Unraveling the Power of Semantic Analysis: Uncovering Deeper Meaning and Insights in Natural Language Processing NLP with Python by TANIMU ABDULLAHI
Whether it is analyzing customer reviews, social media posts, or any other form of text data, sentiment analysis can provide valuable information for decision-making and understanding public sentiment. With the availability of NLP libraries and tools, performing sentiment analysis has become more accessible and efficient. As we have seen in this article, Python provides powerful libraries and techniques that enable us to perform sentiment analysis effectively. By leveraging these tools, we can extract valuable insights from text data and make data-driven decisions. This involves training the model to understand the world beyond the text it is trained on, enabling it to generate more accurate and contextually relevant responses.
However, as our goal was to develop a general mapping of a broad field, our study differs from the procedure suggested by Kitchenham and Charters [3] in two ways. Firstly, Kitchenham and Charters [3] state that the systematic review should be performed by two or more researchers. Homonymy and polysemy deal with the closeness or relatedness of the senses between words.
As we discussed, the most important task of semantic analysis is to find the proper meaning of the sentence. For example, analyze the sentence “Ram is great.” In this sentence, the speaker is talking either about Lord Ram or about a person whose name is Ram. That is why the job, to get the proper meaning of the sentence, of semantic analyzer is important.
Now, we have a brief idea of meaning representation that shows how to put together the building blocks of semantic systems. In other words, it shows how to put together entities, concepts, relations, and predicates to describe a situation. Usually, relationships involve two or more entities such as names of people, places, company names, etc. Understanding these terms is crucial to NLP programs that seek to draw insight from textual information, extract information and provide data. It is also essential for automated processing and question-answer systems like chatbots. Moreover, QuestionPro might connect with other specialized semantic analysis tools or NLP platforms, depending on its integrations or APIs.
This integration of world knowledge can be achieved through the use of knowledge graphs, which provide structured information about the world. One approach to address this challenge is through the use of word embeddings that capture the different meanings of a word based on its context. Another approach is through the use of attention mechanisms in the neural network, which allow the model to focus on the relevant parts of the input when generating a response. You see, the word on its own matters less, and the words surrounding it matter more for the interpretation. A semantic analysis algorithm needs to be trained with a larger corpus of data to perform better. Natural Language Processing or NLP is a branch of computer science that deals with analyzing spoken and written language.

The authors argue that search engines must also be able to find results that are indirectly related to the user’s keywords, considering the semantics and relationships between possible search results. Whether using machine learning Chat PG or statistical techniques, the text mining approaches are usually language independent. Besides, linguistic resources as semantic networks or lexical databases, which are language-specific, can be used to enrich textual data.
I will explore a variety of commonly used techniques in semantic analysis and demonstrate their implementation in Python. By covering these techniques, you will gain a comprehensive understanding of how semantic analysis is conducted and learn how to apply these methods effectively using the Python programming language. Expert.ai’s rule-based technology starts by reading all of the words within a piece of content to capture its real meaning.
As LLMs continue to improve, they are expected to become more proficient at understanding the semantics of human language, enabling them to generate more accurate and human-like responses. For instance, the phrase “I am feeling blue” could be interpreted literally or metaphorically, depending on the context. In semantic analysis, machines are trained to understand and interpret such contextual nuances. Some competitive advantages that business can gain from the analysis of social media texts are presented in [47–49].
Example # 2: Hummingbird, Google’s semantic algorithm
IBM’s Watson provides a conversation service that uses semantic analysis (natural language understanding) and deep learning to derive meaning from unstructured data. It analyzes text to reveal the type of sentiment, emotion, data category, and the relation between words based on the semantic role of the keywords used in the text. According to IBM, semantic analysis has saved 50% of the company’s time on the information gathering process.
