Latent Semantic Analysis for Text Mining and Beyond: Computer Science & IT Book Chapter

Semantic web and cloud technology systems have been critical components in creating and deploying applications in various fields. Although they are selfcontained, they can be combined in various ways to create solutions, which has recently been discussed in depth. As a result, issues with portability, interoperability, security, selection, negotiation, discovery, and definition of cloud services and resources may arise.

When it comes to definitions, semantics students analyze subtle differences between meanings, such as howdestination and last stop technically refer to the same thing. Semantics can be used in sentences to represent a child’s understanding of a mother’s directive to “do your chores” to represent the child’s ability to perform those duties whenever they are convenient. It can be applied to the study of individual words, groups of words, and even whole texts.

SEMANTIC VARIANCE MEASUREMENTS FOR EVALUATING SINGLE-DOCUMENT SUMMARIZATION

It allows you to obtain sentence embeddings and contextual word embeddings effortlessly. Stanford CoreNLP is a suite of NLP tools that can perform tasks like part-of-speech tagging, named entity recognition, and dependency parsing. SpaCy is another Python library known for its high-performance NLP capabilities. It offers pre-trained models for part-of-speech tagging, named entity recognition, and dependency parsing, all essential semantic analysis components. The synergy between humans and machines in the semantic analysis will develop further.

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. Text mining techniques have become essential for supporting knowledge discovery as the volume and variety of digital text documents have increased, either in social networks and the Web or inside organizations. Although there is not a among the different research communities [1], text mining can be seen as a set of methods used to analyze unstructured data and discover patterns that were unknown beforehand [2].

Introduction to Semantic Analysis

Rule-based technology such as Expert.ai reads all of the words in content to extract their true meaning. Similarly, the text is assigned logical and grammatical functions to the textual elements. As a result, even businesses with the most complex processes can be automated with the help of language understanding.

SemEval and SST datasets have various variants which differ in terms of domain, size, etc. ISEAR was collected from multiple respondents who felt one of the seven emotions (mentioned in the table) in some situations. The table shows that datasets include mainly the tweets, reviews, feedbacks, stories, etc. A dimensional model named valence, arousal dominance model (VAD) is used in the EmoBank dataset collected from news, blogs, letters, etc. Many studies have acquired data from social media sites such as Twitter, YouTube, and Facebook and had it labeled by language and psychology experts in the literature. Data crawled from various social media platform’s posts, blogs, e-commerce sites are usually unstructured and thus need to be processed to make it structured to reduce some additional computations outlined in the following section.

Semantic Extraction Models

Among these methods, we can find named entity recognition (NER) and semantic role labeling. It shows that there is a concern about developing richer text representations to be input for traditional machine learning algorithms, as we can see in the studies of [55, 139–142]. The application of text mining methods in information extraction of biomedical literature is reviewed by Winnenburg et al. [24].

Along with services, it also improves the overall experience of the riders and drivers. For example, ‘Raspberry Pi’ can refer to a fruit, a single-board computer, or even a company (UK-based foundation). Hence, it is critical to identify which meaning suits the word depending on its usage.

Semantic analysis is a tool that can be used in many different fields, such as literary criticism, history, philosophy, and psychology. It is also a useful tool for understanding the meaning of legal texts and for analyzing political speeches. In vector-based methods of text data analysis, after a suitable set of terms has been defined for a document collection, the collection can be represented as a set of vectors. With traditional vector space methods, individual documents are treated as vectors in a high-dimensional vector space in which each dimension corresponds to some feature of a document, typically a term. A collection of documents can thus be represented by a two-dimensional matrix A(t,d) of features (terms) and documents.

Machine learning enables machines to retain their relevance in context by allowing them to learn new meanings from context. The customer may be directed to a support team member if an AI-powered chatbot can resolve the issue faster. The method is based on the study of hidden meaning (for example, connotation or sentiment). Language data is often difficult to use by business owners to improve their operations. It is possible for a business to gain valuable insight into its products and services. However, it is critical to detect and analyze these comments in order to detect and analyze them.
