The following list of key concepts from the previous chapters is a reminder or checklist of what can be used in solving information problems, e.g. in the following exercises.
- Symbolic representation
- Symbols, properties and relations
- Symbols and things
- Symbols versus implementation mechanisms
- Graphs: objects and relations represented respectively by vertices (nodes) and edges
- Directed graphs (digraphs): graphs consisting of nodes and arcs (edges with a direction)
- Abstraction: visual versus mnemonic
- Solids and voids in building representations
- Paradigmatic and syntagmatic dimensions
- Data and information instances
- Semantic data types: primary, anti-data, derivative, operational, metadata
- Information instances by scope: single symbol versus multiple symbols
- Structured, semi-structured and unstructured information sources
- Information flow: what, who, how, when
- Completeness, coherence and consistency
- Information authorship versus information custodianship
- Process diagram: sequence of tasks in a digraph representation
- Information diagram: information instances and flows
- I‑P‑O: transition from process to information management
