Improving Word Embeddings Using Kernel PCA

no code implementations WS 2019 Vishwani Gupta, Sven Giesselbach, Stefan R{\"u}ping, Christian Bauckhage

Word-based embedding approaches such as Word2Vec capture the meaning of words and relations between them, particularly well when trained with large text collections; however, they fail to do so with small datasets.

Making Efficient Use of a Domain Expert's Time in Relation Extraction

no code implementations12 Jul 2018 Linara Adilova, Sven Giesselbach, Stefan Rüping

In this paper, we report on an alternative approach where we first construct a relation extraction model using distant supervision, and only later make use of a domain expert to refine the results.
