How do we capture and model
the flow of information?
Given that social media generate a wealth of consumer data, how can brands turn raw
social media comment data from Twitter, Facebook, blogs, and forums into actionable
business insights? The answer lies in the application of text-mining and semantic
technology to these new sources of unstructured data.
How does it work?
• Text mining is similar to data mining in that it is aimed at identifying interesting patterns
• The first step in any text-mining effort is to identify the text-based sources to be
analysed and gather this material through information retrieval or selecting the corpus
that comprises the set of textual files and content of interest.
• Extensive NLP is deployed that invokes "part of speech tagging" and text sequencing to
parse for syntax (that is, tokenizing text) and applying Named Entity Recognition (that is,
identifying the mention of brands, people's names, places, common abbreviations, and
Text mining and semantic methods
Unique challenges exist when setting out to apply text mining to social media
data. The data that social networking sites, blogs, and forums generate falls in
the category of what is commonly referred to as big data. The data is
unstructured and semi-structured, petabytes are generated around larger
brands on a daily basis, and traditional relational databases cannot efficiently
scale to support real-time analytics based on the data. Big data and NoSQL
database solutions are therefore required.
Social media datamarts and big data
There are several commercial and open source options for text-mining software and
Of the open source text mining tools, RapidMiner and R appear to be two of the most
popular. R has a wider user base; a programming language in which source code is
required, it has a large selection of algorithms. However, scalability is an issue with R so it's
not ideal for large datasets without workarounds. RapidMiner has a smaller user base, but
it doesn't require source code and has a powerful user interface (UI).

Sentiment analysis depends on an appropriate subjectivity lexicon that understands the
relative positive, neutral or negative context of a word or expression. It is both language
and context specific.
A good example can be seen below:
I find PRODUCTX to be very good and useful, but it is a bit too expensive.
The expression (and therefore the PRODUCTX) is rated as positive, since there are two
positive words “good” and “useful” – and one negative word “expensive”. In addition, one
of the positive words is enhanced with the word “very” while the negative word is put
into perspective by the qualifier “a bit”. The more advanced the lexica, the more detailed
the analysis and the findings can be.
Sentiment analysis is a well-established, stand-alone predictive analytic technique.

These tools are generally cloud-based applications that pull many different social media
data sources (datasets) together including communities and blogs. They are able to do
this because they generally incorporate a massive back end infrastructure that constantly
crawls and captures new data as it occurs from the API’s.
They all provide an interface to filter the data and enter selection criteria to look across a
broad range of channel choices. The results usually take some form of a visual scorecard
that combines different graphical and tabular techniques for displaying the summarized
information. Many allow an interactive “drill down” to see further details, most of them
allowing you to drill right through to the original source of the data.
