Method and apparatus for improving querying

摘要

In a method of improving querying, a plurality of items of information are transformed into a plurality of vectors, where each item of information of the plurality of items of information is mapped to a respective vector of said plurality of vectors. A plurality of vectors is associated with a subset of nodes selected from a plurality of nodes. Each vector associated with a respective node of said plurality of nodes is based on a similarity between each vector of said plurality of vectors.
