    Contains fulltext : 40165.pdf (Publisher’s version ) (Open Access)This thesis introduces a model for knowledge representation as a sign recognition process, on the basis of an analysis of the properties of cognitive activity. By offering a logical account of this model, the existence of a `naive' logic underlying human information processing is revealed, which in turn opens the way towards a Peircean semiotic characterization of the cognitive model. `Naive' logic is a procedure generating relations between collections of qualia, in the sense of agreement, possibility, and (relative) difference. It is suggested that those relations have common meaning aspects shared with Boolean relations on two variables. The close relationship between the process model of cognitive activity on the one hand, and the Peircean signs on the other enables the cognitive model to be interpreted as a meaningful process, and the Peircean classification of signs as a process, generating meaning aspects or parameters of (meaningful) interpretation. In conformity with the fundamental nature of cognitive activity, it is suggested that the process model of cognitive activity may be uniformly applied for modeling different knowledge domains. This hypothesis is tested for the domain of `naive' logical, syntactic, semantic syntactic, reasoning and mathematical symbols. Each of these models consists in a specification of a recognition process (parser) and a definition of combinatory properties of primary entities (lexicon). An advantage of the proposed theory is that adjustments of the model of a domain, for example, in order to cope with new phenomena, may only require an adjustment of the lexicon, not the parser, which can be invariantly used. An advantage of uniform knowledge representation is that it may reduce the hard problem of merging complex signs obtained in different domains to the more simple task of structural coordination. Such a representation is used in this thesis for the definition of a technique for text summarization.Radboud Universiteit Nijmegen, 13 april 2008Promotor : Weide, T.P. van der209 p

    169. London, British Library, Additional 40165 A Cyprian, "Epistolae" (fragments); "OE Martyrology" (fragment) (fragmentary flyleaves from a monastic miscellany, Add. 40165B) [Ker 132, Gneuss 297/298, Lowe 2.178] HISTORY: Add. 40165 A.2 is of A-S provenance (Wessex?), a late 9c or early 10c fragment of the "OE Martyrology" (on date see Kotzor 1981: 1.116*), a cut-down bifolium once serving as flyleaves, along with the remains of a quire from a late 4c copy of Epistles of Cyprian ( bishop of Carthage, d. 258), also of A-S provenance (Add. 40165 A.I), in a 12c monastic miscellany (Add. 40165 B). The volume was purchased by the B.M. from Sotheby's , 12 Dec. 1921 ( Lot 504) and the older elements removed by B.M. A printed bookplate on a modern flyleaf in Add. 40165 B says it was "bequeathed by the will of [Bernard] Edward [Howard, 12th] Duke of Norfolk (d. 1842) to remain in his family. Henry Howard & the Eyre Esq., Executors:' The former flyleaves were bound separately as ff. 1-7 in a modern portfolio in 1947. See the description to B.L. Cotton Julius A. x [200) for the history of the "Martyrology:' [Note: The assemblage was removed from its medieval cover when accessioned to the B.M., allowing the Cyprian to be rearranged as far as possible according to its original disposition. The old leather cover is kept separately (shelfmark SAL Cup'd 118 a). It is a thick white leather cover, now brown on outside; total area front and back is 270 x 178 mm., with an inner leather spine reinforcement about 37 mm. wide and 175 mm. high. It was not a binding, but a folder or portfolio to which the flyleaves were sewn, the pattern of sewing holes on front cover matching the pattern of holes on f. 2. The front is 175 x 130, back is smaller , about 120 mm. wide from spine to fore-edge. Inscribed on front cover in black ink, early 13c, 'lib<er> iste | Glos [ ....s ]up(er) Cantica | [ ....] 7 alia multis | sententia s(un)t [ ........] | lib[ ... ]'.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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
