--- title: "Text Analysis on Scraped Comments: Extract Themes, Sentiment & Keywords" description: "Learn text analysis on scraped comments and reviews using keywords, sentiment, topic models, and named entities with Python, ChatGPT, or no-code tools." canonical: https://tryadlicio.com/blog/text-analysis-reviews --- # Text Analysis on Scraped Comments: Extract Themes, Sentiment & Keywords Published 2026-03-13. https://tryadlicio.com/blog/text-analysis-reviews **Quick Summary:** Text analysis on scraped reviews and comments turns raw user feedback into structured insights. This guide covers five core techniques -- keyword extraction, sentiment analysis, topic modeling, n-gram analysis, and named entity recognition -- using Python (NLTK, spaCy, VADER), AI tools like ChatGPT and Claude, and no-code platforms like MonkeyLearn. The first step is always data collection: [Comment Exporter](https://chromewebstore.google.com/detail/comment-exporter-reddit-y/ahjjidbbielmekkaklabocljkljbmnlm) lets you export comments from Reddit, YouTube, Amazon, and 6 other platforms to CSV in one click -- free for Reddit. ### Key Points: - **Five Core Techniques:** Keyword extraction, sentiment analysis, topic modeling, n-gram analysis, and named entity recognition each answer a different question about your review data. - **No Coding Required:** ChatGPT, Claude, [MonkeyLearn](https://monkeylearn.com/), and [Google Sheets](https://workspace.google.com/products/sheets/) formulas let you run text analysis without writing a single line of code. - **Python Power Users:** [NLTK](https://www.nltk.org/), [spaCy](https://spacy.io/), and VADER provide full control over text analysis pipelines for repeatable, large-scale analysis. - **Data Collection First:** Every text analysis workflow starts with clean, structured data -- [Comment Exporter](/scrapers/reddit-comment-scraper) handles this step across 11 platforms with one-click CSV export. - **Combine Techniques:** The most actionable insights come from layering multiple methods -- for example, running [sentiment analysis](/blog/reddit-sentiment-analysis) alongside keyword extraction to see not just what people discuss but how they feel about it. Comment Exporter is rated 5.0 on the [Chrome Web Store](https://chromewebstore.google.com/detail/reddit-comment-scraper/ahjjidbbielmekkaklabocljkljbmnlm) and used by 10,000+ researchers, analysts, and marketers every week. ## Why Text Analysis Matters for Scraped Reviews Scraping comments is the easy part. You install a browser extension, hit export, and within seconds you have a CSV file with hundreds or thousands of rows of raw user feedback. The hard part -- the part that actually produces business value -- is turning that wall of unstructured text into patterns, categories, and actionable insights. Text analysis bridges that gap. It is the umbrella term for a set of natural language processing (NLP) techniques that extract meaning from written text. When applied to scraped reviews and comments, these techniques answer questions that no amount of manual reading could answer at scale: What topics come up most frequently? Is sentiment trending positive or negative over time? Which product features generate the most complaints? What specific brands or competitors do customers mention? > "The value of scraped review data is not in the raw text -- it is in the patterns you extract from it. Text analysis transforms noise into signal, giving brands a structured view of what customers actually care about." > > \-- Shane Barker, Founder of [TraceFuse.ai](https://tracefuse.ai/) Consider the scale: a single Reddit thread can generate 500+ comments. An Amazon product listing might have 3,000 reviews. No human can read all of that and identify patterns reliably. Text analysis algorithms can process the entire dataset in seconds and surface the themes, sentiments, and entities that matter most. Whether you are running [market research on Reddit](/blog/reddit-market-research-guide), performing [competitive analysis through reviews](/blog/competitor-analysis-using-reviews), or conducting [academic research on online discourse](/blog/academic-research-scraping-guide), text analysis is the skill that turns data collection into data intelligence. ## Step 0: Collecting Your Data with Comment Exporter Every text analysis workflow starts with data. Before you can extract keywords, score sentiment, or build topic models, you need a clean, structured dataset of comments or reviews. This is where [Comment Exporter](/scrapers/reddit-comment-scraper) fits into the pipeline. Instead of writing Python scripts with [PRAW](/blog/reddit-api-pricing-alternative) or dealing with API rate limits, Comment Exporter lets you export comments directly from your browser: 1. Navigate to the Reddit thread, YouTube video, Amazon product page, or any of the 11 supported platforms. 