But Keyword search is hard to directly improve search quality because lots of keyword-matched nodes may not contribute to the results. And in many applications, the goal is to ...

We explore the potential of using keyword-aware language modeling to extend the ability of trading higher false alarm rates in exchange for lower miss detection rates in LVCSRbased keyword search (KWS). A context-dependent keyword language modeling method is also proposed to further enhance the keyword-aware language modeling framework by reducing the number of false alarms often sacrificed in ...

As such, silence has the potential to affect both speakers-the source of the silence-and listeners-those attending to the speaker. Although the topic of silence is widely...

This paper proposes a real-time query method for distributed database requirement information. First, we propose to extract the information according submitted keyword. Then, establish model of demand and classification model, using multivariate hash algorithm When there is keyword, proposed directly reads data above ring based on keyword improve efficiency. Extensive experimental results indic...
