PHP Summarizer

This tool will give a summary for the given text by ranking each sentence by its relevance.

• Summary output with configurable threshold - only the lines with a frequency over the threshold will be returned
• Best words extraction - most relevant keyword will be extracted (ordered by their relevance)
• Sentences split - the given text is automatically split into sentences
• Common words skip - in order to provide better results, common words are skipped based on a dictionary (only for English language provided)
• Minimal dependencies - all you need is PHP 5+ to run it (PHP 7 supported)
• Incredibly fast - in most cases, the summary is returned in less than 0.1 seconds
• Low memory usage - with regular articles less than 1MB of memory is used
• Natural language processing - much better results when using non-standard languages (e.g. Russian, Farsi, Arabic, Chinese)

PHP 5 / 7
