**Senzing Data Model**

There is an improved, regularly updated [parsing model](https://github.com/openvenues/libpostal?tab=readme-ov-file#installation-with-an-alternative-data-model) from Senzing. "Accuracy improvements averaged more than 4% for all countries, but improvements in specific countries were as high as 87%." 27 nations have 10% or greater improvements in accuracy.

To build Libpostal with the new model, alter the `configure` command above:

```bash
./configure --datadir=[...some dir with a few GB of space...] MODEL=senzing
```
