Plot of a query-specific burst

Adaptive Temporal Query Modeling

We present an approach to query modeling that uses the temporal distribution of documents in an initially retrieved set of documents. Such distributions tend to exhibit bursts, especially in news related document collections. We hypothesize that documents in those bursts are more likely to be relevant than others. Predicated on this, we expand queries with the most distinguishing terms in high quality documents sampled from bursts. We show how the most commonly used decay function for recent document retrieval can be used as probabilistic model for temporal retrieval in general. The effectiveness of our models is demonstrated on both news collections and a collection of blog posts.

Online Religious Studies

Data transitions have revolutionized many scientific disciplines, starting with the exact sciences, then the life sciences, and now the social sciences and humanities are in the process of making the transition to becoming data intensive sciences, with descriptions through quantitative measurements. New analysis tools, and publicly accessible utterances, opinions, transactions and interactions resulting from widespread Internet and social media usage facilitate new, data-intensive research methods in disciplines that have so far relied on small-scale literature and/or panel-based studies. To illustrate the new possibilities, we report on a pilot carried out by a cross-disciplinary team consisting of computer scientists and researchers in religious studies. In the latter area, research is often focused on mapping out the convictions, hopes, and beliefs of groups of people, be it within certain religions or within any other group, such as those defined by a political party.

In the pilot, religious scholars examined the core keywords in a left-wing political party in order to determine their hopes and beliefs. Rather than following their standard way-of-working, they were equipped with a search engine with an index of content crawled from discussion forums, the party’s web site plus a range of online publications relating to the party and going back to 1990. In this paper we focus on lessons learned and on methodological innovations for religious scholars as well as for computer scientists building the enabling technology.
