Abstract:
A method and system for processing contextual information relating to an exchange of a conversation over a communication channel is provided. Several users, and/or service providers are allowed to specify a set of rules relating to a conversation channel. Contextual information, including information relating to the specified set of rules and conditions of the users, is exchanged among the users and/or several service providers when one user requests to initiate a communication channel. The received contextual information is processed to extract a set of rules and the current conditions of users. If the current conditions of the users satisfy the set of rules, a corresponding communication channel is established among the users. However, additional contextual information may be received and processed whenever there is a change in the contextual information during the conversation. Appropriate actions to the existing communication channel may be determined based on the changes.
Abstract:
A method and system for communicating a variable set of contextual information relating to a conversation over a communication channel is provided. When the contextual information is exchanged, any authorized sending party of the contextual information can change the scope, content, or amount of the contextual information that is transmitted to a next receiving party in a determined communication channel path. Before transmitting the contextual information, a desirable scope of the contextual information may be determined based on the next receiving party, in conjunction with the sending party's rules. The contextual information may be updated by adding new contextual information and/or deleting part of the contextual information which is outside of the scope. No contextual information may be transmitted if the next destination desires no contextual information or does not have capabilities to receive any contextual information.
Abstract:
A method and system for notifying a push-to-talk enabled user of an event. The method includes the steps of: receiving event data to be provided to a user; determining a push-to-talk configuration including carrier information for the user; and based on the push-to-talk configuration, providing the event data and user identification information to a carrier identified in the carrier information. The system may include an aggregation service controller; a text to speech converter; a user PTT connection mapping database; an online service interface; and a PTT service provider interface.
Abstract:
An integrated circuit (IC) card is presented comprising an input/output (I/O) interface and a smart card development interface (SCDI), coupled to the I/O interface, to receive and identify debug frames interlaced within a normal communication flow between the IC card and a host system.

Abstract:
This invention concerns a new process for the catalytic carbonylation of certain aryl halides or aryl tosylates to amides by use of a complex of palladium and at least one ligand. More specifically, the invention concerns carbonylation of halogenoaromaticsulfonamides or tosylatoaromaticsulfonamides to saccharin, saccharin analogues or their salts.
Abstract:
Low valent transition metal complexes containing small cone angle phosphine or arsine ligands efficiently catalyze addition of aldehydes to compounds or groups having a C--H bond activated by a nitro or nitrile group, to provide nitroalcohols or cyanohydrins, respectively.
Abstract:
Generally described, the present invention provides the ability to process digital voice conversations to identify data packets containing content of interest and to further process the identified data packets. More specifically, mining profiles may be developed identifying particular types of content that is to be mined and further identifying what is to be done when data packets containing such content is located. A system may search a digital voice conversation for the data packets containing the content and perform processing on the data packets once identified.
Abstract:
A system and method for efficiently reducing transcription error using hybrid voice transcription is provided. A voice stream is parsed from a call into utterances. An initial transcribed value and corresponding recognition score are assigned to each utterance. A transcribed message is generated for the call and includes the initial transcribed values. A threshold is applied to the recognition scores to identify those utterances with recognition scores below the threshold as questionable utterances. At least one questionable utterance is compared to other questionable utterances from other calls and a group of similar questionable utterances is formed. One or more of the similar questionable utterances is selected from the group. A common manual transcription value is received for the selected similar questionable utterances. The common manual transcription value is assigned to the remaining similar questionable utterances in the group.
