Challenges in Developing Multilingual Language Models in Natural Language Processing NLP by Paul Barba


Natural Language Processing NLP and Computer Vision

The technology can then accurately extract information and insights contained in the documents as well as categorize and organize the documents themselves. There are a number of additional resources that are relevant to this class of applications. CrisisBench is a benchmark dataset including social media text labeled along dimensions relevant for humanitarian action (Alam et al., 2021). This dataset contains collections of tweets from multiple major natural disasters, labeled by relevance, intent (offering vs. requesting aid), and sector of interest. Lacuna Fund13 is an initiative that aims at increasing availability of unbiased labeled datasets from low- or middle-income contexts. Over the past few years, NLP has witnessed tremendous progress, with the advent of deep learning models for text and audio (LeCun et al., 2015; Ruder, 2018b; Young et al., 2018) inducing a veritable paradigm shift in the field4.

Therefore, you need to ensure that your models can handle the nuances and subtleties of language, that they can adapt to different domains and scenarios, and that they can capture the meaning and sentiment behind the words. In the example above “enjoy working in a bank” suggests “work, or job, or profession”, while “enjoy near a river bank” is just any type of work or activity that can be performed near a river bank. 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. Ambiguity is the main challenge of natural language processing because in natural language, words are unique, but they have different meanings depending upon the context which causes ambiguity on lexical, syntactic, and semantic levels. Natural language processing is the capability of a ‘smart’ computer system to understand human language – as it is both written and spoken.

Data Augmentation using Transformers and Similarity Measures.

Planning, funding, and response mechanisms coordinated by United Nations’ humanitarian agencies are organized in sectors and clusters. Clusters are groups of humanitarian organizations and agencies that cooperate to address humanitarian needs of a given type. Sectors define the types of needs that humanitarian organizations typically address, which include, for example, food security, protection, health.

Natural Language Processing, or NLP, is a field derived from artificial intelligence, computer science, and computational linguistics that focuses on the interactions between human (natural) languages and computers. The main goal of NLP is to program computers to successfully process and analyze linguistic data, whether written or spoken. Natural language processing has existed for well over fifty years, and the technology has its origins in linguistics or the study It has an assortment of real-world applications within a number of industries and fields, including intelligent search engines, advanced medical research, and business processing intelligence. We hope our walkthrough of these tasks helped you build some [newline]intuition on just how machines are able to unpack and process natural [newline]language, demystifying some of the space.

Generative Learning

An NLP processing model needed for healthcare, for example, would be very different than one used to process legal documents. These days, however, there are a number of analysis tools trained for specific fields, but extremely niche industries may need to build or train their own models. So, for building NLP systems, it’s important to include all of a word’s possible meanings and all possible synonyms. Text analysis models may still occasionally make mistakes, but the more relevant training data they receive, the better they will be able to understand synonyms. This is where contextual embedding comes into play and is used to learn sequence-level semantics by taking into consideration the sequence of all words in the documents.


Some of them (such as irony or sarcasm) may convey a meaning that is opposite to the literal one. Even though sentiment analysis has seen big progress in recent years, the correct understanding of the pragmatics of the text remains an open task. The second problem is that with large-scale or multiple documents, supervision is scarce and expensive to obtain. We can, of course, imagine a document-level unsupervised task that requires predicting the next paragraph or deciding which chapter comes next. A more useful direction seems to be multi-document summarization and multi-document question answering. CapitalOne claims that Eno is First natural language SMS chatbot from a U.S. bank that allows customers to ask questions using natural language.

Xie et al. [154] proposed a neural architecture where candidate answers and their representation learning are constituent centric, guided by a parse tree. Under this architecture, the search space of candidate answers is reduced while preserving the hierarchical, syntactic, and compositional structure among constituents. Sentiment analysis is another way companies could use NLP in their operations. The software would analyze social media posts about a business or product to determine whether people think positively or negatively about it. Spelling mistakes and typos are a natural part of interacting with a customer. Our conversational AI platform uses machine learning and spell correction to easily interpret misspelled messages from customers, even if their language is remarkably sub-par.
