A cooperative conversational voice user interface is provided. The cooperative conversational voice user interface may build upon short-term and long-term shared knowledge to generate one or more explicit and / or implicit hypotheses about an intent of a user utterance. The hypotheses may be ranked based on varying degrees of certainty, and an adaptive response may be generated for the user. Responses may be worded based on the degrees of certainty and to frame an appropriate domain for a subsequent utterance. In one implementation, misrecognitions may be tolerated, and conversational course may be corrected based on subsequent utterances and / or responses.

A system and method for organizing knowledge in such a way that humans can find knowledge, learn from it, and add to it as needed is disclosed. The exemplary system has four components: a knowledge base, a learning model and an associated tutor, a set of user tools, and a backend system. The invention also preferably comprises a set of application programming interfaces (APIs) that allow these components to work together, so that other people can create their own versions of each of the components. In the knowledge web a community of people with knowledge to share put knowledge in the database using the user tools. The knowledge may be in the form of documents or other media, or it may be a descriptor of a book or other physical source. Each piece of knowledge is associated with various types of meta-knowledge about what the knowledge is for, what form it is in, and so on. The information in the knowledge base can be created specifically for the knowledge base, but it can also consist of information converted from other sources, such as scientific documents, books, journals, Web pages, film, video, audio files, and course notes. The initial content of the knowledge web comprises existing curriculum materials, books and journals, and those explanatory pages that are already on the World Wide Web. These existing materials already contain most of the information, examples, problems, illustrations, even lesson plans, that the knowledge web needs. The knowledge base thus represents the core content (online documents or references to online or offline documents); the meta-knowledge that was created at the time of entry; and a number of user annotations and document metadata that accumulate over time about the usefulness of the knowledge, additional user opinions, certifications of its veracity and usefulness, commentary, and connections between various units of knowledge.

A method and system for sharing knowledge is disclosed. The method and system comprises receiving information input into a database and organizing items of information in the database. The method and system further includes collecting ratings and comments associated with each item of information and allowing users to access and sort items of information according to selected rating criteria in order to find the most reliable and / or valuable information from the database. In a second aspect, the present invention including an interface for providing information concerning a subject is disclosed. The interface comprises a first area that shows the subject and contributor name; and a second area that shows the content of the information item. The interface includes a third area that shows rating related to the subject; and a fourth area that allows users to submit ratings for the information item. Accordingly, a knowledge sharing system and interface are provided which allows every member of a knowledge sharing group to benefit from aggregate knowledge, experience and opinions of other members of the group. The system and method allows individual members to easily locate the information from a collectively generated knowledge base that is most consistent with that individual's personal measures of value in the information.

An information sharing area, employed by all conferees for sharing information (object) or personal knowledge transmitted via information processors from conferees, and an editing display area, employed for editing a structure of the information (object) or shared knowledge, can be definitely distinguished from each other and displayed in a large display device commonly visible from all conferees. When the areas are displayed in the large display device and one of the objects displayed in the information sharing area is designated, the designated object is displayed at a desired location in the editing display area and can be edited through cooperative works by all conferees centering around a conference chairman.

A public key and digital signature is provided using a private key of a public-private key pair in an elliptic curve digital signature algorithm (ECDSA) by: identifying domain parameters of an elliptic curve for use in elliptic curve cryptography, the domain parameters including an initial generating point; transforming the generating point into a new generating point as a deterministic function; generating the public key as a deterministic function of the private key and the domain parameters, in which the new generating point is substituted for the initial generating point; and generating the digital signature as a function of the private key and the domain parameters, in which the new generating point is substituted for the initial generating point.

Facilitating communication using a digital signature includes: communicating software to a first party; receiving from the first party public keys of public-private key pairs generated using the software; and recording in a database the public keys in association with information pertaining to the software. The key pairs have the same private key. The software additionally provides digital signatures utilizing this private key. Each public key of these key pairs is generated, in part, based on data that is specified by the first party.
