Principle of Transcriptivity
Pre-“texts“
TranscriptInter- or intra-medial Transcription
Understandingand Critique
1. Set of (multimedia) pre-“texts“ condensed and structured, e.g. by metadata
2. New „reading“ of pre-“texts“ enabled
3. Discoursive knowledge creation process stimulatedselection of pre-“texts“ and transcription itself
Transcribing – Media/Reading

Possible (scholarly) Metadata Original movie poster displayed
at US cinemas 1959 Otto Preminger movie
„Anatomy of a murder“ Transcripted from the opening
credits of the movie Saul Bass (saul-bass.com)
– Invention of self-contained titles– Unions forced Hollywood to credit
technicians in movies– „Vertigo“, „The man with the
golden arm“

Transcribed German version of the movie poster
Transcribed / Re-addressed– German language use– Layout / Design– Citations inside the media
Culturally localized– Different cultural interface– Optimizing address space
Consequences for verbal metadata?

Learning Talmud Traditionally Talmud schools (Jeshiwot) as community of practice
– Talmud as authoritative source of knowledge– Discussion of dialogic encyclopaedia in small groups– Teachers as walking mentors in the learning process
In University– Basic Hebrew language skills– Usually short texts studied in class– Need to understand structure of complete texts– Need to learn connected knowledge (e.g. use of standard
phrases and arguments, hermeneutical rules)

Learning Entrepreneurship• Learned in Entrepreneurship Centers together with
university teachers and people from practice • Additional skills necessary not available in textbooks
but role models• Know why• Know how
– Idea, technology, business knowledge – Communication, negotiations, etc.
• Know who– Networking, team building, consulting for customers and suppliers
• Know when– Window of opportunity, market entry, growth, exit
• Know where

Media theory for learning communities
Strategies of Transcriptivity– collection of learning materials are re-structured by new media– no media-independent semantic knowledge– ontology design is inherently media- and community-dependent
Strategies of Addressing– Freely designed digital media foster globalization of
address spaces – Personalization and context adaptation are success-critical to
learning
Strategies of Localization– re-organization of localities stimulated by new media– new community-ware for self-organized discourses

Semantic KnowledgeNon-verbal vs. Verbal
Linguisticness
Paradigmatic vs. Syntagmatic
Verbal Models, Metadata &
Ontologies
Structured vs. Semi-structured
Semantic Domain modeling
Figurativeness
Content vs. Cultural Interface
Feature extraction
Content based retrieval
(Histograms, Query by
Humming etc.)
But what about knowledge creation aka learning?

Conclusions Personalizing metadata for learning communities
– Applied media theories – Transcribe digital media thus enabling better addressabilty– Oscillating transcription of verbal and non-verbal
semantic knowledge – Localization of digital media in a community of practice
Architectural and technical considerations in standardized metadata usage– Sharing semantics through multimedia repositories– Ontology management based on MPEG-7/XML– Personalization by mappings between shared and individual
semantics
