Improved algorithm about topic web crawler's search strategy
Junfeng Liu · Computer Engineering and Applications Journal · 2007
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 find that despite Best-First algorithm having shortcomings,but its performance is optimal in several algorithms.So based on Best-First algorithms it raises BS-BS algorithms.Then it evaluates BS-BS algorithm.And find that not only recall rate has improved,but can get the optimal solutions in the overall situation.
