In the provided Salience Demo app, you can run a piece of text and use the “View Chunk Tagged Text” to see the parts of speech Salience has assigned.
You can force parts of speech on certain words via a file called gluepatterns.dat.
<(='Best')> (='Buy')=>NNP
(='Best') <(='Buy')>=>NNP
This tells Salience to “glue” all instances of Best Buy together and tag both words as NNP, which is a proper noun.
