UimaFit to UIMA AS PEARs

[chuon...@gmail.com]

I followed the tutorial for the dkpro, which is heavily reliant on UimaFit, and got a working pipeline.  I now want to convert that pipeline into a PEAR so that it can be deployed to a UIMA AS cluster.  I've figured out that I can call the toXML() to get the XML descriptors for the analysis engines.  How do I convert the CollectionReader and the runpipeline part of the code?  The code is below for reference, and is very similar to the example code for UimaFit.  Thanks

CollectionReader reader = createCollectionReader(TextReader.class,
    TextReader.PARAM_PATH, "src/test/resources/text",
    TextReader.PARAM_PATTERNS, new String[] { "[+]*.txt", "[-]broken.txt" },
    TextReader.PARAM_LANGUAGE, "en");

AnalysisEngine tokenizer = createPrimitive(BreakIteratorSegmenter.class);

AnalysisEngine nameFinder = createPrimitive(DictionaryAnnotator.class,
    DictionaryAnnotator.PARAM_PHRASE_FILE, "src/test/resources/dictionaries/names.txt",
    DictionaryAnnotator.PARAM_ANNOTATION_TYPE, Name.class.getName());

AnalysisEngine writer = createPrimitive(CASDumpWriter.class,
    CASDumpWriter.PARAM_OUTPUT_FILE, "target/output.txt");

SimplePipeline.runPipeline(reader, tokenizer, nameFinder, writer);

Hi,

I think you are not subscribed to this list, so I set you CC.

It has been quite a while that I experimented with UIMA-AS. I committed what I have done so far to the DKPro Lab project. You can have a look at the SimpleComponentTest class [1].

In that experiment, I only started a local UIMA-AS instance, I didn't talk to remote services. It may still illustrate how to pass as CAS to UIMA-AS.

The initializeClient() method in [2] may also he helpful.

Maybe we can find a more convenient way to support uimaFIT-based PEARs and UIMA-AS. E.g. it could be imagined to beef up the uimaFIT Maven Plugin that will come with uimaFIT 2.0.0 with some support for generating aggregate descriptors and packaging PEARs.

Cheers,
