Improving Semantic Analysis in Visualization with Meta Network Representation and Parsing Algorithm

Abstract

This article aims to advance semantic analysis models, particularly in visualization, by proposing a novel semantic representation method utilizing the semantic Meta Network (MNet). MNet is a complex framework comprising semantic elements, internal and external relationships, and feature attributes, defined hierarchically through recursive processes, aiming to depict the comprehensive semantic space from phrase-level components to complete texts. The methodology involves the development of a general construction algorithm for MNet, encompassing meta relationships, tree structures, and network structures, and a Parsing method for specific semantic analysis problems, including a bottom-up specification-based MNet semantic dependency tree construction algorithm and a network construction algorithm tailored for natural language interface parsing. Empirical experiments confirm the effectiveness of these algorithms, particularly in parsing natural language control interface instructions in Supervisory Control and Data Acquisition (SCADA) systems, bridging specific semantic analysis problems with the general construction and parsing processes of MNet, accounting for internal semantics concerning language unit structures and foreign language meanings in the linguistic context, thereby contributing significantly to the field of natural language semantic analysis.
