Ushahidi crowdsourcing

Technology Ushahidi was created with a purpose of reporting different events (ongoing anywhere in the world) and pinning them on a map. Ushahidi platform uses crowdsourcing for information collection, data visualization and collective mapping.

In example it is used for monitoring elections:

In a mentioned example, reported events are such as about transparency of elections or different abuses which were noticed by collective or individual people. What is important is a verification of information credibility, which have formal considerations described below in a form of a manual:


Kickstarted most active users

Kickstarter is a crowdfunding platform. The company’s stated mission is to help bring creative projects to life. Kickstarter claims it has received over $1 billion in pledges from 5.7 million donors to fund 135,000 projects

1. Introduction is a modern responsive internet portal, but it can be also understood as a society of backers – they are users which can be identified as simply altruists devoting their time and money for the sake of different startups* registered as Kickstarter-projects. Anyone can create a project (startup) on the portal, for which users are pledging money (collected upon successful amount pledged).

Kickstarter is also a:
multi-dimensional social network (mdsn)

Users registered on the portal have a possibility to give their Facebook account id

a good source of start-up language and a rich English text corpus

All projects are by obligation described in English language, and it’s a lingua franca here on this portal.

semi-collaborative network

Kickstarter users can share ideas and tips between them and project owners.

possible competition and attention attracting medium

2. What are the micromotives of backing a project?

The mainstream thinking is that a user is interested mostly in helping a project to happen by adding a small share to the fund, and a reward is a think of second importance. On the other hand, an open secret is an obvious hand that crowdfunding sites can be understood as gadget shops with delayed shipping. Items with a bargain price are disappearing from the list of available perks really really fast.

2. Creating list of active Kickstarter backers

One of the main goals can be creating a table of “most active Kickstarter backers”, updated annually, let’s say every month. Similar data pages exists on other portals, i.e. GitHub ( Such statistic would be generated basing on number of contributions. According to this definition, to get to the top of list a user should back as many projects as possible (amount of pledge is not important here). It’s not possible publicly to get amount of money which a backer pledged on a project. Still, these are the available data per project:

– Number of backers
– List of backers
– Total money pledged
– Number of backers per reward (reward have a description text and a minimum pledge amount in project currency).

Please note, that a backer can pledge money (back a project) without getting a reward, thus total number of backers per reward is less or equals to total number of backers. By visiting user profile, it’s possible to get a list of projects he backed.

2.1 Side problems and interests

2.1.1 Guessing amount of pledge inside a project
2.1.2 Language analysis Redefine the “start-up specific language” How text and language used affects success Create a corpus
2.1.3 Moaarrr statistics provides some statistics publicly on website
There are many interesting problems which are still unresearched by portal workers neither scientists (regarding my best knowledge).

2.1.4 Predicting success – how ?
2.1.5 Overmeeting goals (overpledging) – start-up gets more money than they thought…
2.1.6 Try to create a Multi-layered multidimensional social network (GitHub + Kickstarter + LinkedIn…)
