2 Reading James Cook University. National Research Classification s/index.html 4 Once more with feeling.. What s a fundamental difference between an IS and an IM system? And what does this mean for classification systems for business? 5 Purpose of a Classification To enable information to be stored in an organised manner to facilitate timely access and easier access to the right information required to support a business process. More generally, the purpose is to enable information to be managed in a manner that is relevant to the agency s business goals and objectives 6 2

3 Aims of the classification scheme To support the enterprise Relevance [suitability] Logic Consistency Efficiency Quality Management of materials themselves 7 Relevance The scheme must relate to the enterprise s needs. An appropriate scheme will be as small as it needs to be, but provide for growth [extensible]. The facet[s] that provide the basis for the scheme must reflect the requirements of the enterprise. 8 Logical The classification should be able to be apprehended by looking at it. i.e. if it is a system of numbers, then these should be able to be understood by users without the need for extensive training. [Is this possible?] Precisely because the system of classification is arbitrary, it must have a broad-based logic, and not merely an internal logic. 9 3

4 Consistency The scheme must provide for specific terms. [Scope notes and other hierarchical structures may be needed to make this clear.] The scheme must provide for a consistent mapping between the creators understandings and the users understandings of terms 10 Efficiency The classification is meant to bring information objects to meet the information needs of users quickly and easily. The lectures on retrieval of information indicate that the essential problem of IR is mapping query to retrieval structure, and classification is one key way to achieve that. 11 Two Aspects of Quality The aim of the classification is to so support the enterprise that better quality outcomes are possible The application of the classification system is a quality dependant task without suitable control of its application it will impede the enterprise. [There is (still) a need for authority.] 12 4

5 Records Management itself Management of the information that is stored. i.e. Use of the classification scheme to decide when records are split, merged, removed, stored [archived] etc. 13 Custom Schemes or Off-The-Shelf A custom developed scheme will have the advantage of specificity; The disadvantages of non-standardisation. Standard Industrial Classification Schemes, for example, will better enable the local system to interface with external systems, reporting, data migration, transfer to new systems, etc. 14 How Industrial Classifications are used Statistics Funding models [Government] Policy process Trade management Research modeling 15 5

6 Examples Standard Industry Code [U.S. Statistics] The Australian and New Zealand Standard Industrial Classification (ANZSIC) has been developed for use in both countries for the production and analysis of industry statistics. Research Fields, Courses & Disciplines (RFCD) The categories in the Research Fields, Courses & Disciplines classification include recognised academic disciplines & related major sub-fields 16 Standard Industrial Classification Codes CODE DESCRIPTION 1 Agricultural Production--Crops 11 Cash Grains 111 Wheat 112 Rice 115 Corn 116 Soybeans 119 Cash grains, nec 13 Field Crops, except Cash Grains 131 Cotton 132 Tobacco 133 Sugarcane and sugar beets 134 Irish potatoes 139 Field crops, except cash grains, nec 16 Vegetables and Melons 161 Vegetables and melons 17 Fruits and Tree Nuts 171 Berry crops 172 Grapes 173 Tree nuts 174 Citrus fruits 175 Deciduous tree fruits 179 Fruits and tree nuts, nec 18 Horticultural Specialties...
