A focused crawler traverses the web selecting out relevant pages according to a predefined topic. While browsing the internet it is difficult to identify relevant pages and predict which links lead to high quality pages. This paper proposes a topical crawler for Vietnamese web pages using greedy heuristic and genetic algorithms. Our crawler based on genetic algorithms uses different recombination operators in the genetic algorithms to improve the crawling performance. We tested our algorithms on Vietnamese newspaper VnExpress websites. Experimental results show the efficiency and the viability of our approach.
