THE WORD’S OUT<br />
Language, social media and thought<br />
Social media is all about language and the<br />
written word. People are writing more than<br />
ever before with status updates, tweets<br />
and blogs. There is now a constant stream of text<br />
about what we do and think. Of course this is a<br />
huge opportunity for market <strong>research</strong>.<br />
The question becomes how to process the<br />
never-ending streams of text available on social<br />
media. Computers are good at calculations, but<br />
text analysis has always been the problem child.<br />
Language has a complexity that simple numbers<br />
can’t capture.<br />
Two schools of thought seem to be crystallising<br />
as to how we analyse social media. The first<br />
emphasises what is generally called ‘natural<br />
language processing’. Using this approach comprehension<br />
comes via computerised parsing and<br />
analysis of the text based on our understanding<br />
of language. Grammar is the key. The second<br />
approach is statistical. It emphasises analytical<br />
techniques such as Latent Semantic Analysis<br />
(LSA), which uses the statistical properties of text<br />
to glean meaning from it.<br />
Text analytics is the new frontier that market<br />
<strong>research</strong> must conquer. The sheer volume of text<br />
can’t be ignored, but it can’t be coded and tabulated<br />
the same way open ends are today. There is simply<br />
too much. In some senses the contest of grammar<br />
versus statistics has already been decided. When<br />
you look at text from social media it isn’t grammatically<br />
correct, because we don’t speak and<br />
communicate in formal blocks of text using perfect<br />
grammar. Hence the grammar route is fundamentally<br />
at a disadvantage. The argot of web may well<br />
defy parsing. It’s significant that search engines<br />
such as Google and Yahoo use techniques very close<br />
to LSA to process documents and decide how they<br />
are related. The core metric of LSA is word counts<br />
and co-occurrence of words in documents. Given<br />
that search engines are the tools that have made the<br />
web usable it is worth paying attention to this.<br />
The problem is sentiment. One of the critical<br />
tasks for analysis of social media is deciding if a<br />
tweet or status update has a positive or negative<br />
tone. Is the buzz about a product good or bad If you<br />
can automatically tell the sentiment of comments<br />
relating to products or services you have a powerful<br />
<strong>research</strong> tool. Sentiment analysis is currently a hard<br />
thing to do accurately. Anything over 75 per cent accuracy<br />
in sentiment analysis is currently regarded<br />
as pretty good, but this still leaves a large margin<br />
for error. At the moment the only accurate way to<br />
assess sentiment is for a human to read the text,<br />
but there is simply too much text being produced by<br />
social media for this to be practical.<br />
Sentiment analysis of social media is rapidly<br />
becoming the ultimate goal for text analysis and<br />
market <strong>research</strong>. We need more sentiment to<br />
master social media.<br />
