Understanding Semantic Analysis NLP

semantic text analysis

A strong grasp of semantic analysis helps firms improve their communication with customers without needing to talk much. 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. Therefore, the goal of semantic analysis is to draw exact meaning or dictionary meaning from the text. This article is part of an ongoing blog series on Natural Language Processing (NLP).

This is often accomplished by locating and extracting the key ideas and connections found in the text utilizing algorithms and AI approaches. Tickets can be instantly routed to the right hands, and urgent issues can be easily prioritized, shortening response times, and keeping satisfaction levels high. Semantic analysis also takes into account signs and symbols (semiotics) and collocations (words that often go together).

Besides, we can find some studies that do not use any linguistic resource and thus are language independent, as in [57–61]. These facts can justify that English was mentioned in only 45.0% of the considered studies. Some studies accepted in this systematic mapping are cited along the presentation of our mapping. We do not present the reference of every accepted paper in order to present a clear reporting of the results. After the selection phase, 1693 studies were accepted for the information extraction phase.

This ends our Part-9 of the Blog Series on Natural Language Processing!

Researchers in these fields take media and cultural objects – for example, music videos, social media content, billboard advertising – and treat them as texts to be analyzed. In the case of syntactic analysis, the syntax of a sentence is used to interpret a text. In the case of semantic analysis, the overall context of the text is considered during the analysis. Natural Language Processing or NLP is a branch of computer science that deals with analyzing spoken and written language.

Search engines determine the quality and relevance of a text by the words and phrases it contains. 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. In this component, we combined the individual words to provide meaning in sentences. Lexical analysis is based on smaller tokens but on the contrary, the semantic analysis focuses on larger chunks.

What is Semantic Analysis?

In the above sentence, the speaker is talking either about Lord Ram or about a person whose name is Ram. Likewise, the word ‘rock’ may mean ‘a stone‘ or ‘a genre of music‘ – hence, the accurate meaning of the word is highly dependent upon its context and usage in the text. You can foun additiona information about ai customer service and artificial intelligence and NLP. Hence, under Compositional Semantics Analysis, we try to understand how combinations of individual words form the meaning of the text. The landscape of text analysis is poised for transformative growth, driven by advancements in Natural Language Understanding and the integration of semantic capabilities with burgeoning technologies like the IoT.

The conduction of this systematic mapping followed the protocol presented in the last subsection and is illustrated in Fig. The selection and the information extraction phases were performed with support of the Start tool [13]. Semantic analysis transforms data (written or verbal) into concrete action plans.

These obstacles underline the importance of continuous enhancement in the field. Understanding how to apply these techniques can significantly enhance your proficiency in data mining and the analysis of textual content. As you continue to explore the field of semantic text analysis, keep these key methodologies at the forefront of your analytical toolkit.

Meaning Representation

The authors discuss a series of questions concerning natural language issues that should be considered when applying the text mining process. Most of the questions are related to text pre-processing and the authors present the impacts of performing or not some pre-processing activities, such as stopwords removal, stemming, word sense disambiguation, and tagging. The authors also discuss some existing text representation approaches in terms of features, representation model, and application task. The set of different approaches to measure the similarity between documents is also presented, categorizing the similarity measures by type (statistical or semantic) and by unit (words, phrases, vectors, or hierarchies). Grobelnik [14] also presents the levels of text representations, that differ from each other by the complexity of processing and expressiveness. The most simple level is the lexical level, which includes the common bag-of-words and n-grams representations.

The Hummingbird algorithm was formed in 2013 and helps analyze user intentions as and when they use the google search engine. As a result of Hummingbird, results are shortlisted based on the ‘semantic’ relevance of the keywords. Moreover, it also plays a crucial role in offering SEO benefits to the company. Upon parsing, the analysis then proceeds to the interpretation step, which is critical for artificial intelligence algorithms. For example, the word ‘Blackberry’ could refer to a fruit, a company, or its products, along with several other meanings. Moreover, context is equally important while processing the language, as it takes into account the environment of the sentence and then attributes the correct meaning to it.