2. Open the Comment Exporter extension and click "Scrape Comments." 3. Export the data as CSV or JSON -- ready for analysis. The exported CSV includes the comment text alongside metadata like timestamps, upvotes, author names, and reply counts. This metadata becomes valuable during analysis -- for example, weighting sentiment scores by upvote count or filtering by date range to track opinion shifts over time. **Start with clean data.** Comment Exporter handles platform-specific parsing, encoding, and formatting at export time -- so your text analysis begins with structured, clean CSV rather than raw HTML. Reddit export is completely free. [Add to Chrome — Free](https://chromewebstore.google.com/detail/comment-exporter-reddit-y/ahjjidbbielmekkaklabocljkljbmnlm) > "I used to spend an hour copying Reddit comments into spreadsheets. Now I export 400+ comments in seconds and go straight to analysis in Python. Comment Exporter is the first step in every research project." > > \-- Mitran Marian, Data Analyst ## Technique 1: Keyword Extraction Keyword extraction is the simplest and often the most immediately useful form of text analysis. It answers the question: what words and phrases appear most frequently in this dataset? By identifying the most common terms, you get a fast overview of what customers are talking about -- which features they mention, which problems they report, and which competitors they compare against. ### Keyword Extraction with Python (NLTK) The [Natural Language Toolkit (NLTK)](https://www.nltk.org/) is the standard library for text processing in [Python](https://www.python.org/). Here is a basic keyword extraction pipeline for scraped review data: ``` import pandas as pd import nltk from nltk.corpus import stopwords from nltk.tokenize import word_tokenize from collections import Counter nltk.download('punkt') nltk.download('stopwords') # Load your exported comments df = pd.read_csv("reddit_comments.csv") # Combine all comment text all_text = " ".join(df["body"].dropna().astype(str).tolist()) # Tokenize and clean tokens = word_tokenize(all_text.lower()) stop_words = set(stopwords.words("english")) keywords = [t for t in tokens if t.isalpha() and t not in stop_words and len(t) > 2] # Get top 30 keywords top_keywords = Counter(keywords).most_common(30) for word, count in top_keywords: print(f"{word}: {count}") ``` This script tokenizes every comment, removes common English stop words (the, is, and, etc.), filters out short tokens, and ranks the remaining words by frequency. The output immediately tells you which terms dominate the conversation. ### Keyword Extraction with ChatGPT or Claude If you prefer a no-code approach, export your comments to CSV with [Comment Exporter](/scrapers/reddit-comment-scraper), then upload the file to [ChatGPT](https://chatgpt.com/) or [Claude](/blog/analyze-reviews-with-claude) with a prompt like: ``` Analyze this CSV of scraped Reddit comments. Extract the top 20 keywords and phrases that appear most frequently. Group them by theme (product features, complaints, praise, competitors mentioned). For each keyword, include the approximate frequency count. ``` AI tools excel at contextual keyword extraction -- they understand that "battery life," "battery drain," and "dies fast" all refer to the same concept, something a simple word count would miss. For detailed prompting strategies, see our guide on [analyzing reviews with ChatGPT](/blog/analyze-reviews-with-chatgpt). ### Keyword Extraction in Google Sheets For small datasets (under 500 rows), [Google Sheets](https://workspace.google.com/products/sheets/) can handle basic keyword frequency analysis. Create a list of target keywords in column D, then count how often each appears across all comments: ``` =SUMPRODUCT(LEN(B$2:B$500)-LEN(SUBSTITUTE(LOWER(B$2:B$500),LOWER(D2),"")))/LEN(D2) ``` This