Recent advances in natural language processing and text mining using machine learning now enable systematically mining such corpora to discover hidden patterns and actionable knowledge:
Topic modeling algorithms can rapidly parse thousands of agricultural documents to extract frequently discussed concepts and trends. This allows aggregating knowledge on specific issues like pest management or irrigation practices.
Text classifiers developed on labeled text can categorize agricultural documents into domains like crop science, horticulture, animal husbandry, etc. This enables filtering sources by relevance.
Entity recognition techniques can identify key objects like crop varieties, fertilizers, pests, etc., and their relationships in unstructured text. This automates knowledge graph construction.
Sentiment analysis of the text can discern farmer reactions and opinions on agricultural technologies and policies guiding R&D.
Summarization algorithms can distill lengthy reports into concise insights farmers can readily absorb.
Overall, text mining using machine learning, combined with knowledge engineering, helps unlock the knowledge trapped in agricultural literature to augment farmer skills.
