established news sites use click bait titles to drive additional traffic to
their sites and generate additional impressions.<p>Goal is to see how article titles and actual content of article differ from each
other and see if titles are clickbaited.<h2 id=preparing-and-cleaning-data>Preparing and cleaning data</h2><p>For this example I opted to just use RSS feed from a new website and decided to
go with <a href=https://www.theguardian.com>The Guardian</a> World news. While this gets
us limited data (~40) articles and also description (actual content) is trimmed
this really doesn't reflect the actual article contents.<p>To get better content I could use web scraping and use RSS as link list and
fetch contents directly from website, but for this simple example this will
suffice.<p>There are couple of requirements we need to install before we continue:<ul><li><code>pip3 install feedparser</code> (parses RSS feed from url)<li><code>pip3 install vaderSentiment</code> (does sentiment polarity analysis)<li><code>pip3 install matplotlib</code> (plots chart of results)</ul><p>So first we need to fetch RSS data and sanitize HTML content from description.<pre tabindex=0 style=background-color:#fff><code><span style=display:flex><span><span style=color:#00f>import</span> re
</span></span><span style=display:flex><span><span style=color:#00f>import</span> feedparser
</span></span><span style=display:flex><span>
</span></span><span style=display:flex><span>feed_url = <span style=color:#a31515>"https://www.theguardian.com/world/rss"</span>
</span></span><span style=display:flex><span>feed = feedparser.parse(feed_url)
</span></span><span style=display:flex><span>
</span></span><span style=display:flex><span><span style=color:green># sanitize html</span>
</span></span><span style=display:flex><span><span style=color:#00f>for</span> item <span style=color:#00f>in</span> feed.entries:
</span></span><span style=display:flex><span> item.description = re.sub(<span style=color:#a31515>'<[^<]+?>'</span>, <span style=color:#a31515>''</span>, item.description)
</span></span></code></pre><h2 id=perform-sentiment-analysis>Perform sentiment analysis</h2><p>Since we now have cleaned up data in our <code>feed.entries</code> object we can start with
performing sentiment analysis.<p>There are many sentiment analysis libraries available that range from rule-based
sentiment analysis up to machine learning supported analysis. To keep things
simple I decided to use rule-based analysis library
<a href=https://github.com/cjhutto/vaderSentiment>vaderSentiment</a> from
<a href=https://github.com/cjhutto>C.J. Hutto</a>. Really nice library and quite easy to
use.<pre tabindex=0 style=background-color:#fff><code><span style=display:flex><span><span style=color:#00f>from</span> vaderSentiment.vaderSentiment <span style=color:#00f>import</span> SentimentIntensityAnalyzer
</span></span><span style=display:flex><span>analyser = SentimentIntensityAnalyzer()
</span></span><span style=display:flex><span>
</span></span><span style=display:flex><span>sentiment_results = []
</span></span><span style=display:flex><span><span style=color:#00f>for</span> item <span style=color:#00f>in</span> feed.entries:
</span></span><span style=display:flex><span> sentiment_title = analyser.polarity_scores(item.title)
</span></span><span style=display:flex><span> sentiment_description = analyser.polarity_scores(item.description)
</span></span><span style=display:flex><span> sentiment_results.append([sentiment_title[<span style=color:#a31515>'compound'</span>], sentiment_description[<span style=color:#a31515>'compound'</span>]])
</span></span></code></pre><p>Now that we have this data in a shape that is compatible with matplotlib we can
plot results to see the difference between title and description sentiment of an
article.<pre tabindex=0 style=background-color:#fff><code><span style=display:flex><span><span style=color:#00f>import</span> matplotlib.pyplot <span style=color:#00f>as</span> plt
</span></span><span style=display:flex><span>
</span></span><span style=display:flex><span>plt.rcParams[<span style=color:#a31515>'figure.figsize'</span>] = (15, 3)
</span></span><span style=display:flex><span>plt.plot(sentiment_results, drawstyle=<span style=color:#a31515>'steps'</span>)
</span></span><span style=display:flex><span>plt.title(<span style=color:#a31515>'Sentiment analysis relationship between title and description (Guardian World News)'</span>)
</span></span><span style=display:flex><span>plt.legend([<span style=color:#a31515>'title'</span>, <span style=color:#a31515>'description'</span>])
</span></span><span style=display:flex><span>plt.show()
</span></span></code></pre><h2 id=results-and-assets>Results and assets</h2><ol><li>Because of the small sample size further conclusions are impossible to make.<li>Rule-based approach may not be the best way of doing this. By using deep
learning we would be able to get better insights.<li><strong>Next step would be to</strong> periodically fetch RSS items and store them over a
longer period of time and then perform analysis again and use either machine
learning or deep learning on top of it.</ol><figure><img src=/posts/sentiment-analysis/guardian-sa-title-desc-relationship.png alt="Relationship between title and description"></figure><p>Figure above displays difference between title and description sentiment for
