Information transfer

Information & knowledge are created from the application of new techniques, new insights, &/or new research to existing bodies of information & knowledge

Models

• Representation of structure

OED

• Simplification of reality

• Diagnostic tool

Information transfer models highlight the stages where information needs to considered in order to get optimum advantages from it (& minimum negative results from its mismanagement)

Information transfer models

The roles of information transfer models, include:

• Understanding information transfer within different groups

• Aids to designing systems for information flow

• Diagnosing sources of information flow failure

Shannon – Weaver communication model

The Shannon-Weaver communication model was initially developed in 1947 to improve telephone line transmission. It has been refined in the succeeding decades

It is an influential model that can be applied to all forms of communication

Shannon – Weaver communication model

Within the Shannon-Weaver model we refer to noise & filters. They may be:

• Physical, eg poor technology, reception, competing noise etc

• Semantic – refers to problems of meaning, understanding etc

Science

11

Semantic noise

Semantic noise can be a sender and/or receiver problem.

It can be caused by:

• Literacy level

• Nerves

• Preconceptions

• Culture

• Ambiguity/semantics

• Mood/emotions

• Distractions

• Etc

Create

‘Basic research ( fundamental or pure research) has as its primary objective the advancement of knowledge & the theoretical understanding of the relations among variables…. It is conducted without a practical end in mind although it can have unexpected results that point to practical applications. The terms ‘basic’ or ‘fundamental’ research indicate that, through theory generation, basic research provides the foundation for further, often applied research’

Wikipedia

16

Create

Applied research ‘is directed towards specific objectives such as the development of a new drug, therapy or surgical procedure. It involves the application of existing knowledge, much of which is obtained through basic research, to a specific..… problem’

New Jersey Association for Biomedical Research

Research leads to creation of new information. An individual can keep it to him/herself or record it & make it available to others

Seminar in Library & Information

Science

17

Collect

Information/knowledge is recorded in a variety of formats & then made available for collection. Some knowledge may be made publicly available for free or for purchase; some information/knowledge may be kept confidential or have restricted access

Organisations & individuals collect recorded information in a systematic way, ie to satisfy their information needs

Seminar in Library & Information

Science

18

Organise

To make it easier to find required information sources, organisations & individuals arrange collected documents in a coherent way eg by:

• Subject/topic

• Format/medium

• Date creator/author

• etc

Organisation should match the information seeking behaviour of potential users

Seminar in Library & Information

Science

19

Store

Information may be kept for short or long periods of time. Storage needs to balance:

• Cost

• Suitability to format/medium

• Preservation needs

• Speed of retrieval

• Security needs

Orgnisations adopt a range of storage methods for different information sources

Seminar in Library & Information

Science

20

Access

Information seekers require some methods for locating useful information/documents.

The larger the quantity & the greater the diversity of information collected, the more complex the access systems required.

Catalogs & indexes are typical access systems

Access informs the information seeker that a document exists (or doesn’t) within a collection & where they can find it

Seminar in Library & Information

Science

21

Deliver

Delivery involves the information seeker gaining possession of the document. Organisations provide different levels of delivery based on:

• Nature of the items sought

• Nature of the information seeker

• Preferred format of the document

• Cost

• Security

• etc

The information seeker can then use the information

Information system

Abstraction 1

In any information system, the ‘real world’ is represented by a collection of data abstracted from observations of the real world & made available to the system

Abstraction 2

A user’s information need, whether for production, storage, or retrieval of information, is abstracted into a form that is commensurate with the information system to be used
