摘要
An orphan detector. The orphan detector processes out-of-domain utterances from a targeted language understanding dialog system to determine whether the out-of-domain utterance expresses a specific intent to have the targeted language understanding dialog system to take a certain action where fallback processing, such as performing a generic web search, is unlikely to be satisfied by web searches. Such utterances are referred to as orphans because they are not appropriately handled by any of the task domains or fallback processing. The orphan detector distinguishes orphans from web search queries and other out-of-domain utterances by focusing primarily on the structure of the utterance rather than the content. Orphans detected by the orphan detector may be used both online and offline to improve user experiences with targeted language understanding dialog systems. The orphan detector may also be used to mine structurally similar queries or sentences from the web search engine query logs.
