INFORMATION
SCIENCE
We are drowning in data but starving for wisdom. Information Science is the discipline of collecting, organizing, storing, retrieving, and disseminating information to create meaning.
The Hierarchy of Value
The core philosophy of the field is moving raw input up the value chain.
Knowledge Domains
Information Retrieval
The science of search engines. Indexing, querying, and ranking relevance.
Taxonomy & Ontology
The classification of things. Creating hierarchies and relationships between concepts.
Archival Science
Preservation of data for long-term access and historical integrity.
Bibliometrics
Quantitative analysis of written publications and citation networks.
The Inverted Index
How Google works. Instead of scanning every document for a word, it keeps a list of every word and which documents contain it.
Vector Space
Modern search engines don't just match keywords; they map words to coordinates. Words with similar meanings appear closer together in space.
The Knowledge Graph
The future of information is the Graph. Entities (People, Places, Things) are nodes, and edges describe their relationship (e.g., "Leonardo da Vinci" —painted→ "Mona Lisa").