Bos [31] indicates machine learning, knowledge resources, and scaling inference as topics that can have a big impact on computational semantics in the future. Thanks to tools like chatbots and dynamic FAQs, your customer service is supported in its day-to-day management of customer inquiries. The semantic analysis technology behind these solutions provides a better understanding of users and user needs. These solutions can provide instantaneous and relevant solutions, autonomously and 24/7. Semantic analysis, a natural language processing method, entails examining the meaning of words and phrases to comprehend the intended purpose of a sentence or paragraph.

The first step of a systematic review or systematic mapping study is its planning. The main parts of the protocol that guided the systematic mapping study reported in this paper are presented in the following. In this section, we also present the protocol applied to conduct the systematic mapping study, including the research questions that guided this study and how it was conducted. The results of the systematic mapping, as well as identified future trends, are presented in the “Results and discussion” section. In this step, raw text is transformed into some data representation format that can be used as input for the knowledge extraction algorithms. The activities performed in the pre-processing step are crucial for the success of the whole text mining process.

For us humans, there is nothing more simple than recognising the meaning of a sentence based on the punctuation or intonation used. 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. With the evolution of Semantic Search engines, user experience on the web has been substantially improved.

Each element is designated a grammatical role, and the whole structure is processed to cut down on any confusion caused by ambiguous words having multiple meanings. The challenge of semantic analysis is understanding a message by interpreting its tone, meaning, emotions and sentiment. Today, this method reconciles humans and technology, proposing efficient solutions, notably when it comes to a brand’s customer service.

It goes beyond merely recognizing words and phrases to comprehend the intent and sentiment behind them. By leveraging this advanced interpretative approach, businesses and researchers can gain significant insights from textual data interpretation, distilling complex information into actionable knowledge. By venturing into Semantic Text Analysis, you’re taking the first step towards unlocking the full potential of language in an age shaped by big data and artificial intelligence. Whether it’s refining customer feedback, streamlining content curation, or breaking new ground in machine learning, semantic analysis stands as a beacon in the tumultuous sea of information. Text mining is a process to automatically discover knowledge from unstructured data.

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. Expert.ai’s rule-based technology starts by reading all of the words within a piece of content to capture its real meaning. It then identifies the textual elements and assigns them to their logical and grammatical roles. Finally, it analyzes the surrounding text and text structure to accurately determine the proper meaning of the words in context. While, as humans, it is pretty simple for us to understand the meaning of textual information, it is not so in the case of machines. Thus, machines tend to represent the text in specific formats in order to interpret its meaning.

The next most useful feature selected by Chi-square test is “great”, I assume it is from mostly the positive reviews. We will calculate the Chi square scores for all the features and visualize the top 20, here terms or words or N-grams are features, semantic text analysis and positive and negative are two classes. Given a feature X, we can use Chi square test to evaluate its importance to distinguish the class. Among the three words, “peanut”, “jumbo” and “error”, tf-idf gives the highest weight to “jumbo”.

The authors present a chronological analysis from 1999 to 2009 of directed probabilistic topic models, such as probabilistic latent semantic analysis, latent Dirichlet allocation, and their extensions. Traditionally, text mining techniques are based on both a bag-of-words representation and application of data mining techniques. In order to get a more complete analysis of text collections and get better text mining results, several researchers directed their attention to text semantics. When combined with machine learning, semantic analysis allows you to delve into your customer data by enabling machines to extract meaning from unstructured text at scale and in real time. 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. In the fields of cultural studies and media studies, textual analysis is a key component of research.

Semantic analysis significantly improves language understanding, enabling machines to process, analyze, and generate text with greater accuracy and context sensitivity. Indeed, semantic analysis is pivotal, fostering better user experiences and enabling more efficient information retrieval and processing. Semantic analysis techniques involve extracting meaning from text through grammatical analysis and discerning connections between words in context. This process empowers computers to interpret words and entire passages or documents. Word sense disambiguation, a vital aspect, helps determine multiple meanings of words.

