A method of selecting a public data source by dynamically ranking publicly available data sources with respect to a search term, comprising a plurality of ranking processes carried out on the dataset for each data source and including: using metadata for each dataset to rank the datasets by comparing the search term against a dataset information for each source; creating a temporary ranking list of the data sources based on the metadata ranking; measuring availability for each of the data sources and updating the temporary ranking list based on availability; carrying out instance-based ranking based on fitness of the dataset in each data source against the search term to finalise the ranking list and using the finalised ranking list to select one or more data sources. |
