We describe a purely confidence-based geographic term disambiguation system that crucially relies on the notion of "positive" and "negative" context and methods for combining confidence-based disambiguation with measures of relevance to a user's query.

Abstract. Many geographic terms, such as “river ” and “lake”, are vague, with no clear boundaries of application. In particular, the spatial extent of such features is often vaguely carved out of a continuously varying observable domain. We present a means of defining vague terms using standpoint

Today's wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited

to determine the characteristics of the spread of Code-Red throughout the Internet. In this paper, we describe the methodology we use to trace the spread of Code-Red, and then describe the results of our trace analyses. We first detail the spread of the Code-Red and CodeRedII worms in terms of infection

Abstract: The present-day identity of San Antonio, Texas, is closely linked to its Hispanic heritage. This identity is not solely a result of the dominant ethnic Mexican population but in large measure is a constructed identity conceived, assembled, and promoted by non-Hispanic patrons of the community. This identity, though rooted in the city's Hispanic past, is manifested in two romanticized Spanish landscapes, the Paseo del Rio and La Villita. This essay examines the character of the ideal landscape-making process in this Texas Mexican city. [ABSTRACT FROM AUTHOR]

ABSTRACT The aim of this study was to analyze the 2001 Excite query log to investigate the extent and variation of Web queries containing geographic terms. In particular, an investigation into what people search for when they use geographic terms, the ways in which they describe a geographic

. First, it can be implemented in a decentralized way provided some local geographic information is available to the mobiles. In addition, its transport capacity is proportional to the square root of the density of mobiles which is the upper bound of Gupta and Kumar. Finally, this protocol is self

forcing at the TOA and the larger negative forcing at the surface. We can not resort to observed rainfall trends to infer the net anthropogenic effect on global rainfall as long-term rainfall measurements are only available for land regions. Regional climate effects We have just begun to comprehend

What explains differences in firms' abilities to acquire competitive capabilities? In this paper we propose that embeddedness, in terms of firms' network of bridging ties and linkages to regional institutions, are important sources of variation in firms' acquisition of competitive
