Natural Language Processing Expert

Natural Language Processing Expert Explains:

If your company has a large number of unstructured documents such as CVs, inspection reports, health records, or otherwise, and you are struggling to extract value from them, you could be sitting on a gold mine of data and it might be time to call in a Natural Language Processing expert. Or maybe your organisation needs to build a chatbot, or analyse and triage emails? In any case our company of NLP experts Fast Data Science can help.

What is Natural Language Processing (NLP)? NLP is a discipline within artificial intelligence dealing with analysis of human language. With NLP we can interpret documents written by humans, for humans. NLP also includes natural language dialogue systems such as Siri on the iPhone, as well as speech recognition and speech synthesis systems, and search engines! So you might be using NLP systems every day without realising.

Natural language processing has its roots in the 1950s. Already in 1950, Alan Turing published an article titled “Computing Machinery and Intelligence” which proposed what is now called the Turing test as a criterion of intelligence/, a task that involves the automated interpretation and generation of natural language (e.g. “We are searching in the database”), but at the time not articulated as a problem separate from artificial intelligence.

Natural Language Processing Experts Fast Data Science

At Fast Data Science we take pride in our natural language processing expertise (NLP). We offer expert consulting in many areas of data science and our main area of focus is NLP. The manager, Thomas Wood, studied a Masters in 2008 at Cambridge University in Computer Speech, Text and Internet Technology and since then he has been working exclusively in machine learning and mostly in NLP. In 2018 he founded Fast Data Science to deliver data science expertise, focusing on NLP. You can read the bios of Thomas Wood and the other Natural Language Processing Experts in our team on the team page. In addition to building NLP pipelines from scratch, our team has worked on natural language dialogue systems, document classifiers and text based recommender systems. For these tasks, we have used both traditional machine learning techniques as well as the state of the art such as deep learning, convolutional neural networks, BERT, and the like. You can read a post about transformers (the current cutting-edge NLP model) by Thomas Wood on here. Our NLP experts normally use Python but we can adapt to your organisation’s preferred technology stack.

Experts in NLP and unstructured data

Today many companies, in particular in certain industries such as healthcare, pharmaceuticals, legal, and insurance, have large amounts of unstructured data. This is typically data in text format, which may even be unscanned documents, PDFs, HTML, or any other file type.

Unstructured data is very difficult to deal with but can contain a goldmine of information. Fast Data Science specialises in extracting value from organisations’ unstructured datasets.

Natural Language Processing applications in healthcare

Natural Language Processing applications in healthcare Natural Language Processing applications in healthcare

AI and natural language processing are being increasingly adopted across the healthcare sector.

This technology is sometimes called healthtech or MedTech. NLP is being used to compare and detect changes in clinical reports, extract clinical concepts such as MeSH terms from electronic medical records, and develop human-to-machine natural language dialogue systems to improve the healthcare experience.

We have worked on a number of projects in healthcare, including:

Natural Language Processing technologies at Fast Data Science

As NLP experts, we do a lot of natural language processing with Python. We have worked on a variety of NLP models, including:

  • Bag of words, tf*idf, cosine similarity
  • NLP pipelines, lemmatisation, parsers, chunkers
  • Deep neural networks
  • Clustering: Latent Dirichlet Allocation
    • This is useful for extracting topics from a set of unstructured documents, for example legal documents, survey responses, factory error reports, etc.
  • Search engines and search term recommenders
  • Google Natural Language, AWS, Microsoft Azure

Topic detection is an NLP technique that allows you to discover common themes in a set of unstructured documents. Topic detection is an NLP technique that allows you to discover common themes in a set of unstructured documents.

Natural Language Processing in Python and R

We work with the following programming languages and frameworks:

  • TensorFlow
  • Keras
  • Python NLTK
  • R

Examples of past Natural Language Processing projects

NLP projects we have worked on for major household names include

  • a spoken dialogue system to control a smart home
  • an unsupervised text analysis program to analyse text descriptions of manufacturing defects (Boehringer Ingelheim)
  • a model to classify jobseekers’ CVs into industries and salary bands (CV-Library).
  • analysis of survey responses (White Ribbon Alliance)
