Source linking and subsequent recall

A method, system, and computer program product are provided. During creating a document by a creation module, the content of the document is analyzed. Sources used while creating the document are analyzed using NLP, sentiment analysis, tone analysis, speech-to-text, and visual recognition. The sources are associated with a location in the document. Sources are filtered out based on a degree of correlation to the document. Sources are linked to the document where a correlation is found between the document and the sources. The linked sources are stored in a database for recall. During a presentation of the document, upon receiving a question, the question is analyzed to determine a relevant logical section of the document, and the relevant sources are retrieved.
