Scalable Visualisation of Sentiment and Stance (L18-1)
Copied to clipboard
| Challenge: | a novel visualisation approach for sentiment and stance analysis is proposed for large datasets. |
| Approach: | They propose a visualisation approach for scalable visualisation of sentiment and stance from large-scale data. |
| Outcome: | The proposed visualisation approach can be used on a 9,278 user comments with stance explicitly declared by the author. |
Crowdsourcing and Aggregating Nested Markable Annotations (P19-1)
Copied to clipboard
| Challenge: | Existing methods for identifying markables for coreference annotation are task and language-independent and can be used for a variety of other annotation tasks. |
| Approach: | They propose a method for identifying markables for coreference annotation that combines automatic markable detectors with checking with a Game-With-A-Purpose (GWAP) and aggregation using a Bayesian annotation model. |
| Outcome: | The proposed method improves mention boundaries on news and other genres by over seven percentage points compared with state-of-the-art, domain-independent automatic mention detectors and almost three points over an in-domain mention detector. |
A Probabilistic Annotation Model for Crowdsourcing Coreference (D18-1)
Copied to clipboard
| Challenge: | Existing methods to generate annotated corpora for coreference are expensive and limited. |
| Approach: | They propose a model of annotation for aggregating crowdsourced anaphoric annotations. |
| Outcome: | The proposed model can extract from crowdsourced annotations coreference chains comparable to those obtained with expert annotation. |

| Challenge: | Existing approaches to scale up anaphoric annotation have not overcome these limitations. |
| Approach: | They propose to use a game-with-a-purpose to ‘complete’ markable annotations by using an anaphoric resolver and an aggregation method for anaphorism. |
| Outcome: | The proposed method could be adopted to greatly speed up annotation time in other projects involving games-with-a-purpose. |
A Crowdsourced Corpus of Multiple Judgments and Disagreement on Anaphoric Interpretation (N19-1)
Copied to clipboard
| Challenge: | a corpus of anaphoric information (coreference) is crowdsourced through a game-with-a-purpose . its main feature is the large number of judgments per markable: 20 on average, and over 2.2M in total. |
| Approach: | They propose to crowdsource anaphoric information corpus by a game-with-a-purpose and to use it to train a coreference resolver. |
| Outcome: | The proposed corpus contains annotations for 108,000 markables and 20 judgments per markable, and 2.2M in total. |
