Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Interpreting Complex Noun Phrases in Mandarin Chinese
No full text231 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1997.It has been observed that word order and intonational prominence in MC NPs tend to correlate with definite and indefinite readings of the NPs. Based on recurring interpretive patterns in MC, I show that in MC, definite readings are expressed by lexical and constructional meaning, the interpretation of focus, and contextually furnished constraints jointly in a systematic way. More specifically, ordering MOD-de before DEM/NUM (i.e., adjoining MOD-de to NP) indicates focus on MOD-de and a presupposition that the focus-induced alternative set associated to the resulting NP encodes cardinality information regarding the set of contextually relevant entities satisfying the descriptive content of the NP. The extensional content of an expression, which I treat as the 'purely truth-conditional' aspect of meaning interpretation, may be computed compositionally in regular model-theoretic terms and could be the same for definite and indefinite NPs, for demonstrative NPs with regular or more stringent requirements on the set in which uniqueness must hold, and for quantificational NPs with optional vs. obligatory de re readings. The interpretive differences observed of such NPs follow presuppositions (introduced by DEM and by adjoining MOD-de to NP) coupled with focus-induced alternatives associated to the NPs. Crucially, the presuppositions together with the alternatives associated to the NP systematically restrict the contexts (i.e., Models) in which the NP may be used felicitously, and the observed interpretive differences fall out.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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

A Grammar of *Case: The Head of a Semantic Filler, but a Nominative Morpheme
No full text185 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2000.The dissertation proposes an explicit and general analysis of case, which is extendable to the analyses of the syntax and semantics of the topic morpheme, and the "topic-like" nominative morpheme in Japanese. A case phrase, e.g., a nominative phrase, in general is analyzed as adjoining to a predicate and specifying a particularly case-registered argument of the predicate as identical to its complement. New data concerning coordination among case phrases or topic phrases are offered in order to argue for the grammar of case and against the standard theory of case (that case phrases are subcategorized for by predicates and topic phrases are adjuncts). In the theory of case, semantics takes care of associations between nouns and arguments, for example, eliminating a valence specification if its content is specified as an argument. The theory of case is implemented on parsing system unicorn3, which had been developed at University of Illinois at Urbana-Champaign.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
