EVALUATION OF THE USE OF PROFESSIONAL SOCIAL NETWORKS: COMPARISON OF INFORMATION SERVICES AND RECOMMENDATION SYSTEMS OF LINKEDIN AND VIADEO

Summary/Abstract: The use of social media has grown rapidly in recent years, but analytical work is still dominated by the motivations of members to join social media. However, we believe that the issue of valuing the services provided by these social networks should be analyzed and compared to other information services offered by libraries, especially within the framework of professional networking sites (for example, LinkedIn, Viadeo). Future avenues of research and the implications of the framework developed are discussed, highlighting the strengths and weaknesses of these professional networking sites. LinkedIn (https://fr.linkedin.com/ ) and Viadeo (https://viadeo.journaldunet.com/ ) are based on the same principle, they are professional social networks intended to create an essentially professional network. LinkedIn claims over 660 million members from 170 industries in over 200 countries and territories and over 19 million users in France. LinkedIn is acquired by Microsoft to counter the French social network Viadeo. Viadeo is a French professional social network online since 2004 which allows building and aggregating its network of contacts, in order to facilitate dialogue between professionals. Like LinkedIn, it is also an e-reputation (online reputation) or personal marketing management tool, which attracts a greater number of types of senior and professional profiles. In 2020, Viadeo claims 8 million members in France among companies and students. Both portals have the same business model across advertising, subscriptions and recruiting services. We will focus our assessment on macro criteria as essential: - ergonomics services, information retrieval services, personalized access services, documentation services, participatory services, networking services
