VSEC: A Vertical Search Engine for E-commerce

With the explosion of e-commerce sites, querying information residing on these sites with high accuracy becomes a practical issue when designing next generation search engines. The inherent natures of general search engines limit their applications in scenarios where result quality is a critical concern. To overcome this difficulty, we build a Vertical Search Engine for e-commerce (VSEC), which crawls, deep-processes, index information of e-commerce sites of given topics and provide querying service of high quality. VSEC is characterized by two defining features: (1) multi-thread model is employed to speed up the crawling procedure; (2) index building and query answering is implemented on Lucene.Net. Experimental results show that our system has high retrieval efficiency and higher query accuracy and recall rate than general search engine.
