    • This invention concerns a method and system for monitoring an automated dialog system for the automatic recognition of language understanding errors based on a user's input communications in a task classification system. The method may include determining whether the user's input communication can be understood in order to make a task classification decision. If the user's input communication cannot be understood and a task classification decision cannot be made, a probability of understanding the user's input communication may be determined. If the probability exceeds a first threshold, further dialog may be conducted with the user. Otherwise, the user may be directed to a human for assistance. In another possible embodiment, the method operates as above except that if the probability exceeds a second threshold, the second threshold being higher than the first, then further dialog may be conducted with the user using the current dialog strategy. However, if the probability falls between a first threshold and a second threshold, the dialog strategy may be adapted in order to improve the chances of conducting a successful dialog with the user. This process may be cumulative. In particular, the first dialog exchange may be stored in a database. Then, a second dialog exchange is conducted with the user. As a result, a second determination is made as to whether the user's input communication can be understood can be conducted based on the stored first exchange and the current second exchanges. This cumulative process may continue using a third and fourth exchange, if necessary.
    • 本发明涉及一种用于监视基于用户在任务分类系统中的输入通信的语言理解错误的自动识别的自动对话系统的方法和系统。 该方法可以包括确定是否可以理解用户的输入通信以便进行任务分类决定。 如果不能理解用户的输入通信,并且不能进行任务分类决定,则可以确定理解用户的输入通信的概率。 如果概率超过第一阈值,则可以与用户进行进一步的对话。 否则,用户可能被指示给人以寻求帮助。 在另一个可能的实施例中,除了如果概率超过第二阈值,则该方法高于第一阈值,则可以使用当前对话策略与用户进行进一步的对话。 然而,如果概率落在第一阈值和第二阈值之间,则可以调整对话策略以便提高与用户进行成功对话的机会。 这个过程可能是累积的。 特别地,第一对话交换可以存储在数据库中。 然后,与用户进行第二次对话交换。 结果,可以基于所存储的第一交换和当前的第二交换进行关于用户的输入通信是否可以被理解的第二确定。 如有必要,此累积过程可能会继续使用第三次和第四次交换。

    • This invention concerns a method and system for monitoring an automated dialog system for the automatic recognition of language understanding errors based on a user's input communications. The method illustratively determines whether a probability of understanding the user's input communication exceeds a first threshold. If the first threshold is exceeded, further dialog is conducted with the user. Otherwise, the user may be directed to a human for assistance. The method also illustratively determines whether the probability also exceeds a second threshold, the second threshold being higher than the first. If so, then further dialog is conducted with the user using the current dialog strategy. However, if the probability falls between a first threshold and a second threshold, the dialog strategy may be adapted in order to improve the chances of conducting a successful dialog with the user.
