N2 - The paper presents an iterative approach to understanding semi-structured or unstructured tabular data with pharmaceutical records. Thetask is to split records with entities such as drug name, dosage strength,dosage form, and package size into the appropriate columns. The data isprovided by many suppliers, and so it is very diverse in terms of structure.Some of the records are easy to parse using regular expressions; othersare difficult and need advanced methods. We used regular expressionsfor the easy-to-parse data and conditional random fields for the morecomplex records. We iteratively extend the training data set using theabove methods together with manual corrections. Currently, the F1 scorefor correct classification into 5 classes is 95%.
