Systems and methods for generating single-node representations in graphs composed of linked nodes. The present technology enables dynamic generation of individual node embeddings in sub-linear time (less than O(n), where n is the number of nodes in the graph G), using only the PPR vectors of the individual nodes and a random projection to reduce the dimensionality of the PPR vectors of that node. In one example, the present technology includes a computer-implemented method comprising: obtaining, from a database, a graph having a plurality of nodes; generating, for a given node of the plurality of nodes, a personal PageRank vector; and producing, for the given node, an embedding vector by randomly projecting the personal PageRank vector, wherein the embedding vector has a lower dimensionality than the personal PageRank vector.

System and method for generating context-aware pageranks according to certain embodiments. For example, a method includes: generating a plurality of vector elements of a pagerank vector for a page based on a plurality of search contexts, each vector element of the plurality of vector elements corresponding to a respective search context, each search context of the plurality of search context corresponding to a respective security level of a plurality of security levels; obtaining one or more bleed factors for the plurality of search contexts, each bleed factor of the one or more bleed factors associated with two search contexts of the plurality of search contexts having two adjacent security levels of the plurality of security levels; and adjusting at least one vector element of the plurality of vector elements based on the one or more bleed factors.
