Semantic Search for Beginners

Have you ever wondered how some websites seem to read your mind, presenting exactly what you’re looking for before you even finish typing? That’s not magic—that’s semantic search. While it sounds like something out of a sci-fi movie, semantic search is the wizardry behind making our online shopping and browsing experiences smarter and more intuitive. So, grab your wizard hat, because we’re diving into the fascinating world of semantic search and AI-generated embeddings!

The Invisible Hand of AI

At the heart of semantic search lies a complex coordinate system born from training large language models (LLMs). Imagine this as a giant, invisible map where every concept, emotion, and item you can think of is plotted. While incomprehensible to mere mortals, this map helps AI understand and relate different pieces of information with incredible accuracy. Essentially, it’s like having an omniscient librarian who knows how everything in the world is connected.

Why should you care about this? Because it means that websites using semantic search can deliver more relevant results, quicker. No more sifting through pages of unrelated products or articles. The AI does the heavy lifting, so your users find what they need almost magically, boosting their satisfaction—and your sales.

Everything is Connected

In this vast semantic space, everything is related to everything else. Let’s start with a practical example from our trusty general store, "Barn Delights," which sells just twelve products. Here's an overview of our small but mighty inventory:

Our store has products divided into three categories: Cleaning, Garden, and Grocery. Each category has specific items, which are color-coded for convenience.

• Cleaning: Window Cleaner (blue), Sponge (green), Mop (red)
• Garden: Watering Can (blue), Fertilizer (green), Planter (red)
• Grocery: Blueberries (blue), Asparagus (green), Apple (red), Sports Drink (blue), Frozen Peas (green), Pasta Sauce (red)

Now, let’s dive into the magical world of embeddings.

Embeddings: The DNA of Semantic Search

Embeddings are the core of semantic search. Think of them as the DNA of words and concepts, uniquely encoding information into a form that AI can understand. For our store, we create embeddings using the text-embedding-3-large model with 2048 dimensions. These embeddings are essentially vectors—long strings of numbers that capture the essence of each product's description.

Imagine you’re reading the description of a fresh red apple: "This fresh red apple is perfect for snacking or cooking. Packed with vitamins and fiber, it is a healthy choice." The AI converts this text into a vector, a series of 2048 floating-point numbers that uniquely represent this apple in the semantic space. This might sound complex, but it’s what allows AI to understand and relate this apple to other items and concepts.

Unrelated Example: From Mona Lisa to Floor Scrubbing

To illustrate how everything is connected in this semantic space, let’s take a fun and seemingly unrelated example. We’ll see how our store’s products relate to the Mona Lisa. Yes, you read that right—the Mona Lisa.

Surprisingly, items like pasta sauce and mop have varying degrees of similarity to the Mona Lisa. While it might seem odd, this demonstrates how interconnected our world is in the semantic space. The real magic happens when we focus on more practical examples relevant to everyday shopping.

Scrubbing Floors: A Case Study

Imagine you're looking for products to scrub your floors. Instead of manually searching for cleaning supplies, semantic search can make intelligent jumps. Here’s a chart showing the distance of various products from the phrase "scrub my floors."

As expected, products like window cleaner, mop, and sponge are much more closely related to this context. You wouldn’t scrub floors with blueberries or frozen peas, but window cleaner, mop, and sponge? You bet! This relevance is crucial for providing a delightful user experience. It’s like having a personal shopper who knows exactly what you need.

The Semantic Magic of Vantage

This is where Vantage comes in. As a leading discovery-as-a-service vendor, Vantage uses the power of AI-generated embeddings to make these connections. By simply uploading your catalog, you can create a semantic space where everything is related, and relevant items are just a click away.

Diving Deeper: Urban Homesteading and Beyond

To see semantic search’s power in action, let's explore another scenario: urban homesteading. For those unfamiliar, urban homesteading involves self-sufficiency practices in an urban setting, such as growing your own food or composting.

When you search for items related to urban homesteading, semantic search provides results like planting beds, fertilizer, and watering cans. This intuitive jump helps users quickly find what they need to start their homesteading journey. Here’s a detailed look at how our store’s products relate to this concept:

These items are essential for any urban homesteader, showing how semantic search aligns product offerings with user intent.

Dessert Pies for Birthdays

Let's sweeten the deal with another example. Say you’re looking for dessert pies for birthdays. Semantic search helps find the most relevant ingredients or items that could make up a delicious birthday dessert.

Blueberries and apples are top contenders. These results make sense because these fruits are commonly used in pies. This ability to connect user queries with the most relevant items enhances the shopping experience, making it easier for users to find what they need quickly.

Why Should You Care?

By now, you might be wondering why semantic search should be on your radar. The answer is simple: it revolutionizes the user experience. By understanding the context, desires, and circumstances of your users, semantic search can present the most appropriate items your brand has to offer. Whether it’s fashion, camping gear, recipes, or articles, this technology helps users find what they need faster and more accurately.

This not only improves user satisfaction but also increases average cart value and creates cross-sell and upsell opportunities. Users are more likely to add additional items to their carts when they find exactly what they’re looking for with minimal effort.

The Vantage Advantage

Vantage makes it easy to leverage this power. By uploading your catalog, you get access to these amazing abilities without needing to program keywords. The AI handles the complexity, delivering relevant results based on user intent, circumstance, and context.

Let’s break down how this works with a few more examples, illustrating the seamless experience provided by semantic search.

Fashion and Style

Consider a user looking for a new outfit for a summer wedding. Instead of typing in specific keywords, they can simply describe what they’re looking for: “I need a stylish, comfortable dress for a summer wedding.” The semantic search engine, powered by Vantage, understands this request and pulls up the most relevant items from the catalog, such as dresses, accessories, and shoes that match the description. This makes shopping not only faster but also more enjoyable for the user.

Camping Trips

Now imagine planning a camping trip. Users might search for “gear for a weekend camping trip.” The semantic search engine interprets this query and presents a range of items like tents, sleeping bags, and portable stoves. This holistic approach ensures that users find everything they need for their trip in one place, increasing the likelihood of them purchasing multiple items.

The Power of Context

One of the most significant advantages of semantic search is its ability to understand and leverage context. This means that the search engine doesn’t just look at isolated keywords but understands the broader meaning behind user queries.

For example, when searching for “recipes for a family dinner,” the semantic search engine will consider the context of “family dinner” and prioritize recipes that are suitable for larger groups, easy to prepare, and likely to be enjoyed by a variety of ages. This contextual understanding makes search results more relevant and useful.

Making the Magic Work for You

You can harness the power of semantic search by integrating it into your website with Vantage. Here’s how you can get started:

1. Create a Vantage Account: Sign up for a Vantage account to access their discovery-as-a-service platform.
2. Upload Your Catalog: Simply upload your product catalog to Vantage. This will allow the AI to create embeddings for each item, making them searchable in the semantic space.
3. Explore the Magic: Once your catalog is uploaded, you can start exploring the power of AI embeddings and semantic jumps. Try out various queries and see how the search results align with user intent.
