摘要
Provided are a method and a system for determining a trend and a turning point of a stock price index using sentiment-based indexes in accordance with an analysis of social data. The method for determining a trend and a turning point of a stock price index comprises the steps of: collecting a plurality of documents related with an item group from social media data or the like during a first period to an updated date, when the renewal of a date occurs, and a second period longer than the first period and generating and storing sensitivity evaluation data about the entire documents by date; calculating a first moving average of sensitivity evaluation data by date included in the first period and generating accumulative first moving average data including a first moving average before the renewal and a first moving average after the renewal; calculating a second moving average of sensitivity evaluation data by date included in the second period and generating accumulative second moving average data including a second moving average before the renewal and a second moving average after the renewal; and determining a short-term trend in the stock price index related to the item group as a rise or a fall, when the accumulative first moving average data are greater or less than the accumulative second moving average data.
