RETA : A Schema-Aware, End-to-End Solution for Instance Completion in Knowledge Graphs

Rosso, Paolo ; Yang, Dingqi ; Ostapuk, Natalia ; Cudré-Mauroux, Philippe

In: The Web Conference 2021, Ljubljana, Slovenia, April 12-23, 2021, 2021, p. 1-12

Knowledge Graph (KG) completion has been widely studied to tackle the incompleteness issue (i.e., missing facts) in modern KGs. A fact in a KG is represented as a triplet (ℎ, 𝑟, 𝑡 ) linking two entities ℎ and 𝑡 via a relation 𝑟 . Existing work mostly consider link prediction to solve this problem, i.e., given two elements of a triplet predicting the missing one, such as (ℎ,...

Biodiversity effects on grape quality depend on variety and management intensity

Steiner, Magdalena ; Grace, James B. ; Bacher, Sven

In: Journal of Applied Ecology, 2021, p. 1-13

1. Interactions between plants can be beneficial, detrimental or neutral. In agricultural systems, competition between crop and spontaneous vegetation is a major concern. We evaluated the relative support for three non-exclusive ecological hypotheses about interactions between crop and spontaneous plants based on competition, complementarity or facilitation. 2. The study was conducted in...

Sampbias, a method for quantifying geographic sampling biases in species distribution data

Zizka, Alexander ; Antonelli, Alexandre ; Silvestro, Daniele

In: Ecography, 2020/n/a/n/a/-

Geo-referenced species occurrences from public databases have become essential to biodiversity research and conservation. However, geographical biases are widely recognized as a factor limiting the usefulness of such data for understanding species diversity and distribution. In particular, differences in sampling intensity across a landscape due to differences in human accessibility are...
