[RFC] Files Recommendations: Improve algorithm and data sources

Goals

I think we can improve the current state.
Right now we support three providers:

• Recently Commented
• Recently Edited
• Recently Shared

Sources suggestions

• Recently Accessed
• Recently Uploaded (because we keep the mtime when uploading, so new files might not appear as Recently Edited)
• Frequently Accessed
• Time of day: Accessed files during specific time of days ?

Aggregation bonus

• Some data could be regrouped too. Like if you frequently access more than x files in the same folder, also recommend the folder directly?

Distribution

I also suggest to add a weight combining score
Something that can be fined tuned over time, but we could weight the relevancy of a result if it matches multiple criterias (dumb values used for this example below)

$score = (
    0.3 * $recencyScore +
    0.2 * $frequencyScore +
    0.1 * $editScore +
    0.1 * $sharedScore +
    0.1 * $commentedScore
);

Start by reviewing the existing Recently Commented, Recently Edited, and Recently Shared providers, then assess the proposed Recently Accessed, Recently Uploaded, and Frequently Accessed sources. Define a concrete aggregation and weighting model before implementation; the issue does not identify files, tests, or a verifiable completion target.
