Re: Custom Features Generator example
Joern it works perfectly! I am extending the CustomFeatureGenerator, it is called and init() method too. Last thing...I need to use some resources like custom dictionaries and specific finder with many regexes, how can i store those resouces into the model? I am configuring the generators via xml, i read that it is saved on the model (.bin file), but, what about those custom resources? are they saved inside the model too ? 2016-10-25 14:04 GMT+02:00 Joern Kottmann : > You can pass in custom parameters to configure your feature generator > (depends on what you need) via attributes on the custom element in the > descriptor. > > This is optional if you don't have any parameters, you don't need to pass > anything at all. > > Jörn > > > On Tue, Oct 25, 2016 at 2:00 PM, Damiano Porta > wrote: > > > Oh thanks! i try. > > If I extend the CustomFeatureGenerator what parameters should i pass? > > > > Il 25/Ott/2016 13:39, "Joern Kottmann" ha scritto: > > > > > You need to use a constructor which is public and has no arguments. > > > > > > The parameters can be passed in only if you extend > > CustomFeatureGenerator. > > > That one has an init method which gives you the attributes defined in > the > > > xml descriptor. > > > > > > HTH, > > > Jörn > > > > > > On Tue, Oct 25, 2016 at 12:43 PM, Damiano Porta < > damianopo...@gmail.com> > > > wrote: > > > > > > > Joern, > > > > However i also tried with: > > > > > > > > public SpanFeatureGenerator(Map properties, > > > > FeatureGeneratorResourceProvider resourceProvider) throws > > > > InvalidFormatException { > > > > > > > > } > > > > > > > > but i get the same exception. > > > > Damiano > > > > > > > > 2016-10-25 12:30 GMT+02:00 Damiano Porta : > > > > > > > > > This at the moment: > > > > > > > > > > public SpanFeatureGenerator(String prefix, Object finder, int > > > > > prevWindowSize, int nextWindowSize) { > > > > > > > > > > System.out.println(prefix); > > > > > System.out.println((String)finder); > > > > > System.out.println(prevWindowSize); > > > > > System.out.println(nextWindowSize); > > > > > System.exit(1); > > > > > > > > > > } > > > > > > > > > > It is obviously a test to understand if my generator is called. > > > > > > > > > > > > > > > 2016-10-25 12:23 GMT+02:00 Joern Kottmann : > > > > > > > > > >> What is the constructor of the > > > > >> com.damiano.parser.generator.SpanFeatureGenerator > > > > >> class? > > > > >> > > > > >> Jörn > > > > >> > > > > >> On Tue, Oct 25, 2016 at 11:51 AM, Damiano Porta < > > > damianopo...@gmail.com > > > > > > > > > >> wrote: > > > > >> > > > > >> > Hello, > > > > >> > I have created a custom generator implementing the > > > > >> AdaptiveFeatureGenerator > > > > >> > interface. > > > > >> > > > > > >> > I am getting this error: > > > > >> > > > > > >> > Exception in thread "main" > > > > >> > opennlp.tools.util.ext.ExtensionNotLoadedException: > > > > >> > java.lang.InstantiationException: > > > > >> > com.damiano.parser.generator.SpanFeatureGenerator > > > > >> > at > > > > >> > opennlp.tools.util.ext.ExtensionLoader.instantiateExtension( > > > > >> > ExtensionLoader.java:72) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory$ > > > > >> > CustomFeatureGeneratorFactory.create(GeneratorFactory.java:582) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > > > >> > GeneratorFactory.java:661) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory$ > > > > >> > AggregatedFeatureGeneratorFactory.create(GeneratorFactory. > > java:129) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > > > >> > GeneratorFactory.java:661) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory$ > > > > >> > CachedFeatureGeneratorFactory.create(GeneratorFactory.java:171) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > > > >> > GeneratorFactory.java:661) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory$ > > > > >> > AggregatedFeatureGeneratorFactory.create(GeneratorFactory. > > java:129) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > > > >> > GeneratorFactory.java:661) > > > > >> > at > > > > >> > opennlp.tools.util.featuregen.GeneratorFactory.create( > > > > >> > GeneratorFactory.java:711) > > > > >> > at > > > > >> > opennlp.tools.namefind.TokenNameFinderFactory. > > > > createFeatureGenerators( > > > > >> > TokenNameFinderFactory.java:153) > > > > >> > at > > > > >> > opennlp.tools.namefind.TokenNameFinderFactory. > > > createContextGenerator( > > > > >> > TokenNameFinderFactory.java:118) > > > > >> > at opennlp.tools.namefind.NameFinderME.train( > > NameFinderME.java:333) > > > > >> > at com.damiano.parser.trainer.NER.compileNER(NER.java:161) > > > > >> > at com.damiano.parser.trainer.NER.main(NER.java:136) > > >
Re: Custom Features Generator example
You can pass in custom parameters to configure your feature generator (depends on what you need) via attributes on the custom element in the descriptor. This is optional if you don't have any parameters, you don't need to pass anything at all.

