Bristol Social Media analytics company track Scottish Independence


As we know, social media monitoring or buzz monitoring is used in many sectors such as marketing, after-sales services or opinion polls. In 2010, Tweetminster has realized an analysis on buzz generated on Twitter about the British national elections. With a margin of error of 1.75%, the tool has shown a more accurate results than wellknown companies like YouGov145. This event had launched a debate on the reliability of measured data through social medias and on the possible correlation between the buzz generated and people's opinions.
Today, Bristol Social Media analytics company track Scottish Independence. What are people saying about Scottish Independence on social media? This has been an issue since the Act of Union was signed in 1707 – or even before that, going back to the Declaration of Arbroath in 1320 or the Battle of Bannockburn in 1314. Now the Scottish National Party Government in Edinburgh is planning to hold a referendum on Independence in 2014.
But is this relevant to people in Bristol? Churnbar, a Bristol-based social media monitoring and text analytics company, have produced a report on seven weeks of conversation in social media and online news, which shows that the issues raised by Scottish Independence could affect people south of the border.

Challenges of sentiment analysis tools in Buzz monitoring sector


(...) If topics can be automatically classified in a relatively simple way, sentiment analysis (positive, negative or neutral) gets harder as it requires a global analysis of the monitored text. This may be particularly difficult in cases of coordination between different parts of a sentence, of an anaphora or of a coreference (the recovery of an argument later in this document). 

Another difficulty of natural language for automatic analysis of sentiments are intentional contexts, for which the expression of opinion is not a true feeling. Thus, the phrase" I thought the trams were more modern" may be identified as positive when the intention is, however, negative. If the analysis of conversations are established by "word packets", the sentences "I like this model not only because of ..." and "I did not like this model only because of ... "a real problem. They are composed of the same packet of words but represent an opposite feeling. Lucas Dini et al. "Showed the relationship between syntactic and semantic structures of a sentence and the expression of the opinion that vehicle". 

The algorithm must be able to differentiate a neutral comment (eg: this car announces a fuel consumption of 3.3 l/100km) from an opinion (eg: this car announces a fuel consumption of only 3.3 l/100km!). It should also detect spelling errors, simplified syntaxes, slang or smileys. Finally it may be that a comment has positive and negative elements. Are they equal in value or is it that the positives outweigh? The phrase "I think this car is the best in its segment ... but also the most expensive "is an example of such ambiguity. What did the author say ? It is normal that its price is more high because of its beauty or the contrary, the price is not worth the candle? Even a human would have difficulty assigning a tone here.
