Understanding Semantic Analysis NLP

Unnecessary words like articles and some prepositions that do not contribute toward emotion recognition and sentiment analysis must be removed. For instance, stop words like «is,» «at,» «an,» «the» have nothing to do with sentiments, so these need to be removed to avoid unnecessary computations (Bhaskar et al. 2015; Abdi et al. 2019). This step is beneficial in finding various aspects from a sentence that are generally described by nouns or noun phrases while sentiments and emotions are conveyed by adjectives (Sun et al. 2017). We anticipate the emergence of more advanced pre-trained language models, further improvements in common sense reasoning, and the seamless integration of multimodal data analysis. As semantic analysis develops, its influence will extend beyond individual industries, fostering innovative solutions and enriching human-machine interactions. It specializes in deep learning for NLP and provides a wide range of pre-trained models and tools for tasks like semantic role labelling and coreference resolution.

Advantages of Semantic Analysis

Semantic analysis starts with tokenization and parsing, breaking down text into individual words or phrases and analyzing their grammatical structure. Figure 2 depicts the numerous emotional states that can be found in various models. These states are plotted on a four-axis by taking the Plutchik model as a base model. The most commonly used emotion states in different models include anger, fear, joy, surprise, and disgust, as depicted in the figure above.

• In this article, semantic interpretation is carried out in the area of Natural Language Processing.
• Capturing the information is the easy part but understanding what is being said (and doing this at scale) is a whole different story.
• A vast amount of information exists in text form, such as free (unstructured) or semi-structured text, including many database fields, reports, memos, email, web sites, blogs, and news articles.
• With several options for sentiment lexicons, you might want some more information on which one is appropriate for your purposes.
• I hope after reading that article you can understand the power of NLP in Artificial Intelligence.

Homonymy deals with different meanings and polysemy deals with related meanings. It is also sometimes difficult to distinguish homonymy from polysemy because the latter also deals with a pair of words that are written and pronounced in the same way. Antonyms refer to pairs of lexical terms that have contrasting meanings or words that have close to opposite meanings. Studying a language separated from studying the meaning of that language because when one is learning a language, we are also learning the meaning of the language. WSD approaches are categorized mainly into three types, Knowledge-based, Supervised, and Unsupervised methods.

Latent semantic analysis for text-based research

Otherwise, another cycle must be performed, making changes in the data preparation activities and/or in pattern extraction parameters. If any changes in the stated objectives or selected text collection must be made, the text mining process should be restarted at the problem identification step. Nowadays, web users and systems continually overload the web with an exponential generation of a massive amount of data. This leads to making big data more important in several domains such as social networks, internet of things, health care, E-commerce, aviation safety, etc. The use of big data has become increasingly crucial for companies due to the significant evolution of information providers and users on the web.

In the realm of artificial intelligence (AI) and natural language processing (NLP), semantic analysis plays a crucial role in enabling machines to understand and interpret human language. By analyzing the meaning and context of words and sentences, semantic analysis empowers AI systems to extract valuable insights from textual data. In this article, we will delve into the intricacies of semantic analysis, exploring its key concepts and terminology, and delving into its various applications across industries.

There are many different semantic analysis techniques that can be used to analyze text data. Some common techniques include topic modeling, sentiment analysis, and text classification. These techniques can be used to extract meaning from text data and to understand the relationships between different concepts. As previously stated, the objective of this systematic mapping is to provide a general overview of semantics-concerned text mining studies. The papers considered in this systematic mapping study, as well as the mapping results, are limited by the applied search expression and the research questions.

As a result, corpus-based approaches are more accurate but lack generalization. The performance of machine learning algorithms and deep learning algorithms depends on the pre-processing and size of the dataset. Nonetheless, in some cases, machine learning models fail to extract some implicit features or aspects of the text. In situations where the dataset is vast, the deep learning approach performs better than machine learning. Recurrent neural networks, especially the LSTM model, are prevalent in sentiment and emotion analysis, as they can cover long-term dependencies and extract features very well. At the same time, it is important to keep in mind that the lexicon-based approach and machine learning approach (traditional approaches) are also evolving and have obtained better outcomes.

This approach enhances the overall quality and accuracy of text-related applications, contributing to more reliable search results and data analysis. Whether using machine learning or statistical techniques, the text mining approaches are usually language independent. However, specially in the natural language processing field, annotated corpora is often required to train models in order to resolve a certain task for each specific language (semantic role labeling problem is an example). Besides, linguistic resources as semantic networks or lexical databases, which are language-specific, can be used to enrich textual data. Thus, the low number of annotated data or linguistic resources can be a bottleneck when working with another language. There are important initiatives to the development of researches for other languages, as an example, we have the ACM Transactions on Asian and Low-Resource Language Information Processing [50], an ACM journal specific for that subject.

This allowed us to analyze which words are used most frequently in documents and to compare documents, but now let’s investigate a different topic. When human readers approach a text, we use our understanding of the emotional intent of words to infer whether a section of text is positive or negative, or perhaps characterized by some other more nuanced emotion like surprise or disgust. We can use the tools of text mining to approach the emotional content of text programmatically, as shown in Figure 2.1. 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. Consequently, in order to improve text mining results, many text mining researches claim that their solutions treat or consider text semantics in some way.

During procedures, doctors can dictate their actions and notes to an app, which produces an accurate transcription. NLP can also scan patient documents to identify patients who would be best suited for certain clinical trials. Insurance companies can assess claims with natural language processing since this technology can handle both structured and unstructured data.

In both advanced and emerging nations, the impact of business and client sentiment on stock market performance may be witnessed. In addition, the rise of social media has made it easier and faster for investors to interact in the stock market. As a result, investor’s sentiments impact their investment decisions which can swiftly spread and magnify over the network, and the stock market can be altered to some extent (Ahmed 2020).
