Journal of the American Society for Information Science, 1979
AbstractBased on the definition of information acquisition as the reduction in uncertainty, the concept of ignorance is defined as the state of uncertainty. Two basic types of ignorance are then defined as substitutes for information: guessing and belief.

Information Systems Management, 1996
Measuring the value of the information produced by operational data processing systems and decision assistance systems is a challenging process with an attractive payoff— avoiding misallocation of funds.

Reflections on information and information value
IEEE Transactions on Systems, Man, and Cybernetics, 1995Information, as explicated by C.E. Shannon (1949), refers to the reduction in uncertainty about the state of an event after a message has been sent relative to the uncertainty about the state of the event before the message was sent. Information value, as explicated by R.A.

Values-Informed Research and Research-Informed Values
2019Abstract While social work must be evaluative in relation to its diverse areas of practice and research (i.e., values-informed research), the purpose of this chapter is to propose that values are within the scope of research and therefore research on practice should make values a legitimate object of investigation (i.e., research ...

The Value of the Value of Information
Human and Ecological Risk Assessment: An International Journal, 1999An important application of decision analysis is determining the value that information has to a decision maker. The expected value of information (EVOI) is the expected increase in the value (or decrease in the loss) associated with obtaining more information about quantities relevant to the decision process. The EVOI can be thought of as a measure of

Value of Information Lotteries
IEEE Transactions on Systems Science and Cybernetics, 1967The essence of decision-making is understanding the economic impact of uncertainty. In this paper a previous discussion of information value theory is extended to illustrate how the availability of information on the uncertain factors of a problem affects the probability density function of profit, the profit lottery.

Transportation Research Record: Journal of the Transportation Research Board, 2005
For models of the use of advanced travel information services (ATISs) and their effect on traveler behavior to be realistic from a behavioral point of view, conceptualizations of travelers’ perceptions of the value of information must be valid. This paper presents a formulation of perceived information value based on the idea that travelers face ...

Mutations and the value of information
Journal of Theoretical Biology, 1979Abstract On the basis of the literary data the relative probabilities of the point mutations are evaluated in the proteins and in RNA's. The relative probabilities of the nonsense mutations are estimated. The probability of the nonsense mutation of the codon UGG (Trp) is especially high.

On the value of temporal information in information retrieval
ACM SIGIR Forum, 2007Time is an important dimension of any information space and can be very useful in information retrieval. Current information retrieval systems and applications do not take advantage of all the time information available in the content of documents to provide better search results and user experience.
