1. A system, comprising: one or more memory units operable to store a plurality of tweets; and one or more processing units operable to: determine, from the stored plurality of tweets, a first group of tweets, each tweet of the first group of tweets comprising a link to one of a plurality of link objects on the Internet; filtering the first group of tweets in order to determine a plurality of filtered tweets, the filtering comprising selecting tweets from the first group of tweets that each comprise one or more links to link objects that have also been linked to by one or more other tweets; access each of the link objects linked to by the plurality of filtered tweets; generate, using the link objects linked to by the plurality of filtered tweets, a matrix comprising a plurality of vectors; produce a singular value representation of the matrix by performing Singular Value Decomposition (SVD) on the matrix; and perform a query using at least a portion of the singular value representation of the matrix.