formula counts every occurrence of a keyword across your entire comment column. It is not as sophisticated as NLP-based extraction, but it works when you already have a hypothesis about which terms matter. ## Technique 2: Sentiment Analysis Sentiment analysis scores each comment on an emotional scale -- typically positive, negative, or neutral. It is the most popular form of **text analysis reviews** because it directly answers the question: how do people feel about this topic? ### Sentiment Analysis with VADER VADER (Valence Aware Dictionary and sEntiment Reasoner) is specifically designed for social media text. It understands slang, capitalization, punctuation, and emoji -- all common in scraped comments. VADER is part of the [NLTK](https://www.nltk.org/) library: ``` import pandas as pd from nltk.sentiment.vader import SentimentIntensityAnalyzer # Load exported comments df = pd.read_csv("reddit_comments.csv") # Initialize VADER sid = SentimentIntensityAnalyzer() # Score each comment df["sentiment_scores"] = df["body"].apply( lambda x: sid.polarity_scores(str(x)) ) df["compound"] = df["sentiment_scores"].apply(lambda x: x["compound"]) # Classify sentiment df["sentiment"] = df["compound"].apply( lambda x: "positive" if x >= 0.05 else ("negative" if x <= -0.05 else "neutral") ) # Summary print(df["sentiment"].value_counts(normalize=True).round(3)) ``` VADER returns a compound score between -1 (most negative) and +1 (most positive). Comments with a compound score above 0.05 are classified as positive, below -0.05 as negative, and everything in between as neutral. For a deeper dive into this technique, see our [complete guide to Reddit sentiment analysis](/blog/reddit-sentiment-analysis). ### Sentiment Analysis with MonkeyLearn (No Code) [MonkeyLearn](https://monkeylearn.com/) offers a visual, no-code interface for sentiment analysis. Upload your CSV, map the text column, and MonkeyLearn scores every row as positive, negative, or neutral. It also provides confidence percentages for each classification. The free tier handles up to 300 queries per month -- enough for initial exploration before committing to a paid plan or switching to Python for larger datasets. ### Combining Sentiment with Metadata Raw sentiment scores become significantly more useful when you cross-reference them with the metadata from your export. Comment Exporter includes timestamps, upvote counts, and reply counts -- which enable analyses like: - **Sentiment over time:** Plot average compound score by week to track opinion shifts after product launches or PR events. - **Weighted sentiment:** Multiply each comment's sentiment by its upvote count to give more weight to comments the community agrees with. - **Sentiment by engagement:** Compare the sentiment of highly upvoted comments versus low-engagement ones to see if vocal minorities skew the overall tone. ## Technique 3: Topic Modeling While keyword extraction tells you which individual words appear most, topic modeling groups those words into coherent themes. It answers the question: what are the main subjects people are discussing? Topic modeling is unsupervised -- you do not need to define the topics in advance. The algorithm discovers them from the data. ### LDA Topic Modeling with Python Latent Dirichlet Allocation (LDA) is the most widely used topic modeling algorithm. It assigns each document (comment) to a mix of topics, and each topic is defined by a cluster of co-occurring words. Here is a pipeline using [scikit-learn](https://scikit-learn.org/): ``` import pandas as pd from sklearn.feature_extraction.text import CountVectorizer from sklearn.decomposition import LatentDirichletAllocation # Load comments df = pd.read_csv("reddit_comments.csv") texts = df["body"].dropna().astype(str).tolist() # Create document-term matrix vectorizer = CountVectorizer( max_df=0.95, min_df=2, stop_words="english", max_features=1000 ) dtm = vectorizer.fit_transform(texts) # Fit LDA model with 5 topics lda = LatentDirichletAllocation(n_components=5, random_state=42) lda.fit(dtm) # Display top words per topic feature_names = vectorizer.get_feature_names_out() for idx, topic in enumerate(lda.components_): top_words = [feature_names[i] for i in topic.argsort()[-10:]] print(f"Topic {idx + 1}: {', '.join(top_words)}") ``` The output might look like this for a dataset of scraped comments