We have made considerable progress this year on creating cross-products for GO terms. The first set of cross-products, between regulatory processes and regulated processes or functions, were added to the GO file at the beginning of 2010. Subsequently, two further sets have been added: biological processes involved in other biological processes, and cellular components that are part of other cellular components.

As a result of these changes, we have been able to develop a tool – TermGenie – that allows users to add new GO terms that conform to a cross-product template directly to the ontologies. Terms are automatically placed correctly within the ontology, and textual definitions and synonyms are automatically generated. This tool reduces the workload for ontology editors and helps reduce human error in the ontologies.

The biggest effort this year has gone into aligning GO with the Chemical Entities of Biological Interest (CHEBI) ontology, with the aim of generating cross-products between GO and CHEBI. This work involved a 2-day meeting in September with the CHEBI ontology developers to reconcile some of the critical differences between the two ontologies. This project requires major changes to both GO and CHEBI and we hope the first CHEBI cross-products will be added to GO early in 2011.

Ontology development

Internal Cross Products

We have made considerable progress this year on creating cross-products for GO terms. The first set of cross-products, between regulatory processes and regulated processes or functions, were added to the GO file at the beginning of 2010. Subsequently, two further sets have been added: biological processes involved in other biological processes, and cellular components that are part of other cellular components.

Term Genie

As a result of these changes, we have been able to develop a tool – TermGenie – that allows users to add new GO terms that conform to a cross-product template directly to the ontologies. Terms are automatically placed correctly within the ontology, and textual definitions and synonyms are automatically generated. This tool reduces the workload for ontology editors and helps reduce human error in the ontologies.

External cross-products: CHEBI alignment

The biggest effort this year has gone into aligning GO with the Chemical Entities of Biological Interest (CHEBI) ontology, with the aim of generating cross-products between GO and CHEBI. This work involved a 2-day meeting in July with the CHEBI ontology developers to reconcile some of the critical differences between the two ontologies. This project requires major changes to both GO and CHEBI and we hope the first CHEBI cross-products will be added to GO early in 2011. We have finished a first draft of a paper on this project to go to Nature Chemical Biology.

OBO Foundry

We are active members of the OBO Foundry and earlier this year GO became one of the founder set of OBO Foundry ontologies, having undergone peer review and found to meet the agreed OBO Foundry standards.

Function-Process links

We continued to make relationships between the function and process ontologies - links between the transporters and transport terms were completed in June.

Mappings

In 2010, over 1500 enzyme reactions in GO were synchronized with MetaCyc, KEGG, RHEA and EC. The reaction text was converted to reflect ChEBI names.

GO slims

A new version of the generic (non-species specific) GO slim was developed this year, a draft is currently available.

Taxon Triggers

The taxon trigger file is a set of taxonomic restrictions for specific GO terms that is used for automatic quality control of annotations. The file resides in cvs and is edited as new restrictions are made. A paper on this project has recently been published in BMC Bioinformatics.

Transcription

A major overhaul of the transcription process and function terms was made this year. This project involved one curator attending the Gene Transcription in Yeast meeting in Sant Feliu de Guixols in Spain in late June, to obtain expert input. Several rounds of changes have been made to the ontologies so far, and we expect the project to be completed by the end of the year.

The GO signaling working group is working to expand and improve the signaling terms in GO. At the start of 2010, signaling terms in the process ontology were restructured to include different types and mechanisms of signaling, and to connect the signaling pathways with the processes they regulate. We are currently standardising these terms to ensure more consistent annotation, and have begun to refine the signaling terms in the function ontology.
