Text Classification Criteria

Texts can be classified according to various criteria. From a communication perspective, they can be categorized by their predominant social function, the author's purpose, the medium used for transmission, the subject matter or content organization, the linguistic resources employed, and more.

Communicative Intent and Text Types

Texts are often categorized by their primary communicative intention:

• Informational Texts: Aim to transmit new information, helping the receiver learn new concepts and establish new relationships between existing concepts.
• Persuasive Texts: Seek to change the ideas, opinions, or values of the receiver.
• Management Texts: Attempt to regulate the behavior of recipients.
• Literary Texts: Have an aesthetic

Expressing Opinions & Communication Forms

Expressions of opinion involve explaining one's own ideas about a topic, informing the recipient about them.

• In bilateral communications (conversations, discussions), oral language is used.
• In unilateral communication (books, articles, etc.), written language and a specific linguistic form are used.
• Blogs are bilateral forms of communication used in a colloquial register.

Punctuation for Clarity

Using Quotation Marks

• To enclose quotations of any length.
• To indicate words from other languages that are not adapted to Castilian Spanish.
• To highlight words or expressions that are inappropriate, vulgar, or used ironically.
• To list the title of an article, a song, etc.

Using Parentheses

• To add clarification within

The Role of Language: Functions and Purposes

Language serves various purposes in communication. Understanding these functions helps us analyze how messages are constructed and interpreted.

Referential or Representative Function

This function focuses on the context or referent, aiming to convey information about external reality. Its characteristic feature is objectivity. While it may seem to lack the rich linguistic resources found in other functions, its key characteristics include:

• The indicative mood
• Lack of adjectives that involve value judgments
• Neutral and denotative vocabulary
• Neutral intonation

Expressive or Emotive Function

This function is oriented towards the emitter. The message emphasizes the speaker's attitude towards facts, feelings,... Continue reading "Understanding Language Functions and Social Varieties" »

Understanding Prescriptive Language

Prescriptive language is a type of discourse that aims to guide or regulate the behavior of the recipient in the development of an activity or task.

Types of Prescriptive Texts

• Regulatory Texts: These collect orders or rules by which the issuer intends to govern behavior. Examples include laws, regulations, and codes of conduct.
• Instructional Texts: These provide tips or instructions for the receiver to perform a task. Examples include recipes, manuals, and how-to guides.

Structure of Prescriptive Language

The structure of prescriptive language typically includes:

• Goal

  This serves as the title and sometimes includes an initial explanation in the first paragraph, outlining the objective of the prescriptive text.

• Program

  This

Instructional Texts: Guiding Future Actions

Instructional texts aim to teach the receiver how to regulate their conduct in the future, effectively directing, teaching, arranging, or advising them on performing actions.

Structure of Instructional Texts

• Objective: The purpose of the text, often brief and summarized in the title.
• Instructions: Steps presented in a logical (cause-effect) or chronological order, detailing orders, advice, or actions. Ideas are typically organized into paragraphs, each addressing a single topic or subtopic. Instructions may also be grouped into sections or subsections.

Linguistic Characteristics of Instructional Texts

• Verbal Forms: Frequent use of conative verbal forms or appeals (e.g., must do, has to do).
• Person: Use of

Scientific and Journalistic Texts: A Comparison

Scientific Texts

Scientific texts encompass research reports, studies, and scientific expertise. The primary objectives are to present accurate, clear, and demonstrable statements of fact.

General Characteristics:

• Clear and logical management of information
• Objectivity
• True and verifiable conclusions
• Brief paragraphs
• Support from graphics and artificial languages

Linguistic Features:

• Denotative lexicon
• Monosemic words
• Use of jargon
• Concrete nouns
• Use of the present indicative tense
• Specified adjectives
• Reflexive passives
• Impersonal sentences
• Declarative sentences

Structure:

Scientific texts employ exposition and description. Exposition explains and clarifies concepts, while description presents the characteristics... Continue reading "Understanding Scientific and Journalistic Texts: Key Features" »

Adjectival Subordinate Clauses

Adjectival subordinate clauses are propositions whose function is equivalent to that of adjectives in simple sentences, usually serving as a nominal complement to which they refer.

Types of Adjectival Clauses

• Specify: These form a single phonetic group with the noun they relate to and limit its field of application.
• Explanatory: Framed between two pauses, these express a characteristic or provide clarification.

Key Characteristics of Adjectival Clauses

1. The relative pronoun "which" can be confused with the conjunction "that". To distinguish them, try replacing "which" with "that" (or vice versa). If the change is grammatically acceptable, it is likely a subordinate adjective clause.
2. An adjectival clause almost always

Elements of Communication

The elements involved in an act of communication are:

• Sender: Produces the message and sends it.
• Receiver: Receives the message and interprets it.
• Code: A set of signs and rules that the sender and the receiver know and use to encode and decode the message.
• Message: The statement sent by the sender and received by the receiver.

• Context: The circumstances (psychological, social, emotional, etc.) surrounding the sender and receiver, which influence the message's transmission and reception.
• Referent: The real-world element or situation to which the sender's message refers.
• Noise: Any interference affecting any of the other elements, which causes the

Channel Signaling: Types and Performance

Channel-Associated Signaling

Channel-associated signaling transmits signals needed to manage and control a particular channel conversation along with the channel itself. Traditionally, the signals corresponding to a circuit are transmitted by the circuit itself.

Common Channel Signaling

The introduction of stored program control (SPC) leads to a novel method of marking. The control unit can send signaling channel signals for all circuits which are in conversation on a particular route. This method is called common channel signaling.

Signaling System Performance

When establishing a signaling system, it's necessary to determine the role the intermediate centrals will play in the performance of their control... Continue reading "Channel Signaling: Types, Performance & System Establishment" »
