A bstr act: Question answering systems have proven to be helpful to users because they can provide succinct answers that do not require users to wade through a large number of documents. However, despite recent advances in the underlying question answering technology, the problem of designing effective interfaces has been largely unexplored. We conducted a(More)
We posit that a semistructured data model offers the right balance of rich structure and flexible (or lack of) schema allowing naive end users to record information in whatever form makes it easy for them to manage. We describe our Haystack system, which exposes the richness and flexibility of the data model while offering the user natural, traditional(More)
A bstr act: A s the amount of information stored on and accessed by computer has increased over the past twenty years, the tools available for organizing and retrieving such information have become outdated. T he folder paradigm has dominated existing user interfaces as the primary mechanism for organizing information for day-today use. T his paradigm(More)
Despite recent advances in natural language question an-swering technology, the problem of designing effective user interfaces has been largely unexplored. We conducted a user study to investigate the problem and discovered that overall, users prefer a paragraph-sized chunk of text over just an exact phrase as the answer to their questions. Fur-thermore,(More)
Although a lot of information has become readily accessible and necessary for daily work, the current infrastructure for managing information is ill-suited for information-oriented activities: information and functionality is scattered across applications and websites, making it difficult to aggregate and reuse just the right set of content and operations(More)
1. OVERVIEW Since its inception, the Internet has been a hotbed of several successful communications channels, starting off with e-mail, IRC and newsgroups and more recently adding web annotation, instant messaging (IM), and news feeds. Although these channels were developed fairly independently, in many cases their respective functionalities and uses have(More)
Since its inception, the Internet has been a hotbed of successful communications channels, starting off with e-mail, Internet Relay Chat and Usenet newsgroups and more recently adding weblogs, instant messaging, and news feeds. These systems have been developed quite independently over the past half century and continue to be extended with new functionality(More)

Information based tasks rely on software applications that allow users to interact with information in some pre-defined manner deemed appropriate by the application developer or information/content provider. Whereas such an approach facilitates one way of working with the information, it does not (and cannot) take into account the unique needs of the user,(More)
