General Course Information

On this web page, information for the seminar 'Hot Topics in Information Retrieval', which is held during the Summer Term 2011 by Farag Ahmed, Tatiana Gossen and Andreas Nürnberger, is provided.

Alle Informationen auf dieser Webseite sind auf Englisch angegeben, um auch englischsprachigen Studierenden die Teilnahme am Seminar zu ermöglichen. Vorträge und Ausarbeitungen können sowohl in Englisch als auch in Deutsch gehalten bzw. erstellt werden.

Description of topics

This seminar is devoted to emerging trends in Information Retrieval like Cross-language IR, Children IR, Personalized IR and Opinion mining.

Cross-language IR (CLIR)

The increasing diversity of the Internet web sites has created millions of multilingual resources in the world wide web. Cross-language IR deals with retrieving information written in a language different from the language of the user's query. For example, users may write their queries in German but retrieve relevant documents written in French. Following topics are available:

Children IR

The Internet today is widely used by children to search for new information and communicate. Unfortunately, most of the existing Information Retrieval (IR) solutions are designed for adults who have shown to have different search behavior and cognitive skills than children. Thus, the research on children information retrieval in terms of both user interfaces and underlying algorithms is very important. Following topics are available:

Personalized IR

Current information retrieval systems return the same retrieval results to all users for identical queries, regardless of varied user interests and information needs. Personalized IR provides information for each user based on his/her interests .i.e., for a specific given query, personalized IR can provide different retrieval results for different users. Furthermore, personalized IR organizes retrieval results differently based on the user's interests, preferences, and information needs. Following topics are available:

 Opinion mining

An important part of our information-seeking behavior is to find out what other people think about specific topic. Opinion mining (OM) is a recent discipline at the crossroads of information retrieval and computational linguistics which is concerned not with the topic a document is about, but with the opinion it expresses. Opinion mining is used to identify and extract subjective information in source materials. Due to the abundance of opinion-rich resources that reside in online review sites, personal blogs etc. new challenges arise in how to use information technologies in order to search and understand the opinions of others. Following topics are available:
