Abstract  This paper analyzes the evaluation indexes of Web search engines using the epidemiological screening theory without gold standard. User experience score and user judgment are used as the prior information of Bayes estimation. Then it maks use of the MCMC(Markov Chain Monte Carlo)technology to estimate the sensitivity,specificity and detection rate of Baidu and Google(Simplified Chinese).
Key wordsSearch engine      Screening      Sensitivity      Specificity      User experience
