This paper examines the differences between author generated keywords and automatically generated keywords in one area of scientific and technical literature. Using inverse frequency, keywords produced using both methods are examined using a maximum likelihood algorithm. By reducing the scope and size of the corpus of literature examined, this study more closely emulates the information gatheri...

It is one of the core issues of XML keywords search algorithm about putting the hierarchical structure information of XML data into the index and making it support the efficient keyword search algorithm. This paper proposed a new a retrieval algorithm which was based on LAF coding; HBA, a bottom-up XML keyword search algorithm, and it can support a variety of search semantic models effectively....

This paper describes a method of generating effective language models for voice query recognition and a new dialogue strategy for a voice activated QA system. By using multiple domain language models, better recognition accuracy is obtained for query utterances. In the proposed interactive dialogue strategy using multimodal user interface, users are requested to indicate correct keywords and in...
