A transactional file system wherein multiple file system operations may be performed as transaction. An application specifies that file system-related operations should be handled in a transaction, and is given a file handle associated with a transaction context. For file system requests associated with a transaction context, a file system component manages operations consistent with transactional behavior. The component provides data isolation by providing multiple file versions such that transactional readers do not receive changes until after the transaction commits and the reader reopens the file. The component handles namespace logging operations in a multiple-level log that facilitates logging and recovery. Page data is logged separate from the main log, with signatures establishing whether pages were fully flushed to disk. Namespace isolation via isolation directories allows a transaction to see its operational effects but not effects of other uncommitted transactions. Transactions over a network are facilitated.

Systems and methods for generating prompts for further data from a user in a multi-turn interactive dialog. Embodiments improve searches for the most relevant items available for purchase in an electronic marketplace via a processed sequence of user inputs and machine-generated prompts. Question type prompts, validating statement type prompts, and recommendation type prompts may be selectively generated based on whether a user query has been sufficiently specified, user intent is ambiguous, or a search mission has changed. Detection of a new dominant object denotes search mission change. Contextual associations between prompts and user replies are maintained, but a search mission change results in previous context data being disregarded. Prompts can be directed to unspecified knowledge graph dimensions based on data element association strength values, relative data element positions and depths in the knowledge graph, and generated following a predetermined order of data element knowledge graph dimension types.

Communication connectivity via context association is provided by associating targeted subscriber contact information with a key at a subscriber database. At a data center, the keys are associated with unique characteristics or aliases (contexts) of the subscribers, thereby facilitating context searching. A caller initiates a connection to a subscriber by providing a subscriber's context. The context is located and associated key identified. The key is resolved in the subscriber database, and the call routed. Use of the key allows subscriber connectivity without revealing, to the caller or to the data center, sensitive contact information. Through a caller database, call initiation occurs by subscriber alias identification in a caller's communication device; thereby foregoing inclusion of sensitive contact information within the caller's communication device. Communication connectivity can be advertiser sponsored, with advertisements accompanying messages selected by matching profile information of targeted subscribers with participating advertiser provided profile information of desired targeted subscribers.

The search engine receives the search query and, in response to the search query, searches for relevant information pertaining to the problem, error, or failure, and sends a corresponding response to the network-enabled device. The response includes response data having some contextual association with the solution. The device receives the response, processes at least some of the response data to determine a course of action, and initiates that course of action.

A method and system is provided for analyzing potential repeatable values for placement into a data field based on user-defined criteria and includes analyzing relationships between documents for the purpose of correlating sender and receiver information into a context to more accurately populate type-ahead functions in repeatable data fields. Threaded messages are typically limited to those messages that are responses to responses or responses to an original message and are usually denoted by terms such as, for example, “forwarded” or “reply to” and where the history of the previous related message is included in the most recent message. However, the invention now expands correlation into non-thread related documents to achieve a higher correlation rate. The expanded documents may be any previous email or associated documents of a sender or receiver, including any documents defined by user criteria. In the case of stand-alone applications such as word processors, any user associated document, as defined by user criteria may be included in a contextual association for purposes of type-ahead analysis.

The method is characterized in that complex artificial feature extraction operations do not need to be carried out, external resources arealso not relied on, and compared with existing consistency analysis technology, the method provided by the invention has a great improvement in an accuracy rate, and has a better practical value.

A messaging system can initiate a communication with one or more users through via cell phone text messages, for example using the short message service protocol. These systems often need a way to correlate user responses with system requests or queries. This problem can present challenges because the email mailbox metaphor used by cell phone user interfaces generally allows users to reply to any previously sent messages, but no message context is automatically supplied. A system that may send multiple messages to a user needs a mechanism by which the system can correlate a user-sent response to one of potentially many system-sent requests or queries. Context correlation to resolve ambiguities can be based on one or more of a dialog-based solution, a token-based solution and a keyword-based solution.
