B4. Advanced Lexical Relations II 

This lesson, the second part of Advanced Lexical Relations, expands on how to design and use new lexical relation types in FLEx (FieldWorks Language Explorer). It builds on B3, which introduced the framework and reference set types.

Key content includes:

• Reviewing structural choices for new relations: collection, scale/sequence, tree, pair (one or two names), and unidirectional.
  
  

• Sequence/scale relations: Ordered lexemes (e.g., days of the week, degrees of comparison). Activities include customizing display separators and reordering.
  
  

• Tree relations: Hierarchical sets with a head and subordinates (e.g., whole-part, generic-specific, individual-group). Learners practice creating new types like Individual–Group.
  
  

• Pair relations: Exactly two lexemes, either with one name (e.g., antonyms) or two names (e.g., male–female, singular–plural). Activities cover creating complementary antonyms and distinguishing sense vs. entry level.
  
  

• Unidirectional relations: Only one side displays the reference (e.g., classifiers like grain de riz).
  
  

• Entry/Sense relations: Linking at mixed levels, though less common (e.g., near synonyms).
  
  

• Configuration practices: Customizing display (names vs. abbreviations, commas vs. semicolons) and duplicating nodes for flexible formatting.
  
  

• Best practices: Don’t change underlying structures of existing relation types, keep semantic links at sense level and form-based links at entry level, and handle unidirectionality carefully.
  
  

The lesson concludes with activities, project backup instructions, and a quiz to reinforce understanding.
