Detecting Crowdturfing in Social Media


Astroturfing; Malicious crowdsourcing


Astroturfing is the campaign that masks its supporters and sponsors to make it appear to be launched by grassroots participants.


Crowdsourcing is the process of obtaining needed services, ideas, or content by soliciting contributions from a group of people. Internet services facilitate the process by connecting customers and crowdsourcing workers.

Ground truth:

Ground truth is the accurate annotation of data examples, which is used in statistical models to prove or disprove research hypotheses.

Heterogeneous data:

Heterogeneous data are the data involving multiple modalities, such as a social media post containing texts and video clips.

Information diffusion:

Information diffusion happens between individuals when a flow of information travels from one individual to another.

Misinformation and disinformation:

Misinformation and disinformation are the inaccurate or false information. While disinformation is...
