16. The computer program product of claim 15 , wherein the indication is stored as an Unstructured Information Management Architecture (UIMA) Common Analysis System (CAS) object, the operation further comprising determining that the first and second criteria are related criteria by: identifying a first concept in the first portion of the segment of unstructured text and a second concept in the second portion of the segment of unstructured text; determining a distance between a first concept node of an ontology and a second concept node of the ontology, wherein the first and second nodes of the ontology are related to the first and second concepts, respectively; computing a score for the first concept and the second concept, wherein the similarity score is based on the distance between the first concept node and the second concept node in the ontology and reflects a level of similarity between the first and second concepts; and prior to combining the first criterion and the second criterion into the composite criterion, determining that the similarity score exceeds a similarity threshold.
16. The computer program product of claim 15 , wherein the indication is stored as an Unstructured Information Management Architecture (UIMA) Common Analysis System (CAS) object, the operation further comprising determining that the first and second criteria are related criteria by: identifying a first concept in the first portion of the segment of unstructured text and a second concept in the second portion of the segment of unstructured text; determining a distance between a first concept node of an ontology and a second concept node of the ontology, wherein the first and second nodes of the ontology are related to the first and second concepts, respectively; computing a score for the first concept and the second concept, wherein the similarity score is based on the distance between the first concept node and the second concept node in the ontology and reflects a level of similarity between the first and second concepts; and prior to combining the first criterion and the second criterion into the composite criterion, determining that the similarity score exceeds a similarity threshold. 17. The computer program product of claim 16 , wherein the segment of unstructured text comprises a single criterion prior to identifying the first and second portions of the unstructured text, the operation further comprising: upon determining that (i) the score does not exceed the similarity threshold, and (ii) the anaphora does not relate the second concept to the first concept: refraining from combining the first and second criteria into a composite criteria; and storing an indication that the first and second criteria are distinct criteria for the policy document.
