Learning and knowledge building have become critical competences for people in the knowledge society era. In this paper, we propose a sociolinguistic dialogue model for understanding how learning evolves and how cognitive process is constructed in on-line discussions. The knowledge extracted from this model is used to assess participation behavior, knowledge building and performance. The ultima...

Human and contextual factors of information processes need to be integrated into Information Retrieval (IR) models, although often ignored. This article introduces an approach to adapting of an IR system by optimizing the choice of retrieval functions based on user preferences and document features. The framework is provided by MIMOR (Multiple Indexing and Method-Object Relations), a novel appr...

Although the growth of complexity during evolution seems obvious to most observers, it has recently been questioned whether such increase objectively exists. The present paper tries to clarify the issue by analysing the concept of complexity as a combination of variety and dependency. It is argued that variation and selection automatically produce differentiation (variety) and integration (depe...

This paper described recent activities of the Linguistic Data Consortium in the collection, annotation and distribution of language data the developments of tools and standards for using that data, the creation of metadata to facilitate the search for linguistic resources.

Although it prefigures many advances in linguistic theory, the scholarship of nineteenth century scholar Mikołaj Kruszewski is today largely forgotten. In these papers I hope to rectify this situation somewhat by introducing Kruszewski’s insights to modern discourse on phonology. In addition to a detailed summary of Kruszewski’s major work, An Outline of Linguistic Science (Očerk Nauki O Jazyke...

The semantic validation of utterances as true or false is known in logic and linguistics. However, linguistic messages are validated not only on the semantic but also on the pragmatic level. In most linguistic studies, pragmatics is defined mostly as the interrelation between speakers and is considered as a mere supplement to semantics. In our approach (we call MIC : meta-informative centering ...

Although it prefigures many advances in linguistic theory, the scholarship of nineteenth century scholar Mikołaj Kruszewski is today largely forgotten. In these papers I hope to partially rectify this situation by introducing Kruszewski’s insights to modern discourse on phonology. In addition to a detailed summary of Kruszewski’s major work, An Outline of the Science of Language (Očerk Nauki O ...

A potentially fruitful area for applied linguistic research is the nature of the linguistic systems used by second language learners as they learn--or even after they appear to have stopped learning. It has been suggested at various times that the findings of this sort of research would be useful not only to language teachers and textbook writers, but also to our understanding of language conta...
