Modeling Financial Analysts’ Decision Making via the Pragmatics and Semantics of Earnings Calls (P19-1)
Copied to clipboard
| Challenge: | Existing studies show earnings calls influence investor sentiment and influence investor opinions in the short term. |
| Approach: | They identify 20 pragmatic features of analysts’ questions which correlate with analysts’ pre-call investor recommendations. |
| Outcome: | The proposed model shows that earnings calls are moderately predictive of analysts’ decisions even though these decisions are influenced by market conditions and private communications. |
A Preliminary Exploration of GANs for Keyphrase Generation (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing studies on extractive keyphrases have shown promising results, but the results suggest that there is room for improvement. |
| Approach: | They propose a new keyphrase generation approach using Generative Adversarial Networks (GANs) their model produces a sequence of keyphrases and a discriminator distinguishes between human-curated and machine-generated keyphrase. |
| Outcome: | The proposed model outperforms the state-of-the-art generative models on benchmark datasets and is comparable to the best performing extractive models. |

| Challenge: | Using a new corpus of sentences from Hindi short stories, we analyze the annotations for five different discourse modes argumentative, narrative, descriptive, dialogic and informative. |
| Approach: | They propose to annotate sentences from Hindi short stories for five different discourse modes argumentative, narrative, descriptive, dialogic and informative. |
| Outcome: | The proposed corpus has a high inter-annotator agreement (0.87 k-alpha) and is able to capture the nuances of the embedded discourse structures. |

| Challenge: | Existing studies on NLP models focus on high resource languages like English, but there are only two datasets for Hindi. |
| Approach: | They propose a novel two-step classification method which uses textual-entailment predictions for classification task. |
| Outcome: | The proposed method improves classification performance by using a joint-objective for classification and textual entailment. |