Therefore, in semantic analysis with machine learning, computers use Word Sense Disambiguation to determine which meaning is correct in the given context. However, many organizations struggle to capitalize on it because of their inability to analyze unstructured data. This challenge is a frequent roadblock for artificial intelligence (AI) initiatives that tackle language-intensive processes.

Imagine being able to distill the essence of vast texts into clear, actionable insights, tearing down the barriers of data overload with precision and understanding. Introduction to Semantic Text Analysis unveils a world where the complexities and nuances of language are no longer lost in translation between humans and computers. It’s here that we begin our journey into the foundation of language understanding, guided by the promise of Semantic Analysis benefits to enhance communication and revolutionize our interaction with the digital realm. The use of Wikipedia is followed by the use of the Chinese-English knowledge database HowNet [82]. Finding HowNet as one of the most used external knowledge source it is not surprising, since Chinese is one of the most cited languages in the studies selected in this mapping (see the “Languages” section). As well as WordNet, HowNet is usually used for feature expansion [83–85] and computing semantic similarity [86–88].

The protocol is a documentation of the review process and must have all the information needed to perform the literature review in a systematic way. The analysis of selected studies, which is performed in the data extraction phase, will provide the answers to the research questions that motivated the literature review. Kitchenham and Charters [3] present a very useful guideline for planning and conducting systematic literature reviews. As systematic reviews follow a formal, well-defined, and documented protocol, they tend to be less biased and more reproducible than a regular literature review. MonkeyLearn makes it simple for you to get started with automated semantic analysis tools. 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.

Semantic analysis analyzes the grammatical format of sentences, including the arrangement of words, phrases, and clauses, to determine relationships between independent terms in a specific context. It is also a key component of several machine learning tools available today, such as search engines, chatbots, and text analysis software. The application of text mining methods in information extraction of biomedical literature is reviewed by Winnenburg et al. [24].

Moreover, QuestionPro might connect with other specialized semantic analysis tools or NLP platforms, depending on its integrations or APIs. This integration could enhance the analysis by leveraging more advanced semantic processing capabilities from external tools. QuestionPro, a survey and research platform, might have certain features or functionalities that could complement or support the semantic analysis process. Semantic analysis systems are used by more than just B2B and B2C companies to improve the customer experience.

Text semantics is closely related to ontologies and other similar types of knowledge representation. We also know that health care and life sciences is traditionally concerned about standardization of their concepts and concepts relationships. Thus, as we already expected, health care and life sciences was the most cited application domain among the literature accepted studies. This application domain is followed by the Web domain, what can be explained by the constant growth, in both quantity and coverage, of Web content. Beyond latent semantics, the use of concepts or topics found in the documents is also a common approach.

It allows computers to understand and interpret sentences, paragraphs, or whole documents, by analyzing their grammatical structure, and identifying relationships between individual words in a particular context. Semantic Analysis is a subfield of Natural Language Processing (NLP) that attempts to understand the meaning of Natural Language. Understanding Natural Language might seem a straightforward process to us as humans.

Semantic Analysis Is Part of a Semantic System

This formal structure that is used to understand the meaning of a text is called meaning representation. 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.

Thus, this paper reports a systematic mapping study to overview the development of semantics-concerned studies and fill a literature review gap in this broad research field through a well-defined review process. Semantics can be related to a vast number of subjects, and most of them are studied in the natural language processing field. As examples of semantics-related subjects, we can mention representation of meaning, semantic parsing and interpretation, word sense disambiguation, and coreference resolution. Nevertheless, the focus of this paper is not on semantics but on semantics-concerned text mining studies. This paper aims to point some directions to the reader who is interested in semantics-concerned text mining researches. The results of the systematic mapping study is presented in the following subsections.

