Important Dates
* 20th February, 2011: Papers due

* 18th April, 2011: DDR-2011 Workshop, Dublin, Ireland

Topic

When an ambiguous query is received, a sensible approach is for the information retrieval (IR) system to diversify the results retrieved for this query, in the hope that at least one of the interpretations of the query intent will satisfy the user. Diversity is an increasingly important topic, of interest to both academic researchers (such as participants in the TREC Web and Blog track diversity tasks), as well as to search engines professionals. In this workshop, we solicit submissions both on approaches and models for diversity, the evaluation of diverse search results, and on applications and presentation of diverse search results.

Themes

As diversity is, in general, am emerging topic, these is no consensus on various aspects of the topic. The primary aim of this workshop is to foster an interactive, in-depth environment with papers and attendees representing and discussing one of four workshop themes:

* Modelling - e.g. "What are the key components of
diversification models?"
* Evaluation - e.g. "How can a better evaluation experiment for diversification be structured?"
* Applications - e.g. "What are the key applications for diversity in commercial search?"
* Presentation - e.g. "How should diverse results be presented?"

Technical original research papers (8 pages LNCS) and position papers (5 pages LNCS) on each of these four topics are invited for submission on or before 20th February 2011.

Potential topics include (but are not limited to):
Modelling:
* Implicit diversification approaches
* Explicit diversification approaches
* Query log mining for diversity
* Learning-to-rank for diversification
* Clustering of results for diversification
* Query intent understanding
* Query type classification
Evaluation:
* Test collections for diversity
* Evaluating of diverse search results
* Measuring the ambiguity of queries
* Measuring query aspects importance
Applications:
* Product & review diversification
* Opinion and sentiment diversification
* Summarisation
* Legal precedents & patents
* Diverse recommender systems
* Diversifying in real-time & news search
* Diversification in other verticals (image/video search etc.)
Presentation:
* Presentation of diverse search results
* Clustering of diverse search results
* User studies on interfaces for diversity
* Explorative or faceted interfaces for diversity
* Diversity within aggregated/universal search


Submission Instructions

Submissions should report new (unpublished) research results, or ongoing research. Both technical paper submissions (upto 8 pages including references) and position papers (upto 5 pages including references) will be orally presented. All paper submissions must be written in English following the LNCS author guidelines. Submissions should not be anonymised.
