A lexikon kutatása: interjú James Pustejovsky amerikai számítógépes nyelvésszel
No full textJames Pustejovsky az amerikai Brandeis Egyetem Számítástudományi Tanszékének
professzora, a számítógépes nyelvészet és a nyelv ún. lexikon komponensének nemzetközileg
egyik legkiemelkedőbb kutatója. Az 1995-ben megjelent A generatív lexikon [The Generative
Lexicon] c. monográfiája forradalmasította a nyelv szótárkomponensének nyelvelméleti bázisú
kutatását, alapműnek tekinthető nem csupán a generatív szemléletű modellek keretében kutató
nyelvészek körében, hanem a lexikális szemantika és a szintaxis valamennyi kutatója számára
is. Könyvei és tanulmányai idézettségének foka igen magas. Interjúnkban a lexikon kutatásának
minden bizonnyal legavatottabb szaktekintélyét kérdeztük
Extending the Event Calculus with Temporal Granularity and Indeterminacy*
No full textIn many real-world applications, temporal information is often imprecise about the temporal location of events (indeterminacy) and comes at different granularities (Dyreson and Snodgrass 1995). Temporal granularity and indeterminacy are thus emerging as crucial requirements for the advancement of intelligent information systems which have to store, manage, and reason about temporal data. Consider, for example, these events taken from the application-a temporal database for cardiological patients- we are considering in our research (Combi and Chittaro 1999): '‘between 2 p.m. and 4 p.m. on May 5, 1996, the patient suffered from a myocardial infarction’', '‘he started the therapy with thrombolytics in July 1995'', '‘on October 12, 1996, he had a follow-up visit’'. The three events happened at the hours, months, and days timelines, respectively
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
It-TimeML and the Ita-TimeBank: Language Specific Adaptations for Temporal Annotation
No full textThis chapter presents the language specific adaptation of the TimeML annotation scheme to Italian and the creation of the Ita-TimeBank, a language resource composed of two corpora manually annotated with temporal and event information. Particular attention is given to the methodology followed in the development of the corpora: the annotation guidelines document the actual choices done during the annotation and address language specific issues while maintaining adherence to the specifications. The annotation guidelines are supplied with decision tree like instructions and tests grounded in linguistic analysis but theory independent. The results obtained show the reliability of the adaptation of the annotation specifications to Italian and of the methodology used for the creation of the resources
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
