Kategorisasi dokumen web secara otomatis berdasarkan folksonomy menggunakan multinomial naive Bayes classifier

Hendy Irawan

摘要:

Folksonomy是一个非层次的文档分类系统,它以扁平的方式对待每个类别,并且每个类别都可以由任何提交这些类别的文档的人自由输入。分类是在提交文档时自动完成的,方法是输入最适合文档的类别列表。del.icio.us://del.icio.us)站点是使用大众分类法的最流行的社会书签站点之一。大众分类法的使用虽然非常简单,但也有它的弱点,如对同一概念使用不同的标签,对不同的概念使用相同的标签,没有质量控制等。我们试图通过分析Web文档的内容,并使用多项式朴素贝叶斯算法自动分类,为这些问题提供一个解决方案。贝叶斯分类器使用一组证据和一组类来工作。通过使用样本数据训练系统,我们可以确定给定特定类别的证据的概率。贝叶斯分类器还使用类的先验概率,其可以从样本数据计算。从这些分析中,当给定由一组证据(单词)形成的新文档时,可以确定给定该文档的每个类别的概率(后验概率)。该系统使用PHP 5,Apache和MySQL实现。通过建立该系统的结论是,贝叶斯方法可以用于自动分类的文件,也可以作为一个辅助工具,人工分类。- 民间经济学采用了一种不分等级的文献分类方法,它将文献分为不同的类别,并将不同的类别划分为不同的类别。

英文摘要:

Folksonomy is a non-hierarchical document categorizing system, that treats every category in a flat manner, dan every category is entered freely by anyone who submitted a document in these categories. Categorization is done automatically at the time a document is submitted, by entering the list of categories that best fit the document. del.icio.us (http://del.icio.us) site is one of the most popular social bookmarking sites that uses folksonomy. Usage of folksonomy, although very easy, also has its weaknesses, such as use of different tags for the same concept, use of the same tag for different concepts, no quality control, etc. We try to provide a solution for some of these problems by analyzing Web documents' contents and categorizing them automatically using multinomial naive Bayes algorithm. Bayes classifier works by using a set of evidences and a set of classes. By training the system using sample data, we can determine the probability of an evidence given a particular class. Bayes classifier also uses prior probability of a class, which can be calculated from sample data. From these analysis, when given a new document which is formed by a set of evidences (words), the probabilities of each class given that document (posterior probabilities) can be determined. This system is implemented using PHP 5, Apache, and MySQL. The conclusion from building this system is that the Bayes method can be used to automatically categorize documents and also as an assistive tool for manual categorization. ----- Folksonomy merupakan metode kategorisasi dokumen yang tidak hierarkis, menyamaratakan kedudukan setiap kategori, dan judul kategori ditentukan secara bebas oleh siapa saja yang memasukkan sebuah dokumen di dalam kategori-kategori tersebut.
