One Solution About Topic Web Crawler’s Greedy Search Strategy
Chen Jin-sen · Microelectronics & Computer · 2006
Topic web crawler search strategy is the core of professional search engine technology. However, the current topic search algorithms always exist large greedy It is difficult to find optimal solutions in the overall situation. Through comparative analysis found that despite Best-First algorithm having shortcomings, but its performance is optimal in several algorithms So based on Best-First algorithms it raised BS-BS algorithms. Then it evaluated BS-BS algorithm .And found that not only recall rate had improved, but could get the optimal solutions in the overall situation.
