This paper describes a means for linking Ž eld and object representations of geographical space. The approach is based on a series of mappings, where locations in a continuous Ž eld are mapped to discrete objects. An object in this context is a modeler’s conceptualization, as in a viewshed, highway corridor or biological reserve. An object can be represented as a point, line, polygon, network, ...

Entity resolution is the task of identifying all mentions that represent the same real-world entity within a knowledge base or across multiple knowledge bases. We address the problem of performing entity resolution on RDF graphs containing multiple types of nodes, using the links between instances of different types to improve the accuracy. For example, in a graph of products and manufacturers ...

Theories of inter-organisational co-ordination propose that information processing capabilities (structure, process and technology) must be aligned with information processing needs (environmental, partnership and task uncertainty) and the fit between both is a strong determinant of performance. Electronic marketplaces dominate new developments in electronic commerce. While traditional models p...

Group communication implies a many-to-many communication and it goes beyond both one-to-one communication (i.e., unicast) and one-to-many communication (i.e., multicast). Unlike most user authentication protocols that authenticate a single user each time, we propose a new type of authentication, called group authentication, that authenticates all users in a group at once. The group authenticati...

Development is fundamentally about understanding people, their Motivations, behaviors and reactions. We have two primary means of understanding people— observing what they do, and what they say. As the AI4D community has noted, people’s increased use of mobile devices has led to a wealth of new data relevant to these topics. We are on the cusp of developing incredibly powerful tools that can he...
