attention - the temporal dimension• we share with others what captures our attention
• and when it fades we search for novel experiences

how does novelty interact with collective attention?
in a highly nonlinear but predictable way

drivers of attention: popularity versus novelty
rt = e−αtβ
the larger beta the faster novelty fades
O1----novelty
O2----popularity
F. Wu and B. Huberman, Proceedings of the ACM e-commerce conf. 2008
a mechanism for dynamically configuring websites
By measuring the popularity of any content/link, and novelty decay, we maximize attention to online sites with dynamic content.
i-catcher:
social networks that matter• scholars, politicians and advertisers value social networks• but often the linked structures do not reveal actual
interactions• intimate networks – the result of a scarcity of attention
a study of twitter- B. A. Huberman, D. M. Romero and F. Wu, First Monday Vol. 14 (2009)

Friendleeambient awareness of intimate social
relationships
• To stay in close touch with people close to you (family, close friends etc.)
• Intimate phone-based social network automatically identified and ordered by closeness of connections
• Share personal context (availability, status, location, local time, weather, etc.)
• Browse connections of close contacts
• Search for and get recommendations for people and businesses from trusted social network
• Lean and compelling interface to maintain real-life social contacts

crowdsourcing and attention
the tragedy of the digital commons (Adar and Huberman -2000)
rational for individuals not to upload content and free ride on the production of others.
jointness of supply
but if everyone reasons this way no content is produced
a puzzle: content provision persists at levels hard to understand
examples: digg, youtube, flickr, wikipedia, etc.

the value of attentionan insightful experimentB. A. Huberman, C. Loch and A. Onculer, Social Psychology Quarterly, Vol. 67, 103 (2004).
a study of 10 million videos submitted by .5 million users to youtube
Results:
1.productivity exhibits strong positive dependence on attention
2.producers compare themselves to others when having low productivity
3.and to themselves to themselves above a threshold
B. A. Huberman, D. M. Romero and F. Wu, In press, Journal of Information Science(2009)
4. productivity is highly skewed (do to feedback effects) F. Wu, D. Wilkinson and B. A. Huberman, Proceedings of the 2009 International Conference on Social
Computing, (2009).

lack of attention and productivity
average number of views vs. i’th to last video. The origin represents
the last video. The average number of views decreases linearly
as contributors approach their last video with correlation of 0.90

attention and reciprocityreciprocity plays an important role in economic exchanges.
it also plays a role in the attention economy
Twitter: 90 percent of a user’s friends reciprocate attention by being friends of the user as well

attention
Question 1: of the millions of videos uploaded to Youtube, how likely are any of these to achieve a great level of attention?
and since “persistence is strongly correlated with success”
Question 2: how does persistent uploading increase the chances of success?

coda
in the age of the web, attention is the valuable resource and thus the focus of a new economy
attention often overshadows financial gain
the competition for attention has consequences for expressive spaces (online content, websites)
it shifts the emphasis from content to style.
