![]() ![]() Text mining refers to the automatic extraction of information and the identification of valuable and previously unknown hidden patterns from unstructured textual data. Manual processing of the huge number of documents available online is tedious, time-consuming, and error-prone. Such analysis supports various applications in different domains, such as marketing, content filtering, and search. Text analysis provides an effective way to process and utilize the most relevant data. The proposed approach achieved significant results compared to other keyword extraction techniques.Ĭurrently, social media outlets produce extremely large amounts of data. Differing from other graph-based keyword extraction approaches, the proposed method does not require user parameters during graph construction and word scoring. This approach ensures that the set of extracted keywords is comprehensive. The proposed approach relies on grouping semantically similar candidate words. The set of extracted keywords is used to assess topic diversity within the text and analyze its sentiment. Then, community detection and other measures are used to identify keywords in the text. Initially, the text is represented as a directed graph using synonym relationships. In this paper, we propose a simple unsupervised text mining approach that aims to extract a set of keywords from a given text and analyze its topic diversity using graph analysis tools. The importance of keyword extraction in text summarization, text comparisons, and document categorization has led to an emphasis on graph-based keyword extraction techniques because they can capture more structural information compared to other classic text analysis methods. In the information explosion era, keyword extraction has attracted increasing attention. ![]() Keyword extraction refers to the process of detecting the most relevant terms and expressions in a given text in a timely manner. ![]()
