AI is adept at many tasks, but reading social cues isn’t always one of them. It’s notoriously bad at understanding nuance, which results in misguided yet funny failed attempts.

That’s because it’s hard to teach machines what people really mean. Until someone builds formulas for sarcasm detection, training AI systems to detect emotions remains a mighty task. Luckily, advancements in text analysis are moving us in the right direction—a 2017 Gartner survey found that 79% of respondents already use or expect to use text analytics (full content available to Gartner clients).

What is text analysis?

Text analysis is the process of finding information from text sources, including emails and survey answers. These sources are unstructured data—that is, any data that’s not stored in a fixed format.

Text analysis involves reading unstructured data from a range of sources with the goal of finding business insights—processes your colleagues currently do by hand that you can automate for faster results. To achieve this, text analysis in businesses often takes one of five key forms:

1. Summarization: Trying to find key content across either a range of sources or a single document
2. Sentiment analysis: Assessing the tone, intent, and social context that’s relevant to a document
3. Explicative: Finding the reason for said sentiment analysis in a given document
4. Investigative: Reviewing the sources of a specific issue
5. Classification: Confirming the subject(s) that a text source discusses

As mentioned above, text-based data is unstructured by nature. Unlike databases and log files—which are strongly modeled, and therefore structured—text data doesn’t have numerical value. That makes it much tougher to find the insights you need manually.

So, text analysis software that finds the data for you within unstructured sources is a huge value-add. Technology that can find key content that you need, then investigate and summarize it saves hours of manual labor.

And since text analysis captures sentiment, you can use it for a range of business needs, from modeling intent to expediting group decisions.

To start your search, here are four free and open source text analysis tools. To earn a spot on this list, each tool’s source code must be freely available for anyone to use, edit, copy, and/or share. You can learn more about how we chose which tools to include in our methodology below:

Best for: Experienced dev teams who want an on-premise text analysis tool.

KNIME offers on-premise data analytics tools for small to large business. It uses the Apache Spark framework to let users build machine learning (ML) models to automate regression, classification, cluster analysis, and more.

KNIME’s text processing tool offers natural language processing (NLP), text mining, and information retrieval. Documentation on the six steps involved is available, as are tutorials for using custom tag sets.

But unless you’re using KNIME’s analytics platform, its text processing option will have limited value. Its support and documentation don’t surpass those of competitors, and teams who don’t work in engineering will face an especially large learning curve.

One final note:

To earn a spot on this list, each tool above needed to offer source code that’s freely available for anyone to view, edit, revise, etc. But many tools on this list, along with several more, offer even more features for paid customers.

We know that cost is a key concern when shopping for software. That said, investing in the right tools can save your business lots of money in the long run. To get started with text analysis, input some data into one of the free tools above.

Then, assess the results: Do you agree with the sentiment suggestions each tools makes? Did they help you discover any changes in sentiment that you might have missed?

If you’re impressed, it’s worth assessing BI software that has text analysis and additional features. Most software vendors offered tiered pricing plans that let you scale up as needed. And in an era where we create 2.5 quintillion bytes of data each day, having a strategy and software to manage data isn’t optional.

Gartner predicts (available to clients) that by 2020, 50% of businesses will lack the AI and data literacy skills needed to build business value. Using the right text analysis tool is a great way to stay in the fast lane.
