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 question of valuing the services rendered by these social networks should be analyzed and compared to other informational services given by libraries, especially in the context 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 more than 660 million members from 170 industries in more than 200 countries and territories and more than 19 million users in France. Acquired by Microsoft to counter the French social network Viadeo. Viadeo is a French professional social network online since 2004 which allows to build and aggregate its network of contacts, in order to facilitate dialogue between professionals. Like LinkedIn, it is also a tool for managing e-reputation (online reputation) or personal marketing, which attracts a greater number of types of profiles from senior and professional executives. In 2020, Viadeo claims 8 million members in France from companies and students. Both portals have the same business model through advertising, subscriptions and recruiting services. We will focus our assessment on macro-criteria as essential: - information retrieval services, personalized access services, documentation services, participatory services, networking services, and data warehouses. |
