Stopwords for Greek and Latin

Status quaestionis
stop word, n. A very common word that is generally uninteresting to search for (a XTF Definition).

If you are not a linguist with a special interest in words like Latin "cum" or Greek "kai", or if you have a large collection of Greek or Latin texts and want to make searches in these collection more efficient, or if you have to prepare an index to such a collection (probably based on automatic concordances), it is useful to have a list of stop words handy.

Of course, such "uninteresting" words will not be excluded from your search results (thanks to the so called "bigramming", q. v. on the XTF Definition link). Also, you can have both, providing to users of your collections searches with filtered stop words and without such filter (as it is done in Perseus under PhiloLogic).

However, at the moment there are no stop word lists freely available for Greek or Latin; it seems that people compile them when they need them (and if they have the time), thereby doing the same all over again, instead of possibly improving on what others already did.

The stop words (apparently) used by Perseus are (see reading/src/perseus/search/greek/GreekAnalyzer.java and reading/src/perseus/search/latin/LatinAnalyzer.java in the source):

N.B. however that depending on your corpus, word frequencies could be distributed differently. One approach may be to run a Lucene index on your corpus with no stop words first, then use Luke to get the top n terms for your corpus and filter that result depending on what kind of stop word behavior you want.
