| Abstract(in English) | A non-linear text is a directed graph where each vertex is labeled with a string. In this paper, we define Longest common substring/subsequence problems on Non-linear texts and solve them, to measure degree of similarity between two non-linear texts. We propose O(|E_1||E_2|)-time algorithms on acyclic non-linear texts, where |E_1|, |E_2| are the numbers of edges in the non-linear texts G_1, G_2. In addition we propose an O(|E_1|+|E_2|+|E'_1||E'_2|+|V'_1||V'_2|log|Σ|+|Σ|log|Σ|)-time algorithm to solve a longest common subsequence problem on cyclic non-linear texts, where |E'_1|, |E'_2|, (|V'_1|, |V'_2| are the numbers of edges and vertexes in the non-linear texts which are transformed from G_1, G_2. |
