摘要:

本文对基于SPPIM的文本分类方法进行了研究,实验表明,在20个新闻组、路透社52和WebKB三个国际标准文本数据集上,SPPIM方法的文本分类性能与SGNS方法相当,甚至优于SGNS方法。与SGNS相比,虽然SPPMI提供了更好的解决方案,但在文本分类任务上并不一定优于SGNS。基于我们的分析,SGNS在分解过程中考虑了权重计算,因此在一些标准数据集上比SPPIM具有更好的性能。受此启发,本文在SPIM模型的基础上提出了一种WL-SPIM语义模型,实验表明,与LDA、SGNS和SPIM方法相比,WL-SPIM方法在文本分类任务中具有更好的分类效果和更高的可扩展性。

英文摘要:

In this paper, we explore SPPIM-based text classification method, and the experiment reveals that the SPPIM method is equal to or even superior than SGNS method in text classification task on three international and standard text datasets, namely 20newsgroups, Reuters52 and WebKB. Comparing to SGNS, although SPPMI provides a better solution, it is not necessarily better than SGNS in text classification tasks. Based on our analysis, SGNS takes into the consideration of weight calculation during decomposition process, so it has better performance than SPPIM in some standard datasets. Inspired by this, we propose a WL-SPPIM semantic model based on SPPIM model, and experiment shows that WL-SPPIM approach has better classification and higher scalability in the text classification task compared with LDA, SGNS and SPPIM approaches.
