## **What is [Semantic Search](http://www.edenai.co/feature/semantic-search?referral=best-semantic-search-2023)?**

Semantic Search API refers to a type of search that uses Natural Language Processing (NLP) and Machine Learning algorithms to understand the meaning behind a user's query, rather than just searching for matching keywords. It will take into account the context, intent, and relationships between words to provide more relevant and accurate search results. In other words, it focuses on the user's intent rather than just the specific words used in the query.

## **Semantic Search APIs uses cases**

You can use Semantic Search in numerous fields, here are some examples of common use cases:

- **E-commerce**: improve product search results by understanding the intent of users and returning more accurate product recommendations.
- **Healthcare**: help medical professionals find relevant research and clinical trial data quickly and easily.
- **News and media**: analyze news articles and provide more targeted search results to users.
- **Legal**: help legal professionals quickly find relevant cases, statutes, and other legal documents.
- **Education**: help students and researchers find relevant academic papers and research more easily, improving their ability to conduct research and write papers.

These are just a few examples of Semantic Search API uses case, it can be applied in any field where there's a need to understand the meaning behind a user's query and provide more accurate and personalized results.

### **Performance variations of Semantic Search APIs**

For all companies who use Semantic Search APIs in their software: cost and performance are real concerns. The Semantic Search market is quite dense and all those providers have their benefits and weaknesses.

Performances of Semantic Search vary according to the specificity of data used by each AI engine for their model training. This means that some Semantic Search may perform great for some languages but won’t necessarily for others.


### **Performance variations according to the languages**

Semantic Search APIs perform differently depending on the language of the text. In fact, some providers are specialized in specific languages. Different specificities exist:

- Region specialties: some Semantic Search APIs improve their machine learning algorithm to make them accurate for text in a specific language spoken in particular countries or regions. For example, some APIs perform well in English (US, UK, Canada, South Africa, Singapore, Hong Kong, Ghana, Ireland, Australia, India, etc.), while others are specialized in Asian languages (Korean, Japanese, Chinese, etc.)
- Rare language specialty: some Semantic Search providers care about rare languages and dialects. You can find Semantic Search APIs that allow you to process text in Gujarati, Marathi, Burmese, Pashto, Zulu, Swahili, etc.


### **Performance variations according to fields**

Some Semantic Search APIs trained their engine with specific data. This means that some Semantic Search APIs will perform better for educational articles, while others will perform better on technical documents.

## **Why choose Eden AI to manage your Semantic Search APIs**

‍Companies and developers from a wide range of industries (Social Media, Retail, Health, Finances, Law, etc.) use Eden AI’s unique API to easily integrate Semantic Search tasks in their cloud-based applications, without having to build their own solutions.

Eden AI offers multiple AI APIs on its platform amongst several technologies: Text-to-Speech, Language Detection, Sentiment Analysis, Question Answering, Data Anonymization, Speech Recognition, Face Detection and so forth.

We want our users to have access to multiple Semantic Search engines and manage them in one place so they can reach high performance, optimize cost and cover all their needs. There are many reasons for using multiple APIs :

‍

- ‍**Fallback provider is the ABCs:** You need to set up a provider API that is requested if and only if the main Semantic Search API does not perform well (or is down). You can use confidence score returned or other methods to check provider accuracy.
- ‍**Performance optimization:** After the testing phase, you will be able to build a mapping of providers’ performance based on the criteria you have chosen (languages, fields, etc.). Each data that you need to process will then be sent to the best Semantic Search API.**‍**
- **Cost - Performance ratio optimization:** You can choose the cheapest Semantic Search provider that performs well for your data.
- ‍**Combine multiple AI APIs:** This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because Semantic Search APIs will validate and invalidate each other for each piece of data.

‍
