Full papers: High quality, original research of relevance to CHIIR may be submitted as a full paper (8 pages + max 2 pages references). Submissions should include an analysis or evaluation using rigorous techniques such as laboratory studies, field experiments, in situ observational studies, crowdsourcing, simulations of search behavior, or log analysis. Authors should describe their methods, specific techniques, and search context in sufficient detail to allow for replication and reuse. Accepted full papers will be published in the proceedings, and presented as paper presentations at the conference.

Perspective papers: A special category of full papers (8 pages + max 2 pages references), perspective papers should present novel ideas or insights concerning approaches, key challenges, or theoretical or methodological issues that have the potential to inspire substantive discussion and lead to significant advances in the field. These papers should not consist primarily of literature reviews or the presentation of stand-alone studies, but may take the form of:

• Reflections upon the body of research, considering how the field, the theories, the models, and the methods have developed;
• Discussion of the implications of research findings on users in the real world;
• Proposals for and discussions of theories or models of information-interaction; or Critical, provocative, and creative contributions to stir debate and discussion.

Short papers: Short papers (4 pages + max 1 page references) should report on original, significant, high-quality research. A short paper could present a more focused study of smaller scope than a full paper. For example, work in progress, preliminary research analysis, or late-breaking results are suitable for short papers. Accepted short papers will be published in the proceedings, and presented as posters at the conference.

Demonstrations and Resources: We welcome two types of submissions (both are 4 pages + max 1 page references).

• Demonstration papers should enable presenters to give participants first-hand experience of novel research prototypes, operational systems, or in-progress concepts in development. The submission should both describe and show the proposed solution, addressing questions such as: What problem does the prototype/system/concept seek to address? How does it do so? Who are the users? How will you demonstrate this work? How does the work compare with those that exist already? Finally, how, where and when will your technology have a technical or commercial impact?
• Resource papers should describe publicly available datasets or open source softwares that are new or not well-known, allowing researchers to replicate research results and providing a citable paper when using that resource. Resource papers will be evaluated based on the quality of the resource, its novelty compared to other available alternatives, how well it has been described, and its potential for investigating a variety of research questions.

The authors should submit a short video of the demo in addition to the paper describing the work. The authors are also encouraged (but not required) to include a URL where the demo itself can be accessed. For submissions of datasets, authors should provide a public URL for downloading. For submissions of softwares, the source code, dependencies on external libraries, and installation instructions must be available on a public Web page or in a publicly accessible repository. All datasets and source code must be licensed in such a manner that it can be legally and freely used, at the minimum in academic and research settings.

Wireless network access, along with a table and poster mount backdrop, will be provided for all accepted demonstrations and resources. A paper describing each accepted demonstration will be included in the conference proceedings.

Doctoral Consortium: Doctoral Consortium proposals (4 pages including references) should include the abstract, motivation, research questions, (planned or ongoing) methodology, progress made, and future plans. The CHIIR Doctoral Consortium, held in conjunction with the main conference, provides an opportunity for doctoral students to present and discuss their research with senior researchers and other doctoral students in a seminar format. The Doctoral Consortium focuses on 1) advising students regarding current critical issues in their research, and 2) making students aware of the strengths and weaknesses of their research as viewed from different perspectives. Accepted proposals are eligible for publication in the proceedings. Doctoral consortium submissions are not anonymous.

Workshops: Original workshop proposals (4 pages including references) should be highly interactive and could be either full-day or half-day. We welcome workshops that address important issues, discuss potential solutions, integrate various approaches, and offer innovative perspectives within the themes of the conference and have strong potential to contribute to the evolution of research and development of human computer interaction and information retrieval. Workshop proposals are not anonymous.

Tutorials: Proposals for tutorials (4 pages including references) should address topics relevant to the themes of the conference and could be either full-day or half-day. Each proposal is expected to cover the selected topic in depth by providing the audience with different perspectives, approaches, and recent developments and advances in the community. Tutorial proposals are not anonymous.

Accepted workshops and tutorials will be included in the conference proceedings.

AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date affects the deadline for any patent filings related to published work. (For those rare conferences whose proceedings are published in the ACM Digital Library after the conference is over, the official publication date remains the first day of the conference.)
