Abstract
One exemplary system receives a user query containing at least one fact and normalizes that query into a query footprint. Within the information-retrieval system, each document has a pre-computed document footprint. The document footprint can take into account the facts and/or anchor terms and their relationships to other facts, anchor terms and/or general terms within the document. The query footprint relates to each document footprint and any document footprint that is within a similarity threshold is selected. Finally, a signal associated with the documents associated with the selected document footprints is transmitted to the user.
