Integrated semantically guided spatial fragmentation and biomorphological forest segmentation using terrestrial laser scanning data: layer-wise dynamic connectivity features as the key factor in stem structure reconstruction accuracy

The separation of a forest plot into individual trees and the automatic extraction of their stem structures from terrestrial laser scanning data are complicated by dense stands, occlusions, and the diversity of biomorphological forms. Existing algorithms usually solve scene partitioning, voxel classification, and tree...

Structure-aware retrieval methods for web table fragments in question-answering systems: a scientific analytical review

It is shown that dense and structure-aware whole-table methods dominate, whereas scalable retrieval of rows, cells, subtables, and multi-table evidence remains insufficiently developed, and further research should focus on multivector methods that preserve local table structure while maintaining acceptable computationa...
