tricoder 1.2.0

TriVector Code Intelligence - Multi-view code relationship model with advanced semantic embeddings

TriCoder Code Intelligence

TriCoder learns high-quality symbol-level embeddings from codebases using three complementary views:

1. Graph View: Structural relationships via PPMI and SVD
2. Context View: Semantic context via Node2Vec random walks and Word2Vec
3. Typed View: Type information via type-token co-occurrence (optional)

Features

• Subtoken Semantic Graph: Captures fine-grained semantic relationships through subtoken analysis
• File & Module Hierarchy: Leverages file/directory structure for better clustering
• Static Call-Graph Expansion: Propagates call relationships to depth 2-3
• Type Semantic Expansion: Expands composite types into constructors and primitives
• Context Window Co-occurrence: Captures lexical context within ±5 lines
• Improved Negative Sampling: Biased sampling for better temperature calibration
• Hybrid Similarity Scoring: Length-penalized cosine similarity
• Iterative Embedding Smoothing: Diffusion-based smoothing for better clustering
• Query-Time Semantic Expansion: Expands queries with subtokens and types

Installation

Using Poetry (Recommended)

poetry install

Using pip

pip install .

Usage

1. Extract Symbols from Codebase

tricoder-extract --input-dir /path/to/codebase --output-nodes nodes.jsonl --output-edges edges.jsonl --output-types types.jsonl

2. Train Model

tricoder-train --nodes nodes.jsonl --edges edges.jsonl --types types.jsonl --out model_output

3. Query Model

# Single query
tricoder-query --model-dir model_output --symbol sym_0001 --top-k 10

# Interactive mode
tricoder-query --model-dir model_output --interactive
