Probabilistic Semantic Mapping for Autonomous Driving in Urban Environments

open access: yesSensors, 2023
Statistical learning techniques and increased computational power have facilitated the development of self-driving car technology. However, a limiting factor has been the high expense of scaling and maintaining high-definition (HD) maps. These maps are a

Extracting Semantic Information from Visual Data: A Survey

open access: yesRobotics, 2016
The traditional environment maps built by mobile robots include both metric ones and topological ones. These maps are navigation-oriented and not adequate for service robots to interact with or serve human users who normally rely on the conceptual ...

Discovering Class-Specific Pixels for Weakly-Supervised Semantic Segmentation [PDF]

open access: yes, 2017
We propose an approach to discover class-specific pixels for the weakly-supervised semantic segmentation task. We show that properly combining saliency and attention maps allows us to obtain reliable cues capable of significantly boosting the performance.

A Diachronic Dimension in Maps of Case Functions

open access: yesLinguistic Discovery, 2010
One of the advantages of classical semantic maps with distinct connections between individual meanings (or functions) is that they are well suited for the inclusion of diachronic information.

Grammaticalization and Semantic Maps: Evidence from Artificial Language

open access: yesLinguistic Discovery, 2010
Semantic maps have offered linguists an appealing and empirically rooted methodology for describing recurrent structural patterns in language development and the multifunctionality of grammatical categories.

Polysemous Qualities and Universal Networks, Invariance and Diversity

open access: yesLinguistic Discovery, 2010
The topic of this paper is the conceptual organization of polysemous prototypical qualities. This study, based on data collected in 24 languages, makes use of a single notional space composed of 110 notions.

Semantic Maps or Coding Maps? Towards a Unified Account of the Coding Degree, Coding Complexity, and Coding Distance of Coordination Relations

open access: yesLinguistic Discovery, 2010
The aim of this paper is to explore the degree to which semantic maps and conceptual spaces may comprehensively describe cross-linguistic variation by discussing the types of phenomena that may be consistently represented in a unified account.

Teaching Method for Entity–Relationship Models Based on Semantic Network Theory

open access: yesIEEE Access, 2022
Students in database courses often have difficulty learning entity–relationship (ER) modeling. According to semantic network theory, learning to construct an ER diagram for a database problem requires complex semantic transformations between the ...
