Cannot run the constituency-to-dependency program

[allanj]

1. I directly install on maven.
2. Then I directly run C2DConvert.main(args);
3. where the args are exactly same as your example.

Error:

I check the following class file as well, seems like the maven package doesn't have these files included?

public interface PathEnglishMPAnalyzer
{
    String ROOT = "edu/emory/clir/clearnlp/dictionary/morphology/english/";

    String INFLECTION_SUFFIX = ROOT + "inflection_suffix.xml";
    String DERIVATION_SUFFIX = ROOT + "derivation_suffix.xml";
    String ABBREVIATOIN_RULE = ROOT + "abbreviation.rule";
    String CARDINAL_BASE     = ROOT + "cardinal.base";
    String ORDINAL_BASE      = ROOT + "ordinal.base";

    String VERB          = "verb";
    String NOUN          = "noun";
    String ADJECTIVE     = "adjective";
    String ADVERB        = "adverb";
    String EXT_BASE      = ".base";
    String EXT_EXCEPTION = ".exc";
}

OK, after many trials.

I found out that I can add one more dependency to pom.xml to fix that.

<dependency>
        <groupId>edu.emory.clir</groupId>
        <artifactId>clearnlp-dictionary</artifactId>
        <version>3.2</version>
</dependency>

BTW, it will be good that you can add this to the constituency-to-dependency README. Otherwise, I guess others will have the same problem while using this.

The clearnlp project has been moved to a new project called NLP4J:

https://github.com/emorynlp/nlp4j/

Thanks.

Seems this one does not contain the conversion from constituency to dependency tool

I mean the new project does not contain the constituency-to-dependency conversion tool

[jdchoi77]

Sorry, I'm making a pretty big change in the dependency conversion package at the moment; I'll be pushing this by the end Sep so the new project will have it as well.

[allanj]

Great. Thanks for the information.
