A small function to show how to use the stanford-pos-tagger in MATLAB.

Requirements

It requires the following files:

1. english-left3words-distsim.tagger in the current path while running it. It can be found in $STANFORD_POS_TAGGER_PATH/models/
2. stanford-postagger.jar should be added to the classpath. Matlab command to do it: javaaddpath('$STANFORD_POS_TAGGER_PATH/stanford-postagger.jar')

Usage

To run it simply drop it in the current working directory and run:

PosTaggerM(sample_sentence)

Sample input:

This is a very small sample sentence for test purpose - Chomsky.

Sample output:

[This/DT, is/VBZ, a/DT, very/RB, small/JJ, sample/NN, sentence/NN, for/IN, test/NN, purpose/NN, -/:, Chomsky/NNP, ./.]

The result is an ArrayList of TaggedWords.

Note on performance:: See discussion on this issue.

File path for english-left3words-distsim.tagger in Windows:: See discussion on and resolution of this issue.

Compatibility

Verified to work on:

• 3.3.1 and 3.4.1 of the tagger
• Matlab version 2010a, 8.3.0.532 (R2014a), R2016a and R2017a.
• JRE version: 1.7 (JRE 7) and 1.8 (JRE 8).

Also, see this issue for more details.

Acknowledgements

This was initially hosted on my homepage. Douglas found the code and improved it to work with the latest version of the tagger.

@johnnykast helped debug some compatibility issues.

@Sardar-Usama did a detailed analysis of compatibility.
