Summary
Data loss in Semantic Web of Things (SWoT) perception layers is tackled by a new Compressive Sensing method. This approach recovers and estimates sensory data effectively, outperforming existing techniques.
Area of Science:
- Computer Science
- Electrical Engineering
- Information Technology
Background:
- The Internet of Things (IoT) is rapidly evolving across various sectors, including industry, e-health, and education.
- Semantic Web of Things (SWoT) enhances IoT by enabling intelligent communication through a 7-layered architecture.
- The perception layer in SWoT is crucial for data collection but is prone to data loss due to resource limitations, link instability, and noise.
Purpose of the Study:
- To identify and address the challenges of data acquisition and loss in SWoT perception layers.
- To introduce a novel framework for data recovery and estimation in SWoT.
- To reduce data volume while maintaining accuracy.
Main Methods:
- A Compressive Sensing (CS) based framework is proposed for SWoT.
- The method leverages low-rank structures for accurate data recovery.
- Data estimation techniques are employed to reduce data volume.
Main Results:
- The proposed Compressive Sensing based Data Recoverability and Estimation (CS-RE) method demonstrates significant improvements.
- CS-RE outperforms existing reconstruction methods in terms of error ratio.
- The method achieves high accuracy in data recoverability on real sensory datasets.
Conclusions:
- The CS-RE method effectively addresses data loss issues in SWoT perception layers.
- The proposed framework offers a robust solution for reliable data acquisition and management in SWoT.
- This work contributes to enhancing the performance and reliability of SWoT systems.

Perception
797
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Introducing Social Perception
152
Perceiving others accurately is fundamental to effective communication and relationship-building. Social perception, a key concept in social psychology, refers to the cognitive processes through which individuals gather and interpret information about others to understand their actions, intentions, and motivations. This process extends beyond spoken words and overt behaviors, incorporating subtle nonverbal cues and contextual factors.Nonverbal Cues and Their SignificanceNonverbal cues play a...

Stereotype Content Model
15.1K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Perceptual Constancy
916
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Retrieval
269
Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

Sensory Perception: Organization of the Somatosensory System
10.3K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...
