Clinical Natural Language Processing in languages other than English: opportunities and challenges Journal of Biomedical Semantics Full Text

Synonyms can lead to nlp problems similar to contextual understanding because we use many different words to express the same idea. Furthermore, some of these words may convey exactly the same meaning, while some may be levels of complexity and different people use synonyms to denote slightly different meanings within their personal vocabulary. In summary, there is a sharp difference in the availability of language resources for English on one hand, and other languages on the other hand. Corpus and terminology development are a key area of research for languages other than English as these resources are crucial to make headway in clinical NLP.

Machine-learning models can be predominantly categorized as either generative or discriminative. Generative methods can generate synthetic data because of which they create rich models of probability distributions. Discriminative methods are more functional and have right estimating posterior probabilities and are based on observations. Srihari explains the different generative models as one with a resemblance that is used to spot an unknown speaker’s language and would bid the deep knowledge of numerous languages to perform the match.

The MTM service model and chronic care model are selected as parent theories. Review article abstracts target medication therapy management in chronic disease care that were retrieved from Ovid Medline (2000–2016). Unique concepts in each abstract are extracted using Meta Map and their pair-wise co-occurrence are determined. Then the information is used to construct a network graph of concept co-occurrence that is further analyzed to identify content for the new conceptual model.

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.

Domain-specific language

The naïve bayes is preferred because of its performance despite its simplicity In Text Categorization two types of models have been used . But in first model a document is generated by first choosing a subset of vocabulary and then using the selected words any number of times, at least once irrespective of order. It takes the information of which words are used in a document irrespective of number of words and order. In second model, a document is generated by choosing a set of word occurrences and arranging them in any order. This model is called multi-nomial model, in addition to the Multi-variate Bernoulli model, it also captures information on how many times a word is used in a document.

  • Google translate, were found to have the potential to reduce language bias in the preparation of randomized clinical trials reports language pairs .
  • On the other hand, for more complex tasks that rely on a deeper linguistic analysis of text, adaptation is more difficult.
  • Word sense disambiguation is the selection of the meaning of a word with multiple meanings through a process of semantic analysis that determine the word that makes the most sense in the given context.
  • Generative methods can generate synthetic data because of which they create rich models of probability distributions.
  • Machine Translation is generally translating phrases from one language to another with the help of a statistical engine like Google Translate.
  • However, in some areas obtaining more data will either entail more variability , or is impossible (like getting more resources for low-resource languages).

Jade replied that the most important issue is to solve the low-resource problem. Particularly being able to use translation in education to enable people to access whatever they want to know in their own language is tremendously important. Incentives and skills Another audience member remarked that people are incentivized to work on highly visible benchmarks, such as English-to-German machine translation, but incentives are missing for working on low-resource languages. However, skills are not available in the right demographics to address these problems. What we should focus on is to teach skills like machine translation in order to empower people to solve these problems.

Supporting Natural Language Processing (NLP) in Africa

This is an important challenge to tackle because language is more than a vehicle for communication. This is why we want to make sure you can understand and be understood, in any language of your choosing. It’s a significant technical challenge to make this dream a reality, but we’re committed to and working towards this goal. Altman R. Artificial intelligence systems for interpreting complex medical data sets. A notable use of multilingual corpora is the study of clinical, cultural and linguistic differences across countries.


The technology can then accurately extract information and insights contained in the documents as well as categorize and organize the documents themselves. In summary, we find a steady interest in clinical NLP for a large spectrum of languages other than English that cover Indo-European languages such as French, Swedish or Dutch as well as Sino-Tibetan , Semitic or Altaic languages. We identified the need for shared tasks and datasets enabling the comparison of approaches within- and across- languages. Furthermore, the challenges in systematically identifying relevant literature for a comprehensive survey of this field lead us to also encourage more structured publication guidelines that incorporate information about language and task.

Abstractive Document Summarization with a Graph-Based Attentional Neural Model

Noah Chomsky, one of the first linguists of twelfth century that started syntactic theories, marked a unique position in the field of theoretical linguistics because he revolutionized the area of syntax . Further, Natural Language Generation is the process of producing phrases, sentences and paragraphs that are meaningful from an internal representation. The first objective of this paper is to give insights of the various important terminologies of NLP and NLG.

neural machine translation

Machine translation is the automatic software translation of text from one language to another. For example, English sentences can be automatically translated into German sentences with reasonable accuracy. Conversational agents communicate with users in natural language with text, speech, or both.

Understand your data and the model

The good news is that advancements in NLP do not have to be fully automated and used in isolation. At Loris, we believe the insights from our newest models can be used to help guide the conversation and augment human communication. Understanding how humans and machines can work together to create the best experience will lead to meaningful progress.

While we still have access to the coefficients of our Logistic Regression, they relate to the 300 dimensions of our embeddings rather than the indices of words. It learns from reading massive amounts of text and memorizing which words tend to appear in similar contexts. After being trained on enough data, it generates a 300-dimension vector for each word in a vocabulary, with words of similar meaning being closer to each other. To validate our model and interpret its predictions, it is important to look at which words it is using to make decisions. If our data is biased, our classifier will make accurate predictions in the sample data, but the model would not generalize well in the real world.
