Iran Journal Article 2024 12 31 ‎A signed graph is a graph with signed edges‎. ‎Recently‎, ‎a special graph consisting of signed and unsigned edges has been introduced and is called a partially signed graph‎. ‎Also‎, ‎some properties of particular types of these graphs have been discussed‎. ‎Now‎, ‎in this article‎, ‎we pursue some other features of other types of partially signed graphs‎, ‎such as unicyclic and bipartite partially signed graphs and investigate the reconstruction of the characteristic from their polynomial decks‎.
