public class StanfordLexicalizedParser extends adams.flow.transformer.AbstractTransformer
Parses a string (= sentence) or string array (= tokenized sentence) using the Stanford LexicalizedParser.
Input/output:
- accepts:
java.lang.String
java.lang.String[]
- generates:
edu.stanford.nlp.trees.Tree
-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel) The logging level for outputting errors and debugging output. default: WARNING
-name <java.lang.String> (property: name) The name of the actor. default: StanfordLexicalizedParser
-annotation <adams.core.base.BaseText> (property: annotations) The annotations to attach to this actor. default:
-skip <boolean> (property: skip) If set to true, transformation is skipped and the input token is just forwarded as it is. default: false
-stop-flow-on-error <boolean> (property: stopFlowOnError) If set to true, the flow gets stopped in case this actor encounters an error; useful for critical actors. default: false
-model <adams.core.io.PlaceholderFile> (property: model) The model file to load and use. default: ${CWD}
-additional-option <adams.core.base.BaseString> [-additional-option ...] (property: additionalOptions) The additional options for the parser. default:
