“…Said Fathalla 11 described how investigations in the research field are represented semantically, thus forming a knowledge graph that describes various research questions, methods, and evaluations in a structured and comparable way. Some companies have used knowledge graphs to improve existing products and have developed prominent examples of large-scale knowledge graphs, including DBpedia 12 , Google knowledge graph 13 , Microsoft’s Satori 14 , Freebase, YAGO, and Wikidata 15 .

In the process design and reuse of marine component products, there are a lot of heterogeneous models, causing the problem that the process knowledge and process design experience contained in them are difficult to express and reuse. Therefore, a process knowledge representation model for ship heterogeneous model is proposed in this paper. Firstly, the multi-element process knowledge graph is constructed, and the heterogeneous ship model is described in a unified way. Then, the multi-strategy ontology mapping method is applied, and the semantic expression between the process knowledge graph and the entity model is realized. Finally, by obtaining implicit semantics based on case-based reasoning and checking the similarity of the matching results, the case knowledge reuse is achieved, to achieve rapid design of the process. This method provides reliable technical support for the design of ship component assembly and welding process, greatly shortens the design cycle, and improves the working efficiency. In addition, taking the double-deck bottom segment of a ship as an example, the process knowledge map of the heterogeneous model is constructed to realize the rapid design of ship process, which shows that the method can effectively acquire the process knowledge in the design case and improve the efficiency and intelligence of knowledge reuse in the process design of the heterogeneous model of a ship.

“…By using the generated knowledge graph to answer questions about the different contributions covered by the survey, and to evaluate how the query answers meet the reader's information needs compared with letting readers extract the same information from reading survey papers, to demonstrate the utility of the knowledge graph.

This method provides reliable technical support for the design of ship component assembly and welding process, greatly shortens the design cycle, and improves the working efficiency. In addition, a case study of the test model is carried out to verify the feasibility and efficiency of the proposed method.

“…Wikidata és una base de dades de coneixement estructurat que es manté de forma col•laborativa i que va ser creada l'any 2012 per la Fundació Wikimedia, amb l'objectiu d'esdevenir en una font de dades comuna per la seva reutilització tant a projectes de Wikimedia com per part d'altres institucions gràcies a la seva llicència d'ús de domini públic (Saorín i Pastor, 2018). Per una altra banda es proposen distints escenaris de treball dins l'àrea de Geografia i Història que es poden desenvolupar tant de manera transversal - Per concloure, afegir que l'anàlisi i la representació de les dades obertes suposa cada vegada més una competència substancial per delimitar la qualitat de la informació que arriba pels canals digitals, i que posar a l'abast de l'alumnat eines que els ajudin a processar-la serà cabdal per a la formació dels ciutadans del segle XXI.…”
