Document Search with Extractive QA

In search, your goal is to get users the answers to their questions as seamlessly as possible. The problem is that your data exists in different structures. Some data is highly structured in knowledge graphs, some in semi-structured FAQs, while other data is completely unstructured like a blog, help article, or web page. Document Search is an algorithm specifically optimized for searching long documents, to help you deliver answers to your customers.

Extractive QA, like many other parts of the Search Algorithm, uses Google's open source neural network, BERT, which is trained to understand language. In Extractive QA, a specially trained version of BERT helps to identify the excerpts from long documents that best answer the user's question. If it finds a good answer in the text, the algorithm displays it as a featured snippet.

In addition to providing a direct answer at the top of the page, Extractive QA also highlights relevant context as in-line snippets on each result down the page. These snippets provide a great search experience and help searchers find the best answers to their queries, even faster.

Unstructured data can be found across a number of different environments or sites. Places like your blog, your support site, or your press release hub may host a ton of great content that just isn't set up for modern search. Connectors like the Yext Crawler or Zendesk Connector can pull long-form unstructured data from apps or sources like your website so that you can build out your Knowledge Graph and use it to start powering Search!
