The Text Analysis Tool is a free web application that analyzes text with natural language processing (NLP) techniques. It lists the top words, phrases, and named entities in your text, along with the verbs and nouns it finds.
Text Analysis Tool features
- Preprocessing: The tool converts the input text to lowercase, removes stopwords, and filters out numbers.
- N-gram generation: The tool creates unigrams (single words), bigrams (pairs of words), and trigrams (triplets of words), and counts how often each occurs.
- TF-IDF calculation: The tool calculates Term Frequency-Inverse Document Frequency (TF-IDF) scores for the words in your text.
- Part-of-speech (POS) tagging: The tool labels words as verbs or nouns based on their endings, and counts how often each appears.
- Named entity recognition (NER): The tool extracts capitalized words, such as names of people, organizations, or locations, and groups consecutive capitalized words into one entity.
- Top N analysis: The tool lists the 10 most frequent or highest-scoring unigrams, bigrams, trigrams, verbs, nouns, and named entities.
