...

• ApproximatedForwardSearch: if enabled the system runs a simplified search. faster but less accurate.
• CaseSensitive: if true, variables are case sensitive, otherwise everything is lowercased internally.
• DmClass: the DM class to be used (e.g. RewardDM)
• DmVhGenerating: if true the DM generates the vrGenerate message.
• DmVhListening: if true listens to vrNLU.
• ForcedIgnoreEventName: name of the event generated when the dm ignores a user event.
• InitialPolicyFileName: the name of the policy file.
• LoginEventName: the name of the event generated at login.
• LoopEventName:the name of the event generated if the DM recognizes that it's stuck in a loop.
• MaxIterations: maximum number of iterations for a single event. it's a safeguard for bugs in the policy and event handling.
• MaxSearchLevels: used to stop the search, defines the maximum depth of the visited search space.
• PreferUserInitiatedActions: if true, it prefers a user initiated action from the possibilities found by the search.
• SkipUnhandledWhileSystemSpeaking: if true, doesn't generate the unhandled event while the system is speaking.
• SpecialVariablesFileName: the name of the file used to dump the list of special variables at startup.
• SpokenFractionForSaid: percentage of a line that needs to be said (before interruption) for a line to be considered said.
• StaticURLs
• SystemEventsHaveDuration: if true, the system will track the NLG to wait for a line to be finished before moving on.
• TimerEvent: the name of the timer event.
• TimerInterval: the length of time in seconds between timer events. if negative, timer events are disabled.
• TrivialSystemSpeechActs
• UnhandledEventName: the name of the event generated when the system doesn't have an executable operator that can handle the current user event.
• UserAlwaysInterrupts: if true, the user always interrupt the system.
• ValueTrackers
• VisualizerClass
• VisualizerConfig
• : trackers used to update specific variables with high precision. See src/DMConfigs.xml for examples.
• VisualizerClass: used to visualize the DM state, mostly deprecated.
• VisualizerConfig: see VisualizerClass
• WaitForUserReplyTimeout: number of seconds for which we allow a user to take to reply.WaitForUserReplyTimeout

NLG configuration

• AllowEmptyNLGOutput: if true the NLG can return empty text, otherwise it'll generate an error if empty text is returned.
• AlwaysPreferForms: global flag used to prefer forms (multiple choice) for a given speech act if forms are defined for it/
• DefaultDuration: default duration of a speech act. Usually VH messages are used to compute this, or the audio file, or the length of the text. If all custom methods fail, then this default is used.
• DisplayFormAnswerInNlg: in case multiple choice is used, the nlg will return the full selected answer.
• IsAsciiNLG: if true, it filters non ASCII characters from the nlg text.
• IsNormalizeBlanksNLG
• IsStrictNLG
• LfNlgLexiconFile
• NlgClass
• NlgVhGenerating
• NlgVhListening
• Nvbs
• Picker
• SystemForms
• SystemResources
• : if true, normalizes blanks in the nlg text (removes duplicates, clean end of line).
• IsStrictNLG: if true, it returns errors for each speech act used in the DM policy from which the NLG cannot return text.
• LfNlgLexiconFile: not used
• NlgClass: the NLG class used to generate text from speech acts.
• NlgVhGenerating: not used, typically specific NLGs generate vh messages.
• NlgVhListening: is true, listens to vrGenerate.
• Nvbs: file that contains the nvb info.
• Picker: class that specify how to pick one text realization from multiple possibilities for a given speech act.
• SystemForms: name of the file that contains the definition of the multiple choice system lines.
• SystemResources: name of the file that contains resources (e.g. links)
• SystemUtterances: name of the file that contains the system lines (mapping between speech acts and surface form).SystemUtterances
