A STUDY OF REPOSITORY NETWORK

Distribution of popularity & Effect of coexisting languages

SLIDE 2

Introduction

SLIDE 3

Distribution of Popularity

Users save favourite projects into their list (Watch)
Users keep a copy of the project (Fork)
GitHub Trending for popular projects

What is the distribution of popularity

f the projects on GitHub?

Interesting Phenomenon: only a few websites are popular

SLIDE 5

Experiments

Data: GitHub Archive of Events in April 2015
WatchEvent and ForkEvent
We process more than 300,000 repositories
Goal: to find the relationship between the number of

watch/fork and the number of repositories

SLIDE 8

Summary of Distribution of Popularity

The distribution follows the power law
It is the same as the popularity of websites

SLIDE 9

Summary

The Swift does have impact on Objective-C
It attracts a certain number of users
Java is not strongly related

SLIDE 15

Conclusion

Two properties of large scale repository are presented
Popularity of projects
Impact of two similar programming languages
External factors
