Usage

This will run on any Unix-like system with Aspell and the Czech Aspell dictionaries installed.

To run all the tests, use ./run_tests.sh. This will create a /tmp/results.txt file which contains verbose output. To summarize the output, run ./summarize_results.pl.

Test Set

From Pavel:

1) We POS-tagged our BMC collection of medical documents in Czech and
extracted "interesting" expressions (noun phrases, consisting of 1-3
words) based on their frequency and pointwise mutual information. So all
the expressions are likely to be used as queries in Khresmoi.

2) We have introduced three types of errors letter errors (insertion,
deletion, swap, replacement, each appearing in 20% of erroneous words),
diacritics strip (50% of erroneous words), concatenation of words (10%
of erroneous words).

Results

Based on the included misspelled Czech term data, Aspell v0.60.6 generates the following results:
