IMPLIE

IMPLIE (IMPLicit relation Information Extraction) is a program that extracts binary relations from English sentences where the relationship between the two entities is not explicitly stated in the text. IMPLIE supports the following target relations out-of-the-box: has nationality, has job title, has province, has city, and has religion. However, other relations can be supported by providing lists of keywords for new target relations. This is possible because IMPLIE uses a target independent syntactic language model.

For example, consider the following sentence:

      
  French journalist Paul Legall reported that all three hostages arrived safely at Athens International Airport. 
      

IMPLIE extracts the following binary relations:

      
  (French journalist Paul Legall; has nationality; French)
  (journalist Paul Legall; has job title; journalist)
  (Athens International Airport; has city; Athens) 
      

The code for IMPLIE can be found on github.

The system is described in a technical report.
