The UVAL group, led by Janet-Ann Decesaris, studies linguistic variation (both within the group and in the individual) and linguistic change, as inherent phenomena to natural language, and as well as their effects on our understanding of different linguistic dimensions and their implications for improving the design of linguistic applications. This variable nature of human language affects all linguistic levels as well as the rules governing linguistic behaviour and communicative interaction.
UVAL studies three dimensions of linguistic variation:
- Language variation within the group,
- Variation within the individual
- Sociodemography of language
