PROJECT IDEATo correct the science bias in maps of science that rely upon journal citations

Page 4: Cascades, Islands and Streams

OUR PROPOSAL1. Integrate several datasets representing a broad range of

scholarly activities (not just journal publishing)2. Use method triangulation to explore the lifecycle of

topics within and across a range of scholarly activities3. Develop transparent tools and techniques to enable

future predictive analyses

Page 5: Cascades, Islands and Streams

EXPLORE TOPIC EMERGENCE DIFFERENCESOccurs consistently in one type of activity, then cascades in a linear fashion to other areasOREmerges in one area then flows into other areas (streams)OREmerges in different places and remains in separate islands

Page 6: Cascades, Islands and Streams

RESEARCH QUESTIONSWhat is the nature of topic development in relation to core scholarly activities?How does the type of activity in which a topic appears impact the lifecycle and duration of that topic?

TOPICSCognitive ScienceDigital HumanitiesHistory of ScienceSocial Network Analysis

We will analyse these four broad topic areas

Page 9: Cascades, Islands and Streams

METHODSWord analysis• Words used as proxies for topics to investigate topic

flows over timeTopic modelling• Identifying topics by statistical analysis of word co-

occurrencesBurst detection• Identifying sub-topic emergence by detecting significant

increases in word frequencies

SOME FINDINGSThere was a general consensus about the most popular videos as measured through views or comments on YouTube and the TED site. Most videos were found in at least one online syllabus and videos in online syllabi tended to be more viewed, discussed and blogged.Less liked videos generated more discussion.Science and technology videos presented by academics were more liked than those by non‐academics

->academics are not disadvantaged in TED
