La République et la question scolaire : quelle légitimité pour une école en crise ?
2007
Le «sentiment» comme facteur sémantique : la «sémantique représentationnelle» entre la «linguistique psychologique» et le formalisme
2016
Psychological linguistics - Heymann Steinthal in Germany (1823-1899) and Aleksandr Potebnia in Russia (1835-1891) - has borrowed from the psychology of its time the model of “representative semantics” according to which meanings are representations (Vorstellungen) connected to words. Within this frame, “feeling” (Gefühl) or “feeling tonality” belongs to the verbal representation, in particular to the semantic mechanism. This is also the case of Karl Otto Erdmann’s (1858-1931) semantics which distinguishes within the meaning a “secondary meaning” (Nebensinn) and a “value of feeling” (Gefühlswert). Within the formalist approach (it deals with the “Russian formalism”, 1914-1929), the analysis …
La educación de la mujer en el franquismo y su evolución en Valencia (1951-1970)
1993
El nacional-catolicismo cuenta entre sus principios ideológicos con la separación estricta de la sociedad en razón del género. Este constructo atraviesa y determina toda la organización social y, como parte de ella, el aparato educativo. Existirán dos maneras de educar a los ciudadanos según se trate de hombres o mujeres. Se trata de realizar un seguimiento y análisis de la evolución de la educación de las mujeres durante el franquismo en la etapa histórica del predesarrollismo y el desarrollismo que comprende la que como colectivo recibieron (educación de las mujeres) y la destinada a modelarlas según unos estereotipos determinados (educación como mujeres). Cabe destacar que no existe un ú…
A Layered Architecture for Sentiment Classification of Products Reviews in Italian Language
2017
The paper illustrates a system for the automatic classification of the sentiment orientation expressed into reviews written in Italian language. A proper stratification of linguistic resources is adopted in order to solve the lacking of an opinion lexicon specifically suited for the Italian language. Experiments show that the proposed system can be applied to a wide range of domains.
Sabiedrības attieksmes modelēšana, izmantojot sentimenta analīzi
2017
Šī darba mērķis ir izveidot sentimenta analīzes risinājumu, kuru paredzēts izmantot informācijas ieguves sistēmas koncepta izstrādē. Sentimenta analīze tiks veikta sociālo tīklu ziņām. Darba izstrādes sākumā tika veikta esošo sentimenta analīzes risinājumu izpēte un to rezultātu salīdzināšana. Tālāk tika veikta publiski pieejamo treniņdatu korpusu ievākšana. Papildus iegūtajiem datiem, tika izveidots latviešu valodai paredzēts sentimenta analīzes treniņdatu korpuss. Korpusa izveidošanas procesā tika veikta informācijas ieguves sistēmas koncepta izveide. Pēc nepieciešamo treniņdatu savākšanas, tika veikta ilgās īstermiņa atmiņas rekurentā neirona tīkla izveidošana un optimizēšana. Darba rezu…
Positionless aspect based sentiment analysis using attention mechanism.
2021
Abstract Aspect-based sentiment analysis (ABSA) aims at identifying fine-grained polarity of opinion associated with a given aspect word. Several existing articles demonstrated promising ABSA accuracy using positional embedding to show the relationship between an aspect word and its context. In most cases, the positional embedding depends on the distance between the aspect word and the remaining words in the context, known as the position index sequence. However, these techniques usually employ both complex preprocessing approaches with additional trainable positional embedding and complex architectures to obtain the state-of-the-art performance. In this paper, we simplify preprocessing by …
Fearscapes. Sentimenti di paura, retoriche sulla sicurezza e pianificazione urbana nella città contemporanea
2012
La ricerca Fearscapes affronta l’analisi delle relazioni tra sentimenti di paura – connessi al pericolo di essere vittime di crimine nello spazio urbano –, discorsi di paura – testi diretti alla generazione di sentimenti di paura –, politiche e pratiche urbane, forme spaziali della città contemporanea. A partire dagli anni ‘90, nelle città occidentali, ad una diminuzione dei volumi di criminalità corrispondono accresciute sensazioni di insicurezza. Nella convinzione che esista un uso strumentale dei discorsi di paura per giustificare politiche e pratiche, Fearscapes analizza, dal punto di vista della pianificazione urbana, questioni come le politiche urbane di sicurezza, processi di fortifi…
Can you feel it will you tell me. Encouraging sentiment expression on the web
2015
In a recent trend in web communication, news outlets and blog platforms allow readers to express opinions about what they have read by choosing an associated feeling, or sentiment ex- pression. This emerging trend, fitting between liking and full text comments, has not still found the popularity it should. The thesis of this paper is that this is also due to the way the sen- timent choice is presented to the user. In order to test this hy- pothesis we have devised a pilot experiment; results confirm that a simpler way of choice increases sentiment expression and yields result that are more aligned with ground truth.
A Novel Approach for Supporting Italian Satire Detection Through Deep Learning
2021
Satire is a way of criticizing people (or ideas) by ridiculing them on political, social, and morals topics often used to denounce political and societal problems, leveraging comedic devices such as parody exaggeration, incongruity, etc.etera. Detecting satire is one of the most challenging computational linguistics tasks, natural language processing, and social multimedia sentiment analysis. In particular, as satirical texts include figurative communication for expressing ideas/opinions concerning people, sentiment analysis systems may be negatively affected; therefore, satire should be adequately addressed to avoid such systems’ performance degradation. This paper tackles automatic satire…
A Study on Classification Methods Applied to Sentiment Analysis
2013
Sentiment analysis is a new area of research in data mining that concerns the detection of opinions and/or sentiments in texts. This work focuses on the application and the comparison of three classification techniques over a text corpus composed of reviews of commercial products in order to detect opinions about them. The chosen domain is about "perfumes", and user opinions composing the corpus are written in Italian language. The proposed approach is completely data-driven: a Term Frequency / Inverse Document Frequency (TFIDF) terms selection procedure has been applied in order to make computation more efficient, to improve the classification results and to manage some issues related to t…
