Description
The Experts' Opinion (also refered to as the expert sentiment) chart tracks expert opinions, producing a score ranging from -1 sentiment (very negative) to +1 sentiment (very positive). Use this chart to make more informed decisions by tracking how experts feel about topics. Hover over each data point to see that day or hour's sentiment score, confidence interval, and top related story. If available, click the data point to open the story.

How & When to Use
Use this chart when attempting to determine if a topic is being discussed positively or negatively by experts.

This chart can be useful in some of the following situations:

• Identifying if a company is liked by experts in the field (typically translates to financial success)

• Tracking changes in the opinion around arbitrary topics, such as religion, food, etc.

Below is an example an Experts' Opinion chart, with various markers which are explained in more detail below.

1. The vertical axis ranges from -1 to +1
   • -1 represents the most negitive possible expert opinion
   • +1 represents the most possitive possible expert opinion


2. The Experts' Opinion trend line represents the aggregate sentiment (opinion) doman experts have about the topic
3. The score depicted is the probable score predicted based on the number of experts discussing at the time
4. The area / range comes from the possible range of the score, because not all experts discuss at any given time


5. The title of the chart provides the level of granulairty (in this case "daily"), as well as the date range
   • The granularity can be: daily, hourly, or minutely (yes, it's a word)
   • The date range can be anywhere from 2008 to today

Description
Net Promoter Scores are the typical, way companies measure the willingness of customers to recommend a company's products or services to others. The standard representation of this score, is an index ranging from -100 to 100. Usually, a company obtains this score by asking "would you recommend?" questions during an exit survey.

Our Promotional Score is similar, but noticiably improved.

We calculate our promotional score is calculated by counting the people actively promoting a topic, and subtracting by the number of people we see actively detracting. We then normalize it between -100 and 100, the same as standard representations.

Our approach creates much better results, as we can actually track people who are promoting a product, as opposed to say they will promote a product.

Description
The trend chart represents how active discussions are around this topic, regardless of postive or negative sentiment. A value of 0 represents no discussion, while a value of 1 represents a highly active discussion. This chart often correlates with sentiment changes, but is a seperate metric.

The greater the trend line, the greater the confidence we have for guaging experts' opinions and promotional scores.

We should note, this is similar to Google Trends, and is not explicitly based on expert sentiment(s).
