Language Analyzer - Help


Word Frequency

Analyzes the input text and establishes the Word Frequency list, ordering the words from high frequency occurrence to low. This feature is very useful to improve the richness/quality of any text. Only after finishing the essay or other writing we realize how poor our vocabulary tends to be, and how often we use the same words.

It is also very good for catching misspellings. Let's say you wrote: "Rumpleskitkin" several times in your text. Last names are never included in spelling checkers. Only after running Word Frequency you realize that you used several wrong spellings:

word frequency

From Word Frequency you can select any word and add a synonym in the database.

Unique Words

This option also informs the Total and Unique Word Count and the Unique Word Ratio:

unique word count and ratio

 Texts with Unique Word Ratio of 0.40 or less are considered poor. Enhancing it with synonyms until 0.40 to 0.50 is recommended.

In the page about readability we provide results of a few text samples, ranging from 0.44 to 0.55. Educated people use more words than school children or foreigners that recently learnt a new language. Since repeating a concept is unavoidable, use synonyms.


Words without Synonym

As its name says, this option provides the list of all the words in the text that do not have a synonym in the database. Since they are ordered by frequency of occurrence in the text, is easy to start from the top, provide a synonym, and continue until the main words in the text are synonymized.

This feature really works for those users who buy the full version of the software, with the large synonym dictionary.

We call "Complexity Index" to the percent of words without a synonym. It is around 12% for normal texts, around 19% for technical texts, and 10% for very simple English.


Simple English uses short words. Academic or technical English tends to use more Latin-derived words. 

If your text has a very low index, it could be to childish or simple-worded. You can synonymize it in order to improve it. If your text has a very high index, consider using shorter words. 

Synonymizer calculates 4 indexes on a text: 

Average word length

Letter count.

Automated Readability Index

ARI = 4.71*chars/wds+0.5*wds/sentences-21.43

Coleman-Liau Readability Index

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

Complexity Index

See above, within "Words without Synonym".


Profane Language

The list of words considered profane is called from a button in the Profane Language Report. A percent of Profane words is calculated.

Find Slang

The list of words considered profane is called from a button in the Slang Language Report. A percent of Slang is calculated.

Present Continuous Index
