As we accumulate more and more information online, we’re inclined to add more and more metadata—so we can order it, manage it, and re-find it. This growing belt of metadata is referred to as the “navigation layer.“ It‘s the series of filters, categories, tags, and other devices that let us to interact with information so we can sift out the noise.
What’s more, the navigation layer isn’t just about finding information—it can also help us make sense of the stuff we find. Sentiment analysis and entity extraction, for example, provide new insights into the information we come across. Ultimately, the navigation layer can point to high-order patterns that increase understanding.

  • Another type of metadata that has potential in the future is technically generated metadata. Text mining and algorithms can do a lot of the work. For instance, entity extraction can pick out proper names and key topics in news articles. Here is an example of top themes for a day from Google news. An algorithm picked this list and displayed them as “hot items” for the day. If you click one you then get all the news stories with mentions of those entities. This kind of metadata scales up quickly and once the algorithm is in place can be inexpensive to run. But isn’t easy to do and it might be inaccurate .As you can see from the results here, this is a mixed bag of things. Now that becomes another piece of metadata that we can use to search and sort on.

      • Berrypicking and information foraging are primitive metaphors. We need to be talking about metadata harvesting and sense making .

      • 1. Representation
      • How information is presented affects sense making
      • BUT representation is difficult in complex situations
        • Text-based Lists, trees, tables, clouds
        • Spatial Webs, diagrams
        • Graph-based Charts, graphs

      • The ability to manipulate information is critical
      • BUT there are effort-benefit tradeoffs
