[Sergio Camiz]

Ho il piacere di comunicare che il Prof. Gastão 
Coelho Gomes, della Universidade Federal do Rio 
de Janeiro, è in visita a Roma fino al 18 luglio 
prossimo e che il 15 luglio alle ore 14 terrà in 
Aula Picone, Dipartimento di Matematica Guido 
Castelnuovo, un seminario dal titolo:

CORRESPONDENCE ANALYSES TO STUDY THE LANGUAGE COMPLEXITY OF TEXTS

The use of quantitative methods, in particular exploratory ones, in
education is continuously increasing, as Textual Analysis is able to deal with
texts as they were common data. Thus, data analysis methods may be used as a
support to education, in particular to understand the most adapt language to
adopt with different kind of pupils, in particular in what concerns their
mentality and their level. In this work, we chose to use a  three-way
contingency table crossing the occurrences of words in four different types
of texts, according to their kind (verb, noun, adjective) and their
structural complexity, to identify differences among texts.
Exploratory Techniques as 1) Simple Correspondence Analysis run on one
marginal two-way table, 2) Multiple Correspondence Analyses and 3) Joint
Correspondence Analyses run on the whole table were used, in order to identify
the true dimension of the problem and its consequences in the interpretation
of the results. After a presentation of both data and proposed exploratory
methods, we will discuss the results of their application on the considered
texts.
