Theory of Mind

by

1. Introduction. ‘

Theory of Mind’ refers to the cognitive capacity to attribute mental states to self and others. Other names for the same capacity include “commonsense psychology,” “naïve psychology,” “folk psychology,” “mind reading” and “mentalizing.” Mental attributions are commonly made in both verbal and non-verbal forms. Virtually all language communities, it seems, have words or phrases to describe mental states, including perceptions, bodily feelings, emotional states, and propositional attitudes (beliefs, desires, hopes, and intentions). People engaged in social life have many thoughts and beliefs about others’ (and their own) mental states, even when they don’t verbalize them.

Learning Threshold Parameters for Event Classification in Broadcast News

by

Abstract

In this paper we present two methods for automatic threshold parameter estimation for an event tracking algorithm. We view the threshold as a statistic of the incoming data stream, which is assumed to contain broadcast news stories from radio, television, and newswire sources. Query bias defined in terms of threshold estimators can be identified when a word co-occurrence representation for text is used. Our results suggest that both approaches learn bias from training corpora, leading to improved classification accuracy for event tracking applications. 1 Introduction The following work describes two automatic threshold selection algorithms for the event tracking problem. This problem was defined by the Topic Detection and Tracking (TDT) research initiative, a DARPA-sponsored effort comprising research groups from several commercial and academic sites. Event tracking is a form of supervised learning in which a system formulates a classifier for broadcast news using a few relevant stori...

Bus Rapid Transit Identity: An Overview of Current “Branding” Practice

by

Abstract

The emergence of new bus rapid transit (BRT) systems in recent years has prompted transit agencies across North America to establish new and unique identity programs that communicate various benefits of improved bus service. These identities and brands, however, rely largely on perception and emotional reaction, which are diff icult to quantify. This lack of “hard data” makes the efficacy of identity systems and expenditures on them difficult to assess. This evaluation of 22 BRT identity programs examines the typical constructs used to establish BRT identity: visual identifiers, nominal identifiers, and color palette.

Libel and Privacy

New York law has been extended by another case disallowing a cause of action for defamation arising from a fictional work.' In Springer v. Viking Press, the court held there was no cause of action for defamation. The case concerned plaintiff Lisa Springer and defendant Robert Tine who met while attending Columbia University and developed a close personal relationship.' While working on a novel, defendant informed plaintiff he had patterned the relationship between the hero and heroine on their own.
