Pattern discovery using semantic network analysis
2012 3rd International Workshop on Cognitive Information Processing (CIP), 2012Cognitive information processing at higher conceptual levels requires a computational approach to knowledge representation and analysis. Semantic network analysis bridges the gap between probabilistic pattern recognition techniques and symbolic representations by replacing cumbersome and computationally complex forms of logic-based semantic inference ...

Neural networks for latent semantic analysis
2000 26th Annual Conference of the IEEE Industrial Electronics Society. IECON 2000. 2000 IEEE International Conference on Industrial Electronics, Control and Instrumentation. 21st Century Technologies and Industrial Opportunities (Cat. No.00CH37141), 2002Textual data can usually be represented by a large-dimensional matrix. For tasks such as information retrieval or information filtering, it is therefore necessary to reduce the dimensionality. A statistical method called latent semantic analysis (LSA) can be used not only for dimensional reduction but also for transformation of the original space into ...

Coloured semantic networks for content analysis
Quality & Quantity, 1994This paper adapts a widespread formalism of Knowledge Representation known in the AI literature as J. Sowa'sConceptual Graphs to the purposes of Content Analysis. It is proposed that instead of nested contexts, negation and modalities could be represented by colouring the links and the nodes of the graphs.

Towards Semantic-Based Social Network Analysis
2018 14th International Conference on Signal-Image Technology & Internet-Based Systems (SITIS), 2018We propose a semantic-based methodology for Social Network Analysis (SNA). This methodology addresses computations needed for SNA in a declarative way -in contrast to traditional SNA where computations are procedural. Our ingredients are semantic technologies: We define an ontology to represent graphs, their components (nodes, edges or paths), and the ...

Semantic Network Analysis on TCM Language System
IEEE International Workshop on Semantic Computing and Systems, 2008TCMLS is the largest traditional Chinese medicine ontology all over the world. This paper surveys the topology of TCMLS sub-ontologies in complex networks way. The result indicates that the network, composed of concepts and instances, displays both patterns of small-world and scale-free. Moreover, three centrality indices of nodes tend to covary in the

Keyphrase Extraction Using Semantic Networks Structure Analysis
Sixth International Conference on Data Mining (ICDM'06), 2006Keyphrases play a key role in text indexing, summarization and categorization. However, most of the existing keyphrase extraction approaches require human-labeled training sets. In this paper, we propose an automatic keyphrase extraction algorithm, which can be used in both supervised and unsupervised tasks.

Identifying Policy Frames Using Semantic Network Analysis
2019The case study demonstrates the identification and changes of policy frames in major countries as the policy context changes. This research has important implications for extracting policy frames from texts through semantic networks. Specifically, we want to share the researchers’ concerns about how to code texts, how to identify subgroups, and how to ...

A Semantic Network Analysis of The Network Neutrality Debate
SSRN Electronic Journal, 2015With nearly 4 million remarks, the 2014 proceeding that produced the recently released Open Internet Order stands as the most commented Federal Communications Commission (FCC) docket to date. According to FCC Chair Tom Wheeler, the volume and substance of this public input was crucial in shifting the agency’s final rules away from legal justifications ...

Semantic Social Network Analysis for Trend Identification
2012 IEEE Sixth International Conference on Semantic Computing, 2012This paper considers the extraction and analysis of Social Networks for the identification of trends. Our methodology focuses on the utilization of semantics for determination of relevant networks within unstructured data. The Social Networks are examined from the perspective of structure and considered as a time series.