The majority of the semantic analysis stages presented apply to the process of data understanding. Semantic analysis, in the broadest sense, is the process of interpreting the meaning of text. It involves understanding the context, the relationships between words, and the overall message that the text is trying to convey. In natural language processing (NLP), semantic analysis is used to understand the meaning of human language, enabling machines to interact with humans in a more natural and intuitive way. Machine learning-based semantic analysis involves sub-tasks such as relationship extraction and word sense disambiguation. It’s an essential sub-task of Natural Language Processing and the driving force behind machine learning tools like chatbots, search engines, and text analysis.
With the help of meaning representation, unambiguous, canonical forms can be represented at the lexical level. The main difference between them is that in polysemy, the meanings of the words are related but in homonymy, the meanings of the words are not related. For example, if we talk about the same word “Bank”, we can write the meaning ‘a financial institution’ or ‘a river bank’. In that case it would be the example of homonym because the meanings are unrelated to each other.
All factors considered, Uber uses semantic analysis to analyze and address customer support tickets submitted by riders on the Uber platform. In simple words, we can say that lexical semantics represents the relationship between lexical items, the meaning of sentences, and the syntax of the sentence. But before deep dive into the concept and approaches related to meaning representation, firstly we have to understand the building blocks of the semantic system. That means the sense of the word depends on the neighboring words of that particular word.
By disambiguating words and assigning the most appropriate sense, we can enhance the accuracy and clarity of language processing tasks. WSD plays a vital role in various applications, including machine translation, information retrieval, question answering, and sentiment analysis. Semantic analysis, also known as semantic parsing or computational semantics, is the process of extracting meaning from language by analyzing the relationships between words, phrases, and sentences. Semantic analysis aims to uncover the deeper meaning and intent behind the words used in communication. Semantic Analysis is a subfield of Natural Language Processing (NLP) that attempts to understand the meaning of Natural Language.
Tasks Involved in Semantic Analysis
Text summarization extracts words, phrases, and sentences to form a text summary that can be more easily consumed. The accuracy of the summary depends on a machine’s ability to understand language data. In the ever-expanding era of textual information, it is important for organizations to draw insights from such data to fuel businesses. Semantic Analysis helps machines interpret the meaning of texts and extract useful information, thus providing invaluable data while reducing manual efforts.
In the second part, the individual words will be combined to provide meaning in sentences. The purpose of semantic analysis is to draw exact meaning, or you can say dictionary meaning from the text. The automated process of identifying in which sense is a word used according to its context. Besides, Semantics Analysis is also widely employed to facilitate the processes of automated answering systems such as chatbots – that answer user queries without any human interventions. Uber strategically analyzes user sentiments by closely monitoring social networks when rolling out new app versions. This practice, known as “social listening,” involves gauging user satisfaction or dissatisfaction through social media channels.
These models are trained on vast amounts of text data, enabling them to learn the nuances and complexities of human language. Semantic analysis plays a crucial role in this learning process, as it allows the model to understand the meaning of the text it is trained on. The next level is the syntactic level, that includes representations based on word co-location or part-of-speech tags. The most complete representation level is the semantic level and includes the representations based on word relationships, as the ontologies.
The more they’re fed with data, the smarter and more accurate they become in sentiment extraction. Can you imagine analyzing each of them and judging whether it has negative or positive sentiment? One of the most useful NLP tasks is sentiment analysis – a method for the automatic detection of emotions behind the text. But before getting into the concept and approaches related to meaning representation, we need to understand the building blocks of semantic system. The goal of NER is to extract and label these named entities to better understand the structure and meaning of the text.
Another area of research is the improvement of common sense reasoning in LLMs, which is crucial for the model to understand and interpret the nuances of human language. Moreover, semantic categories such as, ‘is the chairman of,’ ‘main branch located a’’, ‘stays at,’ and others connect the above entities. However, machines first need to be trained to make sense of human language and understand the context in which words are used; otherwise, they might misinterpret the word “joke” as positive. In the social sciences, textual analysis is often applied to texts such as interview transcripts and surveys, as well as to various types of media.
