ExtremeReader: An Interactive Review Summary Explorer

The rise of e-commerce has spurred extensive growth in the volume of user reviews. Since reading reviews is a tedious and time-consuming process, automatic summarization systems have received significant attention in the data mining, machine learning, and natural language processing (NLP) communities.

Despite extensive research in this area, current state-of-the-art automatic text summarization systems still suffer from two significant limitations:

  1. They only provide static summaries that cannot be tailored to specific user needs.
  2. They do not explain or let users explore crucial aspects of the generated summary.

We developed ExtremeReader, an interactive review summary explorer, to address these obstacles:

  1. ExtremeReader generates both a structured and abstractive summarization that are easier to interpret. To accomplish the latter, ExtremeReader uses the breadth-first search algorithm method for opinion serialization and a seq2seq model to generate the output from this input sequence of opinions.
  2. It also allows users to explore and see explanations of these summaries by drilling down or up to the desired level of granularity. Users can even see the sentence from which the opinion features were extracted.

ExtremeReader is the first system with these capabilities. We believe that this system holds vast potential to transform how we interact with and understand user reviews at scale.

The Megagon Labs team had the honor of presenting ExtremeReader’s advantages through a demonstration on a public YELP restaurant review corpus and a private hotel review dataset at World Wide Web (WWW) 2020. WWW is an international conference that highlights how computer science, deep learning, and other technological fields impact the future of the internet.
