摘要: In a corpus of scientific articles such as a digital library, documents are connected by citations and one document plays two different roles in the corpus: document itself and a citation of other documents. A Bernoulli Process Topic (BPT) model is provided which models the corpus at two levels: document level and citation level. In the BPT model, each document has two different representations in the latent topic space associated with its roles. Moreover, the multi-level hierarchical structure of the citation network is captured by a generative process involving a Bernoulli process. The distribution parameters of the BPT model are estimated by a variational approximation approach.

摘要: The present invention provides a system with virtual audio driver for the VoIP (voice over internet protocol) environment. The virtual audio driver is computer software, and it can be implemented by diverse possibilities. Including being implemented by different programming languages; supporting various operating systems (OS) and so on. It should be appreciated that the virtual audio driver is used for transferring the voice data, instead of producing the sounds. Besides, the present invention also provides a virtual telephone interface. After combining the virtual audio drivers and the virtual telephone interface with the VoIP client applications, users can simply answer VoIP calls from several VoIP client applications by single software.

摘要: A teleconference system comprises VoIP server, a rootnode presider terminal, a first level conference element and a second level conference element. The first level conference element includes the rootnode presider terminal and at least one first participant terminals as childnode of the rootnode presider terminal, wherein at least one of the first participant terminals is the candidate to be selected as second level presider terminal. The second level conference element includes the second level presider terminal and at least one second participant terminals as childnode of the second level presider terminal. The VoIP server is coupled to the rootnode presider terminal, first participant terminals and second participant terminals.
