem. Implemented classifier ensemble (hybrid model) results in ~2% increased accuracy, as compared to standalone models, i.e. 96.12% as best-fit combination based on the highest accuracy value and minimum time expenditure (0.59 seconds) for model training
HTML document content comparison algorithm /
No full textThis paper describes still encountered problems of documents visual content comparison in contemporary computerized workplaces. There are many ways for creating HTML documents and plenty of invisible to user data that carries no information in terms of content. Such circumstances make the automation and visualization process of HTML document comparison rather complex. Introduced algorithm compares versions of HTML documents and displays changes in a result document. The comparison is carried out in such a way that all style and metadata of the document is preserved. Furthermore, the design phases and implementation aspects of the algorithm are investigated in order to share achieved results, to create an effectively working tool and draw guidelines for future work
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
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
