Mohammad Moradi, Elham Ghanbari, Mehrdad Maeen, Sasan Harifi

摘要:

在信息量日益增加的今天,其呈现的重要性也日益增加。互联网已经成为用户和他们最喜欢的主题的主要信息来源之一。它还提供了获取更多信息的途径。了解这些信息对于为用户提供最佳的信息资源集非常重要。内容提供方现在需要一种精确而有效的方法来检索新闻,而需要最少的人工帮助。数据采掘已经导致了用于检测相关和不相关文档的新方法的出现。虽然文件之间的概念关系可以忽略不计,但重要的是要向用户提供有用的信息和相关内容。提出了一种基于特征组合的信息检索方法。除了引入这种新方法外,我们还提出了一个数据集,通过识别文档中最常用的关键字,并使用最合适的文档来帮助他们丰富词汇。然后,使用所提出的方法,文本分类技术,评价标准和排名算法,数据进行了分析和检查。评价结果表明,使用组合特征的方法提高了质量和效率的排名效果。

英文摘要:

Nowadays, according to the increasingly increasing information, the importance of its presentation is also increasing. The internet has become one of the main sources of information for users and their favorite topics. It also provides access to more information. Understanding this information is very important for providing the best set of information resources for users. Content providers now need a precise and efficient way to retrieve news with the least human help. Data mining has led to the emergence of new methods for detecting related and unrelated documents. Although the conceptual relationship between documents may be negligible, it is important to provide useful information and relevant content to users. In this paper, a new approach based on the Combination of Features (CoF) for information retrieval operations is introduced. Along with introducing this new approach, we proposed a dataset by identifying the most commonly used keywords in documents and using the most appropriate documents to help them with the abundance of vocabulary. Then, using the proposed approach, techniques of text categorization, evaluation criteria and ranking algorithms, the data were analyzed and examined. The evaluation results show that using the combination of features approach improves the quality and effects on efficient ranking.
