MONTRA: An agile architecture for data publishing and discovery
Full text linkData catalogues are a common form of capturing and presenting information about a specific kind of entity (e.g. products, services, professionals, datasets, etc.). However, the construction of a web-based catalogue for a particular scenario normally implies the development of a specific and dedicated solution. In this paper, we present MONTRA, a rapid-application development framework designed to facilitate the integration and discovery of heterogeneous objects, which may be characterized by distinct data structures.publishe
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Análise do Impacto Visual da Montra no Comportamento do Consumidor Utilizando Ferramentas de Data Mining
Full text linkAnálise de Dados e Sistemas de Apoio à DecisãoMaster in Data Analysis and Decision Support SystemsA Análise de Dados e a Extracção de Conhecimento de Dados são ferramentas que têm ganho cada vez maior relevância, dado que a quantidade de dados que temos à disposição é cada vez maior e a importância que estes dados assumem na tomada de decisão é crucial.
O presente trabalho tem assim por objectivo aplicar a análise e extracção de dados à análise do poder de atracção da montra nos potenciais consumidores. Assim propomo-nos a usar a ferramenta das Árvores de Decisão, para analisar em que medida o comportamento dos consumidores é ou não influenciado pela montra, isto é, em que medida o consumidor entra na loja e compra em resultado do poder de atracção da montra. Como os dados em estudo foram recolhidos na época de saldos e na época da nova colecção propomo-nos também a analisar em que medida o poder de atracção da montra e a sua influência no comportamento do consumidor é diferente consoante se está ou não na época de saldos.
Pretende-se com este trabalho contribuir para um melhor conhecimento deste instrumento de comunicação que todos os retalhistas têm à sua disposição, e assim contribuir para que retirem da montra a maior rentabilidade possível.Data Mining and Knowledge Discovery from Data are tools that have attracted a great deal of attention in recent years, since every day the amount of data stored increase and tall his data is crucial to management decisions.
The goal of the present dissertation is to apply the data mining and the Knowledge Discovery from Data to the analyses of the power that a store window may have to pick up potential buyers. So this work will use the classification to find a model that describes and distinguishes data classes. This model will be represented in the form of decision trees. With this method we will be able to analyze how the behavior of the potential buyers is a consequence of the store window: we want to know if a person goes into the store and buy products as a consequence of the influence of the store window.
The data that will be analyzed was collected in the sales season and when the store already presented products of the new season (Fall-Winter). So we also pretend to analyze if the store window as different influence in the potential buyer in this two different moments of time, were different collections are presented in the store.
With this Job we will contribute for a better knowledge of the store window as an important instrument of communication, available for all managers of the retail industry, and so help them to obtain the best profitability possible with this instrument
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
