Guiding people to information

摘要

We describe Rosetta, a digital library system for scientific literature. Rosetta makes it easy for people to find the information for which they are looking even when using short, imprecise queries. Rosetta indexes research articles based on the way they have been described when cited in other documents. The concise descriptions that occur in citations are similar to the short queries people typically form when searching; therefore, citations make a better basis for indexing than do the words used within a research article itself. Using this indexing technique we are able to provide a user interface that presents users with an automatically generated directory of the information space surrounding a query. Our objective with this interface is to present people with the information for which they have asked as well as the information for which they may have intended to ask.
