Text mining is a burgeoning field. Various text mining approaches, especially sentiment analysis, named entity extraction and topic modeling are used by many companies to provide additional insights into unstructured data.
We have compiled this concept graph using InfraNodus to showcase some of the most interest text mining web-based applications out there. Most of these software tools are available through an API, however, some of them can also be used through the web for research purposes. Unfortunately many do not disclose the full range of text mining methods they use, however, usually it’s a combination of machine-learning and various statistical tools, such as LDA, LSA and others.
