How open source platforms are used for sentiment analysis?
In our in-depth guide for sentiment analysis, we laid out the three main steps of sentiment analysis: data acquisition, model selection, and analysis. Open source platforms are tools that mainly offer the third step, which is analyzing already collected data. They possess a text classifier, which tags the words or groups of words in a text as negative, positive or neutral and gives an overall sentiment score to the text.
Sentiment analysis frameworks are an application of natural language processing, and share similar concerns with the bigger NLP space. The tool’s accuracy, performance across different languages, and robustness to connect to your data source are all important and dependent on how actively the open source solution is supported.
Top open-source sentiment analysis coding packages:
The highest ranking sentiment analysis package on Github is spaCy, with 22.5k stars in Natural Language Processing. It supports more than 60 languages and has very extensive documentation. Built in mostly in Python, it is a combination of 6 different programming languages. This platform provides extensive community content to help out developers at any level, from beginners to advanced.
Another high-ranking sentiment analysis package on Github with 8.2k stars as of 2022 is Pattern, mainly in Python. Compared to spaCy, this package provides data collection options via web scrapers or integrating APIs and applying sentiment analysis on collected data as a comprehensive solution. There are more than 50 examples provided in the package, which can be a one-stop-shop solution for technical teams that are already experienced in Python.
Top low-code or no-code open-source sentiment analysis tools:
MeaningCloud is used by multiple big corporations for sentiment analysis and offers a free tier that may be available for the volume of your sentiment analysis needs. This free tier also supports API integration, which may help automate your text analysis process. Most paid sentiment analysis tools online will offer you a limited-time free trial with their full functionalities. MeaningCloud is different by providing a continuous free service with limited volume and capability, which may still be sufficient for your business needs.
2. Social Searcher:
Social Searcher specializes in social media sentiment analysis and has experience working with big corporations. Their dashboard view is particularly helpful to compare different platforms and have a crisp understanding of the overall picture of a specific keyword, which can be especially useful for marketing use cases such as tracking a hashtag of a recently launched campaign. Social Searcher offers real-time searches for free, and the dashboard is available in their paid plan. However, compared to other paid sentiment analysis tools in the market, the paid plan in 2022 seems to start at a reasonable rate.
Pros and cons of open source sentiment analysis platforms
- Mostly free or at minimal cost, especially for companies that have developer teams
- Fast to try for a business case or run a pilot with
- Open to innovation and new features through online communities
- Risk of not being compliant with security requirements, especially for big corporations
- Limited support for specific troubleshooting needs given the lack of a formal support layer
- Lack of sustainability due to multiple cases such as solution discontinuity, version upgrades, or changes in licenses and fees
- Mostly dependent on data being collected and processed separately
Bright Data’s automated web data collector scrapes the web from targeted websites and delivers the data in a clean and processed format, readily available for any existing sentiment analysis tools your business leverages. They also provide sample datasets for users who do not have a preference on the targeted websites for data collection.
