Bias in Natural Language Processing NLP: A Dangerous But Fixable Problem by Jerry Wei

natural language processing problems

If you have any Natural Language Processing questions for us or want to discover how NLP is supported in our products please get in touch. So how does this affect companies, especially those that rely heavily on chatbots? While Natural Language Processing (NLP) certainly can’t work miracles and ensure a chatbot appropriately responds to every message, it is powerful enough to make-or-break a chatbot’s success. Don’t underestimate this critical and often overlooked aspect of chatbots.

As they grow and strengthen, we may have solutions to some of these challenges in the near future. There definitely seems to be more positive articles across the news categories here as compared to our previous model. However, still looks like technology has the most negative articles and world, the most positive articles similar to our previous analysis. Let’s now do a comparative analysis and see if we still get similar articles in the most positive and negative categories for world news.

The COPD Foundation uses text analytics and sentiment analysis, NLP techniques, to turn unstructured data into valuable insights. These findings help provide health resources and emotional support for patients and caregivers. Learn more about how analytics is improving the quality of life for those living with pulmonary disease. To be sufficiently trained, an AI must typically review millions of data points. Processing all those data can take lifetimes if you’re using an insufficiently powered PC.

Finally, we can even evaluate and compare between these two models as to how many predictions are matching and how many are not (by leveraging a confusion matrix which is often used in classification). We can see that people, places and organizations are the most mentioned entities though interestingly we also have many other entities. You can notice the similarities with the tree we had obtained earlier. The annotations help with understanding the type of dependency among the different tokens. You can also leverage nltk and the StanfordDependencyParser to visualize and build out the dependency tree. We showcase the dependency tree both in its raw and annotated form as follows.

Natural Language Processing (NLP): 7 Key Techniques

Examples of these issues include spelling and grammatical errors and poor language use in general. Advanced Natural Language Processing (NLP) capabilities can identify spelling and grammatical errors and allow the chatbot to interpret your intended message despite the mistakes. If you have any feedback, comments or interesting insights to share about my article or data science in general, feel free to reach out to me on my LinkedIn social media channel. Looks like the most negative article is all about a recent smartphone scam in India and the most positive article is about a contest to get married in a self-driving shuttle.

OpenAI’s GPT-3 — a language model that can automatically write text — received a ton of hype this past year. Beijing Academy of AI’s WuDao 2.0 (a multi-modal AI system) and Google’s Switch Transformers are both considered more powerful models that consist of over 1.6 trillion parameters dwarfing GPT-3’s measly 175 billion parameters. Well, looks like the most negative world news article here is even more depressing than what we saw the last time! The most positive article is still the same as what we had obtained in our last model. We can see that the spread of sentiment polarity is much higher in sports and world as compared to technology where a lot of the articles seem to be having a negative polarity. Stanford’s Named Entity Recognizer is based on an implementation of linear chain Conditional Random Field (CRF) sequence models.

It also includes libraries for implementing capabilities such as semantic reasoning, the ability to reach logical conclusions based on facts extracted from text. So let’s say our data tends to put female pronouns around the word “nurse” and male pronouns around the word “doctor.” Our model will learn those patterns from and learn that nurse is usually female and doctor is usually male. By no fault of our own, we’ve accidentally trained our model to think doctors are male and nurses are female. Another big open problem is reasoning about large or multiple documents. The recent NarrativeQA dataset is a good example of a benchmark for this setting.

Join us as we explore the benefits and challenges that come with AI implementation and guide business leaders in creating AI-based companies. Wojciech enjoys working with small teams where the quality of the code and the project’s direction are essential. In the long run, this allows him to have a broad understanding of the subject, develop personally and look for challenges. Additionally, Wojciech is interested in Big Data tools, making him a perfect candidate for various Data-Intensive Application implementations.

However, despite best efforts, it is nearly impossible to collect perfectly clean data, especially at the scale demanded by deep learning. Neural machine translation, based on then-newly-invented sequence-to-sequence transformations, made obsolete the intermediate steps, such as word alignment, previously necessary for statistical machine translation. NLP sophisticated, yet much work remains to be done. Current systems are prone to bias and incoherence, and occasionally behave erratically. Despite the challenges, machine learning engineers have many opportunities to apply NLP in ways that are ever more central to a functioning society.

  • Furthermore, each POS tag like the noun (N) can be further subdivided into categories like singular nouns (NN), singular proper nouns (NNP), and plural nouns (NNS).
  • Academic progress unfortunately doesn’t necessarily relate to low-resource languages.
  • Let’s dive deeper into the most positive and negative sentiment news articles for technology news.
  • This is where the

    statistical NLP methods are entering and moving towards more complex and powerful NLP solutions based on deep learning


  • For example, NLP makes it possible for computers to read text, hear speech, interpret it, measure sentiment and determine which parts are important.

Models that can predict the next word in a sequence can then be fine-tuned by machine learning practitioners to perform an array of other tasks. Topic models can be constructed using statistical methods or other machine learning techniques like deep neural

networks. The complexity of these models varies depending on what type you choose and how much information there is

available about it (i.e., co-occurring words).

Planning for NLP

So can you take a plan of a building  and ask questions like…Can you come up with a detailed work schedule from the BIM? Or if you  have the schedule listing different steps, can you  verify that this is the right order? If you think  about the final [textual] products, it’s hard linking what’s actually happening on the construction site. SAS analytics solutions transform data into intelligence, inspiring customers around the world to make bold new discoveries that drive progress. This is where training and regularly updating custom models can be helpful, although it oftentimes requires quite a lot of data. With spoken language, mispronunciations, different accents, stutters, etc., can be difficult for a machine to understand.

Sentences are broken on punctuation marks, commas in lists, conjunctions like “and”

or “or” etc. It also needs to consider other sentence specifics, like that not every period ends a sentence (e.g., like

the period in “Dr.”). Natural Language Processing is usually divided into two separate fields – natural language understanding (NLU) and

natural language generation (NLG).
