A transcript of a conference (e.g., a video conference, an audio conference, or a telephone call with two or more participants) is processed to extract a conference summary. Scores are determined for strings of the transcript that are used to select strings for inclusion in the conference summary. Determining the scores includes determining respective sentence vectors for strings. A sentence vector has elements corresponding to words in the transcript that are proportional to occurrences of the word in the string and inversely proportional to occurrences of the word in the transcript. A short video conference summary or a short audio conference summary is then generated using timestamps from the transcript associated with strings (e.g., sentences) that have been selected for inclusion in the conference summary. The short video or audio summary may be presented to users to enable efficient storage and transmission of conference information within a unified communications system.

Automated recording highlights for conferences

A contact center server obtains historical contact center data of a contact center by tracking contact center conditions. The contact center server trains, based on the historical contact center data, multiple modeling engines to generate agent demand data representing a number of agents working at a given time. The contact center server trains, based on the historical center contact center data and performance data of the multiple modeling engines, a combination engine to generate a combination of one or more modeling engines from the multiple modeling engines. The contact center server provides an output representing the trained combination engine and the multiple modeling engines.

Training modeling engines to predict contact center agent demand

A transcript of a conference (e.g., a video conference, an audio conference, or a telephone call with two or more participants) is processed to extract a conference summary. The transcript includes strings that are associated with respective timestamps and respective speaker identifiers. Speaker segments—sequences of consecutive strings attributed to the same speaker—are identified in the transcript. A speaker segment is selected based on its duration in time and one or more strings are selected from with the selected speaker segment for inclusion in the conference summary. A short video conference summary or a short audio conference summary is then generated using timestamps from the transcript associated with strings (e.g., sentences) that have been selected for inclusion in the conference summary. The short video or audio summary may be presented to users to enable efficient storage and transmission of information from the conference within a unified communications system.

Conference summary generation

Provided is an aggregation index structure and an aggregation index method for improving aggregation query efficiency. The aggregation index partitions streaming data through two dimensions of grouping and slicing, and then aggregates the partitioned data. The structure includes index metadata, a sliced data list and a detailed data store; the aggregation index method includes three parts: aggregation index definition, aggregation index creation and aggregation index query. The aggregation index structure and method provided by the present disclosure can greatly improve the efficiency of aggregation query, support the ad hoc aggregation query of PB-level data, complete the aggregation query of a large amount of data in seconds, support the insertion of new data at any time, and return the query results in minutes or even seconds latency in the event of changes of the query range conditions.

Provided is a method for reverse real-time matching based on event-driven graph patterns. The method includes definition of a graph pattern, establishment of reverse matching architecture and a reverse matching method; and the graph pattern is used for describing a spatial connection relationship among vertices and edges in a graph in a reverse order and attribute constraints thereof, and includes a linked list of matching steps and matching contexts. Reverse real-time matching of the graph pattern is realized according to the reverse matching architecture, and the problem of event-driven subgraph matching in a real-time scene is solved.

Speaker segment analysis for conferences

A transcript of a conference (e.g., a video conference, an audio conference, or a telephone call with two or more participants) is processed to extract a conference summary. A graphical user interface is presented that enables a user to edit highlighting to select portions of a conference recording for inclusion in the conference summary. The user can edit highlighting on strings of a transcript and/or on a playback slide bar and the highlighting edits are propagated to both of these interfaces. Video clips selected for inclusion in a summary based on timestamps of strings in a transcript may be extended forward in time to incorporate a nearest I-frame of video. The short video or audio summary may be presented to users along with a text summary of the conference to enable efficient storage and transmission of information from the conference within a unified communications system.
