Identifying relationships between entities using machine learning

A system comprising:

• at least one hardware processor;
• and
• a non-transitory machine-readable medium embodying a set of instructions that;
• when executed by the at least one hardware processor, cause the at least one processor to perform operations, the operations comprising:
• accessing corresponding profile data from each one of a plurality of profiles stored in a database of an online service;
• extracting a plurality of training entity pairs from the profile data of the plurality of profiles based on a matching of at least one regular expression with the profile data, each one of the plurality of training entity pairs comprising a first training entity and a second training entity;
• training at least one model using the plurality of training entity pairs as training data;
• receiving natural language text comprising a first target entity and a second target entity;
• identifying a relationship between the first target entity and the second target entity using the at least one model;
• and
• performing a function using the identified relationship between the first target entity and the second target entity based on the identifying of the relationship.

A non-transitory machine-readable medium embodying a set of instructions that, when executed by at least one hardware processor, cause the processor to perform operations, the operations comprising:

• ingesting natural language text comprising a first target entity and a second target entity;
• identifying a relationship between the first target entity and the second target entity using at least one model;
• and
• performing a function using the identified relationship between the first target entity and the second target entity based on the identifying of the relationship, the function comprising a database modification operation or a relationship verification operation, the database modification operation comprising modifying at least one of a graph, a corresponding profile of the first target entity, and a corresponding profile of the second target entity stored in the database of the online service to indicate the identified relationship, and the relationship verification operation comprising causing the identified relationship to be displayed on a computing device.
