We have developed a challenge task for the second BioCreAtIvE (Critical Assessment of Information Extraction in Biology) that requires participating systems to provide lists of the EntrezGene (formerly LocusLink) identifiers for all human genes and proteins mentioned in a MEDLINE abstract. We are distributing 281 annotated abstracts and another 5,000 noisily annotated abstracts along with a gene name lexicon to participants. We have performed a series of baseline experiments to better characterize this dataset and form a foundation for participant exploration.
The first Critical Assessment of Information Extraction in Biology's (BioCreAtIvE) Task 1B involved linking mentions of model organism genes and proteins in MEDLINE abstracts to their corresponding identifiers in three different model organism databases (MGD, SGD, and FlyBase). The task is described in some detail in , along with descriptions of many different approaches to the task in the same journal issue. There has been quite a bit of past work associating text mentions of human genes and proteins with unique identifiers including the early work by Cohen et al.  and the AZURE system . Very recently, Fang et al.  reported excellent results on a data set they created using one hundred MEDLINE abstracts. This widespread community interest in the issue and our experience with the first BioCreAtIvE motivated us to prepare another evaluation task for inclusion in the second BioCreAtIvE . This task will require systems to link mentions of human genes and proteins with their corresponding EntrezGene (LocusLink) identifiers. We hope that researchers in this area can use this data set to compare techniques and gauge performance gains. It can also be used to address issues in the general portability of normalization techniques and to investigate the relationships between co-mentioned genes and proteins.
It is interesting to compare this new corpus with Task 1B of BioCreAtIvE 1 for insights into portability of normalization techniques. …
Vlachos et al. observed , in biomedical text there is a high occurrence of families of genes and proteins being mentioned by a single term such as: "Mxi1" belongs to the Mad (Mxi1) family of proteins, which function as potent antagonists of Myc oncoproteins". In future work in biomedical entity normalization, we suggest that normalizing entity mentions to family mentions may be an effective way to support other biomedical text mining tasks. Possibly the protein families in InterPro  could be used as normalization targets for mentions of families. For example, the mention of "Myc oncoproteins" could link to InterPro:IPR002418. This would enable information extraction systems that extract facts (relations, attributes) on gene families to attach those properties to all family members.
In summary, we have described the motivation and development of a dataset for evaluating the automatic mapping of the mention of human genes/proteins to unique identifiers, which will be used as part of the second BioCreAtIvE. We have elucidated some of the properties of this data set, and made some suggestions about how it may be used in conjunction with biological knowledge to investigate the properties of co-mentioned genes and proteins. Anonymized submissions by evaluation participants along with the evaluation set gold standard annotations will be made publicly available  after the workshop, tentatively scheduled for the spring of 2007.
