At the present time, Grobid NER is a java library.

The NER can be called as follow.

Building with maven

When using maven, you need to include in your pom file the path to the grobid-core and grobid-ner jar files, for instance as follow (replace 0.2.14 by the valid <current version>):

<dependency>
    <groupId>org.grobid.core</groupId>
    <artifactId>grobid</artifactId>
    <version>0.2.14</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/lib/grobid-core-0.2.10.jar</systemPath>
</dependency>

<dependency>
    <groupId>org.grobid.ner</groupId>
    <artifactId>grobid-ner</artifactId>
    <version>0.2.1</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/lib/grobid-ner-0.2.1.jar</systemPath>
</dependency>

API call

When using Grobid NER, you have to initiate a context with the path to the Grobid resources, the following class give an example of usage:

    import org.grobid.core.*;
    import org.grobid.core.data.*;
    import org.grobid.core.factory.*;
    import org.grobid.core.mock.*;
    import org.grobid.core.utilities.*;
    import org.grobid.core.data.Entity;
    import org.grobid.core.data.Sense;
    import org.grobid.core.engines.NERParser;

    ...

try {
        String pGrobidHome = "/Users/lopez/grobid/grobid-home";
        String pGrobidProperties = "/Users/lopez/grobid/grobid-home/config/grobid.properties";

        MockContext.setInitialContext(pGrobidHome, pGrobidProperties);      
        GrobidProperties.getInstance();
        LibraryLoader.load();

        System.out.println(">>>>>>>> GROBID_HOME="+GrobidProperties.get_GROBID_HOME_PATH());

        NERParser nerParser = new NERParser();

        List<Entity> results = nerParser.extractNE(text);

        for(Entity entity: results) {
            System.out.println(entity.toJson());
        }
    } 
    catch (Exception e) {
        // If an exception is generated, print a stack trace
        e.printStackTrace();
    } 
    finally {
        try {
            MockContext.destroyInitialContext();
        } 
        catch (Exception e) {
            e.printStackTrace();
        }
    }

The context paths (pGrobidHome and pGrobidProperties) can be set by a property file, or for a web application by a web.xml file (see for instance grobid-service).
