Specification of a Service Oriented Architecture for Advertising Games
No full textA critical issue of distributed systems is concerned with the advertising task. Current solutions require an ex-ante agreement on a common shared language. Although such an approach is feasible from the technological point of view, it is not effective in practice. The process of managing this agreement may present social implications that make the solution difficult to achieve. Recent trends in research propose a new approach based on advertising games where the agreement on a common language is produced at run time. Nevertheless up to now such a model has been studied only through simulations with standalone platforms. We present the specifications of the first web services oriented architecture for advertising game
«Il computer come spazio di osservazione. Un aspetto del progetto SCALE per bambini Down»
No full textIl contributo riporta la relazione tenuta dagli autori al convegno "Il bambino tecnologico", Castiglioncello, 1985, dedicata al Progetto SCALE per bambini Down. Il progetto consisteva nella sperimentazione di un linguaggio informatico specificamente ideato per bambini affetti da sindrome di Down e basato sul linguaggio LOGO. La sperimentazione si è tenuta in collaborazione con l'Associazione genitori bambini Down a Roma negli anni 1983-1984
The DiAGRA User Guide
No full textDiAGRA (Distributed AGgRegator of Annotation) is essentially a component that can be plugged in existing web-servers which provide information on real world items that belong to a fixed domain. Such web-sites generally offer two kinds of services: an item catalog and a item annotation list. The item catalog provides information about items, while the annotation list is a collection of the annotations posted by the users on various items. DiAGRA helps such cooperating web-sites to exchange annotations on items among themselves. This plug-in promotes heterogeneity and specifies the minimal set of requirements needed for interoperability among different servers. Hence it requires very little changes to be done on the web server part.
This document describes the overall architecture of the system which deploys DiAGRA. It then describes the development, deployment and Administration details for successful implementation of such a plug-in. Though the DiAGRA component can be used by web servers of any domain, examples provided in this document refer to the specific domain of ski-mountaineering, where items correspond to ski-route and annotations are posted on ski-trip
Language Games: Solving the Vocabulary Problem in Multi-Case-Base Reasoning
No full textThe problem of heterogeneous case representation poses a major obstacle to realising real-life multi-case-base CBR systems. The knowledge overhead in developing and maintaining translation protocols between distributed case bases poses a serious challenge to CBR developers. In this paper, we situate CBR as a flexible problem-solving strategy that relies on several heterogeneous knowledge containers. We introduce a technique called language games to solve the interoperability issue. Our technique has two phases. The first is an eager learning phase where case bases communicate to build a shared indexing lexicon of similar cases in the distributed network. The second is the problem-solving phase where, using the distributed index, a case base can quickly consult external case bases if the local solution is insufficient. We provide a detailed description of our approach and demonstrate its effectiveness using an evaluation on a real data set from the tourism domai
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
