Document analysis is the process of examining and interpreting documents to extract meaningful information. This method is often used in fields like history, law, and social sciences to understand the context, purpose, and content of written materials. Analysts look for patterns, themes, and discrepancies to gain insights into the document's significance. The analysis can involve various types of documents, such as letters, reports, and official records. Techniques may include content analysis, where specific words or phrases are counted, and discourse analysis, which focuses on the language and structure used. This systematic approach helps researchers and professionals draw conclusions based on documented evidence.
