Fake Search?

Enterprise search was once easy. It was often bad - but understanding the results was pretty easy. If the query term(s) were in the document, it was there in the results. Period. The more times the terms appeared, the higher the result appeared in the result list. And when the user typed a multi-term query, documents with all of the terms displayed higher in the result list than those with only some of the terms.

And some search platforms could 'explain' why a particular document was ranked where it was. Those of us who have been in the business a while may remember the Verity Topic and Verity K2 product lines. One of the most advanced capabilities in these was the 'explain' function. It would reverse engineer the score for an individual document and report the critical 'why' the selected document was ranked as it was.

"People Like You"

Now, search results are generally better, but every now and then, you’ll see a result that surprises you, especially on sites that are enhanced with machine learning technologies. A friend of mine tells of a query she did on Google while she was looking for summer clothes, but the top result was a pair of shoes. She related her surprise: "I asked for summer clothes, and Google shows me SHOES?".  But, she admitted, "Those shoes ARE pretty nice!"

How did that happen? Somewhere, deep in the data Google maintains on her search history, it concluded that "people like her" purchased that pair of shoes.

In the enterprise, we don't have the volume of content and query activity of the large Internet players, but we do tend to have more focused content and a narrower query vocabulary. ML/AI tools like MLLib, part of both Mahout and Spark, can help our search platforms generate such odd yet often relevant results; but these technologies are still limited when it comes to explaining the 'why' for a given result. And those of us who still exhibit skepticism when it comes to computers, that capability would be nice.

Are you using or planning to implement) ML-in-search? A skeptic? Which camp you're in? Let me hear from you! miles.kehoe@ideaeng.com.

Lucidworks expands focus in new funding round

Lucidworks, the commercial organization with the largest pool of Solr committers, announced today a new funding round of $50M US from venture firms Top Tier Capital Partners and Silver Lake Waterman, as well as additional participation from existing investors Shasta Ventures, Granite Ventures, and Allegis Capital.

While a big funding round for a privately held company isn't uncommon here in 'the valley', what really caught my attention is where and how Lucidworks will use the new capital. Will Hayes, Lucidworks' CEO, intends to focus the investment on what he calls "smart data experiences" that go beyond simply artificial intelligence and machine learning. The challenge is to provide useful and relevant results by addressing what he calls "the last mile" problem in current AI:  enabling mere mortals to find useful insights in search without having to understand the black art of data science and big data analysis. The end target is to drive better customer experiences and improved employee productivity.

A number of well-known companies utilize Lucidworks Fusion already, many along with AI and ML tools and technologies. I've long thought that to take advantage of 'big data' like Google,  Amazon, and others do, you needed huge numbers of users and queries to confidently provide meaningful suggestions in search results.  While that helps, Hayes explained that smaller organizations will be able to benefit from the technology in Fusion because of both smaller and more focused data sets, even with a smaller pool of queries. With the combination of these two characteristics, Lucidworks expects to deliver many of the benefits of traditional machine learning and AI-like results to enterprise-sized content. It will be interesting to see what Lucidworks does in the next several releases of Fusion!
