Nowadays a lot of information are in the text format (books, documents, articles, social media posts, messages, reviews, chat’s conversation, description, website info etc.). Those files contains a lot of valuable information that can support business activities. Insights from text data could be extracted using NLP applications. NLP applications in enterprises range from document management support to customer support via chatbots or dialog bots by creating automated answers to the most common questions.

Since artificial intelligence (AI) allow modeling of nonlinear cases, it have turned into a very popular and useful tool for solving many different problems such as pattern recognition, machine translation, anomaly detection, decision making, computer vision and many other. It allows to use artificial intelligence algorithms such as neural networks in many areas. Below, in this article we will describe applications of AI-based NLP solutions.

NLP application

Natural Language Processing (NLP) applications

Natural Language Processing is a suit of techniques and algorithms that give computers the ability to read, understand and derive meaning from the human languages. The challenge with NLP is that computers are built to understand programming languages, which are explicit and highly structured, while natural language is anything but explicit and it’s structure is often not so rigid. Due to those factors, it has always been difficult for machines to grasp the context of natural language. Moreover, creating elaborate sets of rules that was started in 1950s could only work for narrow problems and with limited success. But with the help of data science consulting company, computers can now cope with the uncertainty of human language.

Some of the most common NLP applications

Sentiment analysis

NLP types

Currently most of the companies monitor their online presence using NLP applications. Consumers talk about brands on social media platforms, voicing both their positive and negative opinions about them. This is a great opportunity for companies, but also a great threat. Not acting fast enough to ever changing public opinion may have huge impact on company bottom line. Sheer amount of posts published everyday on social media platforms makes it impossible for company employees to monitor and react to everything.

Luckily NLP applications helps with such problems with algorithms tailored for sentiment analysis. They can analyze in seconds multitude of posts and classify their polarity as positive, negative or neutral. Such speed enables near real-time analysis of social media. Common example of NLP application is analyzing streams of tweets to detect shifts in the public perception of given brand.

loyalty and marketing

It is worth noting that there is no silver bullet for sentiment analysis, there is no universal sentiment detector. Creation of a detector is a tailored process which requires annotated datasets on which algorithms can learn what is considered positive or negative in given business. Sentiment analysis is commonly used in customer service and marketing.

Text Classification and Categorization (on of the most popular NLP applications)

Text Classification and Categorization could be used in many NLP applications. Examples of those applications are web searching (search engines), language identification, information filtering and readability assessment.

Text categorization and classification can bring automatization and simplification to your applications and companies operations. Classifying large textual data also helps in standardizing the platform, make search easier and relevant, and improves user experience by simplifying navigation.

Text summarisation

Length of many documents and articles is an obstacle in finding relevant information fast and efficiently. Often documents don’t indicate clearly what can be found in them, there is no summary written. But NLP application can help with such problems and automatically generate such summaries. There are two approaches to this task. First – extraction, works with the use of algorithms such as TextRank (related to Google’s PageRank), to find and extract the most important sentences or even paragraphs that capture the essence of the document. Second – abstraction, works a bit different and after finding the essence of a given document, it tries to write a summary and not merely return most important parts of original text.

This approach is most similar to what human would do, but it is also a lot more trickier to implement. It is currently still under active research. In most cases extraction-based approach is used in current systems. Additionally, text summarisation algorithms are often coupled with search engines so that apart from the full result also a short summary can be seen.

Text summarisation

Extraction-based approach doesn’t require training data, but it is a good idea to have some example documents to test and tweak algorithm parameters for the most desirable output. In case of abstraction-based approach training data is required, full documents paired with their summaries – the more the better, so that the algorithm can have enough examples to learn from.

Text summarisation is commonly used in law, medical and HR companies.

Named Entity Recognition

Internet is a rich source of data, mainly textual data. But making use of huge quantities of data is a time consuming tasks. NLP can help with this problem through the use of Named Entity Recognition systems. Named entities are terms that refer to names, organisations, locations, values etc. NER annotates texts – marking where and what type of named entities occurred in it. This step significantly simplifies further use of such data, allowing for easy categorisation of documents based on what entities are present in them, for example into texts about competitors, new legislation or company’s own brands.

Named Entity Recognition is of great help for other NLP tasks, making it easier to analyze sentiment only of the opinions concerning given company and not all opinions online or improving automatically generated summaries. On its own NER can be helpful in analyzing popularity of brands, making it easy to monitor the frequency of their mentions online.

