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.
Claims14
A computer-implemented method comprising:
- receiving a query wherein the query comprises at least one factual description;
- transforming the query into a query footprint;
- in response to the query, identifying a document having a pre-computed document footprint related to the query footprint by a similarity threshold;
- and
- transmitting a signal representative of the document.
A system comprising:
- a server for receiving a query, the server including a processor and a memory, the query comprising at least one factual description;
- means for transforming the query into a query footprint;
- means for identifying, in response to the query, a document having a pre-computed document footprint related to the query footprint by a similarity threshold;
- and
- means for transmitting a signal representative of the document.
