Sifa Zhang · Computer Engineering and Applications Journal · 2012
Vertical search engines are the industrial division of comprehensive search engines,and in this paper,according to the industry characteristics,the overall demand and the workflow of geosciences field,thePaodingjieniu Chinese word segmentation algorithm,the subject-correlation judgment function and theSubject Management option are added to the Nutch system,thus establishing the vertical search engine for geosciences.The online test and result comparison show that this system has obvious advantages compared with universal search engines,making it more accurate to locate and search geo-information.Besides,the system has good extensibility and versatility,providing some reference to the vertical search engine research and development.
