Abstract: Dans des échanges parlés entre des individus dont les niveaux de maîtrise d'une langue sont disparates, on contrôle les échanges partant des individus maîtrisant le mieux la langue de façon à rester à un niveau accessible aux individus maîtrisant moins bien cette langue. Ainsi, les échanges partant d'un locuteur autochtone à destination d'un élève apprenant la langue du locuteur autochtone (la langue cible) sont surveillés au moyen d'une interface et comparés à un modèle conservé en mémoire et représentant les connaissances et aptitudes de l'élève par rapport à la langue cible. S'il s'avère que le locuteur autochtone s'exprime d'une façon susceptible de ne pas être comprise par l'élève, par exemple en cas d'utilisation de vocabulaire ou de structure de phrase dépassant les aptitudes de l'élève, l'interface le signale au locuteur autochtone. L'interface a alors la possibilité de suggérer au locuteur autochtone un autre mot ou une autre structure de phrase, de façon à l'inviter à s'exprimer autrement. Le locuteur autochtone peut alors y substituer un autre mode d'expression et l'envoyer.

Filed: 2008-12-29
Abstract: A terminal device acquires item property information from a medium, and transmits, to a server device, terminal identification information of the terminal device, which is assigned by the server device in advance and stored in storage means and item property information acquired from the medium. The server device stores the terminal identification information and the item property information received from the terminal device, and transmits, to a device, information generated based on the terminal identification information and the item property information received from the terminal device. The server device performs authentication of a user of the terminal device based on the terminal identification information. Because this terminal identification information is assigned by the server device, transmission of the information does not entail a risk of leakage of personal information, unlike a case in which personal information such as a telephone number is used for authentication.
