The ACM Transactions on Interactive Intelligent Systems

(Latest update: Monday, September 21st, 2015)

TiiS (pronounced “T double-eye S”) is an ACM journal for research about intelligent systems that people interact with.

The journal publishes articles on research concerning the design, realization, or evaluation of interactive systems that incorporate some form of machine intelligence.

TiiS articles come from a wide range of research areas and communities. An article can take any of several complementary views of interactive intelligent systems, focusing on ...

  • the intelligent technology,
  • the interaction of users with the system, or
  • both aspects at once.


On September 18th, at the 2015 ACM Conference on Recommender Systems (RecSys) in Vienna, the following cooperation agreement between the RecSys conference series and ACM TiiS was announced:

  • A RecSys 2015 author whose paper contains a substantial interaction component can submit an extended version to a special TiiS issue “Highlights of RecSys 2015” (special issue associate editor: Jennifer Goldbek, program cochair of RecSys 2015). This arrangement is to be repeated in future years.
  • A TiiS author of an article of relevance to the RecSys community can present it at the next RecSys conference.

Details on procedures and dates will be provided directly to the authors in question.  

Current and Upcoming Issues

The most recent complete issue of ACM TiiS, 5(2), comprises the first 5 articles from the two-part special issue on Behavior Understanding for Arts and Entertainment.

The next issue, 5(3), which will be appearing incrementally in the Digital Library, comprises the last 2 articles of the special issue on Behavior Understanding for Arts and Entertainment plus 3 regular articles.
