Linguistic and
Cultural Diversity
in the Internet


The Observatory of the Linguistic and Cultural Diversity in the Internet (OBDILCI) is a non-profit organization that researches the presences of languages and cultures online. Since 1998, we have developed methodologies to conduct this research, which have evolved to keep up with the changes in the Internet. Our work is peer-reviewed and we are the only organization dedicated solely to this work, and as such, our data is the most reliable and in-depth.
