Twitter Data Analytics (SpringerBriefs in Computer Science)

By Shamanth Kumar, Fred Morstatter, Huan Liu

This short offers tools for harnessing Twitter facts to find strategies to complicated inquiries. The short introduces the method of amassing facts via Twitter’s APIs and provides suggestions for curating huge datasets. The textual content provides examples of Twitter facts with real-world examples, the current demanding situations and complexities of creating visible analytic instruments, and the easiest concepts to handle those concerns. Examples reveal how robust measures should be computed utilizing a number of Twitter information resources. because of its openness in sharing information, Twitter is a main instance of social media within which researchers can be certain their hypotheses, and practitioners can mine attention-grabbing styles and construct their very own purposes. This short is designed to supply researchers, practitioners, venture managers, in addition to graduate scholars with an access aspect to leap begin their Twitter endeavors. It additionally serves as a handy reference for readers professional in Twitter facts research.
