Systems and Methods for Extracting Table Information from Documents

摘要

Systems and methods for extracting table information from documents are provided herein. Exemplary methods may include annotating a document with annotations that identify table cell data included therein, generating a candidate table for each of a plurality of table models using the annotated table cell data, scoring each of the candidate tables, selecting a highest scoring candidate table, and annotating the highest scoring table to produce a final table.

1. A method, for extracting table information from an unstructured document using a table extraction system that comprises a processor and table extraction logic stored in memory, wherein the processor executes the table extraction logic to perform operations comprising:
annotating text of a document with annotations using domain knowledge of the unstructured document to produce annotated table cell data; generating a candidate table for each of a plurality of table models using the annotated table cell data; scoring each of the candidate tables; selecting a highest scoring candidate table; andproviding the highest scoring candidate table.
