| Challenge: | Language understanding for task-based dialog systems is often termed "dialog state tracking" (DST) whereas semantic parsing is the task of converting a single-turn utterance to a graphstructured meaning representation, DST is more complex. |
| Approach: | They propose a framework for dialog state tracking that incorporates semantic compositionality, cross-domain knowledge sharing and co-reference. |
| Outcome: | The proposed framework improves on state-of-the-art approaches for dialog state tracking (DST) it incorporates semantic compositionality, cross-domain knowledge sharing and co-reference. |

| Challenge: | a scalable method for estimating the noisiness of labels produced by crowdsourcing annotation tasks is developed. |
| Approach: | They propose a scalable method for estimating the noisiness of labels produced by crowdsourcing semantic annotation tasks and reducing the resulting error by 20-30%. |
| Outcome: | The proposed method reduces the error of the labeling process by 20-30% compared to other common labeling strategies. |
