Sentiment Analysis – Complex Definition
Sentiment analysis or opinion mining refers to a broad (definitionally challenged) area of natural language processing, computational linguistics and text mining. General speaking, it aims to determine the attitude of the speaker or writer with some respect to some topic. The attitude maybe their judgment or evaluation, their affective state – that is to say, the emotional state of the author when writing – or the intended emotional communication – that is to say, the emotional affect the author wants to have on the reader

Sentiment Analysis – Simple Definition
The simplest algorithms work by scanning keywords to categorize a statement as positive or negative, based on a simple binary analysis:
-“love” is good,
-“hate” is bad,
-“I don’t know,” which means there probably will not be a second date

Why Brands and Agencies Like Sentiment Analysis

Sentiment Analysis for Behavioral Research
21
Listening Platforms
• Buzz Metrics
• Radian6
• ScoutLabs
• Sysomos
• Techrigy’s
22
Text Mining Systems
• SAS
• Endeca
• Autonomy
• Lexalytics
• OpenAmplify
• You can get direct feeds to many social systems and mine text directly using solutions that are more powerful and tunable than those contained in most listening tools.
23
The Right Tool Depends on the Data
• If your analyzing tweets, you need a tool that understands acronyms and emoticons.
• Sentence analysis is different that article analysis. Twitter is more like sentence analysis.
• Topical classification, Objective v. Subjective, and Sentiment (polarity) are fundamentally different types of analysis.
24
An example of the Problem:
• Major software company looked at their major brand
• 80% of the comments were neutral
• 61% of the posts marked with a positive or negative sentiment came from microblogs.
• They were data oriented, general information
• But brands look at ‘Neutral’ and now what??
25
Issues
• Unreliable – not as good as pure human primary research
• Not sure what to do with Neutral
• No tool consistently identifies positive and neutral
• Inconsistency across tools
• Power of one or a small group of influencers
• Lack of Accuracy
26
Issues
• Inconsistent across social networks (Twitter is usually 60% neutral)
• Difficult to determine target
• Overlook actual verbatim
• No standards

Now What?So…Now What?

10 Steps to find the Diamond1 Decide on internal customer - which business unit, group will use data
2 Identify and use one tool (standardize on governance and set up)
3 Combine with other metrics/KPIs
4 Determine how broad you will go, but only look at one platform, community at a time
5 Identify emerging, trending topics
6 Take % of positive, neutral and negative
7 Take random sample of a 100 quotes from positive, neutral, negative, groups
8 Read verbatim
9 Categorize issues (For Intuit: Set up software vs. invoices vs. install vs. customer service)
10 Compare with other biggest competitors

Old School
• More skin in the game
• More engaged leads to greater satisfaction and places you closer to users/people
• More confidence in results
• Don’t drink and drive (I mean, don’t mix platforms)
