RiceWiki: A Wiki-Based Database for Community Curation of Rice Genes

Rice is the most important staple food for a large part of the world's human population and also a key model organism for biological studies of crops as well as other related plants. Here we present RiceWiki (, a wiki-based, publicly editable and open-content platform for community curation of rice genes. Most existing related biological databases are based on expert curation; with the exponentially exploding volume of rice knowledge and other relevant data, however, expert curation becomes increasingly laborious and time-consuming to keep knowledge up-to-date, accurate and comprehensive, struggling with the flood of data and requiring a large number of people getting involved in rice knowledge curation. Unlike extant relevant databases, RiceWiki features harnessing collective intelligence in community curation of rice genes, quantifying users' contributions in each curated gene and providing explicit authorship for each contributor in any given gene, with the aim to exploit the full potential of the scientific community for rice knowledge curation. Based on community curation, RiceWiki bears the potential to make it possible to build a rice encyclopedia by and for the scientific community that harnesses community intelligence for collaborative knowledge curation, covers all aspects of biological knowledge and keeps evolving with novel knowledge.

Screenshots of the RiceWiki page for the rice semidwarf-1 (sd1) gene, available at This gene was collaboratively curated by nine researchers, yielding 89 versions as of 1 August 2013. (A) Whole page, containing multiple different sections. (B) Brief authorship information in reward for community curation and a one-sentence summary for description of this gene. (C) Annotated information. It is organized as free text and contains several sub-sections. (D) Labs working on this gene. It is a list of laboratories working on this gene derived from references and provided by the community. (E) References, which are automatically generated and formatted with the help of the ‘Cite’ extension. (F) Structured information. It is organized structurally in the form of a table, including gene symbol, gene description, sequence information, gene structure, etc. (G) Authorship details generated by the ‘AuthorReward’ extension that quantifies researchers’ contributions and provides explicit authorship according to their quantitative contributions. The cutoff score for awarding authorship is configurable and set to 1 (by default) in RiceWiki.
