TALL (Text Analysis for ALL) is an R Shiny application for exploring, modelling, and visualizing textual data. It’s aimed at researchers who need a graphical environment for natural language processing tasks, covering the workflow from data import and cleaning through to statistical analysis, interpretation, and reporting.
The application is designed for work with collections such as research articles, social media posts, survey responses, customer reviews, legal documents, and literary texts. It brings together text mining, linguistic annotation, topic modelling, sentiment analysis, and interactive visual exploration in a reproducible R-based workflow.
This is free and open source software.
Key Features
- Imports plain text, CSV, Excel, PDF, and Biblioshiny export files.
- Offers tokenization, lemmatization, part-of-speech tagging, dependency parsing, and special entity detection.
- Includes corpus statistics, lexical richness measures, TF-IDF rankings, Zipf’s law plots, and word clouds.
- Provides keyness analysis, KWIC concordance, correspondence analysis, co-occurrence networks, thematic maps, and word embeddings.
- Supports LDA, CTM, and STM topic modelling with model selection metrics and diagnostics.
- Includes lexicon-based polarity detection, emotion analysis, syntactic complexity metrics, and SVO triplet extraction.
- Exports analyses to Excel workbooks and plots to high-resolution PNG images.
