This paper presents four novel techniques for open-vocabulary spoken document retrieval: a method to detect slots that possibly contain a query feature; a method to estimate occurrence probabilities; a technique that we call collection-wide probability re-estimation and a weighting scheme which takes advantage of the fact that long query features are detected more reliably. These four techniques have been evaluated using the TREC-6 spoken document retrieval test collection to determine the improvements in retrieval effectiveness with respect to a baseline retrieval method. Results show that the retrieval effectiveness can be improved considerably despite the large number of speech recognition errors. 相似文献

The aim of this study was to understand the relationships between self‐compassion, positive affect, negative affect, and variables representative of positive body image for college women. Regression analyses indicated that self‐compassion and affect accounted for 39% and 30% of the variance, respectively, in body appreciation and body image quality of life. Mediational analyses demonstrated that positive affect mediated the relationships between self‐compassion and both indicators of body image. Implications for college counseling are discussed. 相似文献

QuickChange mutagenesis is the method of choice for site-directed mutagenesis (SDM) of target sequences in a plasmid. It can
be applied successfully to small plasmids (up to 10 kb). However, this method cannot efficiently mutate bigger plasmids. Using
KOD Hot Start polymerase in combination with high performance liquid chromatography (HPLC) purified primers, we were able
to achieve SDM in big plasmids (up to 16 kb) involving not only a single base change but also multiple base changes. Moreover,
only six polymerase chain reaction (PCR) cycles and 0.5 μl of polymerase (instead of 18 PCR cycles and 1.0 μl of enzyme in
the standard protocol) were sufficient for the reaction. 相似文献
