IMAGE ANALYTICS QUESTION ANSWERING
First Claim
1. A computer-implemented method for predicting answers to questions concerning medical image analytics reports, the method comprising:
- splitting a medical image analytics report into a plurality of sentences;
generating a plurality of sentence embedding vectors by applying a natural language processing framework to the plurality of sentences;
receiving a question related to subject matter included in the medical image analytics report;
generating a question embedding vector by applying the natural language processing framework to the question;
identifying a subset of the sentence embedding vectors most similar to the question embedding vector by applying a similarity matching process to the sentence embedding vectors and the question embedding vector; and
using a trained recurrent neural network (RNN) to determine a predicted answer to the question based on the subset of the sentence embedding vectors.

Abstract
A computer-implemented method for predicting answers to questions concerning medical image analytics reports includes splitting a medical image analytics report into a plurality of sentences and generating a plurality of sentence embedding vectors by applying a natural language processing framework to the plurality of sentences. A question related to subject matter included in the medical image analytics report is received and a question embedding vector is generated by applying the natural language processing framework to the question. A subset of the sentence embedding vectors most similar to the question embedding vector is identified by applying a similarity matching process to the sentence embedding vectors and the question embedding vector. A trained recurrent neural network (RNN) is used to determine a predicted answer to the question based on the subset of the sentence embedding vectors.
