System and method for entity disambiguation for customer relationship management

1. A system for disambiguating attributes associated with one or more entities, the system comprising:

an entity disambiguation computer comprising a memory, a processor, and a plurality of programming instructions, the plurality of programming instructions when executed by the processor cause the processor to:

receive electronic information associated with a candidate entity among the one or more entities in an entity database at pre-defined intervals, wherein the received electronic information comprises multiple versions of data associated with the one or more entities received from one or more external data sources over a network;

extract and store at the entity database, one or more attributes associated with the candidate entity from the electronic information;

for each of the one or more attributes, call and run software functions to:

create and store a set of timeslice objects, wherein the set of timeslice objects are associated with respective durations;

select and store a subset of timeslice objects from the set timeslice objects for candidate comparison based on an overlap between durations in respective timeslice objects;

predict whether the subset of timeslice objects corresponds to a same entity by comparing the overlapping durations in the subset of timeslice objects using a machine-learning similarity model comprising weight and biases assigned to sets of previously used overlapping durations to:

compute, for each attribute, distance vectors between the subset of timeslice objects, wherein a vectorizer converts the overlapping durations to distance vectors;

predict if the subset of timeslice objects represented by distance vectors correspond to the same entity by comparing the distance vectors with a similarity model comprising weight and biases assigned to sets of previous distance vectors;

responsive to predicting that the subset of timeslice objects correspond to the same entity, combine the subset of timeslice objects by merging the selected timeslice objects into a single entity identity record, and

store the prediction; and

responsive to determining, based on the prediction, that the subset of timeslice objects correspond to the same entity, store and merge the subset of timeslice objects to generate an unambiguous entity database.

2. The system of claim 1 , wherein the one or more attributes comprises a location, a geocode, an entity name, a stock symbol, a registered entity identity, an entity classification code, an entity uniform resource links (URLs), employee data, an entity event, a technology domain, an entity group connection, an entity brand, and a competitor.

3. The system of claim 2 , wherein to extract the one or more attributes, the plurality of instructions when executed by the processor, further cause the processor to:

tokenize the electronic information;

responsive to identifying that the electronic information has multiple components based on one or more tokens:

determine that the one or more attributes in the electronic information are related to an entity name based on the multiple components; and disambiguate and classify the multiple components into at least a base name, a connector, a function and/or industry, and a legal identifier associated with the entity name.

4. The system of claim 3 , wherein to extract the one or more attributes, the plurality of instructions when executed by the processor, further cause the processor to:

responsive to identifying that a first attribute, of the one or more attributes, is a location:

disambiguate and compare the one or more tokens associated with the location with a plurality of known locations;

responsive to determining that there is a match between the one or more tokens associated with the location and a first known location of the plurality of locations, assign a geocode to the location.

5. The system of claim 3 , wherein the plurality of instructions when executed by the processor, further cause the processor to:

responsive to determining that the one or more tokens are related to the employee data, disambiguate and classify employee attributes from the one or more tokens, wherein the employee attribute comprises an employee skill, an employee job title, a location of employee, a gender, and an educational qualifications.

6. The system of claim 3 , wherein the disambiguation and classification of the multiple components of an entity name is performed using at least one of fingerprinting, semantic embedding or a conditional random fields (CRF) classifier model.

7. A method for disambiguating attributes associated with one or more entities, the method comprising:

receiving, at an entity disambiguation computer, from one or more external data sources over a network, electronic information associated with a candidate entity among the one or more entities in an entity database at pre-defined intervals, wherein the received electronic information comprises multiple versions of the one or more entities;

extracting and storing at the entity database, by the entity disambiguation computer one or more attributes associated with the candidate entity from the electronic information;

for each of the one or more attributes, call and run software functions for:

creating and storing a set of timeslice objects, wherein the set of timeslice objects are associated with respective durations;

selecting and storing a subset of timeslice objects from the set timeslice objects for candidate comparison based on an overlap between durations in respective timeslice objects;

predicting whether the subset of timeslice objects corresponds to a same entity by comparing the overlapping durations in the subset of timeslice objects using a machine learning similarity model comprising weight and biases assigned to sets of previously used overlapping durations by:

computing, for each attribute, distance vectors between selected set of timeslice objects, wherein a vectorizer converts the overlapping durations to distance vectors;

predicting if the selected timeslice objects represented by distance vectors correspond to the same entity by comparing the distance vectors with a similarity model comprising weight and biases assigned to sets of previous distance vectors;

responsive to predicting that the selected timeslice objects correspond to the same entity, merging the selected timeslice objects into a single entity identity record; and generating an unambiguous entity database by merging of the subset of timeslice objects, and

storing the prediction; and

responsive to determining that the subset of timeslice objects correspond to the same entity, based on the prediction, storing and merging the subset of timeslice objects to generate an unambiguous entity database.

8. The method of claim 7 , wherein the one or more attributes comprises a location, a geocode, an entity name, a stock symbol, a registered entity identity, an entity classification code, an entity uniform resource links (URLs), employee data, an entity event, a technology domain, an entity group connection, an entity brand, and a competitor.

9. The method of claim 8 , wherein extracting the one or more attributes further comprises the steps of:

tokenizing the information;

responsive to identifying that information has multiple components based on one or more tokens:

determining that attribute in the received information is related to an entity name based on the multiple components; and

disambiguating and classifying the multiple components into at least a base name, a connector, a function and/or industry, and a legal identifier associated with the entity name.

10. The method of claim 9 , wherein extracting the one or more attributes further comprises the steps of:

responsive to identifying that a first attribute, of the one or more attributes, is a location:

disambiguating and comparing one or more tokens associated with the location with a plurality of known locations;

responsive to determining that there is match between the one or more tokens associated with the location and a first known location of the plurality of locations, assigning a geocode to the location.

11. The method of claim 10 , wherein extracting the one or more attributes further comprises the steps of:

responsive to determining that the one or more tokens are related to the employee data, disambiguating and classifying employee attributes from the one or more tokens, wherein the employee attribute comprises an employee skill, an employee job title, a location of employee, a gender, and an educational qualification.

12. The method of claim 9 , wherein the disambiguation and classification of the multiple components of an entity name is performed using at least one of fingerprinting, semantic embedding or a conditional random fields (CRF) classifier model.
