ILES stands for Information, Written and Signed Language. ILES specifically addresses the analysis,
understanding and production of written language, and the modelling and production of signed language.
Natural language processing aims to process human language in such a way that the results of this
processing make sense for humans, i.e., meet their expectations. It aims to design computer programs that
can understand or emulate human communication, e.g. by analysing documents and extracting task-relevant
information, helping in the production of documents (spell checkers, style checkers, controlled language
editors), generating a whole document (text summarizer), or answering questions based on text or more
This motivates fundamental and applied research topics among which ILES addresses the following:
- A fundamental language processing function consists in knowing when two expressions have
the same meaning.
- Because language is a means to convey information, searching and extracting information from
language data is an important task.
- Sign language processing addresses a stringent societal demand; it requires fundamental modelling
work and methods to generate realistic signed productions.
