Dynamic topic models

by David M. Blei, John D. Lafferty - In ICML , 2006
"... Scientists need new tools to explore and browse large collections of scholarly literature. Thanks to organizations such as JSTOR, which scan and index the original bound archives of many journals, modern scientists can search digital libraries spanning hundreds of years. A scientist, suddenly ..."

An extension of the Hirsch index: Indexing scientific topics and compounds

by Michael G. Banks, Michael G. Banks - Scientometrics , 2006
"... An interesting twist of the Hirsch index is given, in terms of an index for topics and compounds. By comparing both the hb index and m for a number of compounds and topics, it can be used to differentiate between a new so-called hot topic with older topics. This quick method is shown to help new com ..."

RESEARCH ARTICLE Content Volatility of Scientific Topics in Wikipedia

by A Cautionary Tale, Adamm. Wilson, Gene E. Likens
"... Wikipedia has quickly become one of the most frequently accessed encyclopedic refer-ences, despite the ease with which content can be changed and the potential for ‘edit wars’ surrounding controversial topics. Little is known about how this potential for controversy affects the accuracy and stabilit ..."

Here we present an analysis of the Wikipedia edit histories for seven scientific articles and show that topics we consider politically but not scientifically “controversial ” (such as evolution and global

The Data Grid: Towards an Architecture for the Distributed Management and Analysis of Large Scientific Datasets

by Ann Chervenak , Ian Foster, Carl Kesselman, Charles Salisbury, Steven Tuecke - JOURNAL OF NETWORK AND COMPUTER APPLICATIONS , 1999

Bayes Factors

by Robert E. Kass, Adrian E. Raftery , 1995
"... In a 1935 paper, and in his book Theory of Probability, Jeffreys developed a methodology for quantifying the evidence in favor of a scientific theory. The centerpiece was a number, now called the Bayes factor, which is the posterior odds of the null hypothesis when the prior probability on the null ..."

Models and issues in data stream systems

by Brian Babcock, Shivnath Babu, Mayur Datar, Rajeev Motwani, Jennifer Widom - IN PODS , 2002
"... In this overview paper we motivate the need for and research issues arising from a new model of data processing. In this model, data does not take the form of persistent relations, but rather arrives in multiple, continuous, rapid, time-varying data streams. In addition to reviewing past work releva ..."
Abstract - Cited by 770 (19 self) - Add to MetaCart
relevant to data stream systems and current projects in the area, the paper explores topics in stream query languages, new requirements and challenges in query processing, and algorithmic issues.

The Simple Economics of Basic Scientific Research

I begin this essay by reflecting on my early paper (Nelson, 1859), and Ken’s (Arrow, 1962), as period pieces. These papers certainly have been influential in shaping the discussion of science and technology policy over the last forty years, at least among economists, but at the time they were written, economists were just beginning to get into analysis of the key processes and institutions involved in technological advance. A lot has been learned since that time, and the discussion has become much more sophisticated. I will highlight two of those intellectual developments: the growing recognition that technological advance must be understood as an evolutionary process, and recognition that the institutions involved in that process include much more than the simple market institutions on which economists usually focus. Then I turn to the contemporary policy arena that is the focus of this conference: issues relating to intellectual property. Both to link the discussion to my old paper, and because my own recent research has been focused there, I shall focus particularly on the patenting of “science”. Finally, I will consider the institutional division of labor in research and development, and argue that the question of what should be private and what should be public about science and technology cannot be explored adequately without explicit consideration of mechanisms of funding, and of who is expected to do the work under what terms. I will focus particularly on the role of universities in the system of institutions that do R and D. 2
