Book recommendation using Neo4j graph database in BibTeX book metadata

In digital era, book has an important role in life. There are not only a lot of books for different purpose. But also, there are many book metadata which can use for another reason, such as book recommendation. By processing the book metadata, an information can be given to user that needs book recommendation. By combining BibTeX book metadata and Graph Database from Neo4j, data from metadata can be processed. Then, with cypher query by inputting author's parameter or book type's parameter, user can get book recommendation based on their input's criteria. The result is exactly the same with process the metadata manually in relational database. Neo4j, from this paper, takes 180 milliseconds to execute cypher query with author's criteria and takes 184 milliseconds to execute cypher query with book type's criteria.
