Query: RelSifter: Scoring Triples from Type-like Relations - The Samphire
  Triple Scorer at WSDM Cup 2017   We present RelSifter, a supervised learning approach to the problem of
assigning relevance scores to triples expressing type-like relations such as
'profession' and 'nationality.' To provide additional contextual information
about individuals and relations we supplement the data provided as part of the
WSDM 2017 Triple Score contest with Wikidata and DBpedia, two large-scale
knowledge graphs (KG). Our hypothesis is that any type relation, i.e., a
specific profession like 'actor' or 'scientist,' can be described by the set of
typical "activities" of people known to have that type relation. For example,
actors are known to star in movies, and scientists are known for their academic
affiliations. In a KG, this information is to be found on a properly defined
subset of the second-degree neighbors of the type relation. This form of local
information can be used as part of a learning algorithm to predict relevance
scores for new, unseen triples. When scoring 'profession' and 'nationality'
triples our experiments based on this approach result in an accuracy equal to
73% and 78%, respectively. These performance metrics are roughly equivalent or
only slightly below the state of the art prior to the present contest. This
suggests that our approach can be effective for evaluating facts, despite the
skewness in the number of facts per individual mined from KGs.
