Retrofitting Word Representations for Unsupervised Sense Aware Word Similarities (L18-1)
Copied to clipboard
| Challenge: | Standard word embeddings lack the ability to distinguish senses of a word by projecting them to exactly one vector. |
| Approach: | They propose to retrofit standard word embeddings to produce sense-aware embeddable vectors using external resources as sense inventories. |
| Outcome: | The proposed method improves word similarity and relatedness scores on multiple word embeddings and established word similarities, sometimes up to an impressive margin of +0.15 Spearman correlation score. |
Hierarchical Multi-label Classification of Text with Capsule Networks (P19-2)
Copied to clipboard
| Challenge: | In hierarchical multi-label classification, samples are classified into one or multiple class labels organized in a structured label hierarchy. |
| Approach: | They apply and compare shallow capsule networks for hierarchical multi-label text classification and introduce a new real-world scenario dataset. |
| Outcome: | The proposed model outperforms neural networks and non-neural network architectures on a real-world scenario dataset. |
LT Expertfinder: An Evaluation Framework for Expert Finding Methods (N19-4)
Copied to clipboard
| Challenge: | LT Expertfinder is a web-based tool for expert finding and expert profiling. |
| Approach: | They propose a web-application that enables qualitative comparison between different ranking methods . LT Expertfinder provides detailed expert profiles linked to Wikidata and Google Scholar . |
| Outcome: | The LT Expertfinder is a web-based tool for expert finding and evaluation. |

| Challenge: | Existing methods of disambiguation of word senses are based on knowledge bases, taxonomies, and other externally built resources. |
| Approach: | They propose a method that takes a pre-trained word embedding model and induces a fully-fledged word sense inventory for 158 languages. |
| Outcome: | The proposed model is based on a pre-trained word embedding model and induces a fully-fledged word sense inventory in 158 languages. |
