Journal ArticleDOI
Collective topical PageRank: a model to evaluate the topic-dependent academic impact of scientific papers
TL;DR: A pipeline model, named collective topical PageRank, is proposed, which incorporates the venue, the correlations of the scientific topics, and the publication year of each paper into a random walk to evaluate the topic-dependent impact of scientific papers.
Journal ArticleDOI
LF-LDA: A Supervised Topic Model for Multi-Label Documents Classification
TL;DR: There is a huge room for a multi-label classification of text-based documents, according to KeyWoRDS Function Terms.
Book ChapterDOI
LF-LDA: A Topic Model for Multi-label Classification
TL;DR: The experimental result on RCV1-v2 textual dataset shows that LF-LDA can outperform the other two state-of-art multi-label classifiers: Tuned SVM and L-L DA on both Macro-F1 and Micro-F 1 metrics, and the low variance also indicates LF- LDA is a robust classifier.
Journal ArticleDOI
Semi supervised classification of scientific and technical literature based on semi supervised hierarchical description of improved latent dirichlet allocation (LDA)
TL;DR: Proposed Chinese text classification method has higher classification accuracy and reflects effectiveness of design, and shows that proposed algorithm can generate DOG of knowledge conceptualization automatically.
Book ChapterDOI
Extraction and Tracking of Scientific Topics by LDA
TL;DR: An automatic LDA-based method to extract scientific topics and track their evolutions and a directed graph is constructed in terms of KL distances to tract the evolutions of topics and their relations.
