Abstract: 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.

Abstract: A process of the production of high surface area tantalum and/or niobium powders via the reduction of the corresponding tantalum and/or niobium oxides is disclosed, wherein the reduction is carried out by reacting the tantalum and/or niobium oxides with at least one metal halide selected form the group consisting of halides of Mg, Ca, Sr, Ba and Ce, and an alkali metal at elevation temperature so as to form the tantalum and/or niobium powders. The process of the present invention has the advantages of: simple operation, the tantalum and/or niobium powders obtained have high surface area, high purity, good flowability, therefore are particularly suitable for manufacturing electrolytic capacitors.
