DUKweb: Diachronic word representations from the UK Web Archive corpus
This provides a valuable dataset for researchers in social studies and NLP, but it is incremental as it applies existing methods to new data.
The authors tackled the lack of publicly available diachronic word embeddings by creating DUKweb, a large-scale resource from the UK Web Archive (1996-2013), which includes co-occurrence matrices and embeddings for each year, and demonstrated its utility in a case study on word meaning change detection.
Lexical semantic change (detecting shifts in the meaning and usage of words) is an important task for social and cultural studies as well as for Natural Language Processing applications. Diachronic word embeddings (time-sensitive vector representations of words that preserve their meaning) have become the standard resource for this task. However, given the significant computational resources needed for their generation, very few resources exist that make diachronic word embeddings available to the scientific community. In this paper we present DUKweb, a set of large-scale resources designed for the diachronic analysis of contemporary English. DUKweb was created from the JISC UK Web Domain Dataset (1996-2013), a very large archive which collects resources from the Internet Archive that were hosted on domains ending in `.uk'. DUKweb consists of a series word co-occurrence matrices and two types of word embeddings for each year in the JISC UK Web Domain dataset. We show the reuse potential of DUKweb and its quality standards via a case study on word meaning change detection.
