Large cities and their citizens, infrastructure and sensor networks generate a great amount of data. Such data, mostly unstructured and unlinked, is useless if there is no meaning and or any kind of relationship with other datasets. 
Heterogeneous data, from different sources may work together to provide useful information for decision making, especially in critical information systems, promoting safety and protection for people, patrimony and a whole environment. 
The Workshop on Trends on Critical Information Systems for Smart Cities expects the submission of works related to: emergency management applications; social media and demographic data analysis; urban criminal trends; threat prediction based on data analysis.

We invite authors to submit unpublished work resulted from research that present original scientific result, methodological aspects, concepts and approaches in the field of ICT on Auditing. Submitted work must not be not under revision elsewhere. The submissions will be double-blind reviewed on a rolling basis to ensure a rapid decision. Therefore, authors should not include on submissions names and affiliations during the reviewing phase and avoid references in the text that can possibly identify authors. Submissions must be of Full Paper (up to 6 pages). Papers must be written in one of the official conference languages (English, Spanish or Portuguese) and must follow the conference format guidelines. 

Regardless of the type of submission, Programme Committee and Organizing Committee may suggest papers to be accepted as full-paper (6 pages), short-paper (4 pages) or poster (2 pages). Workshops full papers will be published in the conference proceedings in specific Workshop chapters. Proceedings will be submitted for indexation by ISI Thomson, SCOPUS, INSPEC and Google Scholar.
