Information Retrieval (IR) refers to the process of extracting relevant and associated patterns based on a specific set of words or phrases. Many of the papers show the prediction of risk factors in these diseases. Cette technique est souvent désignée sous l'anglicisme text mining. Text Mining Techniques. Les outils de text-mining ont pour vocation d’automatiser la structuration des documents peu ou faiblement structurés. These techniques include text segmentation, summary extraction, feature selection, term association, cluster generation, topic identification, and information mapping. A significant challenge in the clustering process is to form meaningful clusters from the unlabeled textual data without having any prior information on them. As a result, it becomes a challenge for companies and organizations to store, process, and analyze vast amounts of textual data with traditional tools. Tokens represent words. Text flags are used to show the document category to represent individual documents or groups of documents, and colors are used to show density. The text can be any type of content – postings on social media, email, business word documents, web content, articles, news, blog posts, and other types of unstructured data. Data cleansing allows you to extract and retain the valuable information hidden within the data and to help identify the roots of specific words.
