Principle of maximum entropyAugust 21, 2008
Something to investigate is the principle of maximum entropy which the CodePlex project relies on. Penn Treebank ProjectAugust 21, 2008
Here's an interesting project, called the Penn Treebank Project. The Penn Treebank Project annotates naturally-occuring text for linguistic structure. Most notably, we produce skeletal parses showing rough syntactic and semantic information -- a bank of linguistic trees. We also annotate text with part-of-speech tags, and for the Switchboard corpus of telephone conversations, dysfluency annotation. We are located in the LINC Laboratory of the Computer and Information Science Department at the University of Pennsylvania.Also: CC Coordinating conjunction RP Particle
CD Cardinal number SYM Symbol
DT Determiner TO to
EX Existential there UH Interjection
FW Foreign word VB Verb, base form
IN Preposition/subordinate VBD Verb, past tense
