摘要

大多数信息(超过80%)以文本形式存储,文本挖掘是文本分类过程中非常重要的一步,在阿拉伯语中尤其如此。该研究的目的是使用高级性能指标根据特定类别对阿拉伯文本进行分类。我们使用Data Templates作为管理和组织Apache Spark的平台,以解决大数据挑战。Apache Spark提供了几个集成的语言api。使用NLP库进行文本处理。该数据的预处理分为几个步骤,即根据词与词之间的间距将词分离成一个文本,清理文本中不需要的词,恢复词的词根,其中特征选择过程是关键步骤。在文本分类。它是一种预处理技术。在本文中,确定使用哪些TF属性以及每个特征在文档中出现的频率的一种方法是,它们考虑特征选择过程的第一级。然后我们使用TF-IDF来确定特征在文档中的重要程度,这是预处理结果文本分类的最后一步。结果评估使用先进的性能指标,如准确性,精密度和召回。准确率达到96.94%。本文的主要目标是快速准确地对基础文本进行分类,根据结果,只要特征大小合适,最先进的技术由于其合理的可靠性和完善的修剪水平而优于其他通过率方法。

Text Classification Using Convolutional Neural Networks
Most of the information (more than 80%) is stored as text, and text mining is a very important process as it is an initial step in the process of text classification, and this is especially the case in the Arabic language. The Aim of The Study is to classify Arabic texts according to specific categories using advanced performance indicators We used Data Templates as a platform for managing and organizing Apache Spark to solve big data challenges. Apache Spark offers several integrated language APIs. nlp lib was used for text processing. The data is pre-processed through several steps, namely separating the words into one text on the basis of the space between words, cleaning the text of unwanted words, restoring the words to their roots, as well as the feature selection process is a critical step. in text classification. It is a preprocessing technology. In this paper, one way to determine which TF attributes are used how often each feature appears in the document is that they consider the first level of the feature selection process. Then we use TF-IDF to determine the significance of the feature in the document, and this is the last step in the preprocessing Outcomes Text classification . Results were evaluated using advanced performance indicators such as accuracy, Precision and recall. A high accuracy of 96.94% was achieved.The main objective of this paper is to classify basic texts quickly and accurately, according to the results as long as the feature size is suitable, the most advanced technology is superior to other pass rate methods due to the reasonable reliability and perfect pruning level.
