To create a semantic core, it is necessary to collect keywords related to the topic, products or services of the website and analyze their frequency, relevance and competition. Keywords can be divided into commercial and non-commercial, depending on whether they express a purchase intention or simply to find information. Keywords can also be divided into high frequency, medium frequency, and low frequency, based on how often users search for them.

A semantic core should be structured according to the sections and subsections of the website, and each page should be optimized for a specific group of keywords. A semantic core should also be updated periodically, based on changes in user behavior, market trends, and search engine algorithms. A semantic core is an essential part of any SEO strategy, as it helps a website communicate its value proposition to both users and search engines.

HTML semantic core
What is the semantic core? Definition, concept 7

The semantic core in HTML refers to the use of elements that have a clear and specific meaning for both the browser and the developer. Semantic elements describe the content and purpose of different parts of a document, rather than just how they look. For example, ,

Using the semantic core in HTML has several benefits, such as:

– Improve accessibility and readability of the document for users and screen readers

– Improve search engine optimization (SEO) and document ranking

– Make the document easier to maintain and update by separating the structure from the presentation

– Enable document reuse and interoperability across different platforms and devices

The semantic core in HTML is based on the principles of semantics, which is the study of the meanings of words and phrases in a language.


A semantic core reference is a term that refers to the essential meaning of a concept or term in a given context. For example, in the programming field, a central semantic reference for a name can be the type, field, method, or variable it represents. A semantic core reference can help identify and relate elements declared by source code or imported from an assembly as metadata.

A semantic kernel reference can also help follow the principles of semantic versioning, which is a convention for assigning version numbers to packages based on their compatibility and functionality. A central semantic reference can also be used to classify nouns based on their semantic characteristics, such as shape, size, location, or deixis.

Semantic keywords

Semantic keywords are words that have important semantic meanings in sentences and are shared by all good translations of a source text.

Semantic keywords can be identified by using a linguistic framework such as UCCA, which captures the semantic structure of sentences. Semantic keywords can be useful for machine translation evaluation as they reflect the preservation of meaning in all languages. They can also be useful for vocabulary instruction, as they represent the central meaning of a text or topic.


Semantic core features are the essential elements of a text that convey its meaning and purpose. They include the main topic, keywords, main ideas, and supporting details. The characteristics of the semantic core help readers understand and analyze a text, as well as compare and contrast it with other texts. Basic semantic functions also help writers organize and structure their texts, as well as choose the right language and style. Semantic core features can be identified by using various strategies, such as:

– Skimming and scanning the text to get an overview of its content and design.

– Reading the title, epigraphs, subtitles, captions and summaries to identify the main topic and keywords.

– Reading the introduction and conclusion to identify the main ideas and perspective of the author.

– Reading the body paragraphs to identify supporting details and examples that illustrate and explain the main ideas.

– Highlight or underline key words and phrases that relate to the main topic and main ideas.

– Making notes or summaries of the main points and details of each paragraph or section.

– Use graphic organizers, such as graphs, tables, diagrams, or maps, to visually represent the core semantic features of text.
