A hybrid approach for social media forensics

Social media plays a pivotal role as a rich source of data for digital forensics investigators, enabling the extraction of valuable evidence for crime analysis. This research introduces a hybrid digital forensics approach for social media investigation, compatible with all web-browsing devices. This hybrid approach combines a three-stage classification process consisting of TextBlob sentiment analysis to analyse the tweet's polarity, VADER to detect suspicious tweets, and a crime-type dictionary to categorise crime-related tweets. Using Python libraries, Twitter data is collected using authentic Twitter accounts, hashtags, or keywords, then cleaned, translated, geolocated, and classified. A real-time interactive platform is implemented for crime detection and analysis, bolstering the capabilities of law enforcement agencies and researchers in understanding crime patterns. The research concludes with promising results, highlighting the potential of the approach, and discusses future enhancements, ultimately aiding in crime analysis and prevention.
