-Early Gains Matter: A Case for Preferring Generative over Discriminative Crowdsourcing Models 
-* Paul Felt, Eric Ringger, Kevin Seppi, Robbie Haertel 
-* '''​To appear in NAACL 2015'''​ 
-* Crowdsourcing models aggregate multiple fallible human judgments. Previous work largely takes a discriminative modeling approach. This paper demonstrates that a data-aware crowdsourcing model incorporating a generative multinomial data model enjoys a strong competitive advantage over its discriminative log-linear counterpart in the typical crowdsourcing setting.  ​

 +| :::                             | Machine assistance is vital to managing the cost of corpus annotation projects. Identifying effective forms of machine assistance through principled evaluation is particularly important and challenging in under-resourced domains and highly heterogeneous corpora, as the quality of machine assistance varies. We perform a fine-grained evaluation of two machine-assistance techniques in the context of an under-resourced corpus annotation project. This evaluation requires a carefully controlled user study crafted to test a number of specific hypotheses. We show that human annotators performing morphological analysis of text in a Semitic language perform their task significantly more accurately and quickly when even mediocre pre-annotations are provided. When pre-annotations are at least 70% accurate, annotator speed and accuracy show statistically significant relative improvements of 25–35 and 5–7%, respectively. However, controlled user studies are too costly to be suitable for under-resourced corpus annotation projects. Thus, we also present an alternative analysis methodology that models the data as a combination of latent variables in a Bayesian framework. We show that modeling the effects of interesting confounding factors can generate useful insights. In particular, correction propagation appears to be most effective for our task when implemented with minimal user involvement. More importantly,​ by explicitly accounting for confounding variables, this approach has the potential to yield finegrained evaluations using data collected in a natural environment outside of costly controlled user studies. |

-==Want to help?== 
  
-We are currently annotating a corpus of English news articles. ​ You can help by taking the time to annotate a set of sentences. ​ You will be presented with one sentence at a time and will be asked to either annotate a single word or the entire sentence. ​ We are ready for user help.  We expect that the average participant will spend less than an hour on the task.  Thank you in advance for participating!
