Los Angeles City College knowledge graph

  1. One map for nine colleges

    20,139 course records and 1,719 programs, joined by 91,798 connections. Each dot is about 50 course records.

  2. LA City College’s part of the map

    Courses sit in the middle. Programs, GE areas, subjects, and instructors connect to them directly, and careers connect through programs.

  3. One course: Programming in JAVA

    CS 113 has 7 connections here. Each one is a stored fact, not a sentence on a web page that has to be found and interpreted.

  4. An old course number still leads here

    CO SCI 141 became CS 113. Transcripts and older catalogs still use the old number, so the map keeps the link between them. RENUMBERED_TO

  5. Prerequisites form a path

    MATH 251 to MATH 261 to CS 113. Each step is its own connection, so the assistant can follow the whole chain instead of stopping at one page. PREREQUISITE_OF

  6. One course counts in several places

    1 program, and through it, 16 careers. A search would need a separate page for each. REQUIRES_COURSE LEADS_TO_CAREER

  7. “What are the prerequisites for CS 113, and is it transferable?”

    The assistant reads prerequisites and transfer status straight from the map. AI only turns them into a sentence, so it isn’t guessing at them from memory.

Read each row as a sentence. The last column is the name the system uses for that connection.

Nine colleges side by side

Course records include retired numbers, which is what lets an old code find its replacement. Each college name opens that college’s page.