Re: Custom Features Generator example
You need to use a constructor which is public and has no arguments. The parameters can be passed in only if you extend CustomFeatureGenerator. That one has an init method which gives you the attributes defined in the xml descriptor.

Re: Custom Features Generator example
Joern, However i also tried with: public SpanFeatureGenerator(Map properties, FeatureGeneratorResourceProvider resourceProvider) throws InvalidFormatException { } but i get the same exception.

Re: Custom Features Generator example
This at the moment: public SpanFeatureGenerator(String prefix, Object finder, int prevWindowSize, int nextWindowSize) { System.out.println(prefix); System.out.println((String)finder); System.out.println(prevWindowSize); System.out.println(nextWindowSize); System.exit(1); } It is obviously a test to understand if my generator is called. 2016-10-25 12:23 GMT+02:00 Joern Kottmann : > What is the constructor of the > com.damiano.parser.generator.SpanFeatureGenerator > class? > > Jörn > > On Tue, Oct 25, 2016 at 11:51 AM, Damiano Porta > wrote: > > > Hello, > > I have created a custom generator implementing the > AdaptiveFeatureGenerator > > interface. > > > > I am getting this error: > > > > Exception in thread "main" > > opennlp.tools.util.ext.ExtensionNotLoadedException: > > java.lang.InstantiationException: > > com.damiano.parser.generator.SpanFeatureGenerator > > at > > opennlp.tools.util.ext.ExtensionLoader.instantiateExtension( > > ExtensionLoader.java:72) > > at > > opennlp.tools.util.featuregen.GeneratorFactory$ > > CustomFeatureGeneratorFactory.create(GeneratorFactory.java:582) > > at > > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > GeneratorFactory.java:661) > > at > > opennlp.tools.util.featuregen.GeneratorFactory$ > > AggregatedFeatureGeneratorFactory.create(GeneratorFactory.java:129) > > at > > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > GeneratorFactory.java:661) > > at > > opennlp.tools.util.featuregen.GeneratorFactory$ > > CachedFeatureGeneratorFactory.create(GeneratorFactory.java:171) > > at > > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > GeneratorFactory.java:661) > > at > > opennlp.tools.util.featuregen.GeneratorFactory$ > > AggregatedFeatureGeneratorFactory.create(GeneratorFactory.java:129) > > at > > opennlp.tools.util.featuregen.GeneratorFactory.createGenerator( > > GeneratorFactory.java:661) > > at > > opennlp.tools.util.featuregen.GeneratorFactory.create( > > GeneratorFactory.java:711) > > at > > opennlp.tools.namefind.TokenNameFinderFactory.createFeatureGenerators( > > TokenNameFinderFactory.java:153) > > at > > opennlp.tools.namefind.TokenNameFinderFactory.createContextGenerator( > > TokenNameFinderFactory.java:118) > > at opennlp.tools.namefind.NameFinderME.train(NameFinderME.java:333) > > at com.damiano.parser.trainer.NER.compileNER(NER.java:161) > > at com.damiano.parser.trainer.NER.main(NER.java:136) > > > > Caused by: java.lang.InstantiationException: > > com.damiano.parser.generator.SpanFeatureGenerator > > at java.lang.Class.newInstance(Class.java:427) > > at > > opennlp.tools.util.ext.ExtensionLoader.instantiateExtension( > > ExtensionLoader.java:70) > > ... 14 more > > > > Caused by: java.lang.NoSuchMethodException: > > com.damiano.parser.generator.SpanFeatureGenerator.() > > at java.lang.Class.getConstructor0(Class.java:3082) > > at java.lang.Class.newInstance(Class.java:412) > > ... 15 more > > > > the xml is: > > > > > > > > > > > > > > > > > > > > > > > > > > > > > >> prefix="name" finder="blablabla" prevWindowSize="3" nextWindowSize="3"/> > > > > > > > > > > What can i do? > > Thank you! > > > > Damiano > > >
Re: Custom Features Generator example
What is the constructor of the com.damiano.parser.generator.SpanFeatureGenerator class?
