                •  Optimus  -  a  tool  to  turn  free  text  into  hierarchical  datasets  (3)  to
                   understand the movement of goods in the UK.

                These projects use a range of administrative data, geospatial data, data
            from  the  Internet  of  Things,  and  text,  and  tools  and  techniques  including
            machine learning, natural language processing and distributed computing to
            give fresh insights into the UK economy and the business behaviours which
            drive it. In Section 2, we briefly summarise our approach, and in Section 3,
            present an overview of the results. In Section 4, we discuss these results, and
            conclude with a summary of our findings.

            2.   Methodology
                2.1 Faster indicators of UK economic activity
                The faster indicator project set out to fast indicators of the UK economy
            using  novel  data  sources  based  on  administrative  data  and  data  from  the
            Internet of Things. It has three objectives:
                •  to identify close-to-real-time data which represent useful economic
                   concepts
                •  to  create  early  warning  indicators  of  potentially  large  economic
                   changes
                •  to provide new insights into economic activity, particularly around UK
                   ports
                It is important to note that we are not attempting to forecast or predict
            gross domestic product (GDP) or other headline economic statistics here, and
            the indicators should not be used in this way. Rather, by exploring big, closer-
            to-real-time datasets of activity likely to have an impact on the economy, we
            provide  an  early  picture  of  a  range  of  activities  that  supplement  official
            economic statistics and may aid economic and monetary policymakers and
            analysts in interpreting the economic situation in a timely way.
                From  UK  VAT  data,  we  have  created,  with  industry  breakdowns  where
            possible:
               •   several  monthly  and  quarterly  diffusion  indices  from  turnover  and
                   expenditure VAT returns
               •   novel  indicators  tracking  changes  in  VAT  reporting  (counts  of
                   repayments, re-inputs and replacements)
               •   a proxy for firm births, based on counts of new VAT reporters.
                We created shipping indicators from automatic identification system (AIS)
            data, which tracks ship location every few seconds whilst the ship is moving
            and  every  couple  of  minutes  whilst  it  is  in  port,  using  data  from  the  UK
            Maritime  and  Coastguard  Agency,  and,  via  the  UN  Global  Platform,  from
            ORBCOMM. We have used the data to construct monthly indicators of the
            time spent in port by ships, and the frequency of visits to ports, for the 10
