L’evidenza morfologica nell’era digitale: per un’integrazione di teoria e computazione
No full textThis article proposes a research perspective on morphological and lexical data based on an integrated approach that merges linguistic theory and computational analyses of a large quantity of textual data. Starting from a description of the units and processes of morphology, and of the issues they raise, we discuss to what extent these theoretical notions can be translated into the algorithmic procedures of Natural Language Processing (NLP) and what resources and methods are nowadays available to make morphological and lexical knowledge explicit within texts. At the same time, we explore the repercussions that the application of computational (but also psycho-/neuro-linguistic) techniques may have on our theoretical representations and on their plausibility
Context-sensitivity and linguistic structure in analogy-based parallel networks* *All the ideas illustrated in this paper are the outcome of a cooperative effort: nevertheless, for the specific concerns of the Italian Academy, Vito Pirrelli is the author of the sections 1, 4 and 5, Stefano Federici of sections 2 and 3.

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
Review of Young & Bloothooft (1997): Corpus-based Methods in Language and Speech Processing
No full textMAGIC - Generated Lemmatized Forms
No full textThe resource contains a list of lemmatized forms generated by MAGIC, a morphological analyzer developed at the Institute of Computational Linguistics by Vito Pirrelli and Marco Battista. The morphological generator, one of the modules of the tool, takes a list of lemmas and produces an output that includes: a reference lemma, forms generated based on heuristics, part of speech (POS), and morphological features attributed to the form.
The generated output consists of a series of linguistic objects called "words," encoded in the form of a Macro (the 'word' macro), without morphological restrictions. The generated forms do not include information related to segmental or suprasegmental (stress position) phonology
