Purpose of the Job

The services that Elsevier provides are becoming increasingly dependent on Smart Content to support Elsevier’s corporate strategy of greater volume, types and sophistication of content. Elsevier is looking for an junior data scientist with a focus on Machine Learning and Statistical NLP techniques to help build state of the art applications for the health sciences domain. Hands on coding of NLP/ML algorithms an absolute must.

The junior data scientist will participate in the the design, prototyping and sometimes implementation of TDM/ML applications for our businesses. These applications have two main goals: cost savings by building workflow efficiencies or revenue generation by building front end features. You will work closely with both the nursing education and health sciences teams. Sample projects may include recommender systems for adaptive nursing content, extracting medical information from medical health care records, or search algorithms.

You will also work closely with the EMMeT (Elsevier Medical Merged Taxonomy) team providing data analytics on EMMeT and related terminologies to support decision-making, designing automated approaches to bulk updates, ontology validation and terminology mappings, and will bring NLP expertise to the team. You will work with a team of medical experts, as well as product leads to determine how to best build and leverage semantic capabilities. Knowledge of database query language (SQL) and scripting language (Python) are mandatory. Experience with Natural Language Processing application is necessary, and experience with medical terminologies such as UMLS, SNOMED CT, ICD-9, ICD-10, CPT, LOINC etc is a plus.

Main Activities and Responsibilties

Text and data mining

Bring active experience in to the organization on extraction text and data information from structured and unstructured data. Applying and developing these techniques, the junior data scientist will drive the implementation of automated indexing and annotation processes.

This work includes the application of Elsevier's taxonomy and ontology assets to a wide variety of content – as well as drive developments in the application of and expansion on these vocabularies.

Data analytics to support businesses and products

Analyze extracted information to drive such processes as automated and manual data cleansing. Data analytics can also be used to identify research trends, or drive decision for our content acquisition strategy. Using visualizations tools to present the extracted data to be ready for consumption will be another key ability.

Contribute expertise on data extraction and NLP matters

Serve as an NLP/Machine Learning expert in the health sciences team. The Junior Data Scientist is also part of the the wider team Content and Innovation team.
