Understanding the data gaps in Wikidata concerning West Bengal

Background/Context[edit]

Wikidata is an online collaborative data repository built by volunteers from all around the world under public domain for everyone on the planet. It contains more than 67 million data items about different topics and its growing bigger every second. These items, stored in RDF format, are linked with each other, with other Wikimedia sister projects including Wikipedia and external websites and databases on different subjects. In spite of the diverse topics it has already covered, there are still huge data gaps, mostly in the Global South countries or regions.

We choose West Bengal from different Global South regions as volunteers here are being ingesting huge amounts of data concerning this area for the last few years into Wikidata. In this research, we are going to find out, if there are any major data gaps prevailing in Wikidata regarding the state of West Bengal and if there are data gaps, what are they and why they are there.

Research Problem/Objectives[edit]

The objectives of the research are to understand:

  • Problems caused by the existing data gaps in Wikidata concerning West Bengal ;
  • Strategies for filling up the data gaps

Proposed Methodology[edit]

Although Wikidata has more than 67 million items, it is not difficult to search anything from this huge database. Even finding answers to extremely specific questions are not much difficult as Wikidata is a structured database. This can be done by using SPARQL language, which are specifically designed to get answers from triplets, which is how Wikidata items are structured. Wikidata has a very powerful tool called Wikidata Query Service (WDQS) where users can write SPARQL queries for their questions and get answers from Wikidata in a structured way. WDQS can also be used for data visualizations in the form of maps, graphs, bubble charts, image grids, treemaps etc. In this research, we will find out data gaps prevailing in West Bengal using SPARQL based queries in WDQS. The queries will be on datasets on 5 topics; these will be selected based on criteria such as size and diversity of the dataset.
