Using a Distributional Neighbourhood Graph to Enrich Semantic Frames in the Field of the Environment

Gabriel Bernier-Colborne, Marie-Claude L'Homme
2015 International Conference on Terminology and Artificial Intelligence  
Results show that most lexical units identified using this method can in fact be assigned to frames related to the field of the environment.  ...  The method employs a distributional neighbourhood graph, in which each word is connected to its nearest neighbours according to a distributional semantic model.  ...  Acknowledgments This work was supported by the Social Sciences and Humanities Research Council (SSHRC) of Canada.  ...

Kunyu Peng, Juncong Fei, Kailun Yang, Alina Roitberg, Jiaming Zhang, Frank Bieder, Philipp Heidenreich, Christoph Stiller, Rainer Stiefelhagen
2022 arXiv   pre-print
At the heart of all automated driving systems is the ability to sense the surroundings, e.g., through semantic segmentation of LiDAR sequences, which experienced a remarkable progress due to the release  ...  In this paper, we introduce MASS - a Multi-Attentional Semantic Segmentation model specifically built for dense top-view understanding of the driving scenes.  ...  Farthest Point Selection (FPS) is leveraged to generate the key-node set in a highlevel representation whose information is used to enrich the information of other pillar-level nodes utilizing graph convolution  ...

Fast hybrid relocation in large scale metric-topologic-semantic map

Romain Drouilly, Patrick Rives, Benoit Morisset
2014 2014 IEEE/RSJ International Conference on Intelligent Robots and Systems  
We combine the discriminative power of semantics with the robustness of an interpretation tree to compare the graphs very fast and outperform state-of-the-art-techniques.  ...  It consists of local sub-maps connected through two topological layers at metric and semantic levels. Semantic information is used to build concise local graph-based descriptions of sub-maps.  ...  Algorithm 1 1 Details of our Interpretation Tree algorithm used to compare semantic graphs INPUTS: G 1 , G 2 : graphs of the current view and a given view in the database OUTPUTS: Score of the matching  ...

Ocelet: Simulating processes of landscape changes using interaction graphs

P. Degenne, D. Lo Seen
2016 SoftwareX  
It is characterised by the use of interaction graphs (graphs with interaction functions on their edges) to represent the system as composed of processes, each involving several entities distributed in  ...  Entities are the vertices of the graphs, and interactions are the edges on which (interaction) functions can be applied to make the system change through time.  ...  We also thank two anonymous reviewers whose comments have helped improve the paper.  ...

Dual characterizations for finite lattices via correspondence theory for monotone modal logic [article]

2014 arXiv   pre-print
Indeed, we adapt the correspondence algorithm ALBA to the setting of monotone modal logic, and we use a certain duality-induced encoding of finite lattices as monotone neighbourhood frames to translate  ...  We establish a formal connection between algorithmic correspondence theory and certain dual characterization results for finite lattices, similar to Nation's characterization of a hierarchy of pseudovarieties  ...  The adapted ALBA is semantically justified in the general environment of two-sorted frames (cf.  ...

Unsupervised human activity analysis for intelligent mobile robots

Paul Duckworth, David C. Hogg, Anthony G. Cohn
2019 Artificial Intelligence  
Analogously to information retrieval on text corpora we use generative probabilistic techniques to recover latent, semantically meaningful, concepts in the encoded observations in an unsupervised manner  ...  This is performed using a number of qualitative spatial-temporal representations which capture different aspects of the relations between the human subject and the objects in the environment.  ...  The key difference to our framework is that these works use video sequences collected from static cameras with a fixed frame of reference and a wide field of view.  ...

On Integrating Social and Sensor Networks for Emergency Management [chapter]

Farshad Shams, Antonio Cerone, Rocco De Nicola
2015 Lecture Notes in Computer Science  
The 2010 earthquake in Haiti is often referred to as the turning point that changed the way social media can be used during disasters.  ...  In this position paper, we present a review of existing disaster management systems and their underlying strategies and technologies, and identify the limitations of the tools in which they are implemented  ...  The resulting graph based semantic network can be stored as either a multi dimensional table or an RDF file.  ...

Pervasive ecosystems

Mirko Viroli, Danilo Pianini, Sara Montagna, Graeme Stevenson
2012 Proceedings of the 27th Annual ACM Symposium on Applied Computing - SAC '12  
We introduce the concept of a pervasive ecosystem, and present the coordination approach grounded upon it, which revolves around (i) the notion of a distributed and dynamic space of "live semantic annotations  ...  " (wrapping data, knowledge, and activities of humans, devices, and services) and (ii) a set of chemical-resembling coordination rules that are applied to such annotations semantically.  ...  Acknowledgments This work has been supported by the EU FP7 project "SAPERE -Self-aware Pervasive Service Ecosystems" under contract No. 256873.  ...

Improving Human-Semantic Web Interaction: The Rhizomer Experience

Roberto García, Rosa Gil
2006 Semantic Web Applications and Perspectives  
The user interface is fed by a metadata storage abstraction layer, which offers a SPARQL endpoint and implements the DESCRIBE SPARQL primitive in order to improve the usability of the resulting metadata  ...  For end-users, it looks like the web pages they are used to deal with. However, the semantics that lay behind are used to improve the user experience through an AJAX-enhanced web interface.  ...  The graph model might be useful for the user in some very specific scenario, e.g. in order to get a quick view of how some data is distributed, but even this is not usually the case for Semantic Web data  ...
