基于句子嵌入的探索性搜索

Exploratory Search with Sentence Embeddings

California Polytechnic State University(加州州立理工大学)

Austin Silveria

摘要:

探索性搜索旨在通过语料库引导用户,而不是精确定位信息。我们提出了一个探索性的搜索系统的基础上,层次聚类和文档摘要使用句子嵌入。使用句子嵌入,我们将文档表示为其嵌入句子的平均值,提取包含接近此文档表示的句子的摘要,并提取接近文档表示的关键短语。为了评估我们的搜索系统,我们收集了过去一年的个人搜索历史,并报告了我们使用该系统的经验。然后,我们讨论了这种性质的探索性搜索系统的激励用例,并总结了未来工作的可能方向。

英文摘要:

Exploratory search aims to guide users through a corpus rather than pinpointing exact information. We propose an exploratory search system based on hierarchical clusters and document summaries using sentence embeddings. With sentence embeddings, we represent documents as the mean of their embedded sentences, extract summaries containing sentences close to this document representation and extract keyphrases close to the document representation. To evaluate our search system, we scrape our personal search history over the past year and report our experience with the system. We then discuss motivating use cases of an exploratory search system of this nature and conclude with possible directions of future work.
