Algorithm

Overview

The Algorithm services provide mathematical and ML-based computation used across the application — primarily by the Assistant chatbot for text similarity scoring.

Available Algorithms

Algorithm	Description
CosineSimilarity	Measures cosine angle between two TF-IDF vectors. Returns 0–1.
JaccardSimilarity	Token set intersection divided by union. Simple overlap measure.
TFIDF	Term Frequency-Inverse Document Frequency vectorizer for text.
EuclidianDistance	Straight-line distance between two vectors.
SectionClassifier	Classifies text into predefined sections using pattern matching.
LineClassifier	Classifies individual lines of text into categories.
Bert	BERT-like semantic similarity (simulated fallback when no external model is connected).
