11. A system for automatically identifying entity-value pairs from text, the system comprising: a storage device that stores a set of instructions; and at least one processor that executes the set of instructions to: receive an electronic text file including a text corpus comprising a plurality of words; generate by parsing the text corpus, a corresponding parse tree structure in memory, including nodes of each of the plurality of words having edges based on the parts of speech of the plurality of words; identify a plurality of entity-value pairs in the text corpus that correspond to a predetermined entity and a predetermined value related to the predetermined entity by a predetermined attribute, wherein each of the entity-value pairs comprise an entity and a value; extract, based on the parse tree structure, a plurality of parse tree paths to traverse the tree structure from a node corresponding the entity to a node corresponding to the value of the plurality of entity-value pairs; generate a data record including an indication of how accurately the extracted plurality of parse tree paths correspond to the predetermined attribute, based on at least one of the plurality of parse tree paths; and validating an entity-value pair based on the data record.

The system of claim 11 , wherein the text corpus is from a plurality of sources and wherein the at least one processor further executes the instructions to determine a number of sources from which a given parse tree path of the plurality of parse tree paths was extracted.
