The most common tasks are part-of-speech tagging. There is an increasing number of apps with great user interfaces, and some of them free, which enable you to enrich your corpus.Īn important step, primarily for those that build their own packages and analysis tools, is to enrich the corpus. However, some of the statistical analysis these tools offer is remarkable.

Beside Voyant, which was launched seven years ago, the other software was developed in the 1990s to early 2000s, when coding was not as widespread a skill as it is today.

Most tools that do not require coding skills are relatively old.Ī suite of free and some paid applications are available for researchers that don’t code, such as Voyant, Lexi&co, IRaMuTeQ, Hyperbase, Mallet, Orange Text and Data Mining.

Graph showing tools and packages for text mining by charge 1962-2019 In other words, the more you want to get out of your corpus, the more comfortable you need to be with R or Python in order to find and use these packages and especially if you want to apply transformers and language representation models to your dataset.
the outputs are as good if not better than some of the paid-for options and the open-source no-code options. The free and/or open-source libraries and packages such as scikit-learn, spacy, gensim, quanteda, NLTK are high performance, i.e.

More than 70% (92 out of 130) of the tools we’ve identified for text cleaning, preprocessing, enriching, and all kinds of analysis are free to use, and a handful provide free trial periods. Key takeaways Most tools are free, but high-performance tools require coding skills. We focused almost entirely on statistical, quantitative and computational analysis of text, although some of these tools could be used to explore texts for qualitative purposes.Īn infographic of text mining tools in the social sciences. In the infographic below, we identify more than 80 different apps, software packages, and libraries for R, Python and MATLAB that are used by social science researchers at different stages in their text analysis project. Others, are using platforms like IRaMuTeQ and Hyperbase that require no coding skills to run large scale text analysis projects. Meanwhile, political scientists like Justin Grimmer and colleagues are combining experimental methods, with computational text analysis to infer the features or pieces of text that are most likely to affect our voting behaviors. The improvements to the representation of text with models like BERT from Google and the OpenAI’s GPT are the talk of the town in computational linguistics since they beat a benchmark for natural language understanding faster than predicted. Researchers and developers within the public and private sectors have been making strides in this space, and especially so in the past year. Text mining techniques have become critical for social scientists working with large scale social data, be it Twitter collections to track polarization, party documents to understand opinions and ideology, or news corpora to study the spread of misinformation.
