Introduction LncRNAWiki is a wiki-based, publicly editable and open-content platform for community curation of human long non-coding RNAs (lncRNAs), viz., a community-curated lncRNA knowledgebase. Unlike conventional biological databases based on expert curation, lncRNAWiki harnesses collective intelligence to collect, edit and annotate information about lncRNAs, quantifies users' contributions in each annotated lncRNA and provides explicit authorship to encourage more participation from the whole scientific community. Imagine a world in which every single person on the planet has free access to the sum of all human knowledge. — Jimmy Wales, Founder of Wikipedia Featured lncRNAs: MALAT-1, LUNAR1, HOTAIR, Xist, Air, NEAT1, Kcnq1ot1, HOTTIP, Evf2 (see more) Newly curated lncRNAs: ABALON, APOA1-AS, APTR, BANCR, BDNF-AS, BLACAT1, BPESC1, CAHM, CASC8, CCAT-1, CCAT2,CISTR, CRNDE, CYYR1-AS1, DALIR, DANCR, DBE-T, DHRS4-AS1, DLEU1, DLEU2, ERICD, ESRG, FENDRR, FIRRE,FOXCUT, FTX, GHET1, GHRLOS, GPR1-AS, HAGLR, HEIH, JADDR, KANTR, LINC-PINT, LINC00163, LINC00312, LINC00850, LINC01191, LSINCT5, LUCAT1, MIR22HG, MIR31HG, MIR99AHG, MIR100HG, MIR155HG, MIR222HG, MIG403HG, MYCNUT, NAMA, NRIR, OVAAL, PACER, PART-1, PAUPAR, PCA3, PCAT-1, PCAT4, PACT7, PRNCR1, PTCSC2, PTCSC3, PVT1, PWRN1, PWRN2, RASSF1-AS1, SCAANT1, SCHLAP1, SENCR, TARID BLAST lncRNAs: If a lncRNA is newly reported in a published paper but is not found in LncRNAWiki after BLAST, please consider to create a new page for this lncRNA to obtain its authorship in LncRNAWiki. See here for help. Community curation: Community-curated efforts are quantified and rewarded by giving explicit authorship. Please share your expertise and perform curations to have the authorship for lncRNAs of your interest.

Data sources We integrated lncRNA sequences and annotation information from three data sources: GENCODE (version 19; 23,898 human lncRNA transcripts), NONCODE (version 4.0; 95,135 human lncRNA transcripts), and LNCipedia (version 2.1; 32,181 human lncRNA transcripts). After the process of error and redundancy elimination, we at last obtained 105,255 non-redundant lncRNA transcripts. To examine how many lncRNAs have been functionally annotated, we blasted the 105,255 lncRNAs against lncRNA sequences in lncRNAdb (purple circle indicates lncRNAdb) (downloaded on 21 July, 2014; 223 lncRNAs in total) and found that only about 100 human lncRNAs have been functionally annotated to date, indicating a long-term process of human lncRNA annotation.

Classification Taking into account that the genomic context of lncRNAs may offer insights into their function, the classification of lncRNAs based on genomic location is of great biological significance in in-depth mining and analysis (Ma etal. 2013, RNA Biology). We classified lncRNAs into seven groups (Intergenic, Intronic (S),Intronic (AS),Overlapping (S),Overlapping (AS), Sense and Antisense) based on their genomic location in respect to protein-coding genes.
