(Regular expression to match standard 10 digit phone number) | -| SSN | U.S. social security | \b\d{3}-\d{2}-\d{4}\b | Rejects “000-” starts & “666”. (Add later if needed.) | -| CREDIT_CARD | Visa/Mastercard/AmEx | `\b(?:4\d{12}(?:\d{3})? | 5[1-5]\d{14} | -| IP_ADDRESS | IPv4 + v6 | `(?:\b\d{1,3}(?:.\d{1,3}){3}\b | (?:[A-Fa-f0-9]{1,4}:){7}[A-Fa-f0-9]{1,4})` | -| DOB | Dates like MM/DD/YYYY or YYYY-MM-DD | `\b(?:\d{1,2}[/-]\d{1,2}[/-]\d{2,4} | \d{4}-\d{2}-\d{2})\b` | -| ZIP | US ZIP / ZIP+4 | \b\d{5}(?:-\d{4})?\b | Locale-specific; extend with postcodes later. | - -

All patterns compiled with re.IGNORECASE | re.MULTILINE and wrapped in r'' raw strings.

2. Return-value schema

-

2.1 Keep the dict-of-lists for backward compatibility

-
from typing import Dict, List
-
-Annotation = Dict[str, List[str]]
-
-# e.g. {"EMAIL": ["[email protected]"], "PHONE": ["555-555-5555"]}
-
-
- -

2.2 Offer an optional structured model (new but additive)

-
from pydantic import BaseModel
-from typing import List
-
-class Span(BaseModel):
-label: str # "EMAIL"
-start: int # char offset
-end: int # char offset
-text: str
-
-class AnnotationResult(BaseModel):
-text: str
-spans: List[Span]
-
- -

Why both? Existing users don’t break; new users get richer data. The regex annotator returns both:

-
regex_result = {lbl: [s.text for s in spans_by_label[lbl]] for lbl in spans_by_label}
-return regex_result, AnnotationResult(text=input_text, spans=all_spans)
-
-

TextService will pick whichever format the caller asked for.
