A Document Information Extraction Task is an information extraction task that is a document analysis task that processes document sets to extract structured information from unstructured content.
- AKA: Information Extraction (IE) from Documents Task, IE from Documents Task.
- Context:
- Task Input: Document Sets containing document items such as pdf documents, word documents, html documents, and scanned images.
- Task Output: Structured Data in formats such as json format, xml format, database records, or csv format.
- Task Performance Measure: Extraction Accuracy, Extraction Completeness, Extraction Speed, and Extraction F1-Score.

- It can be solved by IE from Documents Systems that implement IE from documents algorithms.
- It can typically extract Document Elements including text fields, table data, metadata, and embedded objects.
- It can typically handle Document Complexity from single-page documents to multi-page documents.
- It can typically apply Extraction Methods such as pattern matching, natural language processing, or machine learning.
- It can typically validate Extraction Results through schema validation or business rules.
- It can typically process Document Batches for large-scale extraction.
- ...
- It can often require Document Preprocessing such as ocr processing or format conversion.
- It can often support Incremental Extraction for document updates.
- It can often provide Extraction Confidence Scores for quality assessment.
- It can often enable Custom Field Extraction for domain-specific requirements.

- It can range from being a Simple Document Extraction Task to being a Complex Document Extraction Task, depending on its extraction requirement complexity.
- It can range from being a Manual Document Extraction Task to being an Automated Document Extraction Task, depending on its automation level.
- It can range from being an IE from Simple Documents to being an IE from Multimedia Documents, depending on its document content complexity.
- It can range from being an IE from Image Documents to being an IE from Document Metadata, depending on its document extraction target type.
- ...
- It can be performed by Document Extraction Systems through systematic processing.
- It can be solved by IE from Documents Systems implementing IE from documents algorithms.
- It can be implemented by Document Extraction Agents using extraction algorithms.
- It can utilize Schema-Based Document Extraction for structured approach.
- It can be served by Document Extraction Servers through network interfaces.

- Document Extraction Task Domains, such as:
- Counter-Example(s):
- Information Retrieval, which finds relevant documents rather than extracting structured data from them.
- Document Classification Task, which categorizes documents rather than extracting structured data.
- Document Summarization Task, which creates summarys rather than extracting specific fields.
- Document Translation Task, which converts languages rather than extracting information.
