INFORMATIVENESS AND THE COMPUTATIONAL METROLOGY OF COLLABORATIVE ADAPTIVE SENSOR SYSTEMS

Language comprehenders make a wide variety of pragmatic inferences to determine the meaning of ambiguous utterances in context. These inferences are affected by both the informativeness of the alternative messages with respect to an interpretation and the relevance of potential interpretations within the context (Grice, 1975). We use simple referential games to explore the interaction of these ...

Human languages carve the world into category systems that are highly informative (e.g. Kemp & Regier, 2012)—but how do such systems develop? One possibility is that these systems result from the process of cultural transmission. Xu, Dowman, and Griffiths (2013) showed that human simulation of cultural transmission in the lab creates systems of categories that converge toward those in natural l...

People often issue informational queries to search engines to find out more about some entities or events. While a Wikipedia-like summary would be an ideal answer to such queries, not all queries have a corresponding Wikipedia entry. In this work we propose to study query-oriented keyphrase extraction, which can be used to assist search results summarization. We propose a general method for key...

We examined rates of informativeness in the production of modifications in response to a visual contrast In a video description task with speakers of Yucatec Maya. We analyzed modifications of referring expressions on the part of a speaker, and we also examined the effect of overand underinformativeness on the listener’s comprehension. We found that prior experience with difficult comprehension...

The finance industry has grown, financial markets have become more liquid, and information technology allows arbitrageurs to trade faster than ever. But have market prices then become more informative? We construct a model with information acquisition and investment to link financial development, price informativeness, and allocational efficiency. We then use market prices to construct the mode...

This article examines factors influencing consumer attitudes towards SMS advertising. The study’s research framework was conceptualized using five predictor variables – informativeness, irritation, privacy, credibility, and incentives – and an outcome variable of consumer attitudes towards SMS advertising. The informativeness, irritation, and privacy was labelled as central route constructs and...

Informativeness measures have been used in interactive information retrieval and automatic summarization evaluation. Indeed, as opposed to adhoc retrieval, these two tasks cannot rely on the Cranfield evaluation paradigm in which retrieved documents are compared to static query relevance document lists. In this paper, we explore the use of informativeness measures to evaluate adhoc task. The ad...

I study the effects of the heterogeneity of traders’ horizons in a 2-period NREE model where all traders are risk averse. Owing to risk premia, short termism generates multiple equilibria. In particular two distinct patterns arise. Along the “low trading intensity equilibrium,” short termists anticipate a thinner second period market and, owing to risk aversion, scale back their trades. This re...
