**Algorithm for Designing a System to Analyze Customer Sentiment** 1. **Input:** Raw customer feedback data 2. **Output:** Analyzed customer sentiment **Steps:** 1. Pre-process the raw customer feedback data by removing punctuation and converting to lowercase (if necessary). 2. Tokenize the customer feedback data into individual words. 3. Remove stop words (common words such as “a”, “the”, etc.) from the customer feedback data. 4. Create a dictionary of words for the customer feedback data. 5. Tag the words in the customer feedback data with sentiment labels (positive, negative, or neutral). 6. Calculate the sentiment scores for the customer feedback data by summing the sentiment values of all words in the customer feedback data. 7. Output the sentiment scores of the customer feedback data. **Sample Code:** ```python # Input: Raw customer feedback data raw_data = "I really loved the product. It was great!" # Pre-process the raw customer feedback data processed_data = raw_data.lower().replace('.', '').split() # Tokenize the customer feedback data into individual words tokens = processed_data.split() # Remove stop words (common words such as “a”, “the”, etc.) from the customer feedback data stop_words = set(stopwords.words('english')) filtered_data = [word for word in tokens if not word in stop_words] # Create a dictionary of words for the customer feedback data dict = {"love": 1, "great": 1, "poor": -1, "bad": -1, "neutral": 0} # Tag the words in the customer feedback data with sentiment labels (positive, negative, or neutral) sentiment_labels = [] for word in filtered_data: if word in dict.keys(): sentiment_labels.append(dict[word]) # Calculate the sentiment scores for the customer feedback data by summing the sentiment values of all words in the customer feedback data sentiment_score = 0 for label in sentiment_labels: sentiment_score += label # Output the sentiment scores of the customer feedback data print("Sentiment Score:", sentiment_score) ```
