| Evaluation Setup | As mentioned in Section 4, the only learned parameters in our model are those associated with the sequence labeling factor ngEQ. |
| Model | 4.1 Sequence Labeling Factor |
| Model | The sequence labeling factor is similar to a standard sequence CRF (Lafferty et al., 2001), Where the potential over a message label sequence decomposes |
| Problem Formulation | Message Labels (3/): We assume that each message has a sequence labeling , where the labels consist of the record fields (e.g., ARTIST and VENUE) as well as a NONE label denoting the token does not correspond to any domain field. |
