Knowledge Query and Manipulation Language: A Review
No full textKQML is a protocol designed to support communication between software agents. A distributed system architecture based on software agents is intended as a solution to problems inherent in the client-server model. This report summarises the communication needs of software agents, and shows how KQML meets those needs. Whereas early versions of KQML were unusable because they lacked properly-defined semantics, the most recent specification of the protocol includes formal definitions of its semantics. This report identifies a minimal subset of KQML which meets the essential communication needs of agents, and examines the semantics of that subset. The report is illustrated by examples of agent interactions using KQML. 2 1 Introduction The Knowledge Query and Manipulation Language (KQML) is a new communication protocol designed as part of the US Knowledge Sharing Effort (KSE) to support runtime interaction and knowledge sharing among intelligent software agents [3].

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
Semantic grid tools for rural policy development and appraisal
No full textThe project will assist the social science community to exploit the full potential of emerging Semantic Web technologies and standards in the Grid context. It will expand upon an earlier ESRC-funded pilot demonstrator project at Aberdeen (Fearlus-G[1]) to explore the costs and benefits of using proposed Semantic Grid standards and methodology in tasks related to policy development and appraisal. Aims of the Node are as follows: To facilitate evidence-based rural, social, and land-use policy-making through integrated analysis of mixed data types, with the goal of enabling the achievement of greater sustainability through cross-sectoral policy-making; To demonstrate that Semantic Web/Grid solutions can be deployed to support various facets of evidence-based policy-making through the development of appropriate tools; To focus on the authoring of relevant ontologies to support rural, social and land-use policy domains; To investigate issues surrounding communication of semantic metadata to social scientists and policy practitioners; To promote awareness of the Semantic Grid vision and supporting technologies amongst social scientists, and to facilitate training through workshops, etc.; To foster interdisciplinary research between social and computing scientists
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
