Company Name:  EBSCO Information Services

EBSCO Information Services (EIS) provides a complete and optimized research solution comprised of e-journals, e-books, and research databases - all combined with the most powerful discovery service to support the information needs and maximize the research experience of our end-users. Headquartered in Ipswich, MA, EIS employs more than 2,700 people worldwide, most now working hybrid or remotely. We are the leader in our field due to our cutting-edge technology, forward-thinking philosophy, and outstanding team. EIS is a company that will motivate you, inspire you, and allow you to grow. Our mission is to transform lives by providing relevant and reliable information when, where, and how people need it. We are looking for bright and creative individuals whose unique differences will allow us to achieve this inclusive mission around the world.

At the intersection of product management, data engineering, and customer-based interface design, sits the knowledge engineering team. The knowledge engineering team operates in a multi-faceted role. They perform complex data analysis to prioritize the greatest opportunities to improve knowledge representation of controlled vocabularies, knowledge extraction from full text, and bibliographic data. This team, siting within search, helps develop data pipelines that bring a multitude of data sets into the EBSCO knowledge graph, and they help define new data elements to help in the users’ search for scholarly content. Members of the team own the end-to-end development of knowledge graph features for EBSCO search, query expansion, disambiguation, and visual search within the EBSCO product lines.


Growing the Knowledge Graph requires the development of knowledge models describing how entities relate to one another for topical and bibliographic search and discovery. We use machine learning, linked data, and semantic techniques to create the graph as well as deduplication, entity extraction, matching of subjects and entities from our millions of full text records. In addition, we also use graph-ML techniques like shortest path, random walk, betweenness centrality, and Louvain modularity to gain insight from the knowledge graph for use in search aids on product.

As a Knowledge Engineer on the Knowledge Graph team, which consists of architects, knowledge engineers, taxonomists, and UX designers. You will contribute to the knowledge organization of EBSCO’s metadata assets, primarily multilingual controlled vocabularies, knowledge extraction, and bibliographic metadata, by modeling metadata schema, analyze graph structures and content, develop new semantic representations, and work with providers and consumers of data to guide the development and usage of knowledge structures to improve entity accessibility and enable automated reasoning. You will use a variety of semantic modeling techniques, judging tradeoffs between formality and usability for the knowledge extracted from content. You will also be establishing ETL processing rules and data processing workflows, working with linked data, mining for data internally and externally, and collaborating with the Product Management, Search, and Architecture teams in order to improve the search and semantic enrichment of EBSCO products through graph technology and data visualization methods.
