3. What is data and text mining?
» Text mining, also referred to as text data mining, roughly equivalent to text analytics, refers to the process of
deriving high-quality information from text.
» High-quality information is typically derived through the devising of patterns and trends through means such as
statistical pattern learning.
» Text mining usually involves the process of structuring the input text … deriving patterns within the structured data,
and finally evaluation and interpretation of the output.
» High quality' in text mining usually refers to some combination of relevance, novelty, and interestingness.
» Data Mining – is an imprecise term but means anything from
› Large scale data analysis within science - outputs of Hubl telecscope, Cern Large Hadron Collider
› Analysing census data for socio-economic trends (medium scale –finite amount of data )
› The opportunities of mining connected small objects/collections of research data to find new insight. e.g.
bringing together various versions of the Mona Lisa and using Data Mining to analyse their underlying structure.

5. What is its value for research and education?
» 2012 – Jisc published a key report
“Value and benefits of text mining
» https://www.jisc.ac.uk/reports/value-
and-benefits-of-text-mining
» Took a case study approach and also
under took an economic analysis of
the benefits (…biomedicine)
» Wider at scale benefits were harder
to come by owing to legal and
technical limitations in inhibiting
systematic use
» Since then new benefits have
emerged

6. What types of benefits?
» Finding research insights that were not
possible through other techniques
» Bringing together texts/data across
different discipline and finding new
insights
» “Text mining offers a way of helping
researchers to make sense of and
leverage value from the vast sea of
electronic resources, which is continually
expanding.”
» .”.potential to increase the research base
available to business and society and to
enable business and others to use the
research base more effectively”

10. Mining Repositories : Core
» CORE is an aggregation of OpenAccess Repositories and offers itself as a
platform forTDM (£25 million articles)
› Can use an API (of interest if want to build value add services on top
› Or - download the whole aggregation as an open dataset here:
https://core.ac.uk/intro/data_dump
› Jisc and the Open University running CORE in partnership, with the back-end aggregation hosted
by the OU and the front-end services hosted by Jisc. (Further services by Jisc could be developed
on top of this. )

11. Universities and Industry
» NCUB (NationalCouncil for Universities and Business) is developing a tool called
an “Intelligent Broker”
› To assist with making better links between University and Industry
› Could potentially harvest and mine data from key sources like the Research
Council’s Gateway to Research, equipment.data (national equipment portal)
and other services potentially - like Core.
› This would give SME’s more intelligence about research intensive activity in
particular areas for example

12. Content Mine
Grew out of a Jisc project initially

13. And Finally…
» Open Citation Experiment (usingText mining techniques –see Digifest session
and demo on this!)
» Jisc are commissioning a study to examine theText Mining landscape and future
contributions to this space to review:
› The current landscape - primarily in UK HE but also looking internationally, and within other
relevant sectors to provide a broad view.
› The market – what are the value chains and where might Jisc contribute?
› The legal position and other inhibitors
› Researcher practice, the issues they encounter, their current and future needs, considering
subjects that use and those that don’t
› Existing platforms, services and tools, and potential for use by Jisc or its customers
› Recommendations on possible future areas of work or services for Jisc to explore
