Patent number: 11640540Abstract: A method for assigning weights to a knowledge graph includes extracting information from a knowledge graph. The information including entities extracted from nodes of the knowledge graph and relations extracted from edges of the knowledge graph. A shortest path generator receives the extracted entities and relations, and potential assigned weights from a heuristic data repository. Weights for the edges of the knowledge graph are determined. The weights are assigned to the edges of the knowledge graph.Type: GrantFiled: March 10, 2020Date of Patent: May 2, 2023Assignee: International Business Machines CorporationInventors: Kshitij Fadnis, Kartik Talamadupula, Pavan Kapanipathi Bangalore, Achille Belly Fokoue-Nkoutche

Patent number: 11429876Abstract: One embodiment of the invention provides a method for natural language processing (NLP). The method comprises extracting knowledge outside of text content of a NLP instance by extracting a set of subgraphs from a knowledge graph associated with the text content. The set of subgraphs comprises the knowledge. The method further comprises encoding the knowledge with the text content into a fixed size graph representation by filtering and encoding the set of subgraphs. The method further comprises applying a text embedding algorithm to the text content to generate a fixed size text representation, and classifying the text content based on the fixed size graph representation and the fixed size text representation.Type: GrantFiled: March 10, 2020Date of Patent: August 30, 2022Assignee: International Business Machines CorporationInventors: Pavan Kapanipathi Bangalore, Kartik Talamadupula, Veronika Thost, Siva Sankalp Patel, Ibrahim Abdelaziz, Avinash Balakrishnan, Maria Chang, Kshitij Fadnis, Chulaka Gunasekara, Bassem Makni, Nicholas Mattei, Achille Belly Fokoue-Nkoutche
