Towards Search Standardisation

Towards Search Standardisation

The EU-funded COST Network IC1002 (http://www.mumia-network.eu/ ) is a four year (2010-2014) networking programme which aims to promote collaboration between researchers and professionals working on Multilingual and Multifaceted Information Access (MUMIA), principally in Information Retrieval, Machine Translation and related topics. More than 250 scientists and professionals from 28 COST countries and 4 non COST countries […]

Information Wayfinding, Pt 2: Elements of the Information Environment

Information Wayfinding, Pt 2: Elements of the Information Environment

In Part 1 of this series, I argued that vestiges of the pre-Web, print era still haunt digital experiences. To create information environments that are truly coherent, we must view them not as books full of pages, but as spaces to navigate and explore—much like finding our way through a city or a museum. This is […]

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 […]

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 […]

Information Retrieval between Disciplines: Computer Science and Information Science – The IR group at the University of Hildesheim

Information Retrieval Research in Germany is mainly done within the Computer Science Community represented by the Special Interest Group. But there is also a considerable amount of work done within the smaller Information Science Community in the German speaking countries. The University of Hildesheim forms a link between these otherwise largely distinct communities. Information Science […]

Kayak.com’s mobile website—with four rows of controls and a large advertisement—clearly fails to adequately prioritize its search results.

Design Principles for Mobile Search

Apple’s iOS Human Interface Guidelines and Google’s Android Design Guidelines both provide valuable guidance for designing general mobile applications. But there are a number of design principles that can help us achieve effective mobile search experiences in particular. Namely, most mobile search applications should prioritize content over controls, provide answers over results, and ensure cross-channel continuity.

A matrix of mobile information needs.

The Information Needs of Mobile Searchers

We live in a post-desktop era. In the UK alone, 45% of Internet users used a mobile phone to connect to the Internet in 2011 [7], and Morgan Stanley predicts that by 2014 there will be more mobile Internet users than desktop Internet users globally [6]. Not only are more people connecting with mobile devices, […]
