Traces of the idea of verbal valency structure in nineteenth-century grammars – This paper aims to show how K.F. Beckers’s notion of “subjektive” and “objektive Verben” (i.e. those always used with an “ergänzende Objekt”, a ‘completive object’) is a rough forerunner to the modern idea of dependency grammar. In Italy, this theoretical core was assumed by Raffaello Lambruschini in 1840 (and, after him, by the basic school grammar La grammatica del mio Felicino written by Ulisse Poggi, 1865, 18722), but with a huge trivialisation: subjective verbs were identified with intransitive verbs and objective verbs with transitive ones.
In this article, we present a comprehensive measurement system to determine the level of user emotional arousal by the analysis of electrodermal activity (EDA). A number of EDA measurements were collected, while emotions were elicited using specially selected movie sequences. Data collected from 16 participants of the experiment, in conjunction with those from personal questionnaires, were used to determine a large number of 20 features of the EDA, to assess the emotional state of a user. Feature selection was performed using signal processing and analysis methods, while considering user declarations. The suitability of the designed system for detecting the level of emotional arousal was fully confirmed, throughout the number of experiments. The average classification accuracy for two classes of the least and the most stimulating movies varies within the range of 61‒72%.
