Introduction
The introduction discusses the need for machine-driven approaches to scientific knowledge discovery, particularly in the context of COVID-19 research. It highlights the importance of extracting information from structured formats like tables, which contain significant latent knowledge.
Entity Linking for Scientific Text and Tables
This section explains the process of entity linking, which involves matching entity mentions in documents to known entities in a knowledge base. It emphasizes the importance of linking entities in tables to infer their semantic meaning.
Wikidata: Reference Knowledge Base
Wikidata is described as a multilingual knowledge graph that provides common data for Wikimedia projects. The section details its structure, including types and properties, and its relevance to biomedical vocabularies.
