Re: Trip Reports on Dagstuhl Seminar on Knowledge Graphs

Joshua

thanks for the opportunity to clarify and apologies for the brashness
of my remarks

I did not mean that they KGs are not a type of KR, which arguably they are

but they do not satisfy KR adequacy criteria in many ways (I ll address
that more extensively
in an article) and come with limitations, an example linked below

The  lack of acknowledgment of such limitations is *startling *for me,  and
shows superficiality given that the workshop participants are leading
researchers and colleagues, and include best of the sw researchers crop
otherwise in many ways


PDM

this article explains some of the issues with KG, and especially using
KGs as sole KR methods

https://www.aclweb.org/anthology/D17-1184
  Unfortunately, information extraction approaches for KG construction must
overcome complex, unreliable, and incomplete data. Many machine learning
methods have been proposed to address the challenge of cleaning and
completing KGs. One popular class of methods learn embeddings that
translate entities and relationships into a latent subspace, then use this
latent representation to derive additional, unobserved facts and score
existing facts (Bordes et al., 2013; Wang et al., 2014; Lin et al., 2015)
