摘要:
Since Budapest open access initiative was launched, a large number of full-text articles in the format of XML are available, which further promotes the technology management on the basis of citation context analysis, such as emerging technology forecasting, technology opportunity detection and innovation measurement. Inspired by the success of kernel functions utilized to promote the performance of SVM (Support Vector Machine) model, we explore the potential of combining generative and discriminative models for the task of citation function and importance classification. In more details, generative features are generated from a topic model, Citation Influence Model (CIM), and then fed to two state-of-the-art discriminative models, SVM and RF (Random Forest), with other 13 features derived from citation contexts directly to identify important citations from a brand new perspective. Extensive experimental results on a dataset from the Association for Computational Linguistics anthology indicate that our approach outperforms the counterparts. © 2020 ACM.
