Abstract
The transformation of web of documents into web of data has brought an opportunity to integrate open government data of nations of the world. Linked data- the web of data, is now a hot topic in large number of organizations and countries and they seized this opportunity and are exploiting its functionalities and features. Developing countries like Ethiopia showed some interest in this area but has not yet developed adequate dataset due to capacity limitation in gathering and publishing data. This thesis designs an automatic linker that enables gathering of source data starting from the lower to the higher administrative division of a government and process the data to be ready for Open Data Cloud.
This work enables the upload of different types of data as input and performs removing duplications and domain mapping to ease the task of converting data to Turtle serializations where data is represented in URI format and stores it as RDF dump file. Then the RDF analyzer performs fixing the data from misplacement/duplication and link the RDF data to corresponding data on the LODC by the method of content negotiation. And finally publishing the data.
The implementation of this work has verified the fact that all functional processes in this work are realistic. Evaluation is done for the work and a measured based on performance and it has proven that the larger the data, the more time it will take to process. Data results can be obtained by encoding search key or SPARQL query statement in OG Linked Data Search Interface.
