METHODS AND SYSTEMS FOR GENERATING AND TRAVERSING DISCOURSE GRAPHS USING ARTIFICIAL NEURAL NETWORKS

摘要

A system for generating and performing inference over graphs of sentences standing in directed discourse relations to one another, comprising a computer process, and a computer readable medium having computer executable instructions for providing: tree-structured encoder networks that convert an input sentence or a query into a vector representation; tree-structured decoder networks that convert a vector representation into a predicted sentence standing in a specified discourse relation to the input sentence; couplings of encoder and decoder networks that permit an input sentence and a “query” sentence to constrain a decoder network to predict a novel sentence that satisfies a specific discourse relation and thereby implements an instance of graph traversal; couplings of encoder and decoder networks that implement traversal over graphs of multiple linguistic relations, including entailment, contradiction, explanation, elaboration, contrast, and parallelism, for the purposes of answering questions or performing dialogue transitions; and a spiking neural network implementation of the aforementioned system components.
