PDF Semantic Analysis of Sentiments through Web-Mined Twitter Corpus

By enabling computers to understand the meaning of words and phrases, semantic analysis can help us extract valuable insights from unstructured data sources such as social media posts, news articles, and customer reviews. As such, it is a vital tool for businesses, researchers, and policymakers seeking to leverage the power of data to drive innovation and growth. One of the most common applications of semantics in data science is natural language processing (NLP).

Apple can refer to a number of possibilities including the fruit, multiple companies (Apple Inc, Apple Records), their products, along with some other interesting meanings . Big data analytics, scientific search and literature analysis – for too long, it has been a challenge to integrate, extract and analyse knowledge locked within unstructured biomedical text. Extensive business analytics enables an organization to gain precise insights into their customers. Consequently, they can offer the most relevant solutions to the needs of the target customers. There is no other option than to secure a comprehensive engagement with your customers. Businesses can win their target customers’ hearts only if they can match their expectations with the most relevant solutions.

Semantic analysis employs various methods, but they all aim to comprehend the text’s meaning in a manner comparable to that of a human. This can entail figuring out the text’s primary ideas and themes and their connections. This is often accomplished by locating and extracting the key ideas and connections found in the text utilizing algorithms and AI approaches.

Semantic analysis tech is highly beneficial for the customer service department of any company. Moreover, it is also helpful to customers as the technology enhances the overall customer experience at different levels. Large-scale classification applies to ontologies that contain gigantic numbers of categories, usually ranging in tens or hundreds of thousands.

Lexical Semantics

Expressions that were only provided by a single participant or by very few participants we consider as accidental/occasional expressions (Sutrop, 2001, p. 263). The selection was based on the assumption that the most important connotations are expressions that are actively used, and are therefore listed more frequently. The opposite is also true, rarely used connotations represent less important notions. The current research focuses on a study of the internal structure and diversification of the most important semantic domains of the notion of beauty, and the discovery of some of the connections between particular domains in the Turkish language.

Building an Explicit Semantic Analysis (ESA) model on a large collection of text documents can result in a model with many features or titles. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. A lack of significant differences between genders and age groups cannot be generalized for this study because the research sample was not sufficiently extensive and was not balanced with regard to these variables.

In semantic analysis, relationships include various entities, such as an individual’s name, place, company, designation, etc. Moreover, semantic categories such as, ‘is the chairman of,’ ‘main branch located a’’, ‘stays at,’ and others connect the above entities. Apart from these vital elements, the semantic analysis also uses semiotics and collocations to understand and interpret language.

Generally these notations are textual, in the sense that they build up expressions from a finite alphabet, though there may be pictorial reasons why one symbol was chosen rather than another.

Techniques of Semantic Analysis

LSA can evaluate a word whose meaning is determined contextually (e.g., «we moved back,» is differentiated from «hurt my back»). Furthermore, it can determine similarity among responses without accounting for word order or even if passages share no words in common [22]. A second task, which required completion of the first, asked participants to express, via a Likert scale, to what extent a list of provided words (adjectives and nouns), conveyed (a) the notion of beauty, and (b) the notion of ugliness. The list was based on an earlier, preliminary study with specific words selected as mutual opposites, so as to represent extremes of a continuum. Unlike Osgood’s classic semantic differential, participants were also allowed to react to connotations that represented nouns, as those occurred nearly as frequently as adjectives in the free associations. Through a study of semantic differential, the focus became a more delicate mapping of the individual dimensions of the notion of beauty and ugliness and a measurement of these differences (Osgood et al., 1957).

The third group of words that often appeared among the free associations were ideas referring to activity or passivity. Beauty is often connected with something that energizes such as “desire,” “passion,” “attractiveness” (11), “excitement” (8), “sexiness,” “movement,” etc. Eagerness and anxiousness activates an effort to achieve greater pleasure, or more permanent ownership of it. On the contrary, the enjoyment of beauty in the present, without time limitations, calms us and allows for contemplation of beauty in the Greek sense theorion.

Intellias developed the text mining NLP solution

On the basis of BP neural network, we construct a prediction model of user’s quasi-social relationship type. The performance test data of the model shows that the average prediction accuracy of the constructed model is 89.84%, and the model has low time complexity and higher processing efficiency, which is better than other traditional models. This paper presents the work done on recommendations of healthcare related journal papers by understanding the semantics of terms from the papers referred by users in past. In other words, user profiles based on user interest within the healthcare domain are constructed from the kind of journal papers read by the users.
