Text simplification

Text simplification is an operation used in natural language processing to modify, enhance, classify or otherwise process an existing corpus of human-readable text in such a way that the grammar and structure of the prose is greatly simplified, while the underlying meaning and information remains the same. Text simplification is an important area of research, because natural human languages ordinarily contain large vocabularies and complex compound constructions that are not easily processed through automation. In terms of reducing language diversity, semantic compression can be employed to limit and simplify a set of words used in given texts. A recent approach involves automatically simplifying text by converting it into Basic English; which has a vocabulary of only 1,000 words that are also used to describe in footnotes the meaning of 30,000 words from The Basic Dictionary of Science.

Example

Text Simplification is illustrated with an example from Siddharthan (2006). The first sentence contains two relative clauses and one conjoined verb phrase. A text simplification system aims to simplify the first sentence to the second sentence.

“The ability to simplify means to eliminate the unnecessary so that the necessary may speak”
