Information spreads rapidly across Web sites, Web logs and online
paper describes the research framework of the IDIOM Project (Information
across Interactive Online Media),1 which analyzes this process by
content elements, mapping them to an ontological knowledge structure,
and tracking their
temporal and geographic distribution. Linguists define "idiom" as
an expression whose
meaning is different from the literal meanings of its component words.
Similarly, the study
of information diffusion promises insights that cannot be inferred
from individual network
elements. This paper presents underlying technology, initial results,
and the future roadmap
of investigating information diffusion based on ontological knowledge
projects often focus on particular media, or neglect important aspects
of the human language.
This paper addresses these gaps to reveal fundamental mechanisms of
diffusion across media with distinct interactive characteristics.
