Mathematica offers a high level of string computation, with integrated algorithmic functions for string metrics, nearest-neighbor finding, and cluster analysis, as well as integrated HTML import, built-in natural language dictionary lookup, and an extensively curated database of word properties and connections that makes sophisticated natural language analysis immediately accessible.

• Efficient nearest-neighbor and cluster analysis for strings, using edit and other distances.
• Integrated import of HTML, with automatic scraping of tabular, textual, etc. data.
• Built-in English dictionary lookup with arbitrary regular expressions.
• Built-in database of 100,000+ words, with meanings, synonyms, and many grammatical, semantic, and morphological properties.
• Integrated parsing and output of dates and times in many formats.
• Built-in standard string hash code algorithms.
• Built-in library of sample famous text passages.
