abril 20th, 2011. Publicado por

Sentiment analysis continues to be one of the most debated areas in social media monitoring, so we thought we’d give a brief overview of the topic and how we approach it at Brandwatch. Here’s our resident expert, Dr Taras Zagibalov, who conducts all our language research and works alongside the tech team to continuously improve our automatic sentiment classification. Over to Taras:

There are two major techniques used in automatic sentiment analysis. The most frequently used one in commercial applications is based on linguistic resources, the other is based on machine learning.

Social Media Monitoring is bit like finding a needle in a haystack, or lots of needles but in a big haystack. For most brands there are dozens or hundreds of interesting mentions every day, but the problem is that they are hidden among thousands of less interesting or completely irrelevant mentions. Defining the query properly, with Boolean words like AND, NOT, OR etc., can reduce this problem so that it feels more like looking for needles in a mere handful of hay (apologies for stretching this metaphor uncomfortably far).

Brandwatch is a data company: our crawlers are dedicated to finding as many pages out there as they can. For our customers, higher volumes of data are generally better – they have more to work with, and can drill down using filters, keyword searches or browsing through topics.

The PURPOSE Of Social Search

julio 7th, 2008. Publicado por

Over the last 30 years, many tasks that humans once performed have been automated, encoded and passed over to computers. It’s the drive for efficiency that Bill Gates still talks about today. The internet however, never started off as a human-powered system so there was nothing to automate. But recently we have been witnessing the emergence of human-powered applications such as Social Search that are in some way competing with fully automated systems. »
