Exploiting the Structure of Background Knowledge Used in Ontology Matching. [PDF]
CEUR Workshop Proceedings, 2006 We investigate the use of a background knowledge ontology in ontology matching. We conducted experiments on matching two medical ontologies using a third extensive one as background knowledge, and compare the results with directly matching the two ontologies.

Discovering Missing Background Knowledge in Ontology Matching. [PDF]
, 2006 Semantic matching determines the mappings between the nodes of two graphs (e.g., ontologies) by computing logical relations (e.g., subsumption) holding among the nodes that correspond semantically to each other.

Cuttlefish camouflage: Blending in by matching background features [PDF]
Current Biology, 2022 Cuttlefish are masters of camouflage and show a remarkable ability to hide in plain sight. A new study reveals how these animals translate visual information about their surroundings into effective camouflage patterns.

Background knowledge in ontology matching: A survey
Semantic Web, 2022 Ontology matching is an integral part for establishing semantic interoperability. One of the main challenges within the ontology matching operation is semantic heterogeneity, i.e. modeling differences between the two ontologies that are to be integrated. The semantics within most ontologies or schemas are, however, typically incomplete because they are

Distance-dependent aposematism and camouflage in the cinnabar moth caterpillar (Tyria jacobaeae, Erebidae) [PDF]
Royal Society Open Science, 2018 Defended prey often use distinctive, conspicuous, colours to advertise their unprofitability to potential predators (aposematism). These warning signals are frequently made up of salient, high contrast, stripes which have been hypothesized to increase ...

Nocturnal camouflage through background matching against moonlight. [PDF]
Proc Natl Acad Sci U S ACamouflage is often considered a daytime phenomenon based on light and shade. Nocturnal camouflage can also occur, but its mechanistic basis remains unclear. Here, we analyze the conditions for background matching (BM) of avian predators against the night sky.

Water column use by reef fishes of different color patterns [PDF]
Neotropical Ichthyology, 2022 Color in animals responds to selective pressures and mediates the relationship between organism and environment. Reef fishes have the amplest variety of pigment cell types. This color patterns’ variety may function as camouflage and be related to spatial

Adaptive Background Matting Using Background Matching
CoRR, 2022 Due to the difficulty of solving the matting problem, lots of methods use some kinds of assistance to acquire high quality alpha matte. Green screen matting methods rely on physical equipment. Trimap-based methods take manual interactions as external input. Background-based methods require a pre-captured, static background. The methods are not flexible

Background Knowledge in Schema Matching: Strategy vs. Data [PDF]
, 2021 The use of external background knowledge can be beneficial for the task of matching schemas or ontologies automatically. In this paper, we exploit six general-purpose knowledge graphs as sources of background knowledge for the matching task. The background sources are evaluated by applying three different exploitation strategies.
