The aim of this research is to investigate, through textual analysis, which one of the three kinds of informative products taken into consideration, produces an effect (di riutilizzo) of characteristics terms of the information recived.
In detail, the study will focus on the identification of what typology of informational product will lead the user to riproduce words and keywords previously read in the informational material.
All the informative materials have been created to promote pro-environmental attitudes and behaviours that can improve the environmental quality of our communities and our places.
All of them are concerned on renewable energies.
The research of informative materials has been made on web and with study in the field ( Ecoistituti Italiani, Enti per la comunicazione ambientale).
The Cd-Rom RiduCO2 (Picture 1), a software produced by ‘Ecoistituto Pasquale Cavaliere’ in Torino, presents an emissions’ calculator based on the principle of tailoring. The software RiduCO2 has been compared to hypertextual informational product and flyers.

The textual analysis has been carried out with the software SPAD.t to study the peculiar terms applying the ASPAR procedure.
First of all, it is necessary to apply the ASPAR methodology to the RiduCO2, to obtain a graphical rappresentation of the most common terms used to describe different kinds of renewable energies.
The ASPAR analysis will consider one variable (renewable sources) and its five different illustrative modalities.
The same procedure of analysis is repeated for all the three informative materials.
Following the graphical rappresentation of the informative materials’ content, it should be possible to create a questionnaire with both explorative and open questions, asking to the users of the informative material to describe the object of information illustrated by that material.
The last step was to test the three informational products on three groups each one composed by ten persons ( first group software, second group hypertext, third group flyers) and subsequently submit the questionnaire to them.
The last analysis consists to apply the ASPAR procedure to the response corpus.


The comparison between the graphical rapresentations of informative materials corpus with the rappresentation of response corpus of users shows that when the informative products present interaction the effect of reuse of words and keywords previously read in the informational material is more strong.
