Over the Internet, cloud computing delivers computing resources. The technology is being widely adopted in a wide range of applications and is becoming more prevalent. Growing computing power and data storage, the exponential growth of social network data, as well as modern data centers that can suffer from high maintenance costs and low utilization are mainly responsible for cloud computing's rapid growth. As well as developing reliable, cost-effective cloud-based systems. Information retrieval systems (IRS) that rely on simple words or terms consider a document to be a collection of words, referred to as a word bag. It is only the frequency of appearance of words in documents that is useful in these systems. Neither the meaning nor the context of the word are taken into account. The meaning of a word varied, however, depending on the context (polysemy). Therefore, classical IRS ignore synonymy. It does not take into account the order in which the words appear. Nevertheless, it is necessary to pay attention to the order in which multiple words appear (complex terms, compound terms). Information retrieval [IR] is the process of finding, storing, searching, and retrieving information in databases according to a user's request.
