How open source platforms are used for sentiment analysis?

Exploring the world of sentiment analysis? Awesome! Let’s break down how open source platforms play a crucial role in this process.


In our comprehensive sentiment analysis guide, we outlined three key steps: data acquisition, model selection, and analysis. Now, open source platforms mainly shine in the third step – the analysis part. Here’s the scoop: these platforms come armed with a text classifier. This nifty tool goes through your text, tagging words or groups of words as negative, positive, or neutral. Plus, it dishes out an overall sentiment score for the entire text.


Think of sentiment analysis frameworks as the cool cousins of natural language processing (NLP). They share similar concerns but focus specifically on deciphering sentiments. When you’re exploring open source solutions, keep a keen eye on a few key factors: accuracy, multilingual performance, and the platform’s ability to seamlessly connect with your data source. The magic really happens when these solutions are actively supported, ensuring top-notch accuracy and reliability. Ready to dive into the sentiment analysis adventure? Let those open source platforms do the heavy lifting for you!

Let's break down the pros and cons of open source sentiment analysis platforms


  • Cost-Effective: Open source platforms are often free or available at minimal cost, making them an attractive option, particularly for companies with in-house developer teams.

  • Quick Implementation: Swift deployment allows businesses to swiftly try out or pilot sentiment analysis for specific use cases, providing a fast route to assess the technology’s value.

  • Innovation and Community Support: Open source platforms thrive on innovation and continually evolve with the help of online communities. This collaborative environment often leads to the introduction of new features and improvements.


  • Security Compliance Risk: Especially concerning for large corporations, there is a risk of non-compliance with stringent security requirements. Open source platforms may lack the robust security measures needed for handling sensitive corporate data.

  • Limited Support: The absence of a formal support layer may result in limited assistance for specific troubleshooting needs. Companies relying on open source solutions may face challenges in obtaining dedicated support.

  • Sustainability Concerns: Open source platforms may face sustainability issues due to factors such as solution discontinuity, version upgrades, or changes in licences and fees. This instability can pose challenges for businesses relying on these platforms in the long term.

  • Dependency on Separate Data Processing: Open source sentiment analysis platforms are often dependent on data being collected and processed separately. This adds complexity to the overall workflow, potentially requiring additional resources for data handling.


In weighing the pros and cons, businesses should carefully consider their specific needs, security requirements, and long-term sustainability goals before opting for open source sentiment analysis solutions.
