LLR Collocation Identifier
--------------------------
Key: MAHOUT-242
URL: https://issues.apache.org/jira/browse/MAHOUT-242
Project: Mahout
Issue Type: New Feature
Affects Versions: 0.3
Reporter: Drew Farris
Priority: Minor
Attachments: mahout-colloc.tar.gz
Identifies interesting Collocations in text using ngrams scored via the
LogLikelihoodRatio calculation.
As discussed in:

Current form is a tar of a maven project that depends on mahout. Build as usual
with 'mvn clean install', can be executed using:
{noformat}
mvn -e exec:java -Dexec.mainClass="org.apache.mahout.colloc.CollocDriver"
-Dexec.args="--input src/test/resources/article --colloc target/colloc --output
target/output -w"
{noformat}
Output will be placed in target/output and can be viewed nicely using:
{noformat}
sort -rn -k1 target/output/part-00000
{noformat}
Includes rudimentary unit tests. Please review and comment. Needs more work to
get this into patch state and integrate with Robin's document vectorizer work
in MAHOUT-237
Some basic TODO/FIXME's include:
* use mahout math's ObjectInt map implementation when available
* make the analyzer configurable
* better input validation + negative unit tests.
* more flexible ways to generate units of analysis (n-1)grams.
