Analyzer of subject search
A human being is often able to interpret a search query, determine what the user wants, evaluate the information on the Web and form the search results better than a machine. For this reason, the results formed by an expert are always better than those of an algorithm.
This analyzer monitors daily the search results for a set of queries, for which the corresponding links have been selected by experts. It calculates the number of sites found by each search engine that were on the experts' list. For each query, the percentage of similarity between algorithmic and expert results is calculated.
As an expert opinion, the output of the expert system Neuron is used. The aggregate indicator of this analyzer is the proportion of results matching the expert opinion, regardless of the position of the matching site(s).
The best search engine is the one with highest value of aggregate indicator. In the informer, the search engines are sorted by the aggregate indicator.
Currently, 18 queries are evaluated. The number of the queries will be increased.
