Introduction

In this article, we will be exploring the concept of semantic-based search using text AI. We will learn how to install and use text AI to Create a semantic search engine that can return results based on the semantic meaning of words, rather than just matching keywords. We will also look at how to load and embed textual data, create an index, and query the index. So, let's dive in and discover the power of semantic-based search!

Traditional Keyword-based Search

Traditional search engines rely on keyword matching to retrieve Relevant results. This means that if You search for a specific keyword, the search engine will retrieve documents that contain that exact keyword. While this method is simple and effective in many cases, it can overlook documents that are semantically related but do not contain the exact keyword.

The Power of Semantic-based Search

Semantic-based search, on the other HAND, goes beyond keyword matching and focuses on the meaning of words. It can retrieve documents that are semantically related to the search query, even if they do not contain the exact keywords. This is achieved through machine learning algorithms that analyze the semantic structure of the text and identify relationships between words.

What is text AI?

text AI is a powerful library that enables us to perform semantic-based search and retrieval on textual data. It uses state-of-the-art language models to vectorize and embed the text, allowing us to create an index of semantic representations. With text AI, we can search this index using a query and retrieve documents that are semantically related to the query.

Installing text AI

Before we can start using text AI, we need to install it. If you're using a Python 3.7 environment, you can simply use pip to install text AI. Once installed, we can import the necessary modules and start working with text AI.

Loading and Embedding the Data

The first step in using text AI is to load our textual data and convert it into numerical vectors. We can do this by creating an embeddings object and passing in our data. The embeddings object will convert the text into embeddings, which are numerical representations of the text that capture its semantic meaning. We can then store these embeddings in a list.

Creating the Index

Once we have the embeddings for our data, we can create an index. The index is a structured data structure that allows us to efficiently search and retrieve documents based on their semantic similarity to a query. We can create the index by calling the index method on the embeddings object and passing in our embeddings data.

Querying the Index

With the index in place, we can now perform semantic-based queries on our data. We can search the index using a search query, and the index will return documents that are semantically related to the query. We can specify the number of results we want to retrieve, and the index will rank the results based on their similarity to the query.

Saving and Loading the Embeddings Model

Once we have created our embeddings and index, we can save them for future use. This is useful when we have a large corpus of data and don't want to recompute the embeddings and index each time we run our code. We can save the embeddings model using the save method on the embeddings object and load it using the load method.

Conclusion

Semantic-based search using text AI provides a powerful tool for retrieving documents that are semantically related to a query. By going beyond simple keyword matching, we can discover documents that may have been missed by traditional search algorithms. With its user-friendly interface and powerful capabilities, text AI opens up new possibilities for semantic search in various domains. So, start exploring the power of semantic-based search with text AI today!

FAQ:

Q: What is the difference between keyword-based search and semantic-based search?
A: Keyword-based search matches exact keywords in documents, while semantic-based search focuses on the meaning of words and can retrieve semantically related documents.

Q: Can text AI be used on large textual datasets?
A: Yes, text AI can handle large datasets and provides efficient indexing and querying capabilities.

Q: How do I install text AI?
A: You can install text AI using pip in a Python 3.7 environment. Simply run the command pip install text-ai.

Q: Can I use text AI to search for documents that don't contain specific keywords?
A: Yes, text AI allows you to search for documents based on their semantic meaning, even if they don't contain the exact keywords you are searching for.

Q: Can I save and load the embeddings model created by text AI?
A: Yes, text AI provides functionality to save and load embeddings models, allowing you to reuse them for future searches.
