Previous research suffers from biases, so they release a dataset for analyzing the semantic shift of synonyms over time.
Moreover, they propose two methods (unsupervised and supervised) for analyzing the semantic shift.
3. Where is the key to technologies and techniques?
3.1 Dataset
They create a dataset using Fernald's English Synonyms and Antonyms and WordNet.
They define synsets in WordNet as the "sense" of synonyms.
3.2 Unsupervised Methods
DD (Diachronic Distance): calculate distances of the same words at different time periods
SD (Synchronic Distance): calculate distances of pairs of synonyms at the same time period
In the prediction, they use a threshold (average DD or SD for all pair of words).
3.3 Supervised Methods
They use the above features to train the Logistic Regression model.
4. How did evaluate it?
From this table, it is hard to predict synonyms or not correctly.
Moreover, many methods predict most words as "Different (not synonym)".
5. Is there a discussion?
They indicate that the low performance above table is due to a previous superordinate-subordinate relationship.
