A New Approach to StyleA New Approach to Style
• Hypothesis: style = blending principles• Developed for language, but ok for other media• Intended applications:
- Computational multimedia narrative
- User-interface design
- Gaming
- Maybe database queries & integration

What is Style?What is Style?
Style is not just statistics!
Style is fundamental to meaning:
- not just way to present “content”
- not separate from “content”
- not surface, deep inside meaning
Probably cannot be fully formalized, but can be better understood by using formalization

Levels of LanguageLevels of Language
• Discourse• Sentence• Phrase (including metaphor)• WordOur system treats differently for pragmatic
reasons, but distinction is not strict & not reified.
Indeed, model building is not reality discovery.

Supporting TheoriesSupporting Theories
• Narrative
• Metaphor & Blending (from cognitive linguistics & cognitive semantics)
• Algebraic Semiotics & Structural Blending
• Algebraic semantics (CS theory of abstract data types)
• A bit of category theory

Labov Narrative StructureLabov Narrative Structure• Narrative of personal experience, William Labov,
refined by Charlotte Linde: • Optional orientation (time, place, characters, etc.)
• Sequence of narrative clauses describe events
• Narrative presupposition says occur in same order as given
• Narrative clauses interwoven with evaluative material, provide interpretation, evaluation
• Optional closing: gives summary or moral

Labov Structure in BNFLabov Structure in BNF
<Narr> ::= <Open> (<Cls> <Eval>*)* [<Coda>]
<Open> ::= ((<Abs> + <Ornt>) <Eval>*)*
• Can use to structure story generation• Complex narratives, flashbacks &c, still have Labov
segments• Can also use other format specifications

Algebraic SemioticsAlgebraic Semiotics
• Semiotic spaces have sorts, constants, operations, axioms, constants, with partial ordering on each, and a primary sort
• Semiotic morphisms are partial mappings between semiotic spaces
• “Algebraic semiotics” is ‘brand name’: not aligned with contemporary semiotics, though influenced by Peirce & Saussure

Algebraic SemioticsAlgebraic Semiotics
• Builds on algebraic semantics (as in abstract data type theory)
• Incorporates insights from cognitive linguistics and conceptual blending
• Algebraic definition of blending: lax colimit in order enriched category (3/2 colimit in 3/2 category)

Blending Optimality PrinciplesBlending Optimality Principles
•Integration: Scenario in blend is integrated scene
•Web: Tight connections of blend & inputs (e.g., event in input
construed as corresponding event in blend)
•Unpacking: Easy to reconstruct inputs & connections from blend
•Topology: Elements in blend should participate in same kinds of
relations as counterparts in input spaces
•Good Reasoning: Elements blend should have meaning.
•Metonymic Tightening: Relationships between elements from
same input space should be as close as possible in blend.

Formal Optimality PrinciplesFormal Optimality Principles
• Commutativity
• Type Casting
• Axiom Preservation
• Operation Preservation
• Ordering Relation Preservation
(for priorities & subsorts)

Boathouse Space Boathouse Space (one of 48 blends)(one of 48 blends)
For “resident/boat” to “live-in” “house,” type of “boat”must be cast from “Object” to “Person.”

Conceptual Blending AlgorithmConceptual Blending Algorithm
• Three node types are (left to right): relation nodes, sort nodes, constant nodes.
• Vertical edges connect nodes from different input spaces.• Horizontal edges from relation nodes to sort nodes indicate the sorts that the
relation is defined on.• Horizontal edges from sort nodes to constant nodes indicate the sorts of
constants.

Structural BlendingStructural Blending
• For generative media, need to handle structure, not just concepts about structure (e.g., syntax and discourse)
• “Templates” act as constructors (which are functions)

Disoptimality PrinciplesDisoptimality Principles
Neruda: “I am withered, impervious, like a swan of felt navigating a water of beginning and ashes.”
Rilke: “cheap winter hats of fate”
These violate at least three of the optimality principles and require casting to quite remote types

Future WorkFuture Work
• Computational narrative (improvisational & interactive multimedia narrative)
• Richer media
• More blending principles (more specific)
• Gaming
• Use values in semiotic spaces for blending

ConclusionsConclusions
• Reasonably comprehensive notion of style• But formalization is modeling & implementation tool,
not privileged as ‘real’• Limited sense of history can reside in domains• One sense of evolution is iterative refinement of
optimality principles• Not interested in autonomy: not a goal to explicitly
encode personal & social history (“GOFAI”)• Adequate for reductionist notions of style, but
recognizes situated nature of style
