Synchronizing a data stream with an associated metadata stream by receiving a data stream and a metadata stream having a plurality of metadata events associated with the data stream, identifying within the data stream a plurality of data events, matching each of the data events to one of the metadata events in accordance with a matching criterion, and synchronizing the data stream with the metadata stream by effecting a relative time shift between the metadata stream and the data stream in accordance with a time shift adjustment value that results in the smallest sum of absolute differences between time indices of each matched data event and metadata event.

Synchronization of data streams with associated metadata streams using smallest sum of absolute differences between time indices of data events and metadata events

Methods and systems for social analysis in multi-participant meetings provide for receiving a data stream of a multi-participant meeting, wherein multiple topics are discussed. The data stream is analyzed to detect topics and to define topical sub-activities that are performed by at least a portion of the participants. Contributions to a topic by two of the participants in the topical sub-activities are identified and evaluated. A connection weight between the two participants is calculated based on the evaluation of their respective contributions.

Social analysis in multi-participant meetings

A method, system and computer program product are provided for social analysis in multi-party meetings. The method includes receiving a data stream of a multi-participant meeting and identifying participants' contributions in the data stream. The method also includes detecting a sub-activity within the data stream in which two or more participants are active and calculating a connection weight between two participants based on contributions in a sub-activity. Calculating a connection weight between two participants includes increasing a weighting of two participants that interact in the same sub-activity. The method also includes integrating the connection weight between two participants into a weighted social network.
