Discussion question: What is information?

Definitions Data – Sets of symbols representing captured evidence of activities, transactions, and events Information – That which carries ideas; selected and manipulated data Source: Pao, Miranda Lee Concepts of information retrieval. Englewood, CO: Libraries Unlimited.

Definitions (cont’d) Knowledge – Processed information which has produced a change in the intellectual framework of learning within an individual. Not all contacts between information and individuals result in knowledge acquisition. Source: Pao, Miranda Lee Concepts of information retrieval. Englewood, CO: Libraries Unlimited.

Thought question: What is communication?

Shannon & Weaver Communication in libraries

Communication “Communication is the use of words, letters, symbols, or similar means to achieve common or shared information about an object or occurrence.” (Cherry 1978, 216)

Types of communication Reference

Communication models  Linear models  Trace a one-way flow of messages with the speaker or sender developing or encoding a message that would be sent over a channel or channels to be received by a listener or receiver

Communication models (2)  Interactional models  Take into account critical importance of feedback— signals or messages that tell the sender what is happening at the receiving end of the process

Shannon-Weaver model (cont’d) Information source produces message Transmitter operates on the message in some way to produce a signal suitable for transmission over the chosen channel

Shannon-Weaver model (cont’d) Channel is the medium used to transmit the signal from the transmitter to the receiver. It can be a beam of light, a band of radio frequency, etc.

Shannon-Weaver model (cont’d) Receiver accepts and decodes signals into information Destination is the person or thing for whom the message is intended

Informativeness The informativeness of a message is that property which reduces uncertainty in the intended recipient... In other words, information is concerned with the degree of change to the knowledge state of the recipient as compared with the original state prior to the exposure to the message.

Informativeness (2) Information is a measure of one’s freedom of choice when one selects a message.

Weaver’s 3 levels of the communication problem TechnicalAccuracyMessage SemanticPrecisionMeaning Effectiveness Intended Response Behavior LevelConcernAffects

Level one: technical Grand Jury Was the signal accurate?

Level two: semantic Grand Jury What does it mean? It depends on the meaning of "is"

Level three: effectiveness Grand Jury What did the grand jury do? ???????? ????????
