Social Security's Five OASI Inflation Indexing Problems

Problems with Tachyon Inflation

We consider cosmological consequences of string theory tachyon condensation. We show that it is very difficult to obtain inflation in the simplest versions of this theory. Typically, inflation in these theories could occur only at super-Planckian densities, where the effective 4D field theory is inapplicable. Reheating and creation of matter in models where the minimum of the tachyon potential ...

Fresh inflation from five-dimensional vacuum state

I study fresh inflation from a five-dimensional vacuum state, where the fifth dimension is constant. In this framework, the universe can be seen as inflating in a four-dimensional Friedmann-Robertson-Walker metric embedding in a five-dimensional metric. Finally, the experimental data ns = 1 (BOOMERANG-98 and MAXIMA-1, taken together COBE DMR), are consistent with p+ρt ρt ≃ 1/3 in the fresh infl...

Indexing Social Semantic Data

Social Tagging/indexing

This document is meant to be a starting point for discussion during the workshop. Actual workshop targets will be decided on during the first part of the session. It is intended to be a true workshop, so participants will be asked to actively approach the subject and work together on the final results and presentation. However, nobody will be assumed to be an a priori specialist on the topic, a...

Indexing Stories as Social Advice

This paper reports on an indexing system supporting retrieval of past cases as advice about everyday social problems; it has been implemented in the Abby lovelorn advising system. Two points are emphasized: (1) ’ d in ices are descriptions of problems and their causes, couched in a vocabulary centered on intentional causality, and (2) indices fit a fixed format that allows reification of identi...
