Proceedings ArticleDOI
Mathematical Formula Identification in PDF Documents
TL;DR: A novel method by combining rule-based and learning-based methods to detect both isolated and embedded mathematical expressions in PDF documents is proposed and successfully incorporated into a commercial software package for large-scale Chinese e-Book production.
Journal ArticleDOI
Spatial correlation network structure of China's building carbon emissions and its driving factors: A social network analysis method.
TL;DR: Wang et al. as discussed by the authors adopted the social network analysis method to investigate the network structure characteristics of carbon emissions in the building sector based on China's provincial-level evidence from 2000 to 2018.
Proceedings ArticleDOI
A mathematics retrieval system for formulae in layout presentations
TL;DR: Experiments show that the new system along with novel algorithms, comparing with two representative mathematics retrieval systems, provides more efficient mathematical formula index and retrieval, while simplifying user query input for PDF documents.
Proceedings ArticleDOI
WikiMirs: a mathematical information retrieval system for wikipedia
TL;DR: Experimental results show that WikiMirs can efficiently support sub-structure matching and similarity matching of mathematical formulae, and obtains both higher accuracy and better ranked results over Wikipedia in comparison to Wikipedia Search and Egomath.
Proceedings ArticleDOI
Identification of embedded mathematical formulas in PDF documents using SVM
TL;DR: The method first segments text lines into words, and then classifies each word into two classes, namely formula or ordinary text, to build a robust and adaptable SVM classifier.
