A system, method, and computer-program product is provided for answering a natural language query in an automated manner. The answer is drawn from a body of textual information. Concepts in the body of textual information in a domain are expressed as a set of semantic headers. The semantic headers represent formalizations of select concepts in the information domain, and are created on the basis of expected queries. Moreover, queries are reduced to a canonical form. The answering process comprises the step of matching the formalized query, or translation formula, to one or more semantic headers. The pieces of text which correspond to those semantic headers are returned to the user as answers. The generality of a translation formula can be controlled. Steps can be taken to make the translation formula more general or less general. A user can clarify a translation formula if necessary. If the user provides a term that is not immediately recognized, then the user will be presented with a number of options. Each option represents one way in which the term in question can be clarified. The invention can then incorporate the new term into the translation formula and attempt to match one or more appropriate semantic headers. In addition, the domain can be expanded by parties other than the provider of the domain.

The disclosure relates to methods, systems and other embodiments directed to determining an information domain match for a natural language (NL) input (e.g., a spoken utterance), and confirming whether the NL input is correctly matched to the information domain. For example, after receiving an NL input, a first information domain to which the NL input belongs and a feature value set may be determined based on a semantic pattern matching technique. Further, a second information domain to which the NL input belongs, and a corresponding confidence score related to the second information domain may be determined. The second information domain may be determined based on a first statistical classification technique. Based on the determined feature value set and the confidence score related to the second information domain, it may be confirmed whether the NL input correctly belongs to the first information domain, e.g., based on a second statistical classification technique.

Mechanisms have been developed for synchronizing information, e.g., password or other access credential information, amongst replicated directory spaces or repositories.

Mechanisms have been developed for synchronizing information, e.g., password or other access credential information, amongst directory spaces or repositories, that employ dissimilar protective transformations, e.g., hashes, encryption, etc. In some exemplary realizations, directory spaces are embodied as directory servers, services or similar components of computer operating systems. In some exemplary realizations, dissimilar protective transformations include differing hashes (or encryption) techniques or facilities employed by products available from Sun Microsystems, Inc., on the one hand, and Microsoft Corporation on another. However, the inventive techniques are not limited thereto. The mechanism includes detecting changes to information encoded in a first information store and invalidating a corresponding entry of a second information store. The invalidating triggers information synchronization upon a subsequent attempt to authenticate against this entry in the second store. The detection may be administered without reversing a protective transform of the entries.
