Editorial
Welcome back! This spring 2013 edition of Informer will bring you a range of fairly different articles, perhaps just the right mix for this time of the year. More about the articles later, let us first have a glimpse at what has been going on in the IR community. SIGIR 2013 is taking shape. Following the […]
Information Wayfinding, Part 1: A Not-So-New Metaphor
Browsing the Web. Surfing the Net. Navigating a Web site. Traversing a hierarchy. Going back. Scrolling up and down. Returning home. We’ve seen such metaphors throughout our history of using computers to interact with information. Haphazard though they may seem be, these metaphors highlight a universal reality of human psychology: we perceive the world—both physical […]
Call for Book Reviews (Spring 2013)
This issue we include another Call for Reviews in which we seek reviewers for a number of recently published books that may be of interest to the IR community. Books will be allocated for review on a first-come-first-served basis and you would have about one month to carry out the review. If you are interested […]
Interaction Models for Faceted Search
Introduction Faceted search offers tremendous potential for transforming the search experience. It provides a flexible framework by which users can satisfy a wide variety of information needs, ranging from simple fact retrieval to complex exploratory search and discovery scenarios. But there is one design aspect of faceted search that is particuarly hard to get right: […]
Search: Emergent and Extrinsic Semantics
Semantics is a term often used in the search technology and information retrieval community these days. A distinction is drawn between semantic and traditional search, implying that somehow semantic search is a more advanced or sophisticated form. My claim in this article is that there are actually two forms of semantic search: emergent and extrinsic. […]
Hybrid Parallel Classifiers for Managing Big Data with Hierarchies
“Big Data” is one of the latest buzzwords in the IT industry nowadays. Companies are building up huge stores of data running into terabytes and more. Data hierarchies are getting bigger and bigger and more complex. At the same time, search/categorization speeds are also expected to increase. Single classifiers are now unable to deal with […]

Made in Germany – Information Retrieval Research in Regensburg
These are heady times for the German IR community. Norbert Fuhr’s recent winning of the Salton Prize not only rewarded a fantastic and long-term individual contribution to the field, but has also served to shed light on the whole IR scene in Germany – a fact underlined by this “Made in Germany” series. There are […]
