This is the 2nd version of the NiceCover webapp. The 1st version aimed at socially distributed knowledge generation which in testing proved to be excessively bulky for ordinary users. This version rectifies this problem by simplifying the design to the level of the well-recognized 'like-follow' usage pattern. However, the design is still original in that it allows for socially distributed multihop paths between end users and the content hosted at a scientific portal. This paper presents the core idea as well as introduces the fully functioning software. The webapp follows the serverless design where both the application and data are hosted in users' own cloud drives or locally in browsers.

NiceCover v1 (failed)
• LOIS presentation 01
• too complicated
◦ a tree/mesh of context nodes
◦ unclear pull/push design

NiceCover v2: Still Wanted?
• SNS Today: content distribution network
◦ the target is to get more people visit the product page
• NiceCover: context sharing network
◦ content is converted into context (content is not essential)
◦ context is shared, discussed, rated, etc.
• merit: any format/protocol can be applied to context and its handling
◦ most SNSs today have a fixed framework
• example: one cannot use Twitter hashtags for scientific context/discussion

Example Usecase: A Research Team
• team leader PUSHes all its context to team members
• team members TRUST all PUSHes from team leader, but also PUSH
their own context to him/her
• team leader aggregates all PUSHes from one team members and
distributes them to others

Serverless WebApp: 2 Designs
• Standalone: static HTML put in a cloud drive and shared
◦ JS/jQuery is inside the HTML file
◦ merit: any browser, any device
◦ demerit: no autoparse
• Browser Extension
◦ Chrome is the easiest to write, has floating (panel), inpage (autoparse) and
background JS scripts
◦ merits: autoparse, flexibility, ...
◦ demerit: local to your Chrome browser

Social Networks : Push vs Pull
• PUSH: A can post in B's space (facebook)
◦ participation cost: B has to accept A as a friend
• PULL: A can listen to B's broadcasts (twitter)
◦ participation cost: A has to find B
• ... there are PUSH and PULL hybrids (facebook wall)

Useful Features
1. autoparse: parse context automatically from pages on certain portals
◦ example: Mendeley
2. autosync: sync context between A and B, automatically
3. .. both features have direct effect on participation cost

Private, Public, Readonly
• PRIVATE: read-write access, normally A's own context
• PUBLIC: A's space made public, can be accessed (written) by B
• READONLY: A's space made public which cannot be written to or replaced
• ... plus the TRUST parameter which can create multiple modes for each of the
above

Participation Cost Optimization
• action is both the qualitative and, when in |action| form, the quantitative unit
• C is unit cost of action(s), E is overall cost estimation
• C|action|
is the cost of a given action times (not the power) the count
• Epull,first the total cost for a given interaction
• A = FIRST, B = SECOND
Epull,first = Cpublic (1)
Epull,second = Cprivate + C

Cloud APIs and Automation
• Dropbox is the best Storage API
◦ full automation possible -- see the process below
◦ also full isolation -- permanent set of keys
• Google Drive API is more restraining, but can be worked out
• all the others are even worse than Google Drive API
