Here’s a quick explainer on how head tail analysis and AI can fix searches to help users find what they need.
Head queries make up the largest volume of queries and tend to be short words or phrases. Tail queries are a higher volume of fewer queries that tend to be longer words or multi-word phrases. The torso is everything else in between.
Many believe you only need to worry about the popular head queries. But head queries tend to be more topical in nature — and may represent only a small fraction of the total search queries on your site or application.
Tail queries, on the other hand, may mean missed opportunities. It could mean a typo, a number not typed correctly, or even a synonym.
Lucidworks Fusion runs offline head/tail analysis on all your queries and classifies tail distribution.
So you can see what you are missing – and fix it.
Looking at only the query analysis is only half the job. Lucidworks Fusion ingests users’ behaviors too: what they clicked on, what they didn’t, and what they rewrote. We feed these signals into Fusion to find synonyms, misspellings, and more popular “head” queries. For example, if users frequently type “manger” and “manager” in succession If “carpet” typically follows “rug” Fusion learns those are synonyms.
Head/Tail Analysis allows us to look at historical behavior and rewrite the query for greater relevance.
There’s nothing artificial about intelligence. Augmented intelligence is when AI extends human judgment instead of replacing it.
Machine learning and search engines are a incredible combination for creating powerful experiences for customers and employees.
How clustering and classification algorithms can improve the search experience for your employees and customers.
Underperforming queries aggravate everyone. Head/tail analysis stops it.
Users are constantly telling you what they like and what they don’t. Are you listening? Predict user intent by applying signals.
The best search applications index all of a company’s data so users have one unified search experience.
Personalization is about addressing people by name. Hyper-personalization is figuring out what they really want.
What if we could talk to computers in the same way we talk to people. Natural language search gets you there.