Other approaches include analysis of verbs in order to identify relations on textual data [134–138]. However, the proposed solutions are normally developed for a specific domain or are language dependent. Relationship extraction involves first identifying various entities present in the sentence and then extracting the relationships between those entities.
Semantic analysis is defined as a process of understanding natural language (text) by extracting insightful information such as context, emotions, and sentiments from unstructured data. This article explains the fundamentals of semantic analysis, how it works, examples, and the top five semantic analysis applications in 2022. In AI and machine learning, semantic analysis helps in feature extraction, sentiment analysis, and understanding relationships in data, which enhances the performance of models.
Semantic Analysis
Semantic analysis tech is highly beneficial for the customer service department of any company. Moreover, it is also helpful to customers as the technology enhances the overall customer experience at different levels. It’s an essential sub-task of Natural Language Processing (NLP) and the driving force behind machine learning tools like chatbots, search engines, and text analysis. This module covers the basics of the language, before looking at key areas such as document structure, links, lists, images, forms, and more. Large Language Models (LLMs) like ChatGPT leverage semantic analysis to understand and generate human-like text.
QuestionPro often includes text analytics features that perform sentiment analysis on open-ended survey responses. While not a full-fledged semantic analysis tool, it can help understand the general sentiment (positive, negative, neutral) expressed within the text. Search engines can provide more relevant results by understanding user queries better, considering the context and meaning rather than just keywords. For instance, understanding that Paris is the capital of France, or that the Earth revolves around the Sun. One approach to improve common sense reasoning in LLMs is through the use of knowledge graphs, which provide structured information about the world. Another approach is through the use of reinforcement learning, which allows the model to learn from its mistakes and improve its performance over time.
By allowing customers to “talk freely”, without binding up to a format – a firm can gather significant volumes of quality data. The most popular example is the WordNet [63], an electronic lexical database developed at the Princeton University. Depending on its usage, WordNet can also be seen as a thesaurus or a dictionary [64]. Jovanovic et al. [22] discuss the task of semantic tagging in their paper directed at IT practitioners. Polysemy refers to a relationship between the meanings of words or phrases, although slightly different, and shares a common core meaning under elements of semantic analysis.
Some common methods of analyzing texts in the social sciences include content analysis, thematic analysis, and discourse analysis. The semantic analysis does throw better results, but it also requires substantially more training and computation. Syntactic analysis involves analyzing the grammatical syntax of a sentence to understand its meaning. B2B and B2C companies are not the only ones to deploy systems of semantic analysis to optimize the customer experience. Google developed its own semantic tool to improve the understanding of user searchers.
Using a low-code UI, you can create models to automatically analyze your text for semantics and perform techniques like sentiment and topic analysis, or keyword extraction, in just a few simple steps. In semantic analysis with machine learning, computers use word sense disambiguation to determine which meaning is correct in the given context. It’s not just about understanding text; it’s about inferring intent, unraveling emotions, and enabling machines to interpret human communication with remarkable accuracy and depth. From optimizing data-driven strategies to refining automated processes, semantic analysis serves as the backbone, transforming how machines comprehend language and enhancing human-technology interactions.

The very first reason is that with the help of meaning representation the linking of linguistic elements to the non-linguistic elements can be done. Insights derived from data also help teams detect areas of improvement and make better decisions. For example, semantic analysis in nlp you might decide to create a strong knowledge base by identifying the most common customer inquiries. As illustrated earlier, the word “ring” is ambiguous, as it can refer to both a piece of jewelry worn on the finger and the sound of a bell.
Using such a tool, PR specialists can receive real-time notifications about any negative piece of content that appeared online. On seeing a negative customer sentiment mentioned, a company can quickly react and nip the problem in the bud before it escalates into a brand reputation crisis. In conclusion, sentiment analysis is a powerful technique that allows us to analyze and understand the sentiment or opinion expressed in textual data. By utilizing Python and libraries such as TextBlob, we can easily perform sentiment analysis and gain valuable insights from the text.
