Metadata and data analytics

We’ve produced numerous data analytics explorations and products focused around the question of: ‘How can we better manage large and diverse collections of data’. Some examples are shown below.

Exploring metadata using Word2Vec

Through harvesting large metadata collections via Knowledge Network we have explored the relationship between metadata keywords using pre-trained machine learning through Word2Vec. Here we demonstrated the potential for better and new approaches to data discovery. The figure below demonstrates similarities between harvested metadata keywords.  See https://github.com/oznome/TagTagWord2Vec

Knowledge Network dataset themes visualisation

In this visualisation, we aggregated the keywords for each dataset record in the NSW OEH data catalogue and produced a visualisation to summarise the number of datasets with particular themes by size and colour. This provides users with the ability to understand the available data by themes and quantity at a glance.
