Outline of Final Research Achievements |
Based on the National/International standard of occupation/industry code (SSM/ISCO/ISIC), the system can assign three candidate codes to an answer of an open-ended question in a social survey. And a three-grade confidence level was assigned to the first-ranked predicted code by using classification scores. Many functions are implemented in this system, for example, an ISCO/ISIC code can be assigned to the SSM code automatically, also maintenance function contained. This system is now released to the public. Researcher can use it through the official website of CSRDA. A new automatic coding system for social surveys is in development, which contains an open-ended question.
