Abstract
An information extraction system and methods of operating the system are provided. In particular, an information extraction system for performing meta-extraction of named entities of people, organizations, and locations as well as relationships and events from text documents are described herein.
Claims26
An information extraction system comprising:
- a master device, configured to receive input data and experimental options;
- an extractor device, configured to transform input data into extractor output;
- an aggregator device, configured to aggregate extracted entities of the extractor output to form meta-entities, dispatch meta-entities to aggregation algorithms, form hypotheses for each meta-entity, calculate probability for each hypothesis, and reconstruct a truth entity based on each hypothesis;
- a storage device, configured to store input data, extractor output, and other files;
- and
- a communication device, configured to enable high bandwidth communication of data between the devices of the information extraction system.

An information extraction system, comprising:
- a master module for receiving input data and experimental options;
- an extractor module, coupled to the master module, for transforming input data into extractor output;
- and
- an aggregator module, coupled to the extractor module, for aggregating extracted entities of the extractor output to form meta-entities, dispatching meta-entities to aggregation algorithms, forming hypotheses for each meta-entity, calculating probability for each hypothesis, and reconstructing a truth entity based on each hypothesis.
