| Challenge: | Existing gender prediction models rely on lexical and social network features to capture style beyond topic. |
| Approach: | They propose an alternative to lexical bleaching, i.e., transforming lexicals into more abstract features. |
| Outcome: | The proposed model performs similar to lexical models, but is less language-, topic-, and platform dependent. |

Neural Factor Graph Models for Cross-lingual Morphological Tagging (P18-1)
Copied to clipboard
