  • AcceptanceThreshold: if configured (i.e. not null or negative) the NLU will return its 1-best result only if the confidence score associated with it is above this threshold.
  • ChartNluInSingleMode: used by the class edu.usc.ict.nl.nlu.chart.MXChartClassifierNLU to disable the multiple speech acts extraction described in the paper: http://www.aclweb.org/anthology/P11-2017
  • ChartNluMaxLength: used by the class edu.usc.ict.nl.nlu.chart.MXChartClassifierNLU to automatically disable extracting multiple speech acts for longer utterances, see http://www.aclweb.org/anthology/P11-2017
  • EmptyTextEventName: if the user enters no text, then this event is returned by the NLU.
  • ForcedNLUContentRoot: this is the path to the NLU models in case you don't want to use the default location in a character folder.
  • FstInputSymbols: configuration used by the attempts to use Finite state transducers to do NLU for SPS. Read the code for more info.

  • : see FstInputSymbols
  • HierNluReturnsNonLeaves: boolean, default true. used in hierarchical NLU models, if true the model will return also non leaves (i.e. result from a NLU model that has children NLU models) when the result has a higher probability than the results of its children
  • HierarchicalNluSeparator: separator used in the labels to recognize hierarchical structure. For example, "." is the hier separator for java packages.
  • InternalNluClass4Chart: internal NLU class used by the chart classifier (multiple speech acts in a single line of text)
  • InternalNluClass4Hier: internal NLU class used in hierarchical NLU models.
  • InternalNluListForMultiNlu: list of NLU beans to run simultaneously in the multi NLU setup (e.g. SPS).
  • LowConfidenceEvent: event sent out if the 1-best NLU result is below the AcceptanceThreshold.
  • MaximumNumberOfLabels: maximum number of labels to be found in the training set. Used to generate an error or warning if it's known that the particular classifier used has this limitation (on the number of labels).
  • MergerForMultiNlu: bean to use to reach a single output from a multi NLU setup. For example, if classifier 1 returns result r1 then run classifier 2 and return result r2 as the global result, otherwise return r1.
  • NluClass: the basic NLU class used (could be a hierarchical or multi or chart or simple classifier). check out src/NLUConfigs.xml for some examples. Check out the resources/characters/*/NLUConfig.xml for other examples.
  • NluDir: the name of the directory under which the nlu stores its model: ContentRoot/characterName/NluDir
  • NluExeEnv: setup needed only when running specific external nlu exe that requires custom environment variables (check the source code, never used).
  • NluExeRoot: see NluExeEnv.NluExeRoot
