This paper relates an experimentation of a collaborative e-learning system. In this kind of system, tracks arising from communication tools allow to build useful indicators for all system actors. We show how tracks are analyzed and how this analysis is useful for reengineering purposes.

We study the annotation of the Prague Dependency Treebank 2.0 (PDT 2.0) and assemble a list of requirements on a query language that would allow searching for and studying all linguistic phenomena annotated in the treebank. We propose an extension to the query language of an existing search tool Netgraph 1.0 and show that the extended query language satisfies the list of requirements. We demons...

The chewing of betel nut is prevalent throughout the Asia-Pacific region, especially in the Pacific subregion. Consumed for its stimulant properties, there is concern over this habit’s association with negative health consequences. The present study examines the case of Honiara in Solomon Islands where the prevalence of betel nut consumption has increased in recent years, especially among schoo...

A semi-automatic syntactic annotation of a part of the Czech National Corpus in the Prague Dependency Treebank (PDT) has among its aims the possibility to check the theoretical approach chosen (Functional Generative Description, see [2]). While the first phases of the annotation of PDT, i.e. the morphemic representations and the dependency trees on an intermediate analytic level, i.e. analytic ...

There is no doubt that the author succeeds in both these objects, and he gives a most interesting and instructive set of chapters ranging in s...
