Abstract

In this paper, we present a novel application named Crossreading, which is derived from user’s reading process. Cross-reading is essentially a searching by document task from large-scale text corpus. The state-of-the-art approaches utilize similarity hashing to address this issue by modeling it as a high-dimensional data similarity search problem. However, most approaches only consider document’s lexical information while ignoring documents semantic information and metadata. Moreover, searching similar hash codes from massive hash codes quickly is still a major bottleneck. To address those problems, we propose a Fast Searching By Document approach, which considers the Cross-reading from the perspective of semantic similarity and time efficiency.
