[DEPRECATED] Setting up a server to host Spacy for Named Entity Recognition

With the arrival of our gen AI functionalities (at indexing and searching phase), the Spacy NER has been deprecated as Datafari v6.0

Datafari can be setup to use a webservice to extract named entities through the [DEPRECATED] Spacy Transformation Connector . However to do so, a webservice serving spacy models and allowing to query for entities must be setup. This is what this documentation is about.

Resources Needed

We tested the webservice on a machine with an 8 core CPU and 32GB of RAM for sentiment analysis using spacytextblob and keyword extraction using KeyBERT. The spacytextblob library was using the following language models depending on the language detected in documents:

• "en": "en_core_web_trf",

• "fr": "fr_dep_news_trf",

• "de": "de_dep_news_trf",

• "xx": "xx_ent_wiki_sm"

Resource consumption and requirement will vary depending on the task and models you use. We recommend you read the spacy documentation about the models you plan on using to get an idea of the requirements. Then perform some tests on the webservice before integrating it in an indexation pipeline to make sure it runs smoothly.

Some tasks / model may run better using a GPU when it is available.

Getting the Web-service

We developed a first version of a web-service meeting the requirements of the [DEPRECATED] Spacy Transformation Connector which is available here: https://gitlab.datafari.com/sandboxespublic/spacy-webservice

The readme gives extensive information on how to install, configure and use the web-service.

You can extend the capabilities of the web-service if you need to too. It uses python fastapi library, which is an easy way to build a web API.
