1st Workshop on User Modeling in Heterogeneous Search Environments (HetUM 2015) in conjunction with CIKM 2015
CALL FOR PAPERS
19 October 2015, Melbourne, Australia
Regular paper submission: 19 June 2015
Special track for re-submissions of CIKM papers: 8 July 2015
Notification of acceptance: 23 July 2015
Camera ready: 7 August 2015
Workshop: 19 October 2015
When users interact with information retrieval (IR) systems, they leave rich implicit feedback in the form of clicks, mouse movements, etc. This feedback contains valuable information about users and about IR systems. Analyzing and interpreting user interactions and modeling user search behavior has become an important research direction. It enables us to better understand users, perform user simulations, improve search algorithms and build quality metrics.
However, IR systems become more and more heterogeneous: they deal with information of various media types, structure and semantics; run on multiple devices and support a variety of short- and long-term search tasks; serve users with different background and preferences. Better user models are needed to support effective IR methods in such heterogeneous environments.
SCOPE AND TOPICS
The workshop brings together current initiatives, resources and experts in user modeling and heterogeneous search to build a common ground for developing better user models in heterogeneous search environments. The proposed workshop has two main themes: (1) combining advances in user modeling and heterogeneous search, and (2) building and sharing datasets that contain rich user interaction data.
The first theme incorporates studies on click models, models of mouse movement, aggregated and federated search, etc. The second theme includes research on capturing and analyzing user search interactions, such as cursor trajectories and touch gestures. It also builds on experience in anonymizing query logs, organizing privacy reviews, etc.
The topics of the workshop include, but are not limited to:
- Modeling user behavior:
- Click model construction
- Modeling search interactions beyond clicks
- Session-level user modeling
- Cross-session and cross-device user modeling
- Satisfaction prediction
- Heterogeneous search:
- Interaction with heterogeneous components on SERPs
- Heterogeneous information source selection
- Aggregated ranking of heterogeneous items
- UI and UX design for heterogeneous search
- Performance evaluation of heterogeneous search
- Search interaction data mining:
- Click-through data
- Query reformulation data
- Cursor movement data
- Eye-tracking data
- Other interaction data (e.g., purchase actions, location data, etc.)
- Practical issues:
- Acquiring sufficient amount of interaction data in academic environments
- Acquiring interaction data at scale without disturbing the users
- Conducting privacy reviews in academia and industry
- Anonymizing search interaction data and releasing it to public
- Reference/benchmark implementations for data acquisition, data analysis and user modeling
Submissions must be formatted according to the ACM SIG proceedings format (option 2) and must not exceed 4 pages. We encourage position papers and work-in-progress papers. The reviewing process is single-blind, so submissions do not need to be anonymized. At least one author of each accepted paper is required to present their work at the workshop.
Please submit your paper through the submission web site:
The deadline for regular papers is June 19. The workshop also offers a special track for authors of papers that were not successful at the main conference for their work to be considered for presentation at the workshop; the deadline for these contributions is July 8. In this case, authors are required to attach the reviews for their paper along with the paper so as to facilitate the decision process.
