Step 3: Create a Sentiment Analysis Dictionary
A sentiment analysis dictionary is a set of words that are categorized as positive, negative, or neutral. Here's how to create one:
- Open a new Excel sheet.
- Create three columns:
Word
,Sentiment
, andScore
. - Populate the dictionary with relevant words. For example:
<table> <tr> <th>Word</th> <th>Sentiment</th> <th>Score</th> </tr> <tr> <td>Amazing</td> <td>Positive</td> <td>1</td> </tr> <tr> <td>Bad</td> <td>Negative</td> <td>-1</td> </tr> </table>
Important Note: "Your dictionary can be expanded based on the domain you are working in."
Step 4: Calculate Sentiment Scores
To analyze sentiment, you'll need to score each review based on the words it contains. Follow these steps:
- Use the
SEARCH
function to identify sentiment words in the review text. - Create a formula to calculate the total sentiment score for each review.
Example Formula
Assuming your sentiment dictionary is in Sheet2 and your review text is in Sheet1:
=SUM(IFERROR(VLOOKUP(SEARCH(Sheet2!$A$2:$A$10, A2), Sheet2!$A$2:$C$10, 3, FALSE), 0))
This formula will scan the text in cell A2 for sentiment words listed in your dictionary and return the total sentiment score.
Step 5: Visualize Your Results
