What are some of the challenges we face in NLP today? by Muhammad Ishaq DataDrivenInvestor

In the existing literature, most of the work in NLP is conducted by computer scientists while various other professionals have also shown interest such as linguistics, psychologists, and philosophers etc. One of the most interesting aspects of NLP is that it adds up to the knowledge of human language. The field of NLP is related with different theories and techniques that deal with the problem of natural language of communicating with the computers. Some of these tasks have direct real-world applications such as Machine translation, Named entity recognition, Optical character recognition etc. Though NLP tasks are obviously very closely interwoven but they are used frequently, for convenience. Some of the tasks such as automatic summarization, co-reference analysis etc. act as subtasks that are used in solving larger tasks.

Two sentences with totally different contexts in different domains might confuse the machine if forced to rely solely on knowledge graphs. It is therefore critical to enhance the methods used with a probabilistic approach in order to derive context and proper domain choice. Natural Language Processing excels at understanding syntax, but semiotics and pragmatism are still challenging to say the least.

This can make tasks such as speech recognition difficult, as it is not in the form of text data. Homonyms – two or more words that are pronounced the same but have can be problematic for question answering and speech-to-text applications because they aren’t written in text form. Usage of their and there, for example, is even a common problem for humans.

If we create datasets and make them easily available, such as hosting them on openAFRICA, that would incentivize people and lower the barrier to entry. It is often sufficient to make available test data in multiple languages, as this will allow us to evaluate cross-lingual models and track progress. Another data source is the South African Centre for Digital Language Resources (SADiLaR), which provides resources for many of the languages spoken in South Africa. The second topic we explored was generalisation beyond the training data in low-resource scenarios. Given the setting of the Indaba, a natural focus was low-resource languages. The first question focused on whether it is necessary to develop specialised NLP tools for specific languages, or it is enough to work on general NLP.

Or because there has not been enough time to refine and apply theoretical work already done? This volume will be of interest to researchers of computational linguistics in academic and non-academic settings and to graduate students in computational linguistics, artificial intelligence and linguistics. The world’s first smart earpiece Pilot will soon be transcribed over 15 languages. The Pilot earpiece is connected via Bluetooth to the Pilot speech translation app, which uses speech recognition, machine translation and machine learning and speech synthesis technology.

All of the problems above will require more research and new techniques in order to improve on them. It is often possible to perform end-to-end training in deep learning for an application. This is because the model (deep neural network) offers rich representability and information in the data can be effectively ‘encoded’ in the model. For example, in neural machine translation, the model is completely automatically constructed from a parallel corpus and usually no human intervention is needed. This is clearly an advantage compared to the traditional approach of statistical machine translation, in which feature engineering is crucial.

Moreover, a potential source of inaccuracies is related to the quality and diversity of the training data used to develop the NLP model. NLP models are rapidly becoming relevant to higher education, as they have the potential to transform teaching and learning by enabling personalized learning, on-demand support, and other innovative approaches (Odden et al., 2021). In higher education, NLP models have significant relevance for supporting student learning in multiple ways.

  • NLP can be used in chatbots and computer programs that use artificial intelligence to communicate with people through text or voice.
  • The first objective of this paper is to give insights of the various important terminologies of NLP and NLG.
  • Lexical level ambiguity refers to ambiguity of a single word that can have multiple assertions.
  • In case of syntactic level ambiguity, one sentence can be parsed into multiple syntactical forms.
  • Next, you might notice that many of the features are very common words–like “the”, “is”, and “in”.

NLP has paved the way for digital assistants, chatbots, voice search, and a host of applications we’ve yet to imagine. We also have technical challenges that are typical for NLP across industries. Mapping the context, specificity, and personalization of NLP to the industry it serves is challenging.

Higher-level NLP applications

A breaking application should be intelligent enough to separate paragraphs into their appropriate sentence units; however, highly complex data might not always be available in easily recognizable sentence forms. This data may exist in the form of tables, graphics, notations, page breaks, etc., which need to be appropriately processed for the machine to derive meanings in the same way a human would approach interpreting text. Even humans at times find it hard to understand the subtle differences in usage. Therefore, despite NLP being considered one of the more reliable options to train machines in the language-specific domain, words with similar spellings, sounds, and pronunciations can throw the context off rather significantly.
