Abstract
In a data mining system, data is gathered into a data store using, e.g., a Web crawler. The data is classified into entities. Data miners use rules to process the entities and append respective keys to the entities representing characteristics of the entities as derived from rules embodied in the miners. With these keys, characteristics of entities as defined by disparate expert authors of the data miners are identified for use in responding to complex data requests from customers.
Claims29
A system, comprising:
- at least one data store;
- at least one lower level analysis engine communicating with the data store and generating an output using a first set of rules;
- and
- at least one higher level analysis engine receiving the output of the lower level analysis engine and generating an output using a second set of rules.
A data mining system, comprising:
- a data store including data classified into entities;
- plural data miners using rules to process the entities and append respective keys to the entities representing characteristics of the entities as derived from rules embodied in the miners, whereby characteristics of entities as defined by expert authors of the data miners are identified for use in responding to data requests from customers.
A method for extracting data from a data store, comprising:
- accessing entities in the data store;
- processing the entities using at least a first set of rules to identify at least a first characteristic of the entities;
- at least for entities having the first characteristic, associating at least one representation of the characteristic with the entities;
- receiving as input to a second set of rules only entities having at least
- the first characteristic, based on the representation of the characteristic;
- and
- processing the entities having at least the first characteristic using at least the second set of rules to identify at least a second characteristic of the entities.
A computer program device readable by a processing system for data mining, comprising:
- means for accessing entities in a data store;
- means for processing the entities using at least a first set of rules to identify at least a first characteristic of the entities;
- means for associating, at least for entities having the first characteristic, at least one representation of the characteristic with the entities;
- means for receiving as input to a second set of rules only entities having at least the first characteristic, based on the representation of the characteristic;
- and
- means for processing the entities having at least the first characteristic using at least the second set of rules to identify at least a second characteristic of the entities.
