Lucidworks Fusion Smart Answers

Fusion 4.2.5 introduces Lucidworks Fusion Smart Answers, an AI-driven question answering system which combines the power of Solr and neural dense vectors to recommend solutions to users.

Smart Answers incorporates semantic and contextual information into query understanding to generate recommendations from frequently asked questions (FAQ) records. If FAQ data is not availalbe, Smart Answers can adopt a "cold start" methodology, which uses our word vector (Word2vec) training module to learn about the vocabulary in the search results.

Example use cases:

Call Center or IT Support

Fusion Smart Answers can be implemented on a help or contact us page, or embedded in a virtual assistant, to reduce the workload for call centers or IT support. Smart Answers can also increase efficiency for the customer support team by helping them find answers to problems that have already been solved.

E-commerce

Smart Answers can help shoppers answer their questions about products, search user manuals for solutions to their problems, or point them to relevant discussions other customers have had about the product.

Improved Search for Long Queries

With the cold start solution, Smart Answers uses various word embedding methods to capture semantic and contextual information for long queries or natural language processing.

New Pipeline Stages

To support Lucidworks Fusion Smart Answers, Fusion 4.2.5 introduces several new pipeline stages. These stages are documented in detail in Smart Answers.
