IEEEXplore Indexing
ICTS 2017 is technically co-sponsored by IEEE, therefore we have opportunity to include your submitted paper to be indexed by IEEEXplore. However, to ensure the quality of the paper, the committee will select papers that suitable for indexing. We define papers that are not suitable for indexing are papers that:
– not presented or presented by someone who is not in the paper’s author list,
– have poor written English.

Scopus Indexing

According to IEEE Publication Policies, IEEE assures wide distribution of conference proceedings by providing abstracting and indexing of all individual conference papers for inclusion in worldwide databases (e.g. Scopus). The CPP makes every reasonable attempt to ensure that abstracts and index entries of content accepted into the program are included in databases provided by independent abstracting and indexing (A&I) services. Each A&I partner makes its own editorial decision on what content it will index. IEEE cannot guarantee entries are included in any particular database.

In three consecutive years, our previous conferences (ICTS 2014, ICTS 2015, and ICTS 2016) have been indexed by Scopus. You can check author profiles that listed as author in ICTS 2014, 2015 and 2016. You are also able to find that published paper in ICTS 2014, ICTS 2015 and ICTS 2016 are listed there.