This process is incomplete without the delicate task of interpreting the results. It demands a sharp eye and a deep understanding of both the data at hand and the context it operates within. Your text data workflow culminates in the articulation of these interpretations, translating complex semantic relationships into actionable insights. Understanding the textual data you encounter is a foundational aspect of Semantic Text Analysis.

In this model, each document is represented by a vector whose dimensions correspond to features found in the corpus. When features are single words, the text representation is called bag-of-words. Despite the good results achieved with a bag-of-words, this representation, based on independent words, cannot express word relationships, text syntax, or semantics. Therefore, it is not a proper representation for all possible text mining applications. The formal semantics defined by Sheth et al. [28] is commonly represented by description logics, a formalism for knowledge representation. The application of description logics in natural language processing is the theme of the brief review presented by Cheng et al. [29].

It gives computers and systems the ability to understand, interpret, and derive meanings from sentences, paragraphs, reports, registers, files, or any document of a similar kind. Text semantics are frequently addressed in text mining studies, since it has an important influence in text meaning. However, there is a lack of secondary studies that consolidate these researches. This paper reported a systematic mapping study conducted to overview semantics-concerned text mining literature. Thus, due to limitations of time and resources, the mapping was mainly performed based on abstracts of papers. Nevertheless, we believe that our limitations do not have a crucial impact on the results, since our study has a broad coverage.

They outline a future where the breadth of semantic understanding matches the depths of human communication, paving the way for limitless explorations into the vast digital expanse of text and beyond. The concept of Semantic IoT Integration proposes a deeply interconnected network of devices that can communicate with one another in more meaningful ways. Semantic analysis will be critical in interpreting the vast amounts of unstructured data generated by IoT devices, turning it into valuable, actionable insights. Imagine smart homes and cities where devices not only collect data but understand and predict patterns in energy usage, traffic flows, and even human behaviors.

Systematic mapping studies follow an well-defined protocol as in any systematic review. The main differences between a traditional systematic review and a systematic mapping are their breadth and depth. While a systematic review deeply analyzes a low number of primary studies, in a systematic mapping a wider number of studies are analyzed, but less detailed. Thus, the search terms of a systematic mapping are broader and the results are usually presented through graphs. A systematic review is performed in order to answer a research question and must follow a defined protocol. The protocol is developed when planning the systematic review, and it is mainly composed by the research questions, the strategies and criteria for searching for primary studies, study selection, and data extraction.

I hope after reading that article you can understand the power of NLP in Artificial Intelligence. So, in this part of this series, we will start our discussion on Semantic analysis, which is a level of the NLP tasks, and see all the important terminologies or concepts in this analysis. 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. 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 Natural Language, the meaning of a word may vary as per its usage in sentences and the context of the text.

Your grasp of the Semantic Analysis Process can significantly elevate the caliber of insights derived from your text data. By following these steps, you array yourself with the capacity to harness the true power of words in a sea of digital information, making semantic analysis an invaluable asset in any data-driven strategy. In real application of the text mining process, the participation of domain experts can be crucial to its success. However, the participation of users (domain experts) is seldom explored in scientific papers. The difficulty inherent to the evaluation of a method based on user’s interaction is a probable reason for the lack of studies considering this approach. Besides the vector space model, there are text representations based on networks (or graphs), which can make use of some text semantic features.

Firstly, the destination for any Semantic Analysis Process is to harvest text data from various sources. This data could range from social media posts and customer reviews to academic articles and technical documents. Once gathered, it embarks on the voyage of preprocessing, where it is cleansed and normalized to ensure consistency and accuracy for the semantic algorithms that follow.

The water analysis reveals the quantity of stop-words, colloquial expressions and redundant constructions. Deleting those do not impair the content’s meaning, enhancing its quality instead. Insert the keywords in the Highlight Keywords field to assess their density, and the service will highlight them automatically. We can observe that the features with a high χ2 can be considered relevant for the sentiment classes we are analyzing. To classify sentiment, we remove neutral score 3, then group score 4 and 5 to positive (1), and score 1 and 2 to negative (0).
