Dealing with Uncertainty in Lexical Annotation
(Instituto de Informática - Universidade Federal do Rio Grande do Sul, 2010)
Incremental Hierarchical Clustering driven Automatic Annotations for Unifying IoT Streaming Data
In the Internet of Things (IoT), Cyber-Physical Systems (CPS), and sensor technologies huge and variety of streaming sensor data is generated. The unification of streaming sensor data is a challenging problem. Moreover, ...
Semantic Cohesion for Image Annotation and Retrieval
(Revista Computación y Sistemas; Vol. 16 No. 1, 2012-03-05)
Abstract. We present methods for image annotation and retrieval based on semantic cohesion among terms. On the one hand, we propose a region labeling technique that assigns an image the label that maximizes an estimate ...
Automatic semantic maps generation from lexical annotations
The generation of semantic environment representations is still an open problem in robotics. Most of the current proposals are based on metric representations, and incorporate semantic information in a supervised fashion. ...
SemVisM: Semantic visualizer for medical image
SemVisM is a toolbox that combines medical informatics and computer graphics tools for reducing the semantic gap between low-level features and high-level semantic concepts/terms in the images. This paper presents a novel ...
LexToMap: lexical-based topological mapping
Any robot should be provided with a proper representation of its environment in order to perform navigation and other tasks. In addition to metrical approaches, topological mapping generates graph representations in which ...
Supervised Learning Algorithms Evaluation on Recognizing
(Computación y Sistemas, 2012-08-31)
Abstract. The meaning of such verb-noun collocations as the wind blows, time flies, the day passes by can be generalized as ‘what is designated by the noun exists’. Likewise, the meaning of make a decision, provide support, ...
Tackling Hypotheticals in Helminth Genomes
Advancements in genome sequencing have led to the rapid accumulation of uncharacterized ‘hypothetical proteins’ in the public databases. Here we provide a community perspective and some best-practice approaches for the ...
