Readability

Modifying your text Readability with Synonymizer

Synonymizer calculates 4 indexes on a text: 

 

line

Unique Word Ratio

Writers with poor vocabulary tend to use the same words many times in any writing. Such is the case of school children, learners of a new language and illiterate people.

The Unique Word Ratio is:        Number of different words in a text / total number of words 

Synonymizing is a good solution to increase the Unique Word Ratio. Good synonym choice will help you increase the reading level (readability) of your text to the intended audience.

Coleman-Liau Readability Index

Coleman-Liau = 5.89*chars/wds-0.3*sentences/(100*wds)-15.8

Simple English uses short words. Academic or technical English tends to use more Latin-derived words. Again, synonym replacement can provide long words and increase reading level (readability), not necessarily to make the text more difficult, but more specific and focused.

Examples:

smart - intelligent

fancy - elegant

whore - prostitute

nice - beautiful

evil - malicious

If your text has a very low index, it could be to childish or simple-worded. You can use synonyms in order to improve it. Also, you can arrange the words in longer sentences. 

If your text has a very high index, equivalent to a higher reading level or readability, consider using shorter words. Split your sentences in 2. Low reading level does not imply cheap writing.

Comment: As expected, Einstein is not very readable. Burroughs and Melville follow. I tend to use few, long words in short sentences, as most foreign English speakers.
