Description
Machinery for mining CWB corpora
Details
The package provides functions for basic text statistics for corpora
that are managed by the Corpus Workbench (CWB). A core feature is to generate
subcorpora/partitions based on metadata. The package is also meant to serve
as an interface between the CWB and R-packages implementing more
sophisticated statistical procedures (e.g. lsa, lda, topicmodels) or
providing further functionality for text mining (e.g. tm).
Any analysis using this package will usually start with setting up a
subcorpus/partition (with partition). A set of partitions can be
generated with partitionBundle. Once a partition or a set of partitions
has been set up, core functions are context and
compare. Based on a partition bundle, a
term-document matrix (class 'TermDocumentMatrix' from the tm package) can be
generated (with as.TermDocumentMatrix). This opens the door to the wealth of
statistical methods implemented in R.
