| 摘 要： | 使用语音识别技术为搜索引擎提供语音查询接口，使得奇询概念的输入更为简便。但是，由于查询概念中存在大量的专有名词和名称，识别精度往往不高，影响搜索结果的准确率。该文提出一种在新闻领域内，利用新闻领域知识提高查询概念识别率的方法，通过计算语音识别结果与新闻概念库中概念的语音相似度确定备选结果，计算备选结果与辅助概念的新闻相关度来确定最终的查询概念。实验证明，该方法对新闻搜索引擎的查询概念的纠错收到了良好的效果。

| Abstract: | It makes inputting query concepts more convenient by providing oral query interface with the help of speech recognition technology. However, accuracy of recognition is low since lots of proper nouns and expressions exist in query concepts. This paper shows a method for improving the accuracy of recognition in news field by using context knowledge of news. It confirms the recognition result by calculating news similarity between assistant concepts and backup results, which are gained by calculating pinyin similarity between recognition and concepts in conception database. Experiment shows that it acquires more accurate results in web news search application. |
