Paper of LiNCS researchers accepted to JASIST

Web search engines are the gateway for users to access health information. This study explored whether a search interface based on the Bing API and enabled by Scatter/Gather, a well-known document clustering technique, can improve health information search. Forty participants without medical background were randomly assigned to two interfaces, a baseline interface that resembles typical Web search engines and a Scatter/Gather interface. Both groups performed two lookup and two exploratory health-related tasks.

With the ubiquitous production, distribution and consumption of information, today’s digital envi- ronments such as the Web are becoming increasingly large and decentralized. It is hardly possible to obtain central control over information collections and systems in these environments. Search- ing for information in these information spaces has brought about problems beyond traditional boundaries of information retrieval (IR) research.

Weimao Ke publishes in the Scientometrics journal

We propose a model to analyze citation growth and influences of fitness (competitiveness) factors in an evolving citation network. Applying the proposed method to modeling citations to papers and scholars in the InfoVis 2004 data, a benchmark collection about a 31-year history of information visualization, leads to findings consistent with citation distributions in general and observations of the domain in particular. Fitness variables based on prior impacts and the time factor have significant influences on citation outcomes.

Hybrid Scatter/Gather browsing based on Bing search API

Another Scatter/Gather implementation for searching + browsing based on Bing search API:

Scatter/Gather browser on a news collection

We implemented a Scatter/Gather browser using 33k news documents provided by HARD track from the Text REtrieval Conference (TREC). Scatter/Gather provides a different approach (from classic paradigms of searching and browsing) to finding information and is often useful in situations where the user may feel difficult to formulate a search query.
