| Abstract(in English) | We have proposed a novel search system harmonizing web search engines and social networking services. The proposed system uses a new ranking method which is based on PageRank algorithm and it takes the visitors of web pages and their relationship into account. In order to shorten the calculation time of our ranking method, we investigated SLEPc, a parallel computing library based on Open MPI and PETSc. We evaluated three calculation methods, Lanzcos, Arnoldi and Krylov-Schur, implemented in SLEPC. As a results we confirmed that we can complete the eigenvalue and the eigenvector calculation of a markov model matrix with handreds of thousands rows and columns in dozens of seconds. |
