A price comparison system based on Lucene

Lots of online shopping systems (OSS) are proposed and used practically due to the rich opportunities provided by the Internet. The traditional OSS, however, essentially provides basic browsing via category and "advanced" keyword without any analysis. The paper presents a price comparison system of online products to show all the possible prices of products for customers. In particular, the proposed system develops a multithreaded crawler to implement web information crawling, and uses Lucene, a very popular full-text search library, to implement the data indexing and retrieval. The experimental results demonstrate that the proposed system improves shopping efficiencies for the consumers in a flexible and advanced way.
