Method for extracting, interpreting and standardizing tabular data from unstructured documents

摘要

A system, method, and computer program for automatically identifying, parsing, and interpreting tabular data from unstructured documents stored in various formats such as ASCII text, Unicode text, HTML, PDF text, and PDF image format is provided. A set of table identification, parsing/tokenizing, and interpreting/mapping rules are developed with grammar descriptors. These rules are then applied to a set of documents to identify a table, parse the content of the table, and interpret the parsed content, if required, thereby standardizing the tabular data.
