Top 22 Natural Language Processing (NLP) frameworks

More and more businesses rely on the processing of large amounts of natural language data in various formats (images or videos) on the web to develop more value-added services for their customers, depending on their business models.

They use natural language processing (NLP), a subfield of linguistics, data science, data science and artificial intelligence (AI) and machine learning (ML) concerned with the interactions between computers and human languages, to teach machines how to understand human languages and extract meaning.

NLP tools make it simple to handle tasks such as document classification, topic modeling, part-of-speech (POS) tagging, word vectors, and sentiment analysis. NLP is part of our lives for decades. In fact, we interact with NLP daily without even realizing it.

NLP technology is essential for scientific, economic, social, and cultural reasons, including understanding context and emotions from verbal and nonverbal communication that involves a nonlinguistic transmission of information through visual, auditory, tactile, and kinesthetic (physical) channels.

Below is a list of basic functions NLP is used to analyze language for its meaning.

  • Text Classification (e.g. document categorization).
  • Understanding how much time it takes to read a text.
  • Finding words with the same meaning for search.
  • Understanding how difficult it is to read is a text.
  • Generating a summary of a text.
  • Identifying the language of a text.
  • Identifying entities (e.g., cities, people, locations) in a text.
  • Finding similar documents.
  • Text Generation.
  • Translating a text.

This post will present a list of the most important Natural Language Processing (NLP) frameworks you need to know.

Usually, these tasks are required to build more advanced text processing services. OpenNLP also includes maximum entropy and perceptron based machine learning. The goal is to create a mature toolkit for the abovementioned tasks. An additional goal is providing a large number of pre-built models for a variety of languages, as well as the annotated text resources that those models are derived from.

3. Apache Tika

The Apache Tika is a content analysis toolkit used to parse the documents in PDF, Open Document, Excel, and many other well-known binary and text formats using a simple uniform API. It can detect and extract metadata and text from over a thousand different file types.

Gensim is a Python library for topic modeling, document indexing, and similarity retrieval with large corpora. It aims at processing raw, unstructured digital texts. The algorithms in gensim, such as Latent Semantic Analysis, Latent Dirichlet Allocation, or Random Projections, discover the semantic structure of documents, by examining word statistical co-occurrence patterns within a corpus of training documents. These algorithms are unsupervised, which means no human input is necessary – you only need a corpus of plain text documents. Once these statistical patterns are found, any plain text documents can be succinctly expressed in the new, semantic representation, and queried for topical similarity against other documents.
