Introduction
CELEX2 contains updated versions of the CELEX lexical databases of English (Version 2.5), Dutch (Version 3.1) and German (Version 2.0) developed by the University of Nijmegen, the Institute for Dutch Lexicology in Leiden, the Max Planck Institute for Psycholinguistics in Nijmegen, and the Institute for Perception Research in Eindhoven.
For each language, this data set contains detailed information on:
- orthography (variations in spelling, hyphenation)
- phonology (phonetic transcriptions, variations in pronunciation, syllable structure, primary stress)
- morphology (derivational and compositional structure, inflectional paradigms)
- syntax (word class, word class-specific subcategorizations, argument structures)
- word frequency (summed word and lemma counts, based on recent and representative text corpora)
The databases were not tailored to fit any particular database management program. They are presented in ASCII files in a UNIX directory tree that can be queried with tools such as AWK or ICON. Unique identity numbers allow the linking of information from different files. Some information must be computed online; where necessary, AWK functions are provided to recover this information. README files specify the details of their use.
A detailed User Guide describing the lexical information available is included in the documentation accompanying this release. All sections of this guide are POSTSCRIPT files except for some additional ASCII notes on the German lexicon.
Data
This release contains an enhanced, expanded version of the German lexical database (2.5). Approximately 1,000 new lemmas were added for a total of 51,728; their inflected forms number 365,530. Also included are revised morphological parses, verb argument structures, inflectional paradigm codes and a corpus type lexicon. A complete PostScript version of the Germanic Linguistic Guide is included in the documentation accompanying this release.
Phonetic syllable frequencies were added for the English and Dutch databases along with frequency information alongside every lexical feature. No other changes were made to these lexicons.
Complete AWK-scripts are provided to compute representations not found in the ASCII lexical data files corresponding to the features described in CELEX User Guide.
Updates
Petra Stiener has developed a number of scripts to modify and update CELEX2 to a modern format. They are available on her github page.
