| # US Address Standardization (PostGIS stdaddr schema) |
|
|
| Chat-format instruction data that maps a raw US address string to a strict JSON |
| object matching the PostGIS `address_standardizer` **stdaddr** type (camelCase keys, |
| USPS-abbreviated values). |
|
|
| Each row has three flat fields (`system` / `user` / `assistant`) for easy reading |
| and grepping; rebuild the chat `messages` list from them at train time: |
|
|
| ```json |
| { |
| "system": "<standardization instructions>", |
| "user": "100 Old Forge Rd, Kent, CT 06757", |
| "assistant": "{\"building\":\"\",\"houseNum\":\"100\", ...}" |
| } |
| ``` |
|
|
| ## Output keys (16, in order) |
|
|
| `building, houseNum, predir, qual, pretype, name, suftype, sufdir, ruralRoute, |
| extra, city, state, country, zipcode, box, unit` |
|
|
| `sufdir` is the post-directional (e.g. `NE` in "Main St NE"); `extra` carries floor |
| info or an intersection's cross street; `ruralRoute` is number-only. |
|
|
| ## Generation |
|
|
| Synthetic, label-first: a valid structured record is composed, then a deliberately |
| messy raw string is rendered from it (varied casing, abbreviation spellings, |
| punctuation). Covers streets, numbered routes, interstates, intersections, rural |
| routes, PO boxes, weird building names, and tricky unit designators. See the |
| `scripts/` folder in the companion model repo for the generator. For exact PostGIS |
| fidelity, labels can instead be produced with `postgis_label.py` against a live |
| PostGIS instance. |
