Generating and using socially-curated brains

A computer-implemented method, comprising:

• determining, from a stored plurality of social objects, a first group of social objects, each social object of the first group of social objects comprising a link to one of a plurality of link objects on a network;
• filtering the first group of social objects in order to determine a plurality of filtered social objects, the filtering comprising selecting social objects from the first group of social objects that each comprise one or more links to link objects that have also been linked to by one or more other social objects;
• accessing each of the link objects linked to by the plurality of filtered social objects;
• generating, using the link objects linked to by the plurality of filtered social objects, a matrix comprising a plurality of vectors;
• producing a singular value representation of the matrix by performing Singular Value Decomposition (SVD) on the matrix;
• and
• performing a query using at least a portion of the singular value representation of the matrix.

A non-transitory computer-readable medium comprising software, the software when executed by one or more processing units operable to perform operations comprising:

• determining, from a stored plurality of social objects, a first group of social objects, each social object of the first group of social objects comprising a link to one of a plurality of link objects on a network;
• filtering the first group of social objects in order to determine a plurality of filtered social objects, the filtering comprising selecting social objects from the first group of social objects that each comprise one or more links to link objects that have also been linked to by one or more other social objects;
• accessing each of the link objects linked to by the plurality of filtered social objects;
• generating, using the link objects linked to by the plurality of filtered social objects, a matrix comprising a plurality of vectors;
• producing a singular value representation of the matrix by performing Singular Value Decomposition (SVD) on the matrix;
• and
• performing a query using at least a portion of the singular value representation of the matrix.
