Computer-implemented systems and methods for comparing and associating objects

A method for associating objects within one or more groups of objects within a plurality of objects, each object comprising a first plurality of properties, each property comprising data reflecting a characteristic of an entity represented by the object, the associated objects within a group of objects comprising matching data in corresponding properties for a second plurality of properties that includes at least some of the first plurality of properties, the method comprising the following operations performed by one or more processors:

• executing, for each object within the plurality of objects, the following:
• creating a slug for the object, the slug comprising the second plurality of properties from the object;
• and
• inputting the slug for the object into a counting Bloom filter;
• inputting for each created slug, the slug and its corresponding object into a multimap, if a bin within the counting Bloom filter corresponding to the slug has a count value greater than 1, wherein the slug is a key to the multimap and the object is a value to the multimap;
• and
• associating the objects stored as values for each multimap key with two or more corresponding values.

A system for associating a first object with one or more objects within a plurality of objects, each object comprising a first plurality of properties, each property comprising data reflecting a characteristic of an entity represented by the object, the associated objects comprising matching data in corresponding properties for a second plurality of properties that includes at least some of the first plurality of properties, the system comprising:

• a memory device that stores a set of instructions;
• and
• at least one processor that executes the set of instructions to perform the following operations:
• executing, for each object within the plurality of objects and for the first object, the following:
• creating a slug for the object, the slug comprising the second plurality of properties from the object;
• and
• inputting the slug for the object into a Bloom filter;
• and
• creating for a bin within the Bloom filter corresponding to the slug for the first object, an association between objects whose slugs correspond to the bin if the slugs for those objects match.
