    <p>Here's some (old) sample code I threw together, with modernized code to follow:</p> <pre><code>package opennlp; import opennlp.tools.cmdline.PerformanceMonitor; import opennlp.tools.cmdline.postag.POSModelLoader; import opennlp.tools.postag.POSModel; import opennlp.tools.postag.POSSample; import opennlp.tools.postag.POSTaggerME; import opennlp.tools.tokenize.WhitespaceTokenizer; import opennlp.tools.util.ObjectStream; import opennlp.tools.util.PlainTextByLineStream; import java.io.File; import java.io.IOException; import java.io.StringReader; public class OpenNlpTest { public static void main(String[] args) throws IOException { POSModel model = new POSModelLoader().load(new File("en-pos-maxent.bin")); PerformanceMonitor perfMon = new PerformanceMonitor(System.err, "sent"); POSTaggerME tagger = new POSTaggerME(model); String input = "Can anyone help me dig through OpenNLP's horrible documentation?"; ObjectStream&lt;String&gt; lineStream = new PlainTextByLineStream(new StringReader(input)); perfMon.start(); String line; while ((line = lineStream.read()) != null) { String whitespaceTokenizerLine[] = WhitespaceTokenizer.INSTANCE.tokenize(line); String[] tags = tagger.tag(whitespaceTokenizerLine); POSSample sample = new POSSample(whitespaceTokenizerLine, tags); System.out.println(sample.toString()); perfMon.incrementCounter(); } perfMon.stopAndPrintFinalResult(); } } </code></pre> <p>The output is:</p> <pre><code>Loading POS Tagger model ... done (2.045s) Can_MD anyone_NN help_VB me_PRP dig_VB through_IN OpenNLP's_NNP horrible_JJ documentation?_NN Average: 76.9 sent/s Total: 1 sent Runtime: 0.013s </code></pre> <p>This is basically working from the POSTaggerTool class included as part of OpenNLP. The <code>sample.getTags()</code> is a <code>String</code> array that has the tag types themselves.</p> <p>This requires direct file access to the training data, which is really, really lame.</p> <p>An updated codebase for this is a little different (and probably more useful.)</p> <p>First, a Maven POM:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;groupId&gt;org.javachannel&lt;/groupId&gt; &lt;artifactId&gt;opennlp-example&lt;/artifactId&gt; &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;org.apache.opennlp&lt;/groupId&gt; &lt;artifactId&gt;opennlp-tools&lt;/artifactId&gt; &lt;version&gt;1.6.0&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.testng&lt;/groupId&gt; &lt;artifactId&gt;testng&lt;/artifactId&gt; &lt;version&gt;[6.8.21,)&lt;/version&gt; &lt;scope&gt;test&lt;/scope&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt; &lt;version&gt;3.1&lt;/version&gt; &lt;configuration&gt; &lt;source&gt;1.8&lt;/source&gt; &lt;target&gt;1.8&lt;/target&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; &lt;/project&gt; </code></pre> <p>And here's the code, written as a test, therefore located in <code>./src/test/java/org/javachannel/opennlp/example</code>:</p> <pre><code>package org.javachannel.opennlp.example; import opennlp.tools.cmdline.PerformanceMonitor; import opennlp.tools.postag.POSModel; import opennlp.tools.postag.POSSample; import opennlp.tools.postag.POSTaggerME; import opennlp.tools.tokenize.WhitespaceTokenizer; import org.testng.annotations.DataProvider; import org.testng.annotations.Test; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.net.URL; import java.nio.channels.Channels; import java.nio.channels.ReadableByteChannel; import java.util.stream.Stream; public class POSTest { private void download(String url, File destination) throws IOException { URL website = new URL(url); ReadableByteChannel rbc = Channels.newChannel(website.openStream()); FileOutputStream fos = new FileOutputStream(destination); fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE); } @DataProvider Object[][] getCorpusData() { return new Object[][][]{{{ "Can anyone help me dig through OpenNLP's horrible documentation?" }}}; } @Test(dataProvider = "getCorpusData") public void showPOS(Object[] input) throws IOException { File modelFile = new File("en-pos-maxent.bin"); if (!modelFile.exists()) { System.out.println("Downloading model."); download("http://opennlp.sourceforge.net/models-1.5/en-pos-maxent.bin", modelFile); } POSModel model = new POSModel(modelFile); PerformanceMonitor perfMon = new PerformanceMonitor(System.err, "sent"); POSTaggerME tagger = new POSTaggerME(model); perfMon.start(); Stream.of(input).map(line -&gt; { String whitespaceTokenizerLine[] = WhitespaceTokenizer.INSTANCE.tokenize(line.toString()); String[] tags = tagger.tag(whitespaceTokenizerLine); POSSample sample = new POSSample(whitespaceTokenizerLine, tags); perfMon.incrementCounter(); return sample.toString(); }).forEach(System.out::println); perfMon.stopAndPrintFinalResult(); } } </code></pre> <p>This code doesn't actually <em>test</em> anything - it's a smoke test, if anything - but it should serve as a starting point. Another (potentially) nice thing is that it downloads a model for you if you don't have it downloaded already.</p>

    2. COI have no idea! I'm working on that now, because I just realized - thanks to your question - how useful OpenNLP would be for a task of my own. :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
