The Crawler of Specific Resources Recognition Based on Multi-thread

With the development of computer network and widely used of Internet, online information increases in broadband level exponentially, the difficulty and complexity of information retrieval also increase gradually, so the Crawler is developing rapidly. Crawler is a program that can auto collect information from internet. In this paper, we design and implement a multi-thread Crawler for specific resources. This Crawler has features of high accuracy, strong adaptability and high efficiency. Experiment results prove these.
