Luhn came up with the concept based on the understanding that important words, which contain the majority of the document’s content, are neither common nor uncommon. Luhn’s technique selects relevant phrases for the summary based on their frequency of occurrence in the text. Luhn first studied the notion of automated summarizing in the late 1950s. A method to the issue of summary of many documents that is based on search is presented in this study. Many various approaches and assumptions have been used in the past to create effective summaries of numerous publications. Humans are costly, and every material that is to be summarized must be first reviewed by a person. However, since it involves a comprehension of natural language as well as an understanding of what is being summarized, this is a process generally handled by people. Historically, summaries of texts have been used to communicate the most important information from one or many sources to a single audience.

It is also becoming more popular in the business sector, with applications like as BT’s ProSum (for the telecommunications industry), Oracle’s Context (for text database data mining), and filters for web-based information retrieval all demonstrating this. Text summarization is recognised as a critical study topic by various organisations, including DARPA (United States), the European Community, and the Pacific Rim. It is the process of selecting the most significant information from a source or from a variety of sources in order to decrease the quantity of information in a textual document while retaining the most important information and producing a short summary of the most relevant information. IntroductionĪs the internet and online information services continue to expand in popularity, there is an enormous quantity of information accessible, which may lead to an issue known as “information overload.” As a result, text summarizing that is automated is necessary. The proposed approach shows promising results compared to the other existing techniques. Weight formula includes features such as TFIDF, phrase position, and construction of lexical chain to represent the semantic relations between words using WordNet. Our proposed approach of crucial phrase extraction is based on identifying candidate phrases from the news articles and choosing the highest weight candidate phrase using the weight formula. Keyphrases can be a single word or a combination of more than one word representing the news article’s significant concept. Then, extracted relevant content is used for the keyphrase extraction from the news articles. After those important contents have been extracted from the correctly classified newscast web pages. The findings demonstrate that it performs much better than the other two. A comparison is also made between the Naive Bayes classifier and the SMO and J48 classifiers for the same dataset. The classifier was then used to differentiate between the two groups. Using the Naive Bayes classifier for classification, news websites were distinguished from nonnews web pages by extracting content, structure, and URL characteristics. Because of the content duplication, the news summarization system, on the other hand, is unable to cope with multidocument news summarizations well. Multidocument summarization generates summaries from a large number of source papers that are all about the same subject or are about the same event. As research advanced, mainly due to the vast quantity of information available on the internet, the concept of multidocument summarization evolved. The summarizing of a single document generates a summary of a single paper. The first work in summarizing was done using a single-document summary as a starting point. The current trend in text summarizing, on the other hand, is increasingly focused on the area of news summaries. This method also aids users in quickly grasping the fundamental notions of information sources. Text summarizing may be described as automatically constructing a summary version of a given document while keeping the most important information included within the content itself. In particular, within the past two decades, many attempts have been undertaken by researchers to provide robust, useful summaries of their findings. Among the many uses of natural language processing, text summarization has emerged as a critical component in information retrieval. In recent times, text summarization has gained enormous attention from the research community.
