We got the house settled into some routine now which means I can focus my attention on SlideMagic again. Following up on a blog post of 2 days ago, I made more improvements to the slide search algorithm that produces related slides:
It identifies variants of the same design (more or fewer columns or rows for example
A similar message or concept that they are trying to convey
Slides that are different but have the same visual structure as the one you initially picked
I removed the category labels in the search results (that were useful for me, but not really for a user). Instead, I am going for a single list of slides sorted by relevance without revealing what is behind that relevance. And that algorithm will get better and more accurate over time.
