Doctoral Symposium of CISTI'2020 - 15th Iberian Conference on Information 
Systems and Technologies
   Sevilla, Spain, 24 - 27 June 
2020
   
http://www.cisti.eu/ 


 

The purpose of CISTI'2020’s Doctoral Symposium is to provide graduate students 
a setting where they can, informally, expose and discuss their work, collecting 
valuable expert opinions and sharing new ideas, methods and applications. The 
Doctoral Symposium is an excellent opportunity for PhD students to present and 
discuss their work in a Workshop format. Each presentation will be evaluated by 
a panel composed by at least three Information Systems and Technologies experts.

 

Contributions Submission

The Doctoral Symposium is opened to PhD students whose research area includes 
the themes proposed for this Conference. Submissions must include an extended 
abstract (maximum 4 pages), following the Conference style guide 
. All selected contributions will be 
published with the Conference Proceedings in electronic format with ISBN. These 
contributions will be available in the IEEE Xplore 
 Digital Library 
and will be sent for indexing in ISI, Scopus, EI-Compendex, INSPEC and Google 
Scholar.

Submissions must include the field, the PhD institution and the number of 
months devoted to the development of the work. Additionally, they should 
include in a clear and succinct manner:

•The problem approached and its significance or relevance
•The research objectives and related investigation topics
•A brief display of what is already known
•A proposed solution methodology for the problem
•Expected results

 

Important Dates

Paper submission: February 14, 2020

Notification of acceptance: March 22, 2020

Submission of accepted papers: April 5, 2020

Payment of registration, to ensure the inclusion of an accepted paper in the 
conference proceedings: April 5, 2020
