Table 3 Name and description of a few metrics
Name | Description |
|---|---|
Length of metadata II | Number of words in a metadata field. Extremely large or small values may indicate an inadequate choice of metadata to represent the content |
Association between metadata values | The confidence level of an association rule X→Y is an indicator of whether the set of values X makes the set of values Y redundant or not. The higher the value, the more redundant Y is expected to be. This may indicate that implicit practices in the description of content have been developed |
Frequency in search | Number of metadata values in the web access logs. For instance, the frequency of a search using a given keyword. If such a keyword is often searched, probably it will have a high interpretability |
Redundancy of metadata values | Conditional probability P(x|y), where x is one metadata value of a content, and y is another one. High values may mean that y makes x redundant. This may indicate that implicit practices in the description of content have been developed |
