The present invention is directed to a system, method and computer program
for automatically extracting and mining relations and related entities
from unstructured text. A method in accordance with an embodiment of the
invention includes: extracting relations and related entities from
unstructured text data, representing the extracted information into a
graph, and manipulating the resulting graph to gain more insight into the
information it contains. The extraction of relations and related entities
is performed first by automatically inducting pattern and second by
applying these induced patterns to unstructured text data. For each
relation and entity, several features are extracted in order to build a
graph whose nodes are entities and edges are relations.
