Summary
This summary is machine-generated.This study introduces the Text-Image Semantic Relevance Identification (TISRI) model to improve aspect-based multimodal sentiment analysis (ABMSA) by addressing text-image relevance. TISRI enhances sentiment analysis accuracy for multimodal data.
Area Of Science
- Artificial Intelligence
- Natural Language Processing
- Computer Vision
Background
- Aspect-based multimodal sentiment analysis (ABMSA) identifies sentiment towards specific aspects in multimodal data.
- Existing ABMSA models often fail to account for semantic irrelevance between text and image components.
- Multimodal concatenation in current models can be suboptimal when text and image lack coherence.
Purpose Of The Study
- To propose a novel Text-Image Semantic Relevance Identification (TISRI) model for ABMSA.
- To enhance the accuracy of sentiment analysis in multimodal datasets with potentially irrelevant text-image pairs.
- To improve the robustness of ABMSA models by dynamically managing image information based on semantic relevance.
Main Methods
- Developed a multimodal feature relevance identification module to assess text-image semantic similarity.
- Implemented an image gate mechanism to dynamically control image information input.
- Integrated an attention mechanism for text-aware image representation during multimodal fusion.
- Utilized auxiliary image information to bolster visual feature representation.
Main Results
- The TISRI model demonstrated competitive performance on two ABMSA Twitter datasets.
- Experimental results validated the effectiveness of the proposed semantic relevance identification and dynamic information control methods.
- The attention-based fusion effectively prevented irrelevant image information from interfering with sentiment analysis.
Conclusions
- The TISRI model offers a significant advancement in aspect-based multimodal sentiment analysis.
- Dynamically controlling image information based on semantic relevance is crucial for improving ABMSA performance.
- The proposed approach effectively handles multimodal data where text and image may not be semantically aligned.

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...
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

In signal processing, signals are classified based on various characteristics: continuous-time versus discrete-time, periodic versus aperiodic, analog versus digital, and causal versus noncausal. Each category highlights distinct properties crucial for understanding and manipulating signals.
A continuous-time signal holds a value at every instant in time, representing information seamlessly. In contrast, a discrete-time signal holds values only at specific moments, often denoted as x(n), where...
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
The two-state receptor model explains a drug's interaction with receptors, such as G protein-coupled receptors and ligand-gated ion channels, to induce or inhibit a biological response. When no natural ligands are present, a receptor exists in an equilibrium of inactive (Ri) and active (Ra) conformations. The inactive form does not produce a response, while the active form generates a basal effect known as constitutive activity.
The binding affinity of a drug determines its interaction with...
