Important terminology
Frequent words and multi-word phrases across the lead, headings, infobox and body. Useful for terminology coverage.
Use these terms to understand the vocabulary surrounding the topic, not as a checklist for keyword stuffing.
Relationships are represented as Subject → Predicate → Object triples. Confidence describes extraction strength, not the real-world importance of a relationship; lower-confidence rows may be contextual rather than explicit.
TTTA extracted 94 structured relationships around Caltrans. Examples in this analysis include Caltrans → Agency executive → Dina El-Tawansy, Director and Caltrans → Annual budget → $16.1 billion (FY 2025–26). The table shows each extracted connection, where it came from and its confidence.
Concept neighborhoods group terms that sit near one another in the extracted graph. They are useful for discovering adjacent language and context, but proximity does not by itself imply a factual relationship.
The concept neighborhoods around Caltrans bring nearby vocabulary together. In this analysis, examples include State, Agencies and Sacramento. Use the clusters to find adjacent concepts and terminology that may deserve separate research.
