claimKnowledge extraction is the process of obtaining structured, computer-readable data from unstructured data sources like text or semi-structured data like web pages and markup formats.
claimThe authors of 'Construction of Knowledge Graphs: State and Challenges' expand the scope of knowledge graph construction research to include non-RDF-based models like the Property Graph Model, the integration of structured and unstructured data, and incremental maintenance.
claimKnowledge graphs integrate heterogeneous data from various sources, including unstructured data (text), semi-structured data (pictures, audio), and structured data (databases or other knowledge graphs) in a semantically rich manner.
claimWhile entity resolution typically operates on semi-structured data, deep learning-based approaches have been developed to address entity resolution in unstructured data sources.
claimKnowledge extraction is typically applied to unstructured data inputs like text and may be unnecessary for structured data sources such as databases or other knowledge graphs.
claimKnowledge extraction methods are necessary to transform semi-structured and unstructured data into structured entities, relations, and the knowledge graph data model.
referenceHogan et al. provide a comprehensive introduction to knowledge graphs, covering multiple graph data models, methods for handling unstructured, semi-structured, and structured data, as well as tasks like learning on and publishing knowledge graphs.
measurementPopulating knowledge graphs from semi-structured data is the most common method, while only approximately 50% of the considered solutions or toolsets support importing from unstructured or structured data.

procedureKrishna Subramanian, co-founder and COO of Komprise, recommends that organizations protect unstructured data from ransomware by moving cold, inactive data to immutable object storage where it cannot be modified.
measurementUnstructured data accounts for 90% of all data generated in the last 10 years.
claimKrishna Subramanian, co-founder and COO of Komprise, asserts that unstructured data is highly vulnerable to ransomware attacks due to its large surface area, widespread use, and rapid growth, and that cybercriminals can use it as a Trojan horse to infect enterprises.
Enterprise AI Requires the Fusion of LLM and Knowledge Graph linkedin.com Jan 2, 2025 2 facts
claimClinical decision-making in healthcare faces three primary challenges: high data volume (including evidence and patient data), the prevalence of unstructured data (such as clinical notes, imaging reports, and discharge summaries), and non-deterministic, judgment-driven decision-making.
claimAI agents are most effective in healthcare scenarios that involve at least two of the following: high data volume, unstructured data, or non-deterministic decision-making.
