The development of a manual corpus is labor intensive. However, some statistical tech-
niques have been developed to create corpora. A number of corpora are available. One of
the first ones was the Brown Corpus ( http://clu.uni.no/icame/manuals/BROWN/
INDEX.HTM ) . Newer ones include the British National Corpus ( ht-
tp://www.natcorp.ox.ac.uk/corpus/index.xml ) , with over 100 million words, and the
American National Corpus ( http://www.anc.org/ ) . A list of corpora can be found at ht-
tp://en.wikipedia.org/wiki/List_of_text_corpora .
