Cross-Media Scientific Research Achievements Retrieval Based on Deep Language Model

no code implementations29 Mar 2022 Benzhi Wang, Meiyu Liang, Feifei Kou, Mingying Xu

Science and technology big data contain a lot of cross-media information. There are images and texts in the scientific paper. The s ingle modal search method cannot well meet the needs of scientific researchers. This paper proposes a cross-media scientific research achievements retrieval method based on deep language model (CARDL). It achieves a unified cross-media semantic representation by learning the semantic association between different modal data, and is applied to the generation of text semantic vector of scientific research achievements, and then cross-media retrieval is realized through semantic similarity matching between different modal data. Experimental results show that the proposed CARDL method achieves better cross-modal retrieval performance than existing methods.
