Aligning semantic graphs for textual inference and machine reading
msra(2007)
摘要
This paper presents our work on textual inference and situates it within the context of the larger goals of ma- chine reading. The textual inference task is to deter- mine if the meaning of one text can be inferred from the meaning of another and from background knowledge. Our system generates semantic graphs as a representa- tion of the meaning of a text. This paper presents new results for aligning pairs of semantic graphs, and pro- poses the application of natural logic to derive infer- ence decisions from those aligned pairs. We consider this work as first steps toward a system able to demon- strate broad-coverage text understanding and learning abilities.
