*The 7th International Workshop on Online Social Networks Technologies (OSNT 2021) * *http://emergingtechnet.org/OSNT2021/ <http://emergingtechnet.org/OSNT2021/>* *In conjunction with **The Eighth International Conference on Social Networks Analysis, Management and Security (SNAMS-2021)* <http://emergingtechnet.org/SNAMS2021/index.php> *Gandia, Spain. December 6-9, 2021* *OSNT 2021 CFP* The explosion of the Internet helps the social networking concept to become real, and to be a tool to connect people worldwide in ways that were previously impossible. The Internet’s first generation (Web 1.0) consisted of static pages instead of dynamic HTML, and the presented content to the user is served from a server's file system instead of a Relational Database Management System (RDBMS). The second generation (Web 2.0) encouraged users to share information and interact and collaborate with each other by posting their user-generated contents in virtual communities. The development of Web 2.0 allowed many new social networking sites to flourish such as Facebook, Twitter, LinkedIn, Pinterest, Google Plus+, Tumblr, Instagram, VK, Flickr, Vine, and many others. Such Online Social Networks (OSN) provide a wealth of raw data that is invaluable to governments, companies, universities, etc. The large scale of such networks presents a challenge to providers just to keep them running smoothly. It also presents a challenge to researchers wanting to analyze the data collected from such networks. These challenges contributed to the rise of important of important fields such as big data. The objective of this workshop is to provide general guidelines on the current and future trends in online social network technologies. Authors are encouraged to submit their original work, which is not submitted elsewhere, to this workshop. Proceedings of the workshops will be published by the IEEE Conference Publishing Services (CPS) and will be submitted for inclusion in the IEEE-Xplore and the IEEE Computer Society (CSDL) digital libraries. Authors are encouraged to submit their original work, which is not submitted elsewhere, to this workshop. The topics of the workshop include but not limited to: * Social network analysis (SNA) * Online Social Networks Mining * Security in Online Social Networks * Architecture and growth of Online Social Networks * Social networks visualization and large scale data representation * Online Social Networks and Big Data * Online Social Networks and SNA tools and services on the Cloud * Location-based OSN and other geographical aspects of OSN * Society Impact of Online Social Networks * Community formation, analysis and detection in Online Social Networks * Anomaly detection in Online Social Networks evolution * Recommender systems and Online Social Networks * Emerging technologies in Big Data and Social Networking * Management Issues of Social Network Big Data * Security challenges in Big Data and Social networks * Social Network and Big Data Analytics * Network Infrastructure for Social Networking and Big Data * Social Networks Monitoring Tools as a Service * Cloud Computing for Big Data and Social Networks * Social network data analysis tools and services on the Cloud * Case studies *Submissions Guidelines and Proceedings* Manuscripts should be prepared in 10-point font using the IEEE 8.5" x 11" two-column format (IEEE Templates <https://www.ieee.org/conferences_events/conferences/publishing/templates.html>). All papers should be in PDF format, and submitted electronically at Paper Submission Link. A full paper must not exceed the stated length (including all figures, tables and references). Submitted papers must present original unpublished research that is not currently under review for any other conference or journal. Papers not following these guidelines may be rejected without review. Also submissions received after the due date, exceeding length limit, or not appropriately structured may also not be considered. Authors may contact the Program Chair for further information or clarification. All submissions are peer-reviewed by at least three reviewers. Accepted papers will appear in the SNAMS Proceeding and to be submitted to IEEE Xplore for inclusion. The proceedings are also submitted for indexing to EI (Compendex), Scopus and other indexing services like DBLP. Submitted papers must include original work, and must not be under consideration for another conference or journal. Submission of regular papers must not exceed 8 pages and must follow the IEEE paper format. Please include up to 7 keywords, complete postal and e-mail address, and fax and phone numbers of the corresponding author. Authors of accepted papers are expected to present their work at the conference. Submitted papers that are deemed of good quality but that could not be accepted as regular papers will be accepted as short papers. Length of short papers *Important Dates* Submission Date: 5 Oct, 2021 Notification to Authors: 21 Oct, 2021 Camera Ready Submission: 30th Oct, 2021 *Journal Special Issues* Selected papers from the presented papers will be invited to submit an extended version to number of journals. Papers will be selected based on their reviewers’ scores and appropriateness to the Journal’s theme. All extended versions will undergo reviews and must represent original unpublished research work. Further details will be made available at a later stage. Please send any inquiry to the Emerging Tech. Network Team at: emergingtechnetwork@gmail.com
