Modelling Uncertainty in Collaborative Document Quality Assessment

no code implementations WS 2019 Aili Shen, Daniel Beck, Bahar Salehi, Jianzhong Qi, Timothy Baldwin

In the context of document quality assessment, previous work has mainly focused on predicting the quality of a document relative to a putative gold standard, without paying attention to the subjectivity of this task.

How Well Do Embedding Models Capture Non-compositionality? A View from Multiword Expressions

no code implementations WS 2019 N, Navnita akumar, Timothy Baldwin, Bahar Salehi

In this paper, we apply various embedding methods on multiword expressions to study how well they capture the nuances of non-compositional data.

A Joint Model for Multimodal Document Quality Assessment

no code implementations4 Jan 2019 Aili Shen, Bahar Salehi, Timothy Baldwin, Jianzhong Qi

The quality of a document is affected by various factors, including grammaticality, readability, stylistics, and expertise depth, making the task of document quality assessment a complex one.

A Comparative Study of Embedding Models in Predicting the Compositionality of Multiword Expressions

no code implementations ALTA 2018 N, Navnita akumar, Bahar Salehi, Timothy Baldwin

In this paper, we perform a comparative evaluation of off-the-shelf embedding models over the task of compositionality prediction of multiword expressions(``MWEs'').
