For years, sentiment has been a widely used measure of how customers view a company’s products and services. But sentiment analysis has inherent flaws. First is what it cannot tell you because it only considers a small amount of the available data. Only about 25 percent of posts actually contain sentiment, either positive or negative, which means three out of four posts are neutral, revealing no sentiment, and are effectively being ignored by the analysis. Thus, decisions are being based on what only a quarter of the posts are saying.
Another problem with sentiment is statistical confidence in the data. Simply stated, all methods of sentiment analysis rely on example data that, whittled down, reveals a low level of confidence about the sentiment being identified, either positive or negative. Data with such low confidence is a poor foundation for sentiment analysis.
Bottom line — sentiment analysis is not inherently bad. In fact, for particular types of questions, it may be the right approach. But if you use it, you need to be sure that it’s the right tool for the job, that valuable data is not being ignored, and that the method of sentiment analysis is built on sound data.
A much more statistically reliable approach is semantic analysis — a way to distill and create structure around mountains of unstructured data, such as blog posts, social network chatter, tweets and more, without preconceived ideas of whether or how they are related.
Semantic analysis allows you to cluster different data elements based on similarity, rather than preset classifications such as positive, negative and neutral. This helps you uncover important information like what exactly people are saying about your product or service; where and how they use it; and enhancements or new offerings they’re interested in. This type of valuable information can drive product development, new revenue streams and strategies for marketing, advertising and media planning.
Social media information is expanding at such an amazing pace, organizations need new and innovative ways to capture “nuggets” of intelligence it can reveal. Semantic analysis can help harness and make sense of all that information — in exponentially more powerful ways than sentiment analysis. In fact, a valuable type of semantic analysis is topic discovery: the summarization of large amounts of text by automatically discovering the topics and themes within. Networked Insights’ new Topic Discovery Engine (TDE) is a semantic analysis system finely tuned to discover topics in social media posts.
Most exciting, with semantic analysis you have tremendous latitude about how you approach the analysis. You don’t have to be certain about what you’re looking for. How many times in your life can you say that lack of certainty gives you a leg up? With semantic analysis, you can let the social media speak for itself, revealing to you amazingly accurate and important information that can inform critical decisions.