from a headphone subreddit: - **Topic 1:** sound, quality, bass, treble, clear, music, audio, balanced, flat, warm - **Topic 2:** price, expensive, worth, budget, cheap, value, deal, sale, cost, money - **Topic 3:** comfort, ear, pad, wear, hours, head, tight, pressure, light, fit - **Topic 4:** bluetooth, wireless, battery, charge, connection, latency, cable, dongle, usb, pairing - **Topic 5:** noise, cancelling, anc, isolation, ambient, mode, transparency, airplane, office, quiet Each topic represents a distinct theme in the conversation. This is far more informative than a flat keyword list because it shows you the structure of the discussion. ### Topic Modeling with ChatGPT For smaller datasets, AI tools handle topic modeling effectively. Upload your CSV to [ChatGPT](https://chatgpt.com/) and use this prompt: ``` I have a CSV of scraped comments from a Reddit thread about [topic]. Read all the comments and identify the 5-7 main themes people are discussing. For each theme, provide: 1. A descriptive label 2. The approximate percentage of comments that touch on this theme 3. The overall sentiment within this theme (positive/negative/mixed) 4. 2-3 representative quotes from the data ``` This approach is especially useful for [voice of customer analysis](/blog/voice-of-customer-tools) where you need human-readable theme labels rather than raw word clusters. ## Technique 4: N-Gram Analysis N-gram analysis extends keyword extraction from single words to multi-word phrases. A bigram is a two-word sequence ("battery life"), a trigram is three words ("noise cancelling headphones"), and so on. N-grams capture meaning that single keywords miss -- "not good" carries the opposite sentiment of "good," and n-gram analysis preserves that context. ### N-Gram Extraction with Python ``` import pandas as pd from sklearn.feature_extraction.text import CountVectorizer # Load exported comments df = pd.read_csv("reddit_comments.csv") texts = df["body"].dropna().astype(str).tolist() # Extract bigrams (2-word phrases) bigram_vectorizer = CountVectorizer( ngram_range=(2, 2), stop_words="english", max_features=50 ) bigram_matrix = bigram_vectorizer.fit_transform(texts) bigram_counts = bigram_matrix.sum(axis=0).A1 bigram_freq = sorted( zip(bigram_vectorizer.get_feature_names_out(), bigram_counts), key=lambda x: x[1], reverse=True ) print("Top 20 Bigrams:") for phrase, count in bigram_freq[:20]: print(f" {phrase}: {count}") # Extract trigrams (3-word phrases) trigram_vectorizer = CountVectorizer( ngram_range=(3, 3), stop_words="english", max_features=50 ) trigram_matrix = trigram_vectorizer.fit_transform(texts) trigram_counts = trigram_matrix.sum(axis=0).A1 trigram_freq = sorted( zip(trigram_vectorizer.get_feature_names_out(), trigram_counts), key=lambda x: x[1], reverse=True ) print("\nTop 20 Trigrams:") for phrase, count in trigram_freq[:20]: print(f" {phrase}: {count}") ``` N-gram analysis is particularly powerful for identifying specific complaints and feature requests. When single keyword analysis shows "battery" as a top term, n-gram analysis reveals whether people are saying "battery life amazing," "battery drains fast," or "battery replacement cost" -- three very different signals. ### N-Gram Analysis in Google Sheets For a manual approach in [Google Sheets](https://workspace.google.com/products/sheets/), you can count specific phrase occurrences using: ``` =SUMPRODUCT((LEN(B$2:B$500)-LEN(SUBSTITUTE(LOWER(B$2:B$500),"battery life","")))/LEN("battery life")) ``` This counts how many times "battery life" appears across all comments. Create a list of hypothesized bigrams and run this formula for each one. While less automated than Python, it works well when you already know which phrases to look for based on initial keyword analysis. ## Technique 5: Named Entity Recognition (NER) Named entity recognition identifies specific real-world entities mentioned in text -- brand names, product names, people, locations, organizations, and monetary values. NER answers questions like: which competitors do customers mention? Which specific product models are being compared? Which influencers or reviewers are referenced? ### NER with spaCy [spaCy](https://spacy.io/) is an industrial-strength NLP library that includes pre-trained NER models. It recognizes entities like organizations (ORG), products (PRODUCT), people (PERSON), monetary values (MONEY), and locations (GPE) out of the box: ``` import pandas as pd import spacy from collections import Counter # Load spaCy's English model nlp = spacy.load("en_core_web_sm") # Load exported comments df = pd.read_csv("reddit_comments.csv") texts = df["body"].dropna().astype(str).tolist() # Extract entities from all comments entities = [] for text in texts: doc = nlp(text) for ent in doc.ents: entities.append((ent.text, ent.label_)) # Count entity frequencies by type org_counts = Counter( [e[0] for e in entities if e[1] == "ORG"] ).most_common(15) product_counts = Counter( [e[0] for e in entities if e[1] == "PRODUCT"] ).most_common(15) person_counts = Counter( [e[0] for e in entities if e[1] == "PERSON"] ).most_common(10) print("Top Organizations Mentioned:") for name, count in org_counts: print(f" {name}: {count}") print("\nTop Products Mentioned:") for name, count in product_counts: print(f" {name}: {count}") ``` NER is especially valuable for [competitive analysis](/blog/competitor-analysis-using-reviews). When you scrape a discussion thread about your product, NER automatically identifies every competitor brand and product that customers mention in the same breath. This tells you exactly who your customers are comparing you against -- without manually reading thousands of comments. ### NER with ChatGPT or Claude AI tools handle named entity recognition intuitively. Upload your CSV and prompt: ``` Analyze these scraped comments and extract every brand name, product name, person name, and specific feature mentioned. Create a table with columns: Entity, Type (brand/product/person/feature), Mention Count, and Typical Context (positive/negative/neutral). ``` This approach is slower than spaCy for large datasets but produces more nuanced results because GPT-4 and Claude understand context better than rule-based NER models -- they know that "Apple" in a tech discussion refers to the company, not the fruit. ## Building a Complete Text Analysis Pipeline Individual techniques are useful, but the real power comes from combining them into a structured pipeline. Here is a practical workflow that takes you from raw scraped data to actionable insights: ### Phase 1: Collect and Clean 1. **Export comments** from your target platform using [Comment Exporter](/scrapers/reddit-comment-scraper). The extension handles encoding, deduplication, and formatting at export time. 2. **Clean the dataset** following the steps in our [guide to cleaning scraped review data](/blog/clean-scraped-review-data) -- remove deleted comments, handle missing fields, and standardize the text column. ### Phase 2: Explore 3. **Run keyword extraction** to identify the most frequent terms. This gives you an initial map of what the dataset contains. 4. **Run n-gram analysis** to surface multi-word phrases and catch contextual meaning that single keywords miss. ### Phase 3: Analyze 5. **Score sentiment** for every comment using VADER, TextBlob, or an AI tool. This quantifies the emotional tone across the entire dataset. 6. **Build topic models** to discover the 5-7 main themes in the conversation. Label each topic based on its top words. 7. **Run NER** to extract brands, products, and people mentioned. Cross-reference entity mentions with sentiment scores to see which brands are discussed positively versus negatively. ### Phase 4: Report 8. **Combine the outputs** into a summary: top keywords, sentiment distribution, main topics with sentiment breakdown, and key entities with their associated sentiment. > "I run this exact pipeline every month on scraped Reddit comments and Google Reviews for three competing products. The topic model shows me emerging complaints before they hit mainstream reviews, and the NER output tracks exactly which competitors are gaining mindshare." > > \-- Alfon Labadan, Product Researcher ## Key Metadata Fields for Text Analysis The quality of your text analysis depends not just on the comment text but on the metadata that accompanies it. Comment Exporter provides structured metadata fields that enable richer analysis. Here is how each field supports text analysis: | Field | Description | Text Analysis Use Case | Example | | --- | --- | --- | --- | | Comment Text | The full comment or review body | Primary input for all NLP techniques | "The battery life is incredible but the noise