We tested a linguistically motivated rule- based system in the Cancer Genetics task of the BioNLP13 shared task challenge. The performance of the system was very moderate, ranging from 52% against the development set to 45% against the test set. Interestingly, the performance of the system did not change appreciably when using only entities tagged by the inbuilt tagger as compared to performance using the gold-tagged entities. The lack of an event anaphoric module, as well as prob- lems in reducing events generated by a large trigger class to the task-specific event subset, were likely major contribut- ory factors to the rather moderate per- formance.
