| Summary: | 碩士 === 國立中正大學 === 資訊工程所 === 93 === With the rapid growth of Internet and popularity of on-line shopping, there are lots of users to purchase product through the Internet. In this paper, we implement an EC search engine that can help user find product information efficiently and correctly. The EC search engine fetches the pages in EC sites, and extracts product information from them. Users can search product information through the search interface. In order to help user browse the search result and find required product, we use several schemes to present the search result. We will cluster the search result such that users can browse the search result efficiently. If users interested in one of these clusters, he/she can search the desired cluster further with the original query term.
In addition to product search, we also provide Product Watch that help user get up-to-date product information. It periodically searches EC sites and extracts product information to compare with old product information. It will notify users the latest product information.
