This paper describes a natural language system START. The system analyzes English text and automatically transforms it into an appropriate representation, the knowledge base, which incorporates the information found in the text. The user gains access to information stored in…

The Listener is an automated system that unintrusively performs knowledge acquisition from informal input. The Listener develops a coherent internal representation of a description from an initial set of disorganized, imprecise, incomplete, ambiguous, and possibly inconsistent statements. The Listener can…

The so-called diversity-multiplexing tradeoff characterizes the fundamental interaction between the robustness and capacity gains obtainable from multiple-input and
multiple-output (MIMO) systems in fading environments. This thesis develops practical schemes for approaching the optimal tradeoff in various delay and complexity
regimes.…

Corporate household (CHH) refers to the organizational information about the structure within the corporation and
a variety of inter-organizational relationships. Knowledge derived from this data is becoming increasingly important
for improving data quality in applications, such as Customer…

I have invented "Internet Fish," a novel class of resource-discovery tools designed to help users extract useful information from the Internet. Internet Fish (IFish) are semi-autonomous, persistent information brokers; users deploy individual IFish to gather and refine information related to…

Electrical circuit designers seldom create really new topologies or use old ones in a novel way. Most designs are known combinations of common configurations tailored for the particular problem at hand. In this thesis I show that much of the…

Most studies on Japanese supplier-automaker relationships have focused on the nature of
the dyadic inter-firm relationship and the performance of the assembler. We examine the
relationship between a Japanese supplier's "customer scope strategy" (i.e. number of
customers) and the supplier's…

A series-parallel directed acyclic graph, or SP-dag, contains nodes that are either in series or logically in parallel. We present a data structure and algorithm to efficiently determine, in a single serial walk of the dag, whether two nodes are…

Public authorities and private developers around the world are attempting to create and sustain hubs within the innovation-based economy by fostering successful urban environments. These large-scale developments succeed an earlier generation of post-industrial "technopoles" named after the French word popularized…
