Information technology has seen radical changes in the last two decades with systems to support cooperation and communication playing an ever- increasing role. Communication is the key to smooth cooperation.
Individuals working in groups coordinate their actions though communication.
Communication modelling has been studied for more than two decades. LAP became popular in the 80s and a second wave of frameworks, models and systems emerged in the 90s. As diverse as these application of LAP are, they all have in common the fundamental agreement that language is not only used for exchanging information as in reports, statements etc. The conventional perspective on information systems stresses the contents of messages rather than the way they are exchanged. In contrast, the Language-Action Perspective emphasises what people do by communicating, how language is used to create a common basis for communication partners, and how their activities are coordinated through language.
