Semantic Mapping for Autonomous Subsea Intervention [PDF]
Sensors, 2021 This paper presents a method to build a semantic map to assist an underwater vehicle-manipulator system in performing intervention tasks autonomously in a submerged man-made pipe structure. The method is based on the integration of feature-based simultaneous localization and mapping (SLAM) and 3D object recognition using a database of a priori known ...

Linguistic Typology, 2013 Abstract Semantic maps are a means of representing universal structure underlying semantic variation. However, no algorithm has existed for inferring a graph-based semantic map from cross-language data. Here, we note that this open problem is formally identical to the known problem of inferring a social network from disease outbreaks ...

A Computationally Efficient Semantic SLAM Solution for Dynamic Scenes
Remote Sensing, 2019 In various dynamic scenes, there are moveable objects such as pedestrians, which may challenge simultaneous localization and mapping (SLAM) algorithms. Consequently, the localization accuracy may be degraded, and a moving object may negatively impact the

Efficiently learning metric and topological maps with autonomous service robots [PDF]
, 2007 Models of the environment are needed for a wide range of robotic applications, from search and rescue to automated vacuum cleaning. Learning maps has therefore been a major research focus in the robotics community over the last decades.

Fusion of aerial images and sensor data from a ground vehicle for improved semantic mapping [PDF]
, 2007 This work investigates the use of semantic information to link ground level occupancy maps and aerial images. A ground level semantic map, which shows open ground and indicates the probability of cells being occupied by walls of buildings, is obtained by

Frontiers in Communication, 2021 The goal of this paper is to offer an overview of polysemy patterns in Mandarin’s chief spatial categories: prepositions (e.g., zai) and simple and compound localisers (respectively, qian and qian-mian).

Survey over Existing Query and Transformation Languages [PDF]
, 2004 A widely acknowledged obstacle for realizing the vision of the Semantic Web is the inability of many current Semantic Web approaches to cope with data available in such diverging representation formalisms as XML, RDF, or Topic Maps.

Semantic maps and mental representation
Linguistic Discovery, 2010 Semantic maps are usually assumed to describe a universal arrangement of different conceptual situations in a speaker's mind as determined by perceived relations of similarity between these conceptual situations. This paper provides a number of arguments

A Semantic Information-Based Optimized vSLAM in Indoor Dynamic Environments
Applied Sciences, 2023 In unknown environments, mobile robots can use visual-based Simultaneous Localization and Mapping (vSLAM) to complete positioning tasks while building sparse feature maps and dense maps.