Semantic analysis, the engine behind these advancements, dives into the meaning embedded in the text, unraveling emotional nuances and intended messages. This method involves generating multiple possible next words for a given input and choosing the one that results in the highest overall score. As a systematic mapping, our study follows the principles of a systematic mapping/review.
Also, ‘smart search‘ is another functionality that one can integrate with ecommerce search tools. The use of features based on WordNet has been applied with and without good results [55, 67–69]. Besides, WordNet can support the computation of semantic similarity [70, 71] and the evaluation of the discovered knowledge [72]. You can foun additiona information about ai customer service and artificial intelligence and NLP. The authors present an overview of relevant aspects in textual entailment, discussing four PASCAL Recognising Textual Entailment (RTE) Challenges. They declared that the systems submitted to those challenges use cross-pair similarity measures, machine learning, and logical inference. Lexical semantics plays an important role in semantic analysis, allowing machines to understand relationships between lexical items like words, phrasal verbs, etc.
The authors developed case studies demonstrating how text mining can be applied in social media intelligence. From our systematic mapping data, we found that Twitter is the most popular source of web texts and its posts are commonly used for sentiment analysis or event extraction. This paper reports a systematic mapping study conducted to get a general overview of how text semantics is being treated in text mining studies. It fills a literature review gap in this broad research field through a well-defined review process. Academic research has similarly been transformed by the use of Semantic Analysis tools. Academic Research in Text Analysis has moved beyond traditional methodologies and now regularly incorporates semantic techniques to deal with large datasets.
Meronomy refers to a relationship wherein one lexical term is a constituent of some larger entity like Wheel is a meronym of Automobile. Homonymy refers to the case when words are written in the same way and sound alike but have different meanings. For Example, Tagging Twitter mentions by sentiment to get a sense of how customers feel about your product and can identify unhappy customers in real-time. In the above sentence, the speaker is talking either about Lord Ram or about a person whose name is Ram. Tutorials Point is a leading Ed Tech company striving to provide the best learning material on technical and non-technical subjects. Meaning representation can be used to reason for verifying what is true in the world as well as to infer the knowledge from the semantic representation.
The process starts with the specification of its objectives in the problem identification step. The text mining analyst, preferably working along with a domain expert, must delimit the text mining application scope, including the text collection that will be mined and how the result will be used. Semantic analysis methods will provide companies the ability to understand the meaning of the text and achieve comprehension and communication levels that are at par with humans.
It understands the text within each ticket, filters it based on the context, and directs the tickets to the right person or department (IT help desk, legal or sales department, etc.). Relationship extraction is a procedure used to determine the semantic relationship between words in a text. In semantic analysis, relationships include various entities, such as an individual’s name, place, company, designation, etc. However, due to the vast complexity and subjectivity involved in human language, interpreting it is quite a complicated task for machines. Semantic Analysis of Natural Language captures the meaning of the given text while taking into account context, logical structuring of sentences and grammar roles. At its core, Semantic Text Analysis is the computer-aided process of understanding the meaning and contextual relevance of text.
Word sense disambiguation, a vital aspect, helps determine multiple meanings of words. This proficiency goes beyond comprehension; it drives data analysis, guides customer feedback strategies, shapes customer-centric approaches, automates processes, and deciphers unstructured text. Despite the challenges, the future of semantic analysis in LLMs is promising, with ongoing research and advancements in the field.
Semantic analysis can also benefit SEO (search engine optimisation) by helping to decode the content of a users’ Google searches and to be able to offer optimised and correctly referenced content. The goal is to boost traffic, all while improving the relevance of results for the user. A company can scale up its customer communication by using semantic analysis-based tools. Moreover, while these are just a few areas where the analysis finds significant applications.
- In fact, it’s not too difficult as long as you make clever choices in terms of data structure.
