Indiana University, in partnership with eight other academic libraries, will enable new kinds of computational research while ensuring librarians remain expert stewards of information collections. In the last decade, there has been a nearly exponential increase in the volume of digital content, much of which could be valuable for computational research. However, not all datasets can be made…

Total funding to date
$49,429.00
Funding agency
Google

In order for older texts to be searchable, contemporary English needs to be translated into language from various historical timeframes. The project will develop software that will let people enter a query in contemporary English, and search over English texts throughout history—from Medieval times to the present day. The project will mostly involve training statistical models that assign…

This project aims to improve search engine effectiveness by using knowledge base (KB) entries to inform query expansion. While the intersection of KBs and information retrieval (IR) is a growing research area, this project proposes a novel approach to KB-based query modeling. In particular, this project proposes to let the structure that KB authors impose within individual KB entries guide the…

Time affects information retrieval in many ways. Collections of documents change as new items are indexed. The content of documents themselves may change. Users submit queries at particular moments in time. And perhaps most importantly, people’s assessment of a document’s relevance to a query is often time-dependent. For example, searchers of news archives might seek information on a past…
