Introduction

Page 4: Author reward

Introduction Biological data is being generated at a rate faster than ever New research depends on existing knowledge Thus, a comprehensive and up-to-date collection of biological data is of importance

Page 5: Author reward

Introduction Traditionally, knowledge was consolidated through expert curation But, the massive and fast-expanding volume of data has made manual curation laborious and time-consuming

Meanwhile, community curation is gaining ground as a solution to this

Page 6: Author reward

Community curation “Harnessing community intelligence for

knowledge curation”

Page 7: Author reward

Prime Example: Wikipedia

Page 8: Author reward

Wikipedia has inspired several biological wikisShown above is ArrayWiki (http://arraywiki.bme.gatech.edu)

Page 9: Author reward

However, bio-wikis have not made substantial impact because of a lack of

participation from the scientific community

Page 10: Author reward

Because of a lack of explicit authorship No explicit authorship =

No credit, no reward

Previous effortsSocial rewarding techniquesAuthorship on non-MediaWiki-based systemsSemantic Web technologies

To increase community creation,AuthorReward was developed

Features contribution quantification and explicit authorship

Algorithms

AuthorReward is an extension to

MediaWiki

Page 15: Author reward

Wiki Page Collection of data on a specific subject Multiple researchers collaborate to edit

Page 16: Author reward

Contribution Score

- edit distance or Levenshtein distance

– scale factor

factors edit quality as well as edit quantity

Page 17: Author reward

Quality and Quantity

- Edit distance between and

- Whether the edit persists compared to the last version

Page 18: Author reward

We can express as

Thus, is not easily gamed

Page 19: Author reward

Score of researcher

- set of versions contributed by researcher r

Score - The sum over all contributed versions

Page 20: Author reward

Total contribution of researcher

- set of pges in which researcher provides edits

The sum of multiple contribution scores in all participated pages

Conclusion

Page 24: Author reward

AuthorReward provides bio-wikis with an authorship metric, featuring robust

contribution quantification and automated explicit authorship.

Page 25: Author reward

AuthorReward can be used in combination withSemantic web technologiesSocial rewarding techniques

Page 26: Author reward

AuthorReward provides a standard practice to reward community-curated

efforts in bio-wikis and also other domain wikis.
