Ideas to work on for metric integration
- Metric categorization into levels:
- A possible categorization
- Basic: These metrics should only use the checkpoints that can be assessed automatically (with an algorithm). For example: Does the ALT tag has the IMG tag?.
- Semantic or extended: Metrics that use the entire set.
- Pragmatic: Metrics that measure the user experience.
- Motivation: automatic tools will be able to calculate the metrics defined as "basic", with a known error rate.
Limiting the scope in the metrics input will facilitate their programmatic implementation.
Therefore, any evaluation tool could calculate metrics at a know level of accuracy.
