Assignment 1/2

• Implementation (50%)

1. Mining scientific papers and compute altmetrics (25 pts)

• Use rOpenSci to first search in arxiv.org for papers related to a

topic of your choice and then to retrieve with rAltmetric their altmetrics (http://ropensci.org)

• Result: List of 10 dois from arxiv.org with altmetrics, according altmetrics

from altmetics.org (10 pts)

• Plot and interpret the results
• Result: plot and textual interpretation (15 pts)

2. Use #altmetrics14 Twitter collection (25 pts) http://figshare.com/articles/An_altmetrics14_Twitter_Archive/1151577

• Extract mentions of users (user A mentions user B in tweet)
• Result:Table: userid userscreenname mentions (10 pts)
• Plot mentions in matrix
• Result: plot and textual interpretation (15 pts)

Assignment 2/2

• Final Report (25 points)
• Read related work and collect the papers in Mendely group (tag it

with your name) (5 pts)

• Write a scientific paper (4 pages) (20 pts)
• Upload your paper and your source code in Mendeley (tag it with

submission_yourname, e.g. submission_xyz)

• Presentation (25 pts): Present your paper in class
• Motivate the work you have done (e.g. why altmetrics) in 1 slide
• Present your results and your methodological approach
• Bonuspoints: Present your own ideas for the Twitter dataset and

how you would tackle them à further bonus points if you implement and present them J

Short intro into R

• The R project for Statistical Computing
• http://www.r-project.org
• Free software environment for statistical computing

and graphics

• Classification, clustering, statistical tests, time-

series analysis,...

• Simple way to produce „publication ready“ plots
• Windows, unix, osx: CRAN mirror.

The package rAltmetric

• Package that enables to retrieve altmetric data from

altmetric.com for publications

• Altmetric tracks what people are saying about

papers online on behalf of publishers, authors, libraries and institutions.

• http://cran.r-project.org/web/packages/rAltmetric/
• http://ropensci.github.io/rAltmetric/
• 2 major functions:
• altmetrics() - Download metrics
• altmetric_data() – Extract data
• Plus: functions to plot/print metrics

Analysis of Twitter dataset

• Determine impact of users at a scientific conference
• Extract mentions of users (user A mentions user B

in tweet)

• Hint: think about deduplication, dataset cleaning
• Plot mentions in matrix and interpret results

Write a scientific paper about your work

• 4 pages Springer LNCS format:
• http://www.springer.com/computer/lncs?

SGWID=0-164-6-793341-0

• Structure of the paper:
• Abstract (= a short, complete summary of the paper with key findings)
• Introduction and Related Work (describes the theoretical background,

indicates why the work is important, states a research question)

• Why is the work important? You can borrow from papers you read – but

you need to cite the paper correctly, rephrase, what you‘ve read in your

• wn words and comment if your work differs from it
• Experiments and Results
• Conclusion and Future Work
• Conclusion: Report main findings.
• Future Work: how would you go on with this work
• References
