Semantic Macro Triggering Based on NLP Analysis of Editorial Content

This case study demonstrates how Ascoos OS can execute macros based on semantic analysis of editorial content. It uses NLP techniques to detect sentiment and topic relevance, then triggers macros using a DSL script parsed into an AST structure.

Objective

• Analyze editorial text using `TLanguageProcessingAIHandler`
• Detect sentiment and activated concepts
• Define macro logic using DSL
• Translate DSL into executable macros
• Execute macros when semantic conditions are met

Core Ascoos OS Classes

• TLanguageProcessingAIHandler Performs sentiment analysis and concept activation
• AbstractDslAstBuilder Parses DSL into Abstract Syntax Tree nodes
• AstMacroTranslator Maps AST nodes into macro actions and conditions

File Structure

This case study is implemented in a single PHP file: - semantic_macro_trigger.php

Requirements

1. PHP ? 8.2
2. Installed Ascoos OS or AWES

DSL Example

WHEN sentiment = negative AND topic = "economy" THEN
    TAG "alert"
    NOTIFY "Editor"
    FLAG "Review"

Execution Flow

1. `TLanguageProcessingAIHandler` analyzes the editorial text.
2. Sentiment is extracted using `naiveBayesSentiment()`.
3. Concept activation is performed using `conceptActivationVector()`.
4. DSL is parsed into AST using `AbstractDslAstBuilder`.
5. `AstMacroTranslator` maps DSL nodes to: - `TAG` ? adds semantic tag - `NOTIFY` ? sends notification - `FLAG` ? flags article for review
6. Macros execute only if sentiment is negative and topic is "economy".

Sample Code

$text = "...";
$nlp = new TLanguageProcessingAIHandler();
$sentiment = $nlp->naiveBayesSentiment($text);
$concepts  = $nlp->conceptActivationVector([...], [$text]);

$dsl = <<<DSL
WHEN sentiment = negative AND topic = "economy" THEN
    TAG "alert"
    NOTIFY "Editor"
    FLAG "Review"
DSL;

$astBuilder = new class extends AbstractDslAstBuilder {};
$ast        = $astBuilder->buildAst($dsl);

$translator = new class([...]) extends AstMacroTranslator {};
$macroContainer = $translator->translateAst($ast);
$macroContainer->executeIfTrue();

Expected Output

If sentiment is negative and topic is "economy":

?? Tagged: alert
? Notification sent to: Editor
? Flagged for: Review
