This book is about syntactic databases (a.k.a. treebanks), collections of text material in which the syntactic relations have been made visible. It starts off with a general intro-duction to the subject and then continues with three in-depth investigations of more specialized aspects.
In the introduction, syntactic databases are first placed in the larger context of linguistic databases, text collections with a broader linguistic annotation than just a syntactic one. Then some examples of syntactic databases are given, illustrating the range of annotation actually...

The subjects found in this book represent a cross-section of current research topics in computational linguistics and are related to the fields of grammatical description, statistical modelling and natural language technology. Grammatical description is included in the form of work on HPSG, both the application of HPSG and investigation of the structure of HPSG itself. Another popular methodology, statistical modelling, is amply present as well: there are papers on the use of statistical models in such varied areas as language evolution, phonotactics, index term identification and bilingual...

In both the linguistic and the language engineering community, the creation and use of annotated text collections (or annotated corpora) is currently a hot topic. Annotated texts are of interest for research as well as for the development of natural language pro- cessing (NLP) applications. Unfortunately, the annotation of text material, especially more interesting linguistic annotation, is as yet a difficult task and can entail a substan- tial amount of human involvement. Allover the world, work is being done to replace as much as possible of this human effort by computer processing. At the...
