Velocity estimation of cellular terminals in urban environment using ray tracing

Abstract: The paper discusses the problem of estimating the velocity of a mobile cellular terminal within an urban, multipath-rich environment, using available geographical information such as terrain and building maps. The method suggested in the paper is the use of ray tracing in order to characterize the propagation environment. The paper discusses the usage of Doppler processing of a signal received from a single antenna and suggests using a two stage algorithm — location followed by velocity estimation. The paper presents an algorithm and an error analysis describing the potential sources of errors encountered in implementation including inaccuracies in the geographical and network databases, measurement accuracy and location accuracy.

Determination of prominent phrases in multi-channel interactions by multi-feature evaluations

Abstract: A method for determining prominent keyphrases in interactions, comprising, receiving keyphrases of numerous interactions received via a plurality of channels that comprise apparatuses for conveying the interactions according to the media thereof, quantitatively evaluating each keyphrase by a plurality of different metrics thereby yielding a corresponding plurality of values, and linearly combining the plurality of the values with a corresponding plurality of coefficients associated with a channel via which an interaction having said keyphrase is received, thereby providing a score of said keyphrase, and based on a condition related to the scores of the keyphrases, selecting at least one keyphrase as an at least one prominent keyphrase, wherein the method is at least partially performed by an at least one computerized apparatus configured for interfacing with the apparatuses of the plurality of the channels.

System and method for generating metadata for a recorded session

Abstract: System and method for completing metadata for a recorded session. A recorder may initiate a recording of a session to produce a recorded session. The recorder may mark the recorded session as an incomplete or bad session. The session may be inserted into a bad sessions list. The bad sessions list may be examined and metadata related to sessions included therein may be used to update an operational database. Other embodiments are described and claimed.

Spare resource election in a computing system

Abstract: A computing system comprising multiple computing resources in which one resource assumes spare status using a spare election algorithm. According to the algorithm each computing resource on initialisation requests permission to assume spare state from the other computing resources. Then if all of the other computing resources grant the permission the requesting computing resource assumes spare state. If one of the other computing resources does not grant the permission to the requesting resource then the requesting resource assumes normal state.

System and method for contact center agent guidance with feedback

Abstract: In a method for providing guidance to agents of a contact center, a server of an agent guidance system provides a list of key selling points to a plurality of workstations. Each of the workstations is associated with an agent of the contact center. Each key selling point of the list is associated with an effectiveness status. The server receives from a workstation feedback related to an effectiveness of a key selling point of the list. The effectiveness status of a key selling point of the list is automatically modified in accordance with the received feedback. The server provides to the workstations a modified list that incorporates the modified effectiveness status.
