WebHá 1 dia · Abstract. Open relation extraction (OpenRE) aims to extract novel relation types from open-domain corpora, which plays an important role in completing the relation schemes of knowledge bases (KBs). Most OpenRE methods cast different relation types in isolation without considering their hierarchical dependency. We argue that OpenRE is inherently ... WebMost short line segments are retained in the image at the bottom of the hierarchy, but some non-road segments are also retained. Hence, line images in the hierarchy complement each other, and thus they can be combined to yield a more reliable road network from images. 3.2 Hierarchical Grouping of Line Images
