clique definition
clique here means a maximum complete sub- graph where every two distinct vertices in the clique are adjacent. Extracting cliques from a given graph is a nontrivial problem and is shown to be NP-complete (Karp, 1972). In this paper, we adopt Bron-Kerbosch (BK) algorithm (Akkoyunlu, 1973) with pivoting (Johnston, 1976) to extract the cliques from a given graph. Having extracted the word cliques of two languages, we calculate clique embeddings by averaging the embedding vectors of all words in each clique. We choose the word whose embedding is closest to its clique embed- ding as the central word of each clique. After that, we follow Artetxe et al. (2018b) to map the cliques of two languages in a fully unsupervised way, i.e. to learn cross-lingual clique embeddings.
clique means that the three nodes are connected to each other
