Method of extracting the relation between entities from biomedical text data

摘要

PURPOSE: A deduction method is provided to automatically update or extract information by deducing relationships between objects from raw text data. CONSTITUTION: A grammatical dependency graph is created by analyzing sentences within a document(1410). The shortest dependent path which connects objects is deduced from the grammatical dependency graph(1420). An instance which is necessary to learn a relationship between objects is created from the shortest dependency path(1430). A sub structure is created from the instance. The objects are measured by using the sub structure(1440). The relationship between objects is deduced from the similarity(1450).
