The　widespread　adoption　of　social　media　platforms　has　led　to　an　influx　of　data　that　reflects　public　sentiment,　presenting　a　novel　opportunity　for　market　analysis.　This　research　aims　to　quantify　the　correlation　between　the　fleeting　sentiments　expressed　on　social　media　and　the　measurable　fluctuations　in　the　stock　market.　By　adapting　a　pre-existing　sentiment　analysis　algorithm,　we　refined　a　model　specifically　for　evaluating　the　sentiment　of　tweets　associated　with　financial　markets.　The　model　was　trained　and　validated　against　a　comprehensive　dataset　of　stock-related　discussions　on　Twitter,　allowing　for　the　identification　of　subtle　emotional　cues　that　may　predict　changes　in　stock　prices.　Our　quantitative　approach　and　methodical　testing　have　revealed　a　statistically　significant　relationship　between　sentiment　expressed　on　Twitter　and　subsequent　stock　market　activity.　These　findings　suggest　that　machine　learning　algorithms　can　be　instrumental　in　enhancing　the　analytical　capabilities　of　financial　experts.　This　article　details　the　technical　methodologies　used,　the　obstacles　overcome,　and　the　potential　benefits　of　integrating　machine　learning-based　sentiment　analysis　into　the　realm　of　economic　forecasting.　©　Copyright　2024　Guo　and　Xie
