Research on Expectation Types and Common Sense Discovery in Chinese Concessive and Adversative Compound Sentences
Some expressions in natural language harbor rich implicit expectations and common sense,with constructions of concessive and adversative compound sentence like"Suiran(although)A,Danshi(but)B"serving as a prime example.From the perspective of applying linguistic knowl-edge to artificial intelligence,mining common sense from language aids in constructing a common sense knowledge base to support common sense reasoning.The research process involves a formalized operational flow of"negation → simplification → completion → generalization → connection,"extrac-ting the implicit expectations inherent in concessive constructions,demonstrating that pragmatic in-formation can also be extracted through formalized means.Depending on the causal relationship be-tween"A"and"(-)B(not B)"in the format,the expectations in concessive constructions can be cate-gorized into three types:intuitive reasoning-based expectations,experience-based expectations,and encyclopedia-based expectations.Based on the causal relationship and reasoning mode of"A"and"(-)B,"intuitive reasoning-based expectations can be further classified into six types:attribute analogy,attribute contrast,magnitude analogy,attribute inheritance,attribute value preservation,and attrib-ute value convergence.Along the dimensions of time and space,experience-based expectations can be divided into sequence-based expectations and co-occurrence-based expectations.Both experience-based and encyclopedia-based expectations can be generalized as common sense,which can be collected and constructed into a common sense knowledge base.Finally,examples are provided to illustrate how to use the extracted small-scale common sense knowledge base for Question Answering(QA)and Ab-ductive Inference.
