15. A system comprising: a memory coupled to a bus system, wherein the memory comprises computer useable program code; and one or more processing units, wherein the one or more processing units execute the computer useable program code to provide a service configured to process one or more domain-independent entity augmentation tasks corresponding to one or more queries, including to access a plurality of indexes preprocessed offline from a plurality of relational tables obtained from at least one corpus, and to respond to a query corresponding to an entity augmentation task with data obtained via the plurality of indexes, including to identify a plurality of seed tables via the index, compute a first score for a seed table of the plurality of seed tables based on direct mapping of a query table included in the query with the seed table, compute a second score for the seed table based on indirect mapping of a relational table with the seed table, aggregate the first and second scores, and return a final prediction based at least partially upon the aggregation of the first and second scores to complete an entity augmentation task to respond to the query, the seed tables representing tables that have complete records in common with the query table.
18. The system of claim 15 wherein the indirect mappings are based upon topic sensitive pagerank over a graph built from the plurality of seed tables.
