No full textTyt. z nagłówka.Bibliogr. s. 30-31.Algorytmy przetwarzania języka naturalnego mają duże zapotrzebowanie na zasoby komputerowe, szczególnie gdy wymagane jest dostosowanie algorytmu do języka fleksyjnego jakim jest np. język polski. Artykuł przedstawia wymagania czasowe i pamięciowe algorytmów tagowania częściami mowy oraz algorytmów klasteryzacji zastosowanych do dwóch korpusów języka polskiego. Dokonano benchmarkingu algorytmów na trzech platformach wysokiej wydajności reprezentujących różne architektury. Dodatkowo porównano wersję sekwencyjną oraz implementacje OpenMP algorytmów klasteryzacji.Natural Language Processing algorithms are resource demanding, especially when tuning to inflective language like Polish is needed. The paper presents time and memory requirements of part of speech tagging and clustering algorithms applied to two corpora of the Polish language. The algorithms are benchmarked on three high performance platforms of different architectures. Additionally sequential versions and OpenMP implementations of clustering algorithms were compared.Dostępny również w formie drukowanej.SŁOWA KLUCZOWE: benchmarking, tagowanie częściami mowy, klasteryzacja dokumentów, przetwarzanie języka naturalnego.

Mobile social networks for live meetings
No full textTyt. z nagłówka.Bibliogr. s. 99-100.In this article, we present an idea of combining social networking websites and modern mobile devices abilities to transfer social networking activity to a higher level. Nowadays, these devices and websites are used to offer ability of remote communication (phone calls, message exchange etc.), which potentially can be used to notify people about meetings in the real world. Since the current social network models do not provide enough information for such notification (social networking websites are examples of social networks) a new social network model that will be suitable for the above mentioned application is proposed and a new social platform that base on mobile devices is introduced. This platform can notify users when their friends are nearby. The paper presents the model and the simulation that verifies the approach.Dostępny również w formie drukowanej.KEYWORDS: social networks, social networking websites, mobile devices
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
Agent-based monitoring using fuzzy logic and rules Agentowe podejście do monitoringu wykorzystujące logikę rozmytą oraz reguły/
No full textTyt. z nagłówka.Bibliogr. s. 112-113.W pracy przedstawiono system agentowy, który pozwala na monitoring rozproszonych systemów. Każdy agent posiada własną wiedzę na temat możliwych reakcji na zaobserwowane sytuacje, np. awarie. W artykule przedstawiamy koncepcję automatyzacji monitoringu nazwaną SAMM compliant Agent. Jest ona rozszerzeniem systemu SAMM. Do opisu wiedzy użyte zostały zbiory rozmyte, a także reguły, przy czym reguły używane są do określenia prostych czynności, które może wykonać dany agent. W zaimplementowanej wersji reguły służą jako statyczna wiedza, natomiast logika rozmyta została wykorzystana jako główna idea reprezentacji wiedzy w przedstawionych agentach, z których każdy zarządza swoim segmentem wiedzy i może swoją wiedzę przekazywać innym agentom.In this paper we present two solutions ofmonitoring automation for distributed systems. We develop this system to automate monitoring of distributes systems. Both solutions are aimed to monitor data storage and web services like web page servers. The first solution implemented in a system called Saude-Net, is an rule-based top level monitoring tool. In this system there are implemented rules which provide conditions which refer to one or more measured values. This system is able to choose the best action for an observed situation, e.g. a failure. It is possible to define more than one rule which relate to the same monitoring resource. The second concept presented in this paper refers to a fuzzy logic agent based approach to network monitoring. It is called SAMM compliant Agent. It is an extension to the Semantic-based Autonomous Monitoring and Management system (SAMM). On the one hand, it uses rules to define simple actions, based on a simple condition and an action description. On the other hand the main knowledge of this solution is defined by fuzzy logic. This system is able to manage and modify its knowledge to better fit to monitored resources. The knowledge in this concept is distributed among all the agents. The agents residing on a different hosts handle their parts ofthe knowledge and are capable to share/exchange them.Dostępny również w formie drukowanej.SŁOWA KLUCZOWE: monitoring, logika rozmyta, systemy regułowe, agenci, automatyzacja.

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
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
