Description

There are several classes of errors in DBpedia. Data may be incorrect or missing. Errors may be caused by different reasons, for instance 1) wrong information or wrong format in Wikipedia or other original source; 2) the DBpedia Extraction Framework (DEF) might be making errors during automatic extraction; 3) there might be errors in the mappings or in the ontology. In this task you will browse through DBpedia entities, read Wikipedia pages, (optionally) run some SPARQL queries via the Web UI and analyze the results that come back. Your objective is to judge whether information is correct and try to detect the possible sources of error. You will log your findings in a spreadsheet that will be reviewed with one of the core developers of DBpedia. They will review your analysis and help you determine the source of error.

Impact

Data quality is one of the most important challenges in open data sets like DBpedia. By finding and categorizing errors, you will learn more about how DBpedia works and help us draft a plan of action that will efficiently improve our data quality by tackling the largest sources of errors first.

I'm interested in issue #2 and would like to work on this. Should I wait for this to be assigned to me or start working on it at the earliest?

Hi @PseudoNerd and thanks for your interest. The issues described in this page are just supposed to be warm-up tasks, so none of them is not going to be selected as a potential GSoC project. You're free to start working on it, however I'd recommend to focus on a project proposal for project #2.

Thank you.

Also, where should I send the first draft of the project proposal to the mentors(the project label says mentor-needed) for evaluation so that I could pointers for writing the final one?

We are still deciding who will be mentoring project #2, so by the rules @beyzayaman and I are co-mentors ad interim until we have a name.
