Tadpole, which stands for Tagger, Dependency Parser, and Other Linguistic Engines, is an integration of memory-based language processing modules developed for Dutch. All modules are based on Timbl version 6.1.

Tadpole's current version number is 0.2, and is in beta state. It does not offer dependency parsing yet; the current version will tokenize, tag, lemmatize, and morphologically segment word tokens in incoming Dutch text files. We expect to be updating Tadpole frequently during 2008.

Tadpole expects simple, raw, ASCII (iso latin-1) texts as input, and will produce tab-delimited four-column output that looks as follows (wrapped to fit):

De      LID(bep,stan,rest)      de      [de]
oprichter       N(soort,ev,basis,zijd,stan)
     oprichter       [op][richt][er]

Please consult the README file in the package for installation instructions. This file will remind you to check the following:

• Tadpole relies on Timbl version 6.0 and Mbt version 3.0; Mbt in turn relies on Timbl 6.0 to be installed. Tadpole will NOT work with previous versions of Timbl and Mbt.
• The tarball will unpack ('tar zxvf tadpole-0.2-beta.tar.gz') in a directory called 'tadpole-0.2-beta'.
• When in the tadpole-0.2-beta directory, issue a './configure' command (for possible command line options, see the README file), followed by 'make'.
