Abstract
Methods and systems are provided to extract information within complex documents, and the extracted information may be compared to identify differences between complex documents or the extracted information may be analyzed with respect to the individual document. Information is extracted from complex documents comprising unstructured data to create a structured data repository, or analytics knowledge base. This database may be utilized to compare concepts that are common to one or more documents, allowing ease of comparison of documents, and identification of information that is different or identification of (same or similar) information that is presented differently in a set of complex documents.
