Top Free Topic/Entity Extraction tools, APIs, and Open Source models

What is Topic Extraction API?

Topic Extraction API, also called Entity Extraction or Content Taxonomy, uses natural language processing to identify the main ideas and concepts in a text and group them into meaningful topics.It then returns a list of topics with their associated keywords or phrases.

This technology can analyze different types of text data, such as articles, social media posts, customer reviews and others. The Topic Extraction API has many uses, including organizing content, gauging emotions, identifying trends, and optimizing search engines.

It's important to highlight that the Topic Extraction API is immediately available for use, as opposed to Custom Text Classification, which necessitates a dataset prior to implementation.

Top Open Source (Free) Entity Extraction models on the market

For users seeking a cost-effective engine, opting for an open-source model is the recommended choice. Here is the list of the best Entity Extraction Open Source Models:

‍

1‍. Genism

Gensim is a prevalent open-source tool in Python for topic modeling. It implements various efficient algorithms for modeling topics, like Latent Dirichlet Allocation (LDA) and Latent Semantic Analysis (LSA). Further, it features a user-friendly interface that simplifies training and using topic models.

‍

2. scikit-learn

Scikit-learn is a Python library for machine learning that provides different topic modelling methods, including Latent Dirichlet Allocation (LDA), Non-Negative Matrix Factorisation (NMF), and Latent Semantic Analysis (LSA).

‍

3. BERTopic

BERTopic is a method for extracting topics that uses BERT embeddings to enhance the process. It is constructed on the Hugging Face Transformers library.

‍

4. Top2Vec

Top2Vec is an algorithm that combines topic modeling and document embeddings. It's designed to discover topics in large document collections.

‍

5. Mallet

MALLET is a Java program that assists in processing language for things such as topic modeling. You can use it for different text tasks because it can implement a variety of machine learning algorithms, including Latent Dirichlet Allocation (LDA), which is useful for topic modeling.

‍

6. tomotopy

Tomotopy is a topic modeling library for Python that supports various algorithms, including Latent Dirichlet Allocation (LDA), Hierarchical Dirichlet Process (HDP), and more. It provides an easy-to-use interface for topic modeling tasks.

‍

7. BTM

BTM is a technique for discovering topics in short texts. It models biterms, which are when two words appear together in a short context. This method is especially helpful for short documents.

Cons of Using Open Source AI models

‍While open source models offer many advantages, they also have potential drawbacks and challenges. Here are some cons of using open source models:

‍

• Not Entirely Cost Free: Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear hosting and server usage expenses, especially when dealing with large or resource-intensive data sets.
• Lack of Support: Open source models may not have official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
• Limited Documentation: Some open source models may have incomplete or poorly maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
• Security Concerns: Security vulnerabilities can exist in open source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open source models may need to monitor for security updates and patches actively.
• Scalability and Performance: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle a large number of requests, you may need to invest more time in optimization.
