The document provides an overview of the NIF Services which include a curated index of literature and data resources totaling approximately 200GB. The services allow users to search over literature and federated data, retrieve metadata and full text, and perform natural language processing tasks such as entity recognition and topic modeling. The services are implemented using open source technologies like Java, Jersey, Solr, and will be made openly available.