cancelling..." | | Timestamp | When the comment was posted | Sentiment trend analysis over time | 2026-03-10T14:22:00Z | | Upvotes/Score | Community agreement metric | Weight sentiment by community consensus | 147 | | Author | Username of the commenter | Identify power users and repeat commenters | u/audiophile\_mike | | Reply Count | Number of replies to a comment | Identify controversial or discussion-sparking topics | 23 | | Thread/Post Title | Title of the parent thread | Contextualize comments within discussion framing | "Sony WH-1000XM6 vs Bose QC Ultra Review" | | Platform | Source platform of the comment | Cross-platform sentiment comparison | Reddit / YouTube / Amazon | | Star Rating | Numeric rating (platform-dependent) | Validate sentiment scores against explicit ratings | 4 / 5 | ### Best Practices for Metadata-Enhanced Analysis - **Always filter before analyzing:** Remove deleted comments, bot replies, and auto-moderator messages before running any NLP pipeline. See our [data cleaning guide](/blog/clean-scraped-review-data) for the complete checklist. - **Use timestamps for trend analysis:** Group comments by week or month and plot sentiment scores over time. This reveals shifts in public opinion after product launches, updates, or controversies. - **Weight by engagement:** A comment with 200 upvotes represents community consensus more than a comment with 1 upvote. Multiply sentiment scores by normalized engagement scores for weighted averages. - **Cross-reference platforms:** Export the same topic from Reddit, YouTube, and Amazon using Comment Exporter, then compare keyword frequencies and sentiment distributions across platforms. Different audiences surface different concerns. - **Export both CSV and JSON:** CSV works best for spreadsheet-based analysis and AI uploads. JSON preserves threaded comment structures, which matters for conversation flow analysis. ## Tools Comparison: Python vs No-Code vs AI Choosing the right tool depends on your dataset size, technical comfort, and how often you plan to repeat the analysis. Here is a practical comparison: | Tool | Best For | Dataset Size | Learning Curve | Cost | | --- | --- | --- | --- | --- | | [Python](https://www.python.org/) (NLTK, spaCy) | Repeatable pipelines, large datasets, full control | Unlimited | Medium-High | Free | | VADER (Python) | Social media sentiment specifically | Unlimited | Low-Medium | Free | | [ChatGPT](https://chatgpt.com/) / Claude | Exploratory analysis, contextual understanding | Up to ~2,000 rows per session | Low | $20/mo (Pro) | | [MonkeyLearn](https://monkeylearn.com/) | Visual no-code sentiment and keyword extraction | Up to 10,000 rows | Low | Free tier / Paid plans | | [Google Sheets](https://workspace.google.com/products/sheets/) | Quick keyword counting, small datasets | Under 500 rows | Low | Free | | [Excel](https://www.microsoft.com/en-us/microsoft-365/excel) | Sorting, filtering, basic frequency analysis | Under 10,000 rows | Low | Paid (Microsoft 365) | For most analysts working with scraped review data, the practical path is: start with ChatGPT or Claude for exploration, then move to Python for repeatable analysis once you know what questions to ask. Use [AI review analysis tools](/blog/best-ai-review-analysis-tools) for the thinking, and Python for the automation. ## Real-World Use Cases ### Product Feature Prioritization A product manager scrapes 2,000 Reddit comments about their SaaS tool using Comment Exporter. Keyword extraction reveals "integrations" as the #1 term. N-gram analysis narrows it down: "Slack integration," "API access," and "Zapier support" are the top three bigrams. Topic modeling shows that integration requests cluster with positive sentiment -- users love the product but want it to connect with more tools. This directly informs the product roadmap. ### Brand Monitoring A marketing team exports [YouTube comments](/blog/how-to-export-youtube-comments) from their competitor's product review videos. NER extracts every brand mention. Sentiment analysis scores each mention. The result: their own brand is mentioned 47 times with an average sentiment of +0.3, while the competitor's brand appears 312 times with an average of -0.1. This data powers the next quarter's positioning strategy. ### Academic Research A researcher studying public opinion on remote work scrapes comments from 