Search Engine Research And Design

With the rapid development of internet and the rapid growth of web information, people want to be fast to search accurate information more and more difficult. While the search engine technology is used to collect, discover information, and understand information, and processing of information as a strategy in the internet. Search engine provide information retrieval services for users, which has played the role of information navigation. So search engine research has become the computer industry and academia conducting research and development targets.Search engine have been widely used in various fields as the most important information search tools in the Internet. However, due to the rapid increase in the amount of information networks and network information organization of the disorder, People's needs in improving gradually in the personality, intelligence of information services aspects. This paper presents a simplified search vector space model, which is based on the Robot of search engine system. Based on the traditional information retrieval technology, in this paper, which improved search algorithm, proposed a fast and accurate service architecture model, the system can Excavated valuable information from the database, and send to the customer. Also resolve this model involved in the data analysis and sequencing, and other key technical problems. The model has highly efficient and intelligent features. This paper also elaborated on several issues on the search engine technology. The main contents:1. Web mining and information retrieval theory.2. Information Retrieval and search engine's principles analysis.3. Detailed study PageRank algorithm, and PageRank algorithm has been used as an important ranking algorithm in robot-based search engine ranking algorithm.4. Achieve a Robot-based search engine search strategies for the design and the design strategy rankings. And PageRank algorithm used to calculate the value of grading pages in the design.
