A Complete Guide to NLP: What it is, How it Works & Use Cases

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. NLP is data-driven, but which kind of data and how much of it is not an easy question to answer. Scarce and unbalanced, as well as too heterogeneous data often reduce the effectiveness of NLP tools. However, in some areas obtaining more data will either entail more variability , or is impossible (like getting more resources for low-resource languages). Besides, even if we have the necessary data, to define a problem or a task properly, you need to build datasets and develop evaluation procedures that are appropriate to measure our progress towards concrete goals.

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. Simultaneously, the user will hear the translated version of the speech on the second earpiece. Moreover, it is not necessary that conversation would be taking place between two people; only the users can join in and discuss as a group. As if now the user may experience a few second lag interpolated the speech and translation, which Waverly Labs pursue to reduce. The Pilot earpiece will be available from September but can be pre-ordered now for $249.

Overcoming Common Challenges in Natural Language Processing

The system incorporates a modular set of foremost multilingual NLP tools. The pipeline integrates modules for basic NLP processing as well as more advanced tasks such as cross-lingual named entity linking, semantic role labeling and time normalization. Thus, the cross-lingual framework allows for the interpretation of events, participants, locations, and time, as well as the relations between them. Output of these individual pipelines is intended to be used as input for a system that obtains event centric knowledge graphs.


Another example is named entity recognition, which extracts the names of people, places and other entities from text. Artificial intelligence and machine learning methods make it possible to automate content generation. Some companies specialize in automated content creation for Facebook and Twitter ads and use natural language processing to create text-based advertisements.

What are the top 5 use cases of NLP?

It is used when there’s more than one possible name for an event, person, place, etc. The goal is to guess which particular object was mentioned to correctly identify it so that other tasks like relation extraction can use this information. Natural language refers to the way we, humans, communicate with each other. Speakers and writers use various linguistic features, such as words, lexical meanings, syntax , semantics , etc., to communicate their messages.

Section 3 deals with the history of NLP, applications of NLP and a walkthrough of the recent developments. Datasets used in NLP and various approaches are presented in Section 4, and Section 5 is written on evaluation metrics and challenges involved in NLP. Earlier machine learning techniques Problems in NLP such as Naïve Bayes, HMM etc. were majorly used for NLP but by the end of 2010, neural networks transformed and enhanced NLP tasks by learning multilevel features. Major use of neural networks in NLP is observed for word embedding where words are represented in the form of vectors.

The main challenge of NLP is the understanding and modeling of elements within a variable context. In a natural language, words are unique but can have different meanings depending on the context resulting in ambiguity on the lexical, syntactic, and semantic levels. To solve this problem, NLP offers several methods, such as evaluating the context or introducing POS tagging, however, understanding the semantic meaning of the words in a phrase remains an open task. Another big open problem is dealing with large or multiple documents, as current models are mostly based on recurrent neural networks, which cannot represent longer contexts well. Working with large contexts is closely related to NLU and requires scaling up current systems until they can read entire books and movie scripts. However, there are projects such as OpenAI Five that show that acquiring sufficient amounts of data might be the way out.

Why is NLP a hard problem?

Why is NLP difficult? Natural Language processing is considered a difficult problem in computer science. It's the nature of the human language that makes NLP difficult. The rules that dictate the passing of information using natural languages are not easy for computers to understand.

The semantic layer that will understand the relationship between data elements and its values and surroundings have to be machine-trained too to suggest a modular output in a given format. 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.

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. Stephan suggested that incentives exist in the form of unsolved problems. 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. Academic progress unfortunately doesn’t necessarily relate to low-resource languages. However, if cross-lingual benchmarks become more pervasive, then this should also lead to more progress on low-resource languages.

The NLP philosophy that we can ‘model’ what works from others is a great idea. But when you simply learn the technique without the strategic conceptualisation; the value in the overall treatment schema; or the potential for harm – then you are being given a hammer to which all problems are just nails. ‘Programming’ is something that you ‘do’ to a computer to change its outputs. The idea that an external person can ‘program’ away problems, insert behaviours or outcomes removes all humanity and agency from the people being ‘programmed’.
