Trade-off between complexity of structured tagging and effectiveness of Web service retrieval
No full textSearching for services often starts from the exploration ofthe service space. Community generated tags can support exploration of this space. Researchers attracted by the community-available “free manpower” proposed more complex tagging-based annotation models.Those models tag specific parts of the Web service definition: single operations, as well as inputs and outputs of those operations. However, there is no evidence whether effort spent on annotating complex structures is justified by the performance improvement of retrieval based on those annotations. In this paper we apply similarity-based search to find a trade-off between retrieval effectiveness of existing annotation modelsand the annotation effort
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
WSCOLAB: Structured collaborative tagging for Web service matchmaking
No full textA key driver for Service Oriented Architecture implementations is the hope to save development time and costs through a higher degree of reuse of readily deployed Web services. To achieve this goal, it is necessary to make services discoverable. Current approaches use authoritatively defined taxonomies to categorize services, which simply does not work for the flood of services being published on the Web in uncoordinated manner. Collaborative tagging claims to address this problem, because it is the process by which many users add metadata in the form of keywords to shared content (Golder and Huberman, 2006). However, it suffers from the lack of structure to describe Web service interfaces. We introduce structured collaborative tagging classification schema that can provide Web service descriptions for both categorization and interface matchmaking approaches. We report an experiment where 27 taggers have used our classification schema to annotate 50 Web services from Jena Geography Dataset. We also propose a single-request Web service matchmaking technique based on the proposed classification schema. The performance of the proposed technique has been confirmed by the first position awarded in the Cross-Evaluation track of the Semantic Service Selection 2009 contest against other matchmaking approaches. It shows that our classification schema is simple and powerful enough to be used by both tagging and querying end-users
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
Visually Enhanced Python Functions for Clinical Equality of Measurement Assessment
Full text linkEquivalence testing requires specific procedures usually provided by specialized statistical software. The proposed package includes customized methods to assess biomedical equivalence and focuses on translating the outcomes into visual reports. The functions are coded in an object-oriented framework, contain improved plots or novel graphs to facilitate interpretation of the results, and are accompanied by console textual outputs to support users with additional explanations. Special attention has been devoted to verifying the preliminary assumptions of the statistical tests with automatic routines. The current module covers four aspects of biomedical statistics (equivalence, Bland--Altman and ROC analyses, effect size, and confidence intervals interpretation), offering these methodologies to the biomedical community as accessible stand-alone functions. The manuscript defines software's functions and innovations with examples and theoretical explanations.@inproceedings{FedCSIS202232,

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
