Each event in the 2-week window is scored by gpt-5.2 on five
universal dimensions (1–10). Universal means the scores describe the
event itself — they're the same for every viewer. Two additional
per-user dimensions exist in the schema but are not used in this
page's ranking yet.
Universal dimensions
- Social Quality
- Will attendees actually interact with each other, or just sit in an
audience? Bring-your-friends events (Parks on Tap, Open Streets,
concerts) score moderate even if lively — interaction stays inside
friend groups, not across strangers.
- Serendipity
- How diverse is the crowd, and how likely is an unexpected interesting
encounter? Outdoor public events (parks, streets, plazas) and walk-up
third spaces score higher; private ticketed indoor seating scores
lower.
- Uniqueness
- Is this a rare one-time event or something that happens regularly?
- Community Building
- Does attending build something durable — group membership, recurring
civic relationship, local reputation? Worship services and
intra-congregation events cap at 5 (they build congregation
cohesion, not cross-cutting civic ties). Cultural events that happen
to be hosted at a religious venue are not capped.
- Solo-friendliness
- Can a stranger show up alone and meet new people? 1–3 =
bring friends (beer garden, concert, festival, Parks on Tap, Open
Streets). 4–6 = neutral. 7–10 = built for strangers to
meet (running club, civic meeting, volunteer day, hackathon, book
club, structured class with regulars). The cue: is there structure or
a shared activity that gives strangers an easy reason to talk?

The D column shows the LLM's read on the source data:
● rich (detailed body text),
● thin (a line or two),
● missing (title only). When a
dot is red, take the scores with a grain of salt — the LLM was working
from the event title alone.
Recurring series
Events that share the same title within a source and occur three or more
times in the window are collapsed to a single row. The +N more
pill (hover for dates) shows the additional occurrences.

Per-user dimensions (not in current ranking)
- Interest Match
- Tag overlap with user-selected interests. Not yet wired into this
page — needs a tag picker.
- Value for Price
- Is the event priced fairly for what you get? Distance is intentionally
excluded — everything here is Center City or near it.
What's intentionally not included
No distance term (CC-only). Worship services are capped on community
building. Block-party permits scraped from OpenDataPhilly are scored
conservatively — many are private and we have no way to distinguish from
the permit record alone.
