One of the many changes that have occurred in the field of journalism over the last years is the involvement of citizens in news production, a development which has challenged some of the traditional values of journalism and led to the emergence of new concepts, such as crowdsourcing. Crowdsourcing is a process of obtaining information and services from many organizations or individuals. The notion of crowdsourcing includes crowdcreation (or user- generated content) and crowdfunding (asking the crowd to provide funding). This study adds to the existing literature of crowdsourcing, crowdcreation and crowdfunding by focusing closely on Greek and Cypriot news websites and by examining how these websites use crowdsourcing features. The findings demonstrate that the majority of the news websites in Greece and Cyprus do not include crowdsourcing features (crowdfunding and crowdcreation) on their websites.
Though accurate information and news are crucial for all modern democratic societies, fake news and misinformation seem to be present even in mainstream traditional media. Journalists used to be the gatekeepers of news providing reliable information to audiences mainly through the dominant traditional media. Nevertheless, this has significantly changed. The emergence of digital journalism, social media, participatory journalism, and a significant decline in trin public sphere control and agenda-setting. Citizens of the digital era have plenty of opportunities not only to access information such as news but also to record, produce, comment, share or criticize such information. Without a doubt, social media and citizen journalism have been heavily criticized for helping fake news, hoaxes, and non-true stories to spread in the public sphere but this is not the case. Fake news and most importantly misinformation and disinformation seem to derive not only from social media but surprisingly from established traditional media outlets who are supposed to be the main gatekeepers of truth and news reliability. This paper scopes to reveal how crowdsourcing techniques such as crowd wisdom, crowd voting, and crowd creation mainly through social media have overturned cases of misinformation and fake news presented in traditional and established media outlets during the covid-19 pandemic lock-down in Greece. The walkthrough method and statistical analysis are used in order to track the cases of fake news and misinformatireveal the importance of crowdsourcing and its different techniques as a tool for digital journalism in the battle against fake news and misinformation, shaping new communication models.
Fake news and misinformation are a menace to the public sphere, democracy, and societywith sometimes irreversible consequences. Journalists in the new era seem not to be able or willingto play their traditional role of gatekeeper and social media have made the problem even moreintense. The need for truth is unnegotiable in modern democracies. Nevertheless, non-true storiesand misinformation dominate media outlets with severe consequences and negative impacts onsocieties all over the world. Fact-checking platforms based on crowdsourcing strategies or automateddigital websites might be the answer to a problem that is escalating. Initially, in order to tackle sucha severe problem, researchers and experts have to monitor its characteristics. Very few researchattempts have been conducted in Greece on fake news, its characteristics, origin, and impact. Thisdissertation scopes to map the characteristics of fake news and misinformation in an EU countrysuch as Greece, based on the findings of “Ellinika Hoaxes” a fact-checking platform that uses incombination professional fact-checkers and crowdsourcing strategies in collaboration with Facebook.The findings shape new perspectives on the nature of misinformation and fake news in Greece andfocus on new communication and fact-checking models.
Traditionally journalism is a key function for democracy. News used to be produced by professional journalists and the term "gatekeeper", used to describe a journalist's main task, filtering information, and when and how reliable news should be provided. However, users can now choose to get the information they want from many online sources, websites most of which are free and social media. Citizens of the digital era have plenty of opportunities not only to access information such as news, but also to produce, share or criticize such information, whose credibility is not always confirmed. This led to the beginning of the participatory journalism era where crowdsourcing techniques such as crowdwisdom (commenting on news media websites articles or on social media pages) play a significant role in the public sphere. However, crowdsourcing, social media sources and citizen journalism is often criticized as a key fake news generator while traditional journalism outlets seem more credible. This paper studies the fake news phenomenon in Greece using the walk-though method and statistical analysis for the 500 most popular Greek news websites exploring the confirmed cases of fake news revealed by the Facebook certified fact-checking website “Ellinika Hoaxes”. The findings of the study chart Greek media landscape characteristics and reveal new perspectives for traditional journalism, crowdsourcing and news distribution outlets credibility.
