Linguistic Toolbox (LIT) is a concordancer that allows the user creating his/her own pos-annotated corpora and performing all types of searches adopted in corpus linguistics. LIT has a built-in part-of speech tagger that we created ourselves - STAR-tagger (START).

LIT has an integrated WordNet module and the users can find  semantically related  words and get information about patterns of their distribution across texts. 

Requirements:

Windows 2000/XP/Vista/7
1500 MHz processor
Mono runtime
1 GB of free disc space
