  • Methods and systems for selecting potentially erroneously ranked documents by a machine learning algorithm
    Patent number: 10642670
    Abstract: A method and a system for selecting a potentially erroneously ranked document in a set of search results responsive to a query comprising receiving the set of search results from the search engine server, each document of the set of search results having a relevance score and a feature vector generated by an MLA, computing for each possible pair of documents a first parameter indicative of a level of difference in the relevance scores of the documents of the pair of documents and a second parameter indicative of a level of difference in the feature vectors of the documents of the pair of documents, computing a verification score based on first parameter and the second parameter, the verification score indicative of a level of misalignment between the relevance scores and the feature vectors, selecting and marking the pair of documents associated with an extreme verification score for verification.
