In order to track and limit the spread of faked news, we study stance identification of comments posted on OSM, where the stance can denote the comment\u2019s semantics. In this article, we propose a framework for identification of rumour stances, combining network topology and OSM comments. We construct a vector matrix of comments and words via OTI (optimisation term frequency\u2013inverse document frequency). To better identify the stances, we introduce another vector matrix with novel or special attribute, that is, network topology among the users. Variant autoencoder (VAE) is then applied for dimensionality reduction and optimisation of these vector matrices which are then combined into an integrated matrix [Formula: see text], tempered by two parameters [Formula: see text] and [Formula: see text]. Finally, the matrix is fed into a neural network for final rumour stance identification. Experimental evaluations show that our proposed approach outperforms some state-of-the-art methods and achieves a high precision of 90.26% and F1-score of 88.58%.<\/jats:p>","DOI":"10.1177\/0165551520944352","type":"journal-article","created":{"date-parts":[[2020,7,30]],"date-time":"2020-07-30T01:34:48Z","timestamp":1596072888000},"page":"118-130","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Identification
