A system and method for enhancing e-commerce using a natural language interface. The natural language interface allows the user to formulate a query in a natural language form, rather than in conventional search terms. The natural language interface provides the user with a "user friendly" interface. The natural language interface can process a query even if there is not an exact match between the user formulated search words and the content in the database. Furthermore, the natural language interface is capable of processing misspelled queries or queries having syntax errors. The method for enhancing e-commerce using a natural language interface comprises the steps of accessing a user interface provided by a service provider, entering a query using a natural language interface, the query being formed in a natural language, processing the query by the natural language interface, searching a database using the processed query, retrieving results from the database, and providing the results to the user. The system for enhancing e-commerce on the Internet comprises a user interface for receiving a query in a natural language form, a natural language interface coupled to the user interface for processing the query, a service provider coupled to the user interface for receiving the processed query, and one or more databases coupled to the user interface for storing information, wherein the system searches the databases using the processed query and provides the results to the user through the user interface.

Method for web based language learning that empowers self-directed learners by introducing measurement within an integrated system of context-based non-didactic learning. Measurement enables self-directed learners to set goals and observe their own achievements; to make sure that learning material matches their specific vocabulary; and to establish a priority for study that suits their needs. Measurability is achieved within a system where words and lexical phrases are chosen by the learner from familiar content in an integrated system of listening, reading, pronunciation, writing and structured conversation. A database system is incorporated which enables the learner to create individual word or phrase card files that are then tagged with additional identifiers for use in creating custom lists to assist in the learning process. Additional feedback is provided by an automated writing correction program that checks for syntax errors in the learner's written work.

The present invention provides a method of correction of misspelled, confused words and grammar errors in a text, as well as a computer system employing this method. The method of the invention is user-interactive, which means that, when implemented by a computer system, the interaction between the user and the system is employed with the aid of the user-system interface. In the method of the invention the method detects misspelled and confused words, where some of the detected confused words could be grammar errors, and provides user with the correction alternatives for each such word. In response, the user can chose an appropriate correction, mark the word as correct or require other correction alternatives. The user-system dialog, which is intended to improve the correctness of the text, is repeated until all the words-in-question are corrected or marked by the user as correct.

Techniques are disclosed for enabling a validating parser to interpret a schema, where that schema may have been extended to multiple levels, and to perform the validation of a structured document according to the extended schema while still allowing a consumer application to request objects or events that are cast at some different level of the schema (including the base schema). Validating the source document according to an extended (i.e., more specific) schema enables improved detection of syntax errors. At the same time, casting objects and events from the parsed document to a level requested by the consumer application allows the consumer to receive only those objects or events for which it is adapted, without requiring the consumer application to include extra code to deal with objects or events it does not recognize in the parser's output. Preferably, the parser simply discards those objects or events which this consumer is not interested in receiving.

A voice-actuated system is described that allows voice authentication of on-line secure commands, such as purchases, by one or more designated users. It allows for an account to have multiple signatories that are required to approve a secure command. A user speaks commands into a local microphone, or in another embodiment, into a mobile device. A command recognition device identifies a secure command and sends it to a spectrum/cadence device to analyze spectrum and/or cadence. Also, the voice input may be sent to a word count/grammar device to analyze word counts and grammar errors to identify the user. Once identified, the account of user may be found and contact information for other signatories is acquired. The signatories are contacted and their identities are verified by comparison of their voices to pre-stored voice samples of the signatories.

Described are techniques for obtaining grammar updates. A grammar service receives a notification regarding a grammar update applied to a target. The grammar update is an update to a command syntax used by said target. The grammar service sends an update request to said target to obtain said grammar update. The target sends to the grammar service an update response including said grammar update. Also described are techniques for processing a command line. One of a plurality of rule sets is selected. The command line is parsed at said client using said selected rule set. If parsing did not result in a syntax error, a command request is sent from said client to said target. In response, the client receives a command response including information regarding a version of syntax rules currently used on said target.

A method of correcting job control language (JCL) jobs scans a JCL job against a set of JCL syntax rules. The method automatically corrects any syntax errors discovered during the scanning, thereby forming a corrected JCL job. The method then runs the corrected JCL job. If the corrected JCL ends abnormally due to an execution error, the method then automatically determines if the execution error is recoverable. If the execution error is recoverable, the method automatically corrects the recoverable error to form a recovered corrected JCL job. The method reruns the recovered corrected JCL job.