15 Reddit threads in r/antiwork and r/cscareerquestions. Topic modeling surfaces five themes: work-life balance, salary expectations, return-to-office mandates, job market anxiety, and management practices. Cross-referencing topics with timestamps shows that "return-to-office" sentiment shifted from -0.4 to -0.7 after a wave of corporate announcements -- quantifying what qualitative reading only hinted at. This complements the workflow described in our [academic research scraping guide](/blog/academic-research-scraping-guide). > "I exported over 3,000 comments from multiple subreddits with Comment Exporter, ran them through a Python pipeline with spaCy and VADER, and had a complete competitive analysis report in under two hours. Manually, that would have taken weeks." > > \-- Pendo Kessam, Market Research Consultant ## Conclusion Text analysis transforms scraped comments from a raw data dump into structured, actionable intelligence. The five techniques covered in this guide -- keyword extraction, sentiment analysis, topic modeling, n-gram analysis, and named entity recognition -- each answer a different question about your dataset, and combining them produces a comprehensive picture of what people are saying, how they feel, and who they are talking about. The workflow is straightforward: collect your data with [Comment Exporter](/scrapers/reddit-comment-scraper) (one click, CSV or JSON, 11 platforms), [clean the dataset](/blog/clean-scraped-review-data), and apply the analysis techniques that match your goals. No-code options like ChatGPT, Claude, and MonkeyLearn make text analysis accessible to anyone. Python with NLTK, spaCy, and VADER gives power users full control over repeatable pipelines. Whether you are doing [e-commerce review analysis](/blog/ecommerce-review-analysis), [Reddit market research](/blog/reddit-market-research-guide), or academic study of online discourse, text analysis is the skill that turns data collection into competitive advantage. Start with a single technique, build confidence, and layer in additional methods as your questions become more specific. Comment Exporter is rated 5.0 on the Chrome Web Store with 10,000+ weekly users. Reddit export is free. All 11 platforms: $49.99/mo or save 50% with the yearly plan at $299/year. ## Frequently Asked Questions ### What is the best text analysis technique for scraped reviews? It depends on your goal. For understanding overall customer opinion, sentiment analysis with VADER or TextBlob is the fastest starting point. For discovering what people talk about most, keyword extraction and n-gram analysis reveal the dominant topics. For grouping reviews into categories automatically, topic modeling with LDA or BERTopic works well on datasets of 500+ reviews. For identifying specific brands, products, or people mentioned in comments, named entity recognition with [spaCy](https://spacy.io/) is the right tool. Most analysts combine two or three techniques for a complete picture. ### Do I need coding skills to perform text analysis on reviews? No. Several no-code options exist for text analysis on review data. You can paste exported comments into [ChatGPT](https://chatgpt.com/) or Claude and ask for keyword extraction, sentiment scoring, or theme identification. Google Sheets formulas like COUNTIF can perform basic keyword frequency analysis. [MonkeyLearn](https://monkeylearn.com/) offers a visual interface for sentiment analysis and keyword extraction without writing code. However, Python with libraries like NLTK, spaCy, and scikit-learn gives you the most control and is worth learning if you analyze reviews regularly. ### How many reviews do I need for meaningful text analysis? For keyword extraction and sentiment analysis, even 50-100 reviews can produce useful insights. For n-gram analysis to surface reliable patterns, aim for at least 200-300 reviews. Topic modeling algorithms like LDA typically need 500 or more documents to identify coherent topics. Named entity recognition works on any dataset size since it operates at the individual comment level. The [Comment Exporter](https://chromewebstore.google.com/detail/reddit-comment-scraper/ahjjidbbielmekkaklabocljkljbmnlm) Chrome extension can export hundreds of comments from a single thread in seconds, making it easy to build datasets large enough for any text analysis technique.
