A Semantic Matching Method of E-Government Information Resources Knowledge Fusion Service Driven by User Decisions

Abstract

This study focuses on the knowledge fusion model of e-government information resources that supports user decision-making information needs, it discusses the user decision-making information needs model, the knowledge fusion service model, and the relationship between them. The inter-layer mapping matching mechanism realizes the ultimate value of knowledge fusion. Therefore, this paper analyses and studies the mapping mechanism between the user information demand model and the knowledge fusion service model. A semantic, similarity-based knowledge fusion service matching method for e-government information resources is proposed to address the problem of lack of semantics in traditional web service matching methods. This method uses the ontology description language OWL-S to map information requirement documents of user decisions and knowledge fusion service function documents into an ontology tree structure. The authors then use this as the basis to calculate the concept similarity and relationship similarity measures, and the service matching based on semantic similarity can be realized.

Design and Implementation of an Intelligent Metro Project Investment Decision Support System

“…Jemal et al (2019) addressed challenges in the dynamic control of engineering progress and cost by combining BIM technology with earned value analysis. They employed WBS task decomposition to analyze deviations between construction process cost and time, optimizing deviation adjustment measures through comparative analysis (Huang et al, 2023;Feng & Chen, 2022).…”

Exploring Eco-Innovation Barriers to the Sustainability Transition in Cold Chain E-Fulfilment Systems

“…While T1-FBWM was initially used for individual decision-making, the GDM is increasingly important in today's rapidly changing and complex decision-making environments. Decisions often involve multiple stakeholders with different perspectives, requiring balancing multiple criteria and tradeoffs (Huang et al, 2023). Therefore, in this study, the GDM-FBWM is developed to navigate such complex decision-making environments.…”

Knowledge Extraction From National Standards for Natural Resources

“…(4) The entity relationships in NSNR tend to express recommendations or constraints in semantics, such as "should" and "must". In response to the above features and challenges, designing a multi-dimension featured domain knowledge extraction method (Huang, X., 2017) which less depends on tagged corpus is of great significance for knowledge extraction from NSNR.…”

“…But they are not effective in multi-dimension featured domains, which consist of various industries or subjects. For knowledge extraction from multi-domain texts, Huang (2017) proposes a multi-dimensional semantic knowledge fusion framework for government website information analysis. It focuses on the domain ontology construction in multi-dimension featured data set.…”
