HIN2Vec swMATH ID: 37750 Software Authors: Tao-yang Fu, Wang-Chien Lee, Zhen Lei Description: HIN2Vec: Explore Meta-paths in Heterogeneous Information Networks for Representation Learning. In this paper, we propose a novel representation learning framework, namely HIN2Vec, for heterogeneous information networks (HINs). The core of the proposed framework is a neural network model, also called HIN2Vec, designed to capture the rich semantics embedded in HINs by exploiting different types of relationships among nodes. Given a set of relationships specified in forms of meta-paths in an HIN, HIN2Vec carries out multiple prediction training tasks jointly based on a target set of relationships to learn latent vectors of nodes and meta-paths in the HIN. In addition to model design, several issues unique to HIN2Vec, including regularization of meta-path vectors, node type selection in negative sampling, and cycles in random walks, are examined. To validate our ideas, we learn latent vectors of nodes using four large-scale real HIN datasets, including Blogcatalog, Yelp, DBLP and U.S. Patents, and use them as features for multi-label node classification and link prediction applications on those networks. Empirical results show that HIN2Vec soundly outperforms the state-of-the-art representation learning models for network data, including DeepWalk, LINE, node2vec, PTE, HINE and ESim, by 6.6 Homepage: https://dl.acm.org/doi/abs/10.1145/3132847.3132953 Source Code: https://github.com/csiesheep/hin2vec Related Software: PTE; metapath2vec; node2vec; DGL; ArnetMiner; GraRep; PyTorch; DeepWalk; word2vec; Freebase; GraphSAINT; ProNE; RotatE; InfoGraph; DropEdge; NetSMF; GE-SpMM; BioGRID; Optuna; CogDL Cited in: 5 Publications all top 5 Cited by 25 Authors 2 Xia, Feng 2 Zhang, Da 1 Bedru, Hayat Dino 1 Fournier-S’niehotta, Raphaël 1 Guo, He 1 Han, Jiawei 1 Hou, Mingliang 1 Kong, Xiangjie 1 Kuželka, Ondřej 1 Lamarche-Perrin, Robin 1 Li, Haoran 1 Poulain, Rémy 1 Ramaciotti Morales, Pedro 1 Ren, Jing 1 Song, Yangqiu 1 Šourek, Gustav 1 Tabourier, Lionel 1 Tarissan, Fabien 1 Wan, Liangtian 1 Wang, Chenguang 1 Xiao, Xinru 1 Yu, Shuo 1 Železný, Filip 1 Zhang, Dongyu 1 Zhang, Ming Cited in 4 Serials 2 Computer Science Review 1 Theoretical Computer Science 1 Machine Learning 1 Data Mining and Knowledge Discovery Cited in 5 Fields 4 Computer science (68-XX) 3 Combinatorics (05-XX) 2 Game theory, economics, finance, and other social and behavioral sciences (91-XX) 1 Statistics (62-XX) 1 Operations research, mathematical programming (90-XX) Citations by Year
