基于关键词属性的话题分析

Enhance Topics Analysis based on Keywords Properties

Accenture(埃森哲)

Antonio Penta

摘要:

主题建模是一种用于探索和检索文档集的最流行的文本分析技术。由于没有一个黄金标准的主题列表来比较每个语料库,主题模型算法的评估仍然是一个非常具有挑战性的任务。在这项工作中,我们提出了一个特异性得分的基础上,能够选择最翔实的主题的关键字属性。这种方法可以帮助用户专注于信息量最大的主题。在实验中,我们表明,我们能够压缩的国家的最先进的主题建模结果的不同因素的信息损失是远远低于解决方案的基础上,最近的一致性得分在文献中提出的。

英文摘要:

Topic Modelling is one of the most prevalent text analysis technique used to explore and retrieve collection of documents. The evaluation of the topic model algorithms is still a very challenging tasks due to the absence of gold-standard list of topics to compare against for every corpus. In this work, we present a specificity score based on keywords properties that is able to select the most informative topics. This approach helps the user to focus on the most informative topics. In the experiments, we show that we are able to compress the state-of-the-art topic modelling results of different factors with an information loss that is much lower than the solution based on the recent coherence score presented in literature.
