Plot　planning　is　a　very　important　part　in　the　mobile　phone　3D　animation　generation　system,　according　to　the　abstract　information,　which　is　extracted　from　a　Chinese　text,　it　plans　the　plot　of　a　specific　action　or　animated　scene.　In　this　paper　we　present　a　practice　of　applying　the　Semantic　Web　technologies　in　the　domain　of　Chinese　text,　build　an　ontology　and　a　rule　base　to　support　the　plot　planning　of　the　mobile　phone　3D　animation　generation　system,　which　enable　the　computer　to　understand　the　meaning　of　the　semantic　knowledge.
