This paper proposes a method to construct Bilingual Movie Knowledge Graph (BMKG). The authors first builds Bilingual Movie Ontology (BMO) through a semi-automatic way, and aligns each data source with it in order to ensure semantic consistency of heterogeneous data sources. For entity linking, the proposed method makes best use of the field characteristics and calculate entity similarity based on both Word2Vec and TFIDF models, which greatly improve entity linking. For entity matching, a similarity flooding based algorithm is proposed, which utilizes the intrinsic links between the movie data sources, addressing the problem of similarity computation between cross-lingual entities. The experiment results show that the entity matching precision is over 90% when the threshold is above 0.75. In addition, a movie knowledge graph sharing platform is also built to provide open data access and query interface.

The field emission properties of a graphite paste film were found to have been greatly improved by nitrogen ion bombardment. The bombardment transformed the graphite surface into an array of graphite cones with a ～108cm^-2 tip density. XPS measurement showed that plenty of nitrogen had been injected into the graphite film and there existed a large number of sp2 bonds. Field emission test demonstrated that the distribution of the emission sites in the post, bombardment film was much more dense and uniform than that of the original one. The maximum current density of 1.65mA/cm² was also achieved, which was much higher than that of the pre, treatment sample.
