| Summary : N-Gram-Based Text Categorization Library
|
Description :
Libtextcat is a library with functions that implement the classification
technique described in Cavnar & Trenkle, \"N-Gram-Based Text
Categorization\". It was primarily developed for language guessing, a task on
which it is known to perform with near-perfect accuracy.
The central idea of the Cavnar & Trenkle technique is to calculate a
\"fingerprint\" of a document with an unknown category, and compare this with
the fingerprints of a number of documents of which the categories are
known. The categories of the closest matches are output as the
classification. A fingerprint is a list of the most frequent n-grams occurring
in a document, ordered by frequency. Fingerprints are compared with a simple
out-of-place metric.
Considerable effort went into making this implementation fast and
efficient. The language guesser processes over 100 documents/second on a
simple PC, which makes it practical for many uses. It was developed for use in
our webcrawler and search engine software, in which it it handles millions of
documents a day.
