The 9th ACM International Conference on Web Search and Data Mining

San Francisco, California, USA. February 22-25, 2016.

Call for Papers

Submission Website:

  • Abstract submission deadline is 10 July, 2015.
  • Final paper submissions are due 17 July, 2015.

WSDM (pronounced "wisdom") is one of the premier conferences on web inspired research involving search and data mining. The Ninth ACM International WSDM Conference will take place in San Francisco, California, USA during 22-25 February 2016.

WSDM is a highly selective, single track meeting that includes invited talks as well as refereed full papers.
WSDM publishes original, high-quality papers related to search and data mining on the Web and the Social Web, with an emphasis on practical yet principled novel models of search and data mining, algorithm design and analysis, economic implications, and in-depth experimental analysis of accuracy and performance.

Papers emphasizing novel algorithmic approaches are particularly encouraged. Application-oriented papers that make innovative technical contributions to research are welcome. Visionary papers on new and emerging topics are also welcome.

Topics covered include but are not limited to:

Web Search

  • Web dynamics and search
  • Multifaceted and task-driven search
  • Multimedia Web search

Authors are explicitly discouraged from submitting papers that do not clearly present their contribution with respect to previous works, that contain only incremental results, and that do not provide significant advances over existing approaches.

Submissions must represent new and original work. Concurrent submissions are not allowed. Papers that have been published in or accepted to any peer-reviewed journal or conference/workshop with published proceedings, are currently under review, or will be submitted to other meetings or publications while under review for WSDM 2016 may not be submitted to WSDM 2016. Submissions that have been previously presented in venues with no formal proceedings or as posters are allowed, but must be so indicated on the first page of the submission. Additionally, the ACM has a strict policy against plagiarism and self-plagiarism. All prior work must be appropriately cited.

Paper Format

Papers must be formatted according to ACM guidelines and style files to fit within 10 pages, including references, diagrams, and appendices if any. A submitted paper must be self-contained and in English.

It is the authors' responsibility to ensure that their submissions adhere strictly to the required format as described in this call for papers. Submissions that do not conform to these guidelines may be rejected without review.


Papers must be submitted in PDF format to the EasyChair website at PDF files must have all non-standard fonts embedded. After upload, please check the copy stored on the site. Submissions that do not view or print properly may be rejected without a chance to rectify the problem. Please contact for any questions on the submission or review process.

Review Process

The review process will be single-blind, therefore author names and affiliations should be listed. Each paper will be reviewed by at least three PC members and a senior PC member. The acceptance decisions will take into account paper novelty, technical depth, elegance, practical or theoretic impact, and presentation.


The algorithms, resources and methods used within a paper should be described as rigorously as possible. If the authors feel that this cannot be done sufficiently due to the paper length limit, they are encouraged to provide links to supplementary material, including detailed descriptions, tests datasets and/or code elsewhere (e.g., code repositories, institutional websites, or the authors' website).

Reviewers may not necessarily consider the supplementary material in their reviews. But for accepted papers, we will work with the publisher to archive the supplementary material along with the camera-ready version of the paper.

Wherever appropriate, the authors are encouraged to use publicly available test collections and state-of-the-art baselines. Regardless of the types of resources used (public test collections, proprietary data, etc.), please consider sharing your intermediate/final experimental results and code with the research community, or providing alternative means of accessing your data or code if sharing is not possible. Facilitating access to these resources is an effective way to enhance the reproducibility of your methods and results, and hence the impact of your research.

Publication and Presentation

All accepted papers will be published in the ACM Digital Library. For every paper there must be a registered author to present it in person at WSDM 2016. At the conference, all the papers will be allocated a slot at the interactive poster session to encourage discussion. Additionally, selected papers will be presented during the plenary oral sessions as either long or short talks.

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.

Key Dates

  • Paper abstracts due: 10 July, 2015
  • Papers due: 17 July, 2015
  • Paper notifications: 14 October, 2015
  • Conference: 22-25 February, 2016

All deadlines are 11:59pm, anywhere in the world (Alofi time).
