combine_terms

Aggregate terms in a document-term matrix to according to groupings specified
by a dictionary.

An integrated solution to perform
a series of text mining tasks such as importing and cleaning a corpus, and
analyses like terms and documents counts, lexical summary, terms
co-occurrences and documents similarity measures, graphs of terms,
correspondence analysis and hierarchical clustering. Corpora can be imported
from spreadsheet-like files, directories of raw text files,
as well as from 'Dow Jones Factiva', 'LexisNexis', 'Europresse' and 'Alceste' files.