NLP application

There are available tools for Named Entity Recognition which work great for general use cases, but when some more niche entities are of interest, it is necessary to collect and annotate data and train the model for specific cases.

Named Entity Recognition is commonly used in brand monitoring, journalism and finances.

Optical character recognition

Not all information online is presented in textual form. There is multitude of infographics, invitations, posters, document scans etc, that are pictures with the text embedded in them. This fact makes information retrieval and analysis problematic. Fortunately also here NLP application can help, for such cases optical character recognition (OCR) algorithms are used. Such algorithms are trained to detect and recognize shapes of letters and numbers and return them in the form of text that can be further analyzed using other text processing techniques.

Of course such algorithms are not perfect, pretrained models are able to detect letters that are clearly visible and in common fonts. For cases with noisy pictures or fancy fonts training a model may be a better solution, even though a huge training set is required, but even then model will not be error-prone.

Optical character recognition is most often used for digitalization of printed documents.

Machine Translation

Machine translation

Today, AI technology has big potential and automates work in various industries and actions. Machine Translation can be called also as a private machine translation engine. That is, the case where translator (human) has his/her own machine translation engine at his/her disposal for translations. Adaptive machine learning translation engine is self-learning. This kind of algorithm adapts and even learns in real time as segments are translated using the software.

All changes are therefore made instantly in the text which makes the text more coherent and adapted to customised analysis. Data is the key to this system, as it drives the analysis. To sum up, if the subject matter to be analysed increases, translations will approximate human translations in terms of quality and fluidity.

Chatbots

Chatbots and virtual assistants are used to automatically answer questions, they are designed to understand natural language and give an appropriate answer by generating natural language. These intelligent machines are becoming more common on the front lines of customer service because they can help teams in answering 80% of basic questions and directing more complicated problems to human agents. Furthermore, such NLP applications are gaining popularity every year. [1]

Market Intelligence

Marketers use natural language applications in real life to learn more about their customers and use these information to build more successful strategies. Analyzing topics, emotions, keyphrases in unstructured data can significantly improve marketing research by opening up new trends and business opportunities. [1] NLP applications are expected to play a more influential role in the functioning of business organizations in 2021. The business will depend heavily on natural language programming when planning future steps. Other applications, such as reputation management, neural machine translation, talent acquisition, data visualization, and even process automation, will have the core components of NLP.

NLP applications in the real life used by companies

NLP based on epidemiological study

During the coronavirus outbreak in China, Alibaba’s Damo Academy developed the StructBERT NLP model. This model, implemented in the Alibaba ecosystem, used not only the search engine on Alibaba’s retail platforms, but also the analysis of anonymous medical data. Natural Language Processing application StructBERT has been also actively used to fight the coronavirus in many Chinese cities. [2]

NLP based competitive analysis

There are many tools available to assist entrepreneurs in tracking down their competitors. Such an example is Zirra, an NLP-based engine that simplifies the process of automatically creating a competitive environment. The Zirra NLP application makes a list of companies and ranks them from zero to one. This list and rating are created by Zirra by scanning the Internet for articles and placing data in the natural language programming module. [2]

NLP application tool – SignAll

SignAll has developed a technology that is able to recognize and translate sign language. It can be used in both business and education. Using advanced natural language processing and machine translation techniques, visual input is transformed into meaningful data for efficient sign language detection and translation. [3] In fact, this NLP application tool can help individuals who are deaf communicate with those who don’t know sign language.

NLP solution for optimization of contract processes

Natural language processing applications use the Python programming language to help businesses process contracts quickly. COIN (short for Contract Intelligence) is a text mining program created by JPMorgan Chase that can read and analyze commercial credit contracts. COIN can do document analysis by highlighting and extracting specific words or phrases. According to reports, this NLP application saves the company 360,000 hours each year. [4]

NLP implementation in personal assistant

Digital personal assistants, such as Alexa, have grown in popularity in recent years. The success of these bots largely depends on the use of natural language programming and generation tools. Alexa can perform more than 70,000 skills. NLP and machine learning have played a key role in this rapid evolution. Currently, there are over 28,000 smart home devices that can be connected with Alexa. You can watch a short video about Alexa:
