← Back to Domain-Specific Abstractions by Domain

4 domain-specific abstractions whose origin domain is Information Science.

• Documentalist — An information professional who organizes documentary sources and conducts specialized bibliographic retrieval on behalf of researchers or institutions.
• Information Need — Represent the situated gap between what an actor currently knows and what the actor must know to interpret, decide, or act, allowing the gap to evolve from unarticulated unease into a formal question and system-facing query.
• Literature-Based Discovery — Generate testable hypotheses by linking complementary relations stated in separate scholarly literatures—often A–B and B–C—to propose an unstated A–C connection.
• Units of Information — Choose a logarithmic reference base and unit convention for information quantities so the same amount can be expressed coherently in bits or shannons, nats, hartleys, and their standardized multiples without confusing information with storage capacity.
