概要：
The Web as a global information system has revolutionized everyday
life. As one of the most disruptive technologies of the last decades,
the Web was responsible for drastic technological, economical, and
even social developments: today it forms the main source of
information as well as entertainment anytime, anywhere. It connects
people via social platforms, but is also the most influential
infrastructure for commerce and business. To facilitate this, the
tight integration of information retrieval technology and innovative
data management techniques was necessary. Since then, the Web has
prospered, diversified and developed into the largest and omnipresent
information source and, what is more, a meaningful knowledge space.

However, the basic interaction and navigation methods addressing
text-based content on the Web as well as in the underlying databases
and information systems have been progressing comparatively
slowly. Even modern systems mostly rely on techniques for retrieving,
finding, and navigating information that were developed decades
ago. Techniques like e.g. SQL queries, hierarchical categorization,
list browsing, keyword-based filtering, or simple IR-style keyword
searches are still predominant as sole method of accessing content or
services. Given the semantics behind and the connections between data
items on the Web, there is however a wide variety of applicable
methods for improving and personalizing access paradigms. Focused
information extraction working hand in hand with domain-centered
conceptual models for representation is already beginning to change
query processing.

This talk focuses on such alternative approaches for user-centered
information access going beyond categories and keywords. It introduces
querying with concepts based on individual user perceptions or
sentiments, using crowd-sourcing for query processing, or employing
analogical reasoning for the intuitive communication of information
needs.
