The Muenster lexical database holds lexical data for five languages. For each language, for a certain amount of lexical entries, both linguistic and statistical information is contained. The richness of the lexical information varies from language to language. Ca. 10 000 entries of each languages are connected by a bilingual equivalent-relation. Data in the Muenster (relational) lexical database are stored in tables and accessible through a relational query language (SQL). Conversion of (portions of) the data is possible and carried out by programming languages (C, PROLOG) with embedded SQL statements. I. monolingual data a. English 86 000 wordform:lemma:pos tuples 47 000 different strings serving as entry points for further linguistic information lemma:fullform relation for the English data: verbs: 1:4 nouns: 1:2 adjectives: 1:1 (regular) b. Spanish 45 000 different strings serving as entry points for further linguistic information 6 500 collocations 55 000 word-form:lemma pairs lemma:fullform relation for the Spanish data verbs: regular - about 1:20 irregular - about 1:45 nouns: regular 1:2 - 1:4 adjectives: 1:4 c. French 135 000 word-form:lemma pairs 30 000 lemmas lemma:fullform relation for the French data verbs: 1:20 - 1:30 nouns: 1:2 and 1:4 adjectives: 1:4 d. Italian 70 000 word-form:lemma pairs 12 000 different strings serving as entry points for further linguistic information Italian ans Spanish lemmatization is actually worked on. For these languages the part of speech infoormation for every lexical entry is specified. Besides that, there exist ordered frequency lists derived from the corpora. e. German for 485 000 word-form:lemma pairs there exist detailed grammatical information describing the place(s) of the word-form in the paradigm of the lemma. This information is generated by a morphological generator. GEnerated forms are compared with documented full form extracted from the corpora. for 130 000 strings serving as lexical entries you find the following information: GRAPH: citation form syllable structure SYNCAT MORPH: for VERBS: perfaux separable prefix perfect prefix for NOUNS: GENDER inflection classes stem alternation SYNSEM: for VERBS: SUBCAT II. bilingual data For the following language pairs bilingual dictionaries in both directions are available or worked on. German - English German - Spanish German - French German - Italian German - Standard Modern Greek Each dictionary comprises 10 000 lexical entries. For each entry the equivalents in the target language are given. For more than one target equivalent the readings of the source lemma are distinguished by semantic glosses in the source language. The lexical entries are selected by weighting the absolute frequency of their occurrence based on the corpora.
