Semantica 🧠 • Build AI systems that can explain, trace, and justify every decision. Knowledge graphs, context graphs, reasoning engines, provenance, and governance for production AI.

VeritasGraph — open-source Knowledge Graph & GraphRAG framework on GitHub. Build multi-hop reasoning, ontology-aware retrieval, and verifiable attribution over your own data. Nodes, edges, RDF, linked-data — runs locally or in the cloud.

Building and Using Knowledge Graphs made easy

EMelodyGen creates emotional ABC melodies via templates. Rough4Q dataset is auto-labeled by small emotional datasets and music psychology to fine-tune backbone after augmentation with 99% correct rate, 91% emotional alignment and effective feature controls.|EMelodyGen通过模板控制ABC生成旋律情感。利用小型情感数据集和音乐心理学为Rough4Q数据集生成标签，经转换和增强后微调骨干网络。生成谱正确率99%，情感准确率为 91%。

This Repository contains all exercises done (in class and as assignments) during the course Knowledge Engineering and Business Intelligence at UNICAM LM-18 MS Computer Science

Hierarchical agent skills for domain ontology planning, research, construction, and validation with saved research artifacts and eval-ready workflows.

A Python library and CLI to convert SWRL rules between human-readable text and RDF, merge them into OWL ontologies, and extract rules back to text.

Meeting scheduler for groups of people in mobilities at different places. It includes the analysis of flights and lodging prices to return the better date and place for everyone to travel together.

Enterprise AI Business Intelligence platform featuring semantic search, knowledge engine, persistent vector storage, and production-oriented architecture built with FastAPI, FAISS, and Python.

The SSWG/MVM framework is a recursive workflow generator that unites symbolic structure with semantic evaluation. It synthesizes workflows, validates them against schemas, measures clarity and coherence, and iteratively refines results until improvement plateaus. Through memory, metrics, and modular orchestration, it is both software and mindset.
