Metaknowledge Extraction Based on Multi-Modal Documents
This work aims to improve the structural organization and hierarchical representation of knowledge for knowledge engineering researchers by introducing metaknowledge.
This paper introduces the concept of metaknowledge to address the lack of structural logic and hierarchical issues in triple-based knowledge bases. It presents a Metaknowledge Extraction Framework and Document Structure Tree model to extract and organize metaknowledge elements from multi-modal documents, demonstrating its effectiveness.
The triple-based knowledge in large-scale knowledge bases is most likely lacking in structural logic and problematic of conducting knowledge hierarchy. In this paper, we introduce the concept of metaknowledge to knowledge engineering research for the purpose of structural knowledge construction. Therefore, the Metaknowledge Extraction Framework and Document Structure Tree model are presented to extract and organize metaknowledge elements (titles, authors, abstracts, sections, paragraphs, etc.), so that it is feasible to extract the structural knowledge from multi-modal documents. Experiment results have proved the effectiveness of metaknowledge elements extraction by our framework. Meanwhile, detailed examples are given to demonstrate what exactly metaknowledge is and how to generate it. At the end of this paper, we propose and analyze the task flow of metaknowledge applications and the associations between knowledge and metaknowledge.
