: Many computer-assisted language learning systems specifically designed to be used in the curriculum and which exploit AI techniques have neither a learner model nor consequently any deep error analysis. Evidence from applied linguistics shows that learners have their own system of rules for the production of a foreign language. We believe the central issue is to determine the appropriate level of description of these rules and uncover the strategies used by the learners in particular situations. This information represents the major part of the learner model. We review error analysis in second language learning and tutoring systems related to this perspective. We introduce a new structure, called an "applicable rule", that can be used to help diagnose and to represent a learner's performance. We propose a design for the architecture of a system for computer diagnoses of learners' grammatical performances in a communicative environment. Examples of diagnosis using applicable rules ill...

The problems of shared access to large bodies of information raise difficulties in the understanding and semantics of concurrency, distribution and stability. When the information is held in a persistent object store, these difficulties of understanding are extended to the interaction of the concepts of persistence and store with those above. Some of the difficulty is in deciding at what level the architecture or language operates, be it hardware or software. Other difficulties arise in the complexity of the problems of concurrency. In this paper we identify these difficulties and clarify them with regard to database programming language design. We propose a model of concurrency that may be used as a solution to the problems. It is based on the rendezvous of Ada and integrated with a polymorphic type system with inheritance. This yields a process-oriented approach to system construction that has much in common with the object-oriented approach. We will demonstrate the facilities of the language Napier which allows the integration of these two methodologies along with a persistent
