The (two) "Important" boxes in section 4.7 mention that the words metric and measure have precise meanings and that they should not be confused with the words distance, score, or length. However, the preceding block of text appears to use the following terms interchangeably:

  • Distance measures
    cosine distances

  • In one case, the preceding text clearly contradicts the note by conflating measures and scores:

    Distance measures are often computed from similarity measures (scores)...

    Beyond having a specific example of what a distance vs a metric is, which would help the reader follow the "Important" box's admonition, the preceding text should obey the recommended usage.

    Very good point. I need to follow my own advice and be more careful about how I use those terms.
