摘要:

我们报告了一系列的实验,不同的语义模型上的各种统计模型提取文本摘要。虽然统计模型可以更好地捕获文本周围的单词共现和分布,但它们无法检测句子/单词作为一个整体的上下文和意义。语义模型帮助我们更好地洞察句子的上下文。我们展示了如何调整不同模型之间的权重可以帮助我们在各种基准测试中取得显着的结果。在给定的语料库上,进一步学习语义模型中使用的预训练向量可以在性能上提供额外的尖峰。在不同的统计模型之间使用加权技术也进一步改进了我们的结果。对于统计模型,我们使用了TF/IDF,TextRANK,Jaccard/Cosine相似性。对于语义模型,我们使用了基于WordNet的模型,并提出了两个模型的基础上手套向量和Facebook的Infersent。我们在DUC 2004数据集上测试了我们的方法,生成了100字的摘要。我们已经讨论了系统,算法,分析,并提出和测试可能的改进。使用ROUGE评分与其他汇总器进行比较。

英文摘要:

We report a series of experiments with different semantic models on top of various statistical models for extractive text summarization. Though statistical models may better capture word co-occurrences and distribution around the text, they fail to detect the context and the sense of sentences /words as a whole. Semantic models help us gain better insight into the context of sentences. We show that how tuning weights between different models can help us achieve significant results on various benchmarks. Learning pre-trained vectors used in semantic models further, on given corpus, can give addition spike in performance. Using weighing techniques in between different statistical models too further refines our result. For Statistical models, we have used TF/IDF, TextRAnk, Jaccard/Cosine Similarities. For Semantic Models, we have used WordNet-based Model and proposed two models based on Glove Vectors and Facebook's InferSent. We tested our approach on DUC 2004 dataset, generating 100-word summaries. We have discussed the system, algorithms, analysis and also proposed and tested possible improvements. ROUGE scores were used to compare to other summarizers.
