*TIR'09 - 6th International Workshop on Text-Based Information Retrieval*
---------------------------------------------------------------------------

In conjunction with the DEXA 2009
20th International Conference on Database and Expert Systems Applications

Linz, Austria, August 31 - September 4

About this Workshop:
---------------------------------------------------------------------------

Intelligent algorithms for mining and retrieval are the key technology to
cope with the information need challenges in our media-centered
society. Methods for text-based information retrieval receive special
attention, which results from the important role of written text, from the
high availability of the Internet, and from the enormous importance of Web
communities.

Advanced information retrieval and extraction uses methods from different
areas: machine learning, computer linguistics and psychology, user
interaction and modeling, information visualization, Web engineering,
artificial intelligence, or distributed systems. The development of
intelligent retrieval tools requires the understanding and combination of
the achievements in these areas, and in this sense the workshop provides a
common platform for presenting and discussing new solutions.

The following list organizes classic and ongoing topics from the field of
text-based IR for which contributions are welcome:

* Theory. Retrieval models, language models, similarity measures, formal analysis

* Mining and Classification. Category formation, clustering, entity resolution, document classification, learning methods for ranking

* Web. Community mining, social network analysis, structured retrieval from XML documents

* NLP. Text summarization, keyword extraction, topic identification

* User Interface. Paradigms and algorithms for information visualization, personalization, privacy issue

* User Context. Context models for IR, context analysis from user behaviour and from social networks

* Multilinguality. Cross-language retrieval, multilingual retrieval, machine translation for IR

* Evaluation. Corpus construction, experiment design, conception of user studies

* Semantic Web. Meta data analysis and tagging, knowledge extraction, inference, and maintenance

* Software Engineering. Frameworks and architectures for retrieval technology, distributed IR

The workshop is held for the sixth time. In the past, it was characterized
by a stimulating atmosphere, and it attracted high quality contributions
from all over the world. In particular, we encourage participants to
present research prototypes and demonstration tools of their research
ideas.
