Patent number: 11436532Abstract: The disclosed embodiments provide a system that identifies duplicate entities. During operation, the system selects training data for a first machine learning model based on confidence scores representing likelihoods that pairs of entities in an online system are duplicates. Next, the system updates parameters of the first machine learning model based on features and labels in the training data. The system then identifies a first subset of additional pairs of the entities as duplicate entities based on scores generated by the first machine learning model from values of the features for the additional pairs and a first threshold associated with the scores. The system also determines a canonical entity in each of the duplicate entities based on additional features. Finally, the system updates content outputted in a user interface of the online system based on the identified first subset of the additional pairs.Type: GrantFiled: December 4, 2019Date of Patent: September 6, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Tianhao Lu, Junzhe Miao, Yunpeng Xu, Dan Shacham, Hong H.
