Fact verification aims to evaluate the authenticity of a given claim based on evidence sentences retrieved from Wikipedia articles. Existing works mainly leverage natural language inference methods model semantic interaction and evidence, or further employ graph structure capture relation features between multiple evidences. However, previous have limited representation ability in encoding comp...

Abstract The scarce evidence of paleontological records between the upper Permian and Anisian (Middle Triassic) Western Europe could reflect (1) large stratigraphic gaps in continental successions and/or (2) persistence disturbed conditions after Permian–Triassic Boundary extinction event succession ecological crises that occurred during Early Triassic. In this context, study palynological asso...

Aiming at the counterintuitive phenomena of the Dempster–Shafer method in combining the highly conflictive evidences, a combination method of evidences based on the clustering analysis is proposed in this paper. At first, the cause of conflicts is disclosed from the point of view of the internal and external contradiction. And then, a new similarity measure based on it is proposed by comprehens...

The perforated Pediastrum Meyen s.l. species are recorded for the first time in basal levels of Tithonian Vaca Muerta Formation, extending its stratigraphical record to ages as old Late Jurassic times. Based on ecological requirements simplex var. clathratum and P. biwaense, previously warm paleoclimatic conditions suggested by Neuquén Basin, reinforced. co-occurrence different mechanisms that ...
