Embodiment Construction
[0039] In order to better understand the technical content of the present invention, specific embodiments are given together with the attached drawings for description as follows.
[0040] Such as figure 1 The flow chart of the incremental Bayesian algorithm training is given as shown in the figure. The Bayesian classifier introduced with incremental learning makes full use of the information of new samples, and uses the original classifier to predict and classify new samples. Correct or not to improve the model.
[0041] Such as figure 2 As shown, the topic crawler structure diagram based on the incremental Bayesian algorithm of the embodiment of the present invention. Its structure mainly includes several modules such as web page repository, web page downloader, web page parser, classifier, link priority queue and invalid link filtering.
[0042] Such as image 3 The figure shows the workflow flow chart of topic crawler based on incremental Bayesian algorithm. The inve...
