Aurora Facebook comparison: Town page vs the Mayor's two pages

Three Facebook exports, 2025-10-15 → 2026-10-15: the official Town of Aurora page, and Mayor Tom Mrakas's tom.mrakas profile and Mrakas4Aurora page. Each caption was read and classified by Claude Code. Dates are America/Toronto local time. Generated 2026-10-16.

Key findings

• The two mayor pages are close mirrors: 96.1% of tom.mrakas captions also appear on Mrakas4Aurora, and 97.4% the other way. 859 of 868 shared items were posted to both within an hour.

• Almost no caption text is copied between the Town page and the mayor's pages: only 3 Town posts share wording with a mayor post. A further 125 mayor posts cover the same event as a Town post in different words.

• Election content starts on the Town page on 2026-04-01 (neutral voter information only). The mayor's campaign content starts on 2026-03-14.

• 74.5% of the mayor's posts (both pages) are town-related and have no counterpart on the Town page. That is 91.2% of the mayor's town-related posts. See the final stat.

4 · Duplicate content detection

A post counts as a duplicate when its caption matches another post's caption exactly (after normalising case, punctuation, emoji and links), or is a near-copy of it. A near-copy has ≥85% character similarity, or the shorter text is ≥90% contained in the longer, and the two share the same dates and numbers. The date-and-number rule stops recurring templates such as "The Week Ahead – April 6 to 12" from matching a different week. Captions under 25 characters or empty can't be matched reliably, so they're listed separately.

Final stat · How much of the mayor's content is town-related but unique from the Town's own content?

Numerator: posts classified Town related (category 1) that share no caption wording with any Town of Aurora post and don't cover the same event as a Town post in rewritten form. The same-event check uses TF-IDF similarity ≥0.30 within ±7 days, or a shared aurora.ca link. Denominator: all posts on the page.

· caption copied from Town: 6
· same event, rewritten: 125
· no Town counterpart: 1,358
Unique-wording rate (any Town text match excluded): 81.3%

Bottom line: about 74.5% of everything on the mayor's two pages (1,358 of 1,823 posts) is town-related content with no counterpart on the official Town page. With the stricter "no shared wording" test alone, the figure is 81.3%. Because the two mayor pages mirror each other, these posts boil down to 765 distinct items (80.1% of the 955 distinct items across both pages).

Method and caveats

Classification: the 1,622 distinct captions were each read in full by Claude (Opus 5.5) against a fixed rubric. Exact copies share one decision. Each post records a confidence level and a short reason in cc_analysis. Only caption text was available; no images or videos were inspected.
Duplicates compare caption text only. Two posts with different captions on the same photo, or the same caption on different media, can't be told apart. dedup.py sets the thresholds; every matched pair is listed in dup_groups.json.
Same-event matches (topic_matches.json) are a looser tier, used only in the final stat. A match means the mayor covered the same event, not that he copied the post.
"Posted first" uses Facebook timestamps and doesn't prove who wrote the content.
Files in cc_analsyis/: results.json, posts.csv, dup_groups.json, topic_matches.json, classifications/, plus the scripts. To rebuild: dedup.py → topic_overlap.py → analyze.py → build_report.py.
