Claim 0:
1. A computer-implemented method for training an artificial intelligence based information retrieval model by weak supervision, comprising the steps of:
(a) generating, without human intervention, a pseudo-query including one or more keywords extracted from each passage in a corpus using a keyword extraction technique, the corpus being stored in a storage and including a plurality of passages;
(b) generating, without human intervention, a pseudo-label using an information retrieval model based on unsupervised learning from the pseudo-query generated in the step (a) and the corpus; and,
(c) training the artificial intelligence based information retrieval model using the pseudo-label generated in the step (b),
wherein the step (b) including the steps of:
(b1) retrieving M passages from the corpus using the information retrieval model based on unsupervised learning;
(b2) labelling the top m passages among the M passages retrieved in the step (b1) as positive; and
(b3) labelling at least some of the remaining passages among the M passages as negative.
