Data Science
The internet is the native environment of information seekers. OCLC Research recognizes that to be integrated into the internet, traditional library data must be transformed in various ways. We are analyzing the data in WorldCat and other sources to derive new meaning, insights, and services for use by libraries and others on the internet. Our work includes:

OCLC Linked Data: Research, experimental applications, and shared infrastructure
virtual
This presentation summarized OCLC's findings on the impact of new workflows in the ground-shifting transition from traditional cataloging to linked data platforms, highlighted the integral engagement, participation, and feedback from OCLC members, and attempted to chart a linked data research path for the decade to come.

Lessons from Representing Library Metadata in OCLC Research’s Linked Data Wikibase Prototype (video)
Hamburg, Germany
This presentation highlights key lessons from OCLC Research’s Linked Data Wikibase Prototype (“Project Passage”), a 10-month pilot done in 2018 in collaboration with metadata specialists in 16 US libraries.

What are the entities that matter, and how much should we say about them?
Virtual
This presentation discusses the work of catalogers who participated in OCLC's Project Passage in 2018. It develops the theme of identification of "the entities that matter" and concludes with a brief update on OCLC's post-Passage activities involving resource description in Wikibase.

How IIIF standards improve search and discovery for Cultural Heritage collections
Tampa, Florida, USA
IIIF is an emerging standard for sharing digital structural metadata. OCLC is an active member of the IIIF community and has been working to integrate the standard in is services/products. This talk discusses the experimental IIIF work being done by OCLC Research to help test evolving IIIF standards and help integrate them into production services.

Introducing the CONTENTdm Linked Data Pilot Project
Indianapolis, IN, USA
The CONTENTdm Linked Data pilot explores how to convert CONTENTdm data into linked data, how to curate the data in the Wikibase infrastructure, and how to use the data to improve end-user experiences in CONTENTdm. This presentation covers the background research that led to the development of the pilot, the plans for the 3 phases of the pilot, and some early feedback from one of the pilot participants.

IIIF Change Discovery in Action: Findings from an OCLC Research Experiment
Göttingen, Germany
OCLC Research is participating in the IIIF Discovery Working Group's on-going effort to develop a "Change Discovery API". The Change Discovery API will provide the information needed to discover and subsequently make use of IIIF resources.

Fast and Discriminative Semantic Embedding
Gothenburg, Sweden
We present a novel, effective and efficient method for term and document embedding method. Our experiments show it outperforms state-of-the-art methods in terms of the STS benchmark and subject prediction when trained on the same datasets, while at the same time being computationally cheaper by orders of magnitude.

An Innovative Approach to Scalable Semantic Embedding
Pittsburgh, Pennsylvania, USA
Semantic search, in addition to keyword based search, is a desirable feature for many digital library systems. Even in the largely structured library data world, there is still a lot of tacit information locked in the free-text fields. Embedding words and texts in compact, semantically meaningful vector spaces allows for computable semantic similarity/relatedness which would make search more intelligent.
