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. 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.

Keyword Extraction

Therefore, it was expected that classification and clustering would be the most frequently applied tasks. When the field of interest is broad and the objective is to have an overview of what is being developed in the research field, it is recommended to apply a particular type of systematic review named systematic mapping study [3, 4]. 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.

Spacy Transformers is an extension of spaCy that integrates transformer-based models, such as BERT and RoBERTa, into the spaCy framework, enabling seamless use of these models for semantic analysis. Semantic analysis extends beyond text to encompass multiple modalities, including images, videos, and audio. Integrating these modalities will provide a more comprehensive and nuanced semantic understanding. In the next section, we’ll explore the practical applications of semantic analysis across multiple domains. Currently there are algorithms to identify classifications of text and patterns within a text, but these representations can be ambiguous. Keeping the advantages of natural language processing in mind, let’s explore how different industries are applying this technology.

What is Semantics?

The primary goal of sentiment analysis is to determine whether the sentiment expressed in the text is positive, negative, or neutral. This information can be used by businesses to make decisions related to marketing, customer service, and product development. Healthcare information systems can reduce the expenses of treatment, foresee episodes of pestilences, help stay away from preventable illnesses, and improve personal life satisfaction. In the recent few years, a large number of organizations and companies have shown enthusiasm for using semantic web technologies with healthcare big data to convert data into knowledge and intelligence. Data science involves using statistical and computational methods to analyze large datasets and extract insights from them. However, traditional statistical methods often fail to capture the richness and complexity of human language, which is why semantic analysis is becoming increasingly important in the field of data science.

However, the former is more challenging due to ambiguities present in natural language. Speech recognition, document summarization, question answering, speech synthesis, machine translation, and other applications all employ NLP (Itani et al. 2017). The two critical areas of natural language processing are sentiment analysis and emotion recognition. Even though these two names are sometimes used interchangeably, they differ in a few respects. Sentiment analysis is a means of assessing if data is positive, negative, or neutral. Textual similarity analysis is another prominent application of semantic analysis that measures the degree of similarity or relatedness between two texts.

In social media, semantic analysis is used for trend analysis, influencer marketing, and reputation management. Trend analysis involves identifying the most popular topics and themes on social media, allowing businesses to stay up-to-date with the latest trends. Currently in use, this technology examines the emotion and meaning of communications between people and machines. Uber, the highest valued start-up in the world, has been a pioneer in the sharing economy. Being operational in more than 500 cities worldwide and serving a gigantic user base, Uber gets a lot of feedback, suggestions, and complaints by users. The huge amount of incoming data makes analyzing, categorizing, and generating insights challenging undertaking.

By implementing count() here with arguments of both word and sentiment, we find out how much each word contributed to each sentiment. We now have an estimate of the net sentiment (positive – negative) in each chunk of the novel text for each sentiment lexicon. We can see in Figure 2.2 how the plot of each novel changes toward more positive or negative sentiment over the trajectory of the story. Dictionary-based methods like the ones we are discussing find the [newline]total sentiment of a piece of text by adding up the individual sentiment

scores for each word in the text. Word Sense Disambiguation

Word Sense Disambiguation (WSD) involves interpreting the meaning of a word based on the context of its occurrence in a text. Semantic analysis is done by analyzing the grammatical structure of a piece of text and understanding how one word in a sentence is related to another.

In the past years, natural language processing and text mining becomes popular as it deals with text whose purpose is to communicate actual information and opinion. Using Natural Language Processing (NLP) techniques and Text Mining will increase the annotator productivity. There are lesser known experiments has been made in the field of uncertainty detection. With fast growing world there is lot of scope in the various fields where uncertainty play major role in deciding the probability of uncertain event.

Every day, civil servants and officials are confronted with many voluminous documents that need to be reviewed and applied according to the information requirements of a specific task. Since reviewing many documents and selecting the most relevant ones is a time-consuming task, we have developed an AI-based approach for the content-based review of large collections of texts. The approach of semantic analysis of texts and the comparison of content relatedness between individual texts in a collection allows for timesaving and the comprehensive analysis of collections.

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. Figure 2.4 lets us spot an anomaly in the sentiment analysis; the word “miss” is coded as negative but it is used as a title for young, unmarried women in Jane Austen’s works. If it were appropriate for our purposes, we could easily add “miss” to a custom stop-words list using bind_rows(). Why is, for example, the result for the NRC lexicon biased so high in sentiment compared to the Bing et al. result?

The goal is to develop a general-purpose tool for analysing sets of textual documents. A semantic analysis is an analysis of the meaning of words and phrases in a document or text. This tool is capable of extracting information such as the topic of a text, its structure, and the relationships between words and phrases. Following this, the information can be used to improve the interpretation of the text and make better decisions. Semantic analysis can be used in a variety of applications, including machine learning and customer service. Text classification and text clustering, as basic text mining tasks, are frequently applied in semantics-concerned text mining researches.

Text search engines serve as information filters to sift out an initial set of relevant documents, while text summarizers play the role of information spotters to help users spot a final set of desired documents (Gong & Liu, 2001). With semantic analysis, AI systems can generate accurate and meaningful summaries of lengthy text, saving users time and effort. It’s like having a personal assistant who can distill complex information into simple, digestible nuggets. Semantic analysis helps improve search engines and information retrieval systems by considering the meaning and context of search queries. It’s like having a knowledgeable librarian who knows exactly where to find the information you need.

Insights derived from data also help teams detect areas of improvement and make better decisions. For example, you might decide to create a strong knowledge base by identifying the most common customer inquiries. You understand that a customer is frustrated because a customer service agent is taking too long to respond.

What your looking for is a Natural Language Processing (NLP) tool, there are a few tools around that could be some help such as SharpNLP but I’m not aware if there is a specific tool for detecting and replacing synonyms. This information can be used by businesses to personalize customer experiences, improve customer service, and develop effective marketing strategies.

Tailoring NLP models to understand the intricacies of specialized terminology and context is a growing trend. As semantic analysis evolves, it holds the potential to transform the way we interact with machines and leverage the power of language understanding across diverse applications. Semantic analysis continues to find new uses and innovations across diverse domains, empowering machines to interact with human language increasingly sophisticatedly. As we move forward, we must address the challenges and limitations of semantic analysis in NLP, which we’ll explore in the next section. Natural language processing brings together linguistics and algorithmic models to analyze written and spoken human language. Based on the content, speaker sentiment and possible intentions, NLP generates an appropriate response.

What is semantic analysis in English?

Semantic analysis, expressed, is the process of extracting meaning from text. Grammatical analysis and the recognition of links between specific words in a given context enable computers to comprehend and interpret phrases, paragraphs, or even entire manuscripts.

This type of literature review is not as disseminated in the computer science field as it is in the medicine and health care fields1, although computer science researches can also take advantage of this type of review. We can find important reports on the use of systematic reviews specially in the software engineering community [3, 4, 6, 7]. Other sparse initiatives can also be found in other computer science areas, as cloud-based environments [8], image pattern recognition [9], biometric authentication [10], recommender systems [11], and opinion mining [12].
