HistoryLong-term research project to model classification systems using general conceptual models to support organization and discovery in Semantic Web settings
Can the FRSAD conceptual model be extended to model classification data? (presented at UDC Seminar, 2011)Can the FRBR model be used to represent the complex relationships among different versions of classification systems? (presented at ISKO conference, 2012)

Current Study
Can the FRSAD conceptual model be extended to model classification data in order to derive implementable models for classification systems that involve multiple translations and/or multicultural implementations?

1. FRSAD Conceptual Model
![Page 6: Modeling Classification Systems in Multicultural and Multilingual Contexts](https://reader030.vdocuments.mx/reader030/viewer/2022020220/56814347550346895dafbe91/html5/thumbnails/6.jpg)
The core of the FRSAD conceptual model
FRSAD Part 1: WORK has as subject THEMA / THEMA is subject of WORK
FRSAD Part 2: THEMA has appellation NOMEN / NOMEN is appellation of THEMA
NOMEN = any sign or sequence of signs (alphanumeric characters, symbols, sound, etc.) that a thema is known by, referred to or addressed as

2. FRSAD model for classification systems• Thema corresponds to the full category
description of the class• Nomen is the symbol (or surrogate) used to
represent the full category description

3. DDC translation case study
![Page 12: Modeling Classification Systems in Multicultural and Multilingual Contexts](https://reader030.vdocuments.mx/reader030/viewer/2022020220/56814347550346895dafbe91/html5/thumbnails/12.jpg)
Relationships between DDC classes in translations
1. Thema [class] 22/eng = Thema [class] 22/swe 2. Nomens may be used interchangeably (if not
limited by a language-specific attribute)
![Page 13: Modeling Classification Systems in Multicultural and Multilingual Contexts](https://reader030.vdocuments.mx/reader030/viewer/2022020220/56814347550346895dafbe91/html5/thumbnails/13.jpg)
Equivalent classes at same notational level

5. Use cases
• Translation• Mapping• Integration• Discovery
![Page 21: Modeling Classification Systems in Multicultural and Multilingual Contexts](https://reader030.vdocuments.mx/reader030/viewer/2022020220/56814347550346895dafbe91/html5/thumbnails/21.jpg)
Example: Integration (Virtual scope note)T2—4888 (22/eng)
T2—4888+ (22/swe)
![Page 22: Modeling Classification Systems in Multicultural and Multilingual Contexts](https://reader030.vdocuments.mx/reader030/viewer/2022020220/56814347550346895dafbe91/html5/thumbnails/22.jpg)
Example: Discovery
T2—4888 (22/eng) T2—4888+ (22/swe)
Relative Index term “Pajala kommun (Sverige)” retrieves T2—4888 (22/eng) or T2—488846 (22/swe)

6. Future work• Model Relative Index as a separate controlled
vocabulary under the FRSAD conceptual model to explore topic-centered approach (exploratory work under way by R. Green)
• Investigate mapped terminology from other controlled vocabularies
• Investigate mapped relationships between different classification systems
