I recently wrote a paragraph, and I think there is nothing wrong with the english. But aftet a quality assesmemt, it was found lack quality, it might also because of grammar.
Here is the paragraph :
Twitter is an example of a compact social media, used by influential people (to express ideas, statements) and companies or businesses (to promote or market their products). Large data of twitter, in the form of tweets that contain at least a text, an image, or a video, has been around since 2006. Tweets sent by a company might represent the behavior of that company.
What and how to improve? Thanks.
