Cursusbeschrijving
[ Top | Cursus | Literatuur | Werkcollege | Tentamen ]

Aim of the course is to provide an introduction to repositories of linguistic data, by focussing on: annotated corpora (i.e., written and spoken), linguistic databases and computational lexicons.

Corpora represent a collection of texts which are usually annotated with part of speech and morphological information. They often encode syntactic and phonological information. Linguistic databases are usually oriented towards the description of specific phenomena either by means of examples with glosses or by means of variables. Computational lexicons are repositories of linguistic information for use in language processing applications.

Special attention will be dedicated to the techniques and to the standards which should be adopted in order to develop linguistic resources. In particular, the course will look at different types of corpora and will focus on the various levels of annotation with hands-on sessions on the Corpus of Spoken Dutch. Different types of databases will be discussed and various techniques to design linguistic databases will be presented. Furthermore, attention will be dedicated to Wordnet, as a different way to conceive lexical annotation whose design is inspired by current psycholinguistic theories of human lexical memory.

Issues concerning the archiving of linguistic resources on the web, including metadata standards (serving as finding aids) will be addressed and current initiatives will be presented. Furthermore, issues related to the digital encoding of language data will be discussed including standards such as XML.

The course will also focus on possible uses of language resources among which: linguistic research, development of new human language technologies and as teaching aids.

Algemene thematiek:

Corpora, databases, wordnet, annotation tools, standards for linguistic resources, metadata.
