Entity resolution techniques for matching entity records from different data sources

A method comprising:

• identifying a first entity record from a source database;
• identifying, in the first entity record, a plurality of data items, each of which corresponds to an attribute of a plurality of source attributes;
• for a first data item, of the plurality of data items, that corresponds to a first source attribute of the plurality of source attributes, identifying a plurality of target attributes;
• generating a first query that includes a plurality of predicates, each predicate corresponding to a different data item-target attribute pair and including the first data item and a different target attribute of the plurality of target attributes;
• wherein the plurality of predicates are combined with a disjunctive OR;
• performing a first search of a target database based on the first query, wherein the first search results in a first set of results;
• using a scoring model to generate a set of scores, one for each result in the first set of results;
• determining whether the first entity record matches an entity record in the target database based on the set of scores generated by the scoring model;
• generating a second query that is different than the first query;
• performing a second search of the target database based on the second query, wherein the second search results in a second set of results;
• wherein using the scoring model comprises using the scoring model to generate a score for each result in the first and second sets of results;
• wherein the method is performed by one or more computing devices.

One or more storage media storing instructions which, when executed by one or more processors, cause:

• identifying a first entity record from a source database;
• identifying, in the first entity record, a plurality of data items, each of which corresponds to an attribute of a plurality of source attributes;
• for a first data item, of the plurality of data items, that corresponds to a first source attribute of the plurality of source attributes, identifying a plurality of target attributes;
• generating a first query that includes the plurality of data items and that associates the first data item with each of the plurality of target attributes;
• generating a second query that is different than the first query;
• performing a first search of a target database based on the first query, wherein the first search results in a first set of results;
• performing a second search of the target database based on the second query, wherein the second search results in a second set of results;
• using a scoring model to generate a set of scores, one score for each result in the first and second sets of results;
• determining whether the first entity record matches an entity record in the target database based on the set of scores generated by the scoring model.
