Introduction

The necessity to study language use in computer-mediated communication (CMC) appears to be of common interest, as online communication is ubiquitous and raises a series of ethical, sociological, technological and technoscientific issues among the general public.

I recently presented a paper at the third LRL Workshop (a joint LTC-ELRA-FLaReNet-META_NET workshop on “Less Resourced Languages, new technologies, new challenges and opportunities”).

Moreover, there are diverse and partly unknown search biases related to search engine optimization tricks and undocumented PageRank adjustments, so that diverse sources of URL seeds could at least ensure that there is not a single bias, but …

While there are indubitably clear cases such as lists of addresses or tag clouds, it is not always obvious to define how extensive the notions of text and corpus are. What’s more, a certain amount of documents just end up too close …