- Usually, relationships involve two or more entities such as names of people, places, company names, etc.
- The process enables computers to identify and make sense of documents, paragraphs, sentences, and words as a whole.
- A ‘search autocomplete‘ functionality is one such type that predicts what a user intends to search based on previously searched queries.
- Based on the understanding, it can then try and estimate the meaning of the sentence.
- Besides, the analysis of the impact of languages in semantic-concerned text mining is also an interesting open research question.
That leads us to the need for something better and more sophisticated, i.e., Semantic Analysis. The authors compare 12 semantic tagging tools and present some characteristics that should be considered when choosing such type of tools. Ontologies can be used as background knowledge in a text mining process, and the text mining techniques can be used to generate and update ontologies. This technique is used separately or can be used along with one of the above methods to gain more valuable insights. Semantic web content is closely linked to advertising to increase viewer interest engagement with the advertised product or service. Types of Internet advertising include banner, semantic, affiliate, social networking, and mobile.
LLMs use a type of neural network architecture known as Transformer, which enables them to understand the context and relationships between words in a sentence. This understanding is crucial for the model to generate coherent and contextually relevant responses. Besides the top 2 application domains, other domains that show up in our mapping refers to the mining of specific types of texts. We found research studies https://chat.openai.com/ in mining news, scientific papers corpora, patents, and texts with economic and financial content. Specifically for the task of irony detection, Wallace [23] presents both philosophical formalisms and machine learning approaches. The author argues that a model of the speaker is necessary to improve current machine learning methods and enable their application in a general problem, independently of domain.
It is the first part of semantic analysis, in which we study the meaning of individual words. It is the first part of the semantic analysis in which the study of the meaning of individual words is performed. Automatically classifying tickets using semantic analysis tools alleviates agents from repetitive tasks and allows them to focus on tasks that provide more value while improving the whole customer experience.
Semantic analysis techniques are also used to accurately interpret and classify the meaning or context of the page’s content and then populate it with targeted advertisements. Differences, as well as similarities between various lexical-semantic structures, are also analyzed. The meaning representation can be used to reason for verifying what is correct in the world as well as to extract the knowledge with the help of semantic representation. With the help of meaning representation, we can represent unambiguously, canonical forms at the lexical level. The first part of semantic analysis, studying the meaning of individual words is called lexical semantics.
It allows these models to understand and interpret the nuances of human language, enabling them to generate human-like text responses. Once trained, LLMs can be used for a variety of tasks that require an understanding of language semantics. These tasks include text generation, text completion, and question answering, among others. For instance, ChatGPT can generate human-like text based on a given prompt, complete a text with relevant information, or answer a question based on the context provided.
Several companies are using the sentiment analysis functionality to understand the voice of their customers, extract sentiments and emotions from text, and, in turn, derive actionable data from them. It helps capture the tone of customers when they post reviews and opinions on social media posts or company websites. Google incorporated ‘semantic analysis’ into its framework by developing its tool to understand and improve user searches. These two techniques can be used in the context of customer service to refine the comprehension of natural language and sentiment. Driven by the analysis, tools emerge as pivotal assets in crafting customer-centric strategies and automating processes. Moreover, they don’t just parse text; they extract valuable information, discerning opposite meanings and extracting relationships between words.
Its potential reaches into numerous other domains where understanding language’s meaning and context is crucial. It recreates a crucial role in enhancing the understanding of data for machine learning models, thereby making them capable of reasoning and understanding context more effectively. As you stand on the brink of this analytical revolution, it is essential to recognize the prowess you now hold with these tools and techniques at your disposal.
Semantic analysis enables these systems to comprehend user queries, leading to more accurate responses and better conversational experiences. Semantic analysis allows for a deeper understanding of user preferences, enabling personalized recommendations in e-commerce, content curation, and more. Indeed, discovering a chatbot capable of understanding emotional intent or a voice bot’s discerning tone might seem like a sci-fi concept.
