About The Project

This project is an entity normalisation engine developed for the Vector AI recruitment process. It supports entity normalisation for the following types of entities:

• Companies, businesses;
• Products, objects;
• Locations, cities, countries;
• Serial numbers;
• Street addresses.

The model takes as input a stream of strings in the classes above. There is no context provided for each entity.

The model performs a normalisation to suitable Wikipedia articles for the first three types of entities. Given the uniqueness of the latter two types of entities, normalisation is performed according to linguistic similarity of the input entities using the Levenshtein distance.

The model accepts entities in any language supported by the Google Translator API.
