We invite you to participate in the 26th International Conference on Collaboration Technologies and Social Computing (CollabTech 2020).

The conference is a major forum for both academics and practitioners to exchange their experiences related to the development and use of collaboration technology, and it has a strong focus on technology design and development. Most published papers propose innovative technical + human + organizational approaches to expand collaboration support, often backed up by theory brought from various disciplines including computer science, management science, design science, cognitive science, and social science. However, the conference also seeks papers with theory, models, design principles, methodologies, and case studies that contribute to a better understanding of the complex interrelations between collaboration and technology. Considering the heterogeneity of research in collaboration and technology, researchers may address the validation of their work through multiple approaches including laboratory experiments, fieldwork, analytical evaluations, case studies, prototyping, and empirical tests.
This year, the conference will be hosted by the University of Tartu and we look forward to welcoming you all in Estonia!

*** Submission Guidelines ***
Electronic paper submissions should be prepared using the Springer Proceedings format (https://www.springer.com/gp/computer-science/lncs/conference-proceedings-guidelines). Submissions will be accepted in three categories: full papers, short papers and poster abstracts. Full papers have a length of up to 16 pages, short papers have a length of up to 8 pages and poster abstracts have a maximum length of 4 pages (including references). Doctoral consortium papers have a length of 7 pages and should present the work of the phD students in their area. Full papers present original results on a subject of interest to the CollabTech community while short papers can present smaller more focused contributions or preliminary results which inspire discussion. Full papers and short papers appear in the proceedings, while poster abstracts are made available electronically. Accepted full papers and short papers will be published by Springer as part of their Lecture Notes in Computer Science (LNCS) series. (www.springer.com/lncs).

*** Journal Special Issue ***
The authors of the best papers presented at the conference will be cordially invited to submit extended versions to a journal special issue.


***COVID-19 UPDATE***
We are continuously monitoring the recent developments regarding coronavirus (COVID-19) and we will consider all possible scenarios with respect to the conference and traveling. As it is still too early to make a final decision, we continue with preparations for the conference as planned.
However, in the unfortunate event that a face-to-face meeting is not possible, we will be prepared to seamlessly transition to an online solution. All accepted papers will be included in the conference proceedings no matter the circumstances.
We will provide more details as they become available.
