Semantic Analysis Uncovering Meaning and Context in Data

Semantic Text Analysis Artificial Intelligence AI

The coverage of Scopus publications are balanced between Health Sciences (32% of total Scopus publication) and Physical Sciences (29% of total Scopus publication). Text mining initiatives can get some advantage by using external sources of knowledge. Thesauruses, taxonomies, ontologies, and semantic networks are knowledge sources that are commonly used by the text mining community. Semantic networks is a network whose nodes are concepts that are linked by semantic relations. The most popular example is the WordNet [63], an electronic lexical database developed at the Princeton University.

Text communication via Web-based networking media, on the other hand, is somewhat overwhelming. Every second, a massive amount of unstructured data is generated on the Internet due to social media platforms. The data must be processed as rapidly as generated to comprehend human psychology, and it can be accomplished using sentiment analysis, which recognizes polarity in texts. It assesses whether the author has a negative, positive, or neutral attitude toward an item, administration, individual, or location. In some applications, sentiment analysis is insufficient and hence requires emotion detection, which determines an individual’s emotional/mental state precisely.

Latent semantic analysis for text-based research

As well as WordNet, HowNet is usually used for feature expansion [83–85] and computing semantic similarity [86–88]. Leser and Hakenberg [25] presents a survey of biomedical named entity recognition. The authors present the difficulties of both identifying entities (like genes, proteins, and diseases) and evaluating named entity recognition systems. They describe some annotated corpora and named entity recognition tools and state that the lack of corpora is an important bottleneck in the field.

Ontologies can be used to create a semantic network, which is a graph-based representation of the relationships between words and their meanings. By incorporating ontologies into AI-driven text understanding models, these systems can better understand the context and meaning of words, leading to more accurate and reliable interpretations of text data. Figure 4 presents various techniques for sentiment analysis and emotion detection which are broadly classified into a lexicon-based approach, machine learning-based approach, deep learning-based approach. The hybrid approach is a combination of statistical and machine learning approaches to overcome the drawbacks of both approaches. Transfer learning is also a subset of machine learning which allows the use of the pre-trained model in other similar domain. A semantic analysis, also known as linguistic analysis, is a technique for determining the meaning of a text.

Machine Learning: Overcoming The Challenge Of Word Meaning

The third step in the compiler development process is the Semantic Analysis step. Declarations and statements made in programs are semantically correct if semantic analysis is used. In semantic analysis, type checking is an important component because it verifies the program’s operations based on the semantic conventions.

Natural language analysis is a tool used by computers to grasp, perceive, and control human language. This paper discusses various techniques addressed by different researchers on NLP and compares their performance. The comparison among the reviewed researches illustrated that good accuracy levels haved been achieved.

This challenge is a frequent roadblock for artificial intelligence (AI) initiatives that tackle language-intensive processes. Semantic analysis systems are used by more than just B2B and B2C companies to improve the customer experience. In Natural Language, the meaning of a word may vary as per its usage in sentences and the context of the text. Word Sense Disambiguation involves interpreting the meaning of a word based upon the context of its occurrence in a text. A ‘search autocomplete‘ functionality is one such type that predicts what a user intends to search based on previously searched queries.

What are the two main types of semantics?

Two of the fundamental issues in the field of semantics are that of compositional semantics (which applies to how smaller parts, like words, combine and interact to form the meaning of larger expressions, such as sentences) and lexical semantics (the nature of the meaning of words).

NLP can also be trained to pick out unusual information, allowing teams to spot fraudulent claims. While NLP and other forms of AI aren’t perfect, natural language processing can bring objectivity to data analysis, providing more accurate and consistent results. Semantic analysis seeks to understand language’s meaning, whereas sentiment analysis seeks to understand emotions.

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.

  • Semantic Analysis is a subfield of Natural Language Processing (NLP) that attempts to understand the meaning of Natural Language.
  • In both the cases above, the algorithm classifies these messages as being contextually related to the concept called Price even though the word Price is not mentioned in these messages.
  • Semantic analysis can be used in a variety of applications, including machine learning and customer service.
  • Earlier, tools such as Google translate were suitable for word-to-word translations.
  • 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.

Semantic analysis in Natural Language Processing (NLP) is understanding the meaning of words, phrases, sentences, and entire texts in human language. It goes beyond the surface-level analysis of words and their grammatical structure (syntactic analysis) and focuses on deciphering the deeper layers of language comprehension. With search engines increasingly relying on semantic analysis, implementing effective search engine optimization (SEO) strategies becomes paramount.

Languages with rich idiomatic expressions and cultural nuances may require specialized adaptations of algorithms to achieve accurate results. In finance, NLP can be paired with machine learning to generate financial reports based on invoices, statements and other documents. Financial analysts can also employ natural language processing to predict stock market trends by analyzing news articles, social media posts and other online sources for market sentiments.

The characteristic concepts of each group can be used to give a quick overview of the content covered in each collection. A graphical representation shows which group a text belongs to and thus allows you to find texts that deal with related topics. Alternatively, we can use a set of terms to describe the content we are looking for and find texts with these terms, as well as with terms that we have not mentioned but are close in content (e.g., synonyms, sub-names, super-names). Semantic analysis is a type of linguistic analysis that focuses on the meaning of words and phrases. The goal of semantic analysis is to identify the meaning of words and phrases in order to better understand the text as a whole.

How do you teach semantics?

  1. understand signifiers.
  2. recognize and name categories or semantic fields.
  3. understand and use descriptive words (including adjectives and other lexical items)
  4. understand the function of objects.
  5. recognize words from their definition.
  6. classify words.
