#Workshop Theme:
Over 60% of the online population are non-English speakers and it is
probable the number of non-English speakers is growing faster than
English speakers. Recent studies showed that non-English queries and
unclassifiable queries have nearly tripled since 1997. Most search
engines were originally engineered for English. They do not take full
account of inflectional semantics nor, for example, diacritics or the
use of capitals.
The main conclusion from the literature is that searching using
non-English and non-Latin based queries results in lower success and
requires additional user effort so as to achieve acceptable recall and
precision. Further international search engines (like Yahoo and Google)
are relatively weaker with monolingual non-English queries.
New tools and resources are needed to support researchers in non-English
retrieval. New methodologies need to be proposed which will help the
identification of problems in existing search engines. New teaching
strategies should be formed aiding users to become more efficient in
formulating their queries.

#Aims and Topics:

The main objectives of the workshop are to propose techniques and to
evaluate tools which improve the effectiveness of the existing search
engines. The specific aims of the workshop are:
* Evaluate search engines in non-English queries and measure the
additional user effort.
* Define methodologies for evaluating the effectiveness of search
engines in non-English queries.
* Study the user query patterns in non-English Web retrieval.
* Identify the factors that influence utilization of search engines in a
multicultural world.
* Propose extensions to the search engines to improve non-English Web
* Propose teaching strategies for helping users improve their searching
* Identify how standard IR techniques (Indexing, Query representation,
Query reformulation, etc) can be adapted in Web retrieval for
non-English languages.
* Discuss the application of natural language processing techniques for
non-English Web IR.

# Workshop areas of interest include, but are not limited to:

* Evaluation methodologies
* Analysis of query logs
* Localization of search engine interfaces
* Performance issues of local search engines
* User studies
* Image and video retrieval services
* Summarization
* Teaching

#Invited speaker: To be announced

Journal publication:
Authors of best papers will be invited to submit extended versions of
their papers to a special issue of an international journal.
