NAP-Consistency-Checker: Local SEO NAP and Entity Validation

Type: Commercial | Domain: SEO, Local SEO
Hugging Face: syeedalireza/nap-consistency-checker

Validate NAP (Name, Address, Phone) consistency and entity alignment across pages and citation sources.

Author

Alireza Aminzadeh

Problem

Local SEO depends on consistent NAP across site and citations. Detecting variations and normalizing entities reduces confusion for users and search engines.

Approach

Input: Text snippets or structured NAP fields (name, address, phone) from multiple sources.
Output: Consistency flags (match/mismatch), normalized canonical form, optional entity resolution (same business or not).
Models: Rule-based normalization (address/phone parsing) + optional transformer/NER for extracting NAP from raw text; embedding similarity for entity matching.

Tech Stack

Category	Tools
NLP	Hugging Face Transformers, sentence-transformers (optional)
Rules	regex, standard phone/address parsing
Data	pandas, NumPy

Setup

pip install -r requirements.txt

Usage

python inference.py --input data/citations.csv --reference data/reference_nap.csv --output output/consistency_report.csv

normalize.py provides NAP normalization helpers (used by inference). No separate “build canonical” step; the reference is read from the reference CSV.
