3. Methods and strategies for annotation

a. Literature curation: We continue to put most of our annotation effort (95%) into annotation of gene products from the literature.

b. Computational annotation strategies: With every genome release, we run two computational GO annotation pipelines, one based on INTERPROtoGO mapping and the other based on a TargetP analysis. These results are integrated into our GO annotation file. This represents roughly 5% of our annotation effort.

c. Integration of non-TAIR Arabidopsis annotations: We integrate GOA Arabidopsis GO annotations into our gene association file so that all Arabidopsis annotations, regardless of original source, are now relayed to GO via TAIR with the appropriate source attribution. The following types of annotations are included in our Arabidopsis gene association file:

 1. Literature-based annotations made by TAIR curators
 2. Community annotations made via TAIR's TOAST annotation tool (see below)
 3. GOA annotations for Arabidopsis with experimental evidence codes
 4. PAINT-based Arabidopsis annotations from RefGenome group
 5. Function-Process link-based annotations from GOC 
 6. TIGR's annotations from Arabidopsis functional annotation project

d. Priorities for annotation:

 1. literature describing the characterization of previously undescribed ('novel') genes, 
 2. genes that do not have any GO annotations at all (none of the three aspects),
 3. recent literature from high impact factor journals

e. Review of user-submitted annotations (see TOAST section below)

 Donghui and Tanya review the annotations submitted via TOAST, making sure that terms were mapped correctly and that the 
 proper evidence_with information is entered, if necessary.  Sometimes, follow-up with the submitter via email is necessary.

4. Presentations and publications

Talks - GO-related but not primarily about GO

Donghui Li, From experimental data to structured knowledge: Literature curation workflow at The Arabidopsis Information Resource. 5th International Biocuration Conference (BioCreative), Washington, DC, USA, April 2-4, 2012.

5. Other Highlights

A. Ontology Development Contributions

  • GO terms contributed by TAIR

Donghui Li has submitted term requests involving 46 GO terms via SourceForge and TermGenie on behalf of TAIR curators from November 2011 to November 2012.

  • Other ontology development work

Tanya Berardini:

  • continues to participate in creating cross-products for terms within and among the three GO namespaces
  • participated in LEGO prototyping and modeling
  • participated in the project to align GO with ChEBI
  • working on aligning the Plant Ontology (PO) with GO with respect to anatomical structures used in the development branch of the biological process ontology
  • participates in the rota for Sourceforge request (4 total people in rota, one week at a time, weekly conference call)
  • participates in the rota for the gatekeeper for the TermGenie requests (4 total people in rota, one week at a time)
  • attends weekly GO editors conference call

Donghui Li:

  • attends regular GO annotation conference calls as the TAIR representative

B. Annotation outreach and user advocacy efforts

  • PAINT annotation

Donghui Li does PAINT-based annotation.

  • TOAST (TAIR Online Annotation Submission Tool)

TAIR continues to collect controlled vocabulary annotations via its online tool. TOAST

TAIR can accept annotations based on any journal article, regardless of the journal it was published in, provided that the article has a DOI or a PMID. Submitters must be registered at TAIR.

  • GO help

Tanya Berardini continues to participate in manning the GO helpdesk. This involves answering the questions that come in through gohelp@geneontology.org or forwarding them to the appropriate parties for response. There are 8 GOC curators that rotate this task, one week at a time.

C. Other highlights

Donghui Li continues to serve as a member of the BioCreative User Advisory Group. This involves developing a GO task for BioCreative V (development of modules to aid GO curators in identifying articles with curatable GO information (triage) and extracting gene function terms and the associated evidence sentences in full-length articles) as well as a strategy to create a gold-standard annotated literature corpus for text mining.
