Data Partitioning for Semantic Web

Trupti Padiya, Mohit Ahir, Minal Bhise, Sanjay Chaudhary
2014 International journal of computer and communication technology  
Semantic web database is an RDF database. Tremendous increase can be seen in semantic web data, as real life applications of semantic web are using this data.  ...  Vertical partitioning, hybrid partitioning and property table was used to store the RDF data and query execution time is analyzed.  ...  LITERATURE REVIEW There are several data models available to store data. Here database model and semantic web model are of basic concern. These two data models are different from each other.  ...

Bridging the Technology Gap Between Industry and Semantic Web: Generating Databases and Server Code From RDF [article]

Markus Schröder, Michael Schulze, Christian Jilek, Andreas Dengel
2020 arXiv   pre-print
Potentials for improvements are identified, for example, the reduction of data redundancies in generated databases.  ...  In our evaluation, generated databases from different RDF datasets are examined and compared.  ...  Since data types of literals are not stored in our database, the currency of an offer's price can not be retrieved.  ...

Due to the proliferation of internet and the ease of creating and generating data on the fly -handling, storing and the subsequent semantic processing has proven to be a major bottleneck for the RDF data  ...  Indexing enormous databases such as RDF has been a focus of intense research. As is well understood, indexing plays a pivotal role in speeding up data retrieval operations and query performance.  ...  The experiments in these papers [8] and [9] reveals that the vertical partitioning approach also performs poorly for querying RDF data and slow insertion, because of the multi property tables.  ...
