Characteristics of Tax Forms:
Tax forms are structured documents with consistent layouts and predefined fields (e.g., Name, Tax ID, Income).
Extraction Method:
Rule-Based Extraction: Ideal for structured documents like tax forms. Rules are defined based on the location and format of fields, ensuring high accuracy.
Example: Extracting "Total Tax Due" based on its known position on the form.
Option Analysis:
Option A: Screen Scraping is not recommended for structured documents; it's better for unstructured or semi-structured data.
Option B: Model-based extraction is better for variable formats, but tax forms are typically fixed.
Option D: Tax forms do not vary significantly, making this option incorrect.
Correct Option (C): Rule-based extraction is efficient and appropriate for structured formats.
