12. A computer program for collecting hypotheses of phrase pairs based on one or more seed pairs stored on a storage medium each consisting of first and second phrases representing a cause and a result, respectively, each of said phrase pairs consisting of two phrases assumed to represent causality, each of said first and second phrases including a combination of a noun and a predicate template, wherein the computer program is stored on a non-transitory computer readable medium and includes instructions configured to cause a processor to: determine a semantic relation pattern that matches a noun pair consisting of the nouns in said first and second phrases in each seed pair stored on the storage medium; and generate a new hypothesis by replacing a noun pair of a given seed pair of the one or more seed pairs with each of word pairs stored on the storage medium related to the semantic relation pattern determined to be matching said noun pair, wherein: semantic relation patterns are stored on the storage medium; each of the stored word pairs are related to any of semantic relation patterns stored on the storage medium; and each of the stored semantic relation patterns represents a semantic relation pattern between words; wherein the generation of the new hypothesis improves information extraction from electronically available documents.

The computer program of claim 12 , wherein the instructions are further configured to cause the processor to: filter new generated hypotheses such that only those relevant as phrase pairs representing causality are left.
