Abstract

It is a surprising fact that; despite the existence of various mature Natural Language Processing (NLP) tools and resources that can potentially benefit language learning; very few projects are devoted to development of Intelligent Computer-Assisted Language Learning (ICALL) applications. This paper presents an on-going collaborative project whose overall aim is to develop an opensource system architecture for supporting ICALL systems that will facilitate re-use of existing NLP tools and resources on a plug-and-play basis. The two language teams – Icelandic and Swedish – have tested the architecture design by implementing two ICALL applications which convincingly show how principles defined by Service-Oriented Architecture (SOA); with web services as implementation technology; can benefit re-use of existing NLP components in ICALL applications. This paper introduces the project; provides the theoretical and practical background; describes the different paths adopted within the two language teams; and presents the first results.
