NSW Natural Resources Thesaurus:  NSW Natural Resources Thesaurus Detailed Review and Discussion Alignment with Agencies Draft Thesaurus - Review:  Draft Thesaurus - Review Based on GEMET Added ISO/DIS 19115 Topic Category codes as Groups mapped codes to top terms Proving up the Thesaurus:  Proving up the Thesaurus Test the list of terms against Agency lists Map Agency classifications to the draft Thesaurus classification Outline a maintenance regime Agency Terms Lists:  Agency Terms Lists Agency Terms Lists:  Agency Terms Lists Correspondence not always easy to guess plural or singular “sewage systems” or “sewage system” word order “state of environment report” or “report on the state of the environment” local language “aeroplane” or “aircraft” First pass analysis undertaken and published Second pass must be by subject matter experts Agency Term Lists:  Agency Term Lists Summary of the review Of 10,000 terms reviewed on the first pass all but 36% already exist within GEMET. Of these 36% only 20% are natural resource terms. On this basis we expect that the draft thesaurus needs to include about another 300 to 500 terms to accommodate natural resource term usage within NSW and the Commonwealth Agency Terms List Examples:  Agency Terms List Examples OK OK OK ? Agency Term List Examples:  Agency Term List Examples ??? ??? Maintaining the Thesaurus - Add/Edit a term:  Maintaining the Thesaurus - Add/Edit a term If the term exists, is the hierarchy right? If not consider carefully. Is it worth moving away from GEMET? If yes, determine the new relationships get Agency agreement to the new term/relationships promote new relationship to GEMET? publish the new and versioned thesaurus. If the term does not exist add the new word under a formal change management methodology add the term relationships get Agency agreement to the new term/relationships publish the new and versioned thesaurus. Classification:  Classification The purpose of a classification is to present an Agency’s view on the natural resources and environment field. Those areas that are deemed within their brief Those areas that are deemed important to publish data on (both by the Agency and the public) Review of classifications:  Review of classifications The purpose of the review was to: map the two terms hierarchies and see if: there is a corresponding term in the draft thesaurus the corresponding term is in a similar logical position in the terms hierarchy Agency Classifications:  Agency Classifications Classification Examples:  Classification Examples Classification Examples:  Classification Examples Classification Examples:  Classification Examples Classification - Summary:  Classification - Summary Most classifications have mapped well “Water/surface water quality/exceedance of surface water quality objectives” maps to “Environment.Environmental assessment” “Water/surface water quality/surface water salinity” maps to “Environmental effect” Many have single class to multiple class mapping Single class maps to a much broader class “concentration of ozone depleting substances” maps to “Atmosphere.effect” Maintaining the Thesaurus:  Maintaining the Thesaurus Editing or adding a term Editing or adding to the classification Using the Thesaurus:  Using the Thesaurus Web searching 1. Enter a term from the thesaurus - help could be given with a fuzzy search example?+ 2. Search from Groups to top terms and so on down the hierarchy show CERES example here 3. A pre-defined template The terms do not need to be all from the same “level” nor do all terms have to be displayed. Show report example here Indexing techniques select a word by using the thesaurus and drilling up and down the hierarchy. When a term is selected all terms above it in the hierarchy are also tagged to the data set. Custodianship:  Custodianship The data sets classification may point at the outset to custodianship by virtue of the number of publications by each Agency.
