NicerCover v2: A Serverless Webapp for Social Networking on Top of Scientific Portals

.

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/discussion02

Example Usecase: A Research Team

• team leader PUSHes all its context to team members

• team members TRUST all PUSHes from team leader, but also PUSHtheir own context to him/her

• team leader aggregates all PUSHes from one team members anddistributes them to others

Serverless WebApp

.Serverless Webapp..

.... runs from a static HTML and uses cloud APIs for storage

• indexing (database) in cloud drives 02

• large-scale crowdsourcing: the Maps2Graphs project 04

• various browser-based apps like crawlers 03, etc.

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) andbackground 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


10/24

.

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 theabove

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|sync−trust|sync (2)

Epush,first = Cpublic + C|sync−trust|sync (3)

Epush,second = C|nopush|nopush (4)

Cloud APIs


17/24

.

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

Dropbox API Keys (1/4)

Create a Dropbox API app and get your keys. 1 private

Your own library. Only writable by your NiceCover . DO NOT share these keys!

public A copy of your information for others to get. Readable/writable both ways, by design.
