STUDY ON DOMAIN-SPECIFIC SEARCH ENGINE AND ITS AUTOMATED GENERATION

摘要：

As web information expands, vertical search engine plays a more and more important role in search industry. With being the best in specialized utilization field in mind, we develop domain-specific 114 search engine based on domain characteristics. Four advantages have been embodied in 114 search engine: quick response, high accuracy in domain, a significant enhancement of correlations between requirements and Info responses and automatically cross-domain engine building. Except short time-consuming and field generation automation, the reported experiments indicate that result pages of domain-specific 114 search engine have higher matching degrees towards user demands than the ones of Google in domain utilization.
