Abstract：Search log name recognition has been a focus in Log Mining, which has direct impact on search engine’s retrieval efficiency and accuracy. The paper analyzes the drawbacks of name identification methods for long texts when applied to search logs, and proposes a method to identify Chinese names in search logs. The method employs the name internal word probability extracted from search query logs by the Conditional Random Fields, then estimates the credibility of person name according to the characteristics in the search log. Experimental results on Sogou query logs show that our approach reaches 81.97%accuracyand 85.81% recall on average, yielding F-measure of 83.79% .
