| Abstract: | Thematic words extraction from a Chinese text not only can concentrate an article,but also can extract main ideas from a Chinese Web and help to achieve precise matching between online advertisement and a webpage.The paper presents a method of thematic words extraction based on Tongyici Cilin.The method not only has taken traditional factors affecting the weight of a thematic word into account,but also has considered the factors such as the appearance of relevant words,synonymy and lower words.Experiments have confirmed that the accuracy rate of thematic word extraction from a Chinese text can reach 83.25% using this method. |
