SQE-ezed out: SRA, status and stasis

2. Robinson and Sra¤a

In this chapter I follow the evolution of Joan Robinson’s appreciation of Sra¤a’s “critique of economic theory”over the years. My purpose is twofold: …rst, to construct a narrative based also on the archival …ndings; second, to shed some light on certain dividing issues–as we shall see in the …nal section– which impinged on the fortunes of the “Cambridge school”, in search of a clue to explain ...

Repetition & Stasis

SRA Project for ARPA / USACOM

The USACOM project is part of the larger SAIC/BBN Advanced Joint Planning (AJP) Advanced Concepts Technology Demonstration (ACTD). The primary objective of the project is to demonstrate the effectiveness of Tipster-sponsored data extraction technologies. Although this project is just now getting underway, we plan to investigate the applicability of data extraction technologies in a number of sc...

SRA: description of the SRA system as used for MUC-6

INTRODUCTIO N SRA used the combination of two systems for the MUC–6 tasks : NameTag"" , a commercial software product that recognizes proper names and other key phrases in text ; and HASTEN, an experimental text extraction system that has been under development for only one year . For the Named Entity task, SRA adapted a subset of NameTag ' s capabilities to the MUC–6 specification . For the Te...

CVaR minimization by the SRA algorithm

Using the risk measure CV aR in financial analysis has become more and more popular recently. In this paper we apply CV aR for portfolio optimization. The problem is formulated as a two-stage stochastic programming model, and the SRA algorithm, a recently developed heuristic algorithm, is applied for minimizing CV aR.
