Tools

The Tetherless World Constellation collection of tools and methods contributes to a complete semantic ecosystem supporting data lifecycle components including dissemination, transformation, management, investigation, and visualization. 

Whyis is a nano-scale knowledge graph publishing, management, and analysis framework. It supports domain-aware management and curation of knowledge from many different sources. It's used to create useful domain- and data-driven knowledge graphs. 

EO is a general-purpose semantic representation for explanations considering dependencies from system-, user- and interface- spaces. 
We have open-sourced the ontology and shown use in seven exemplar use cases spanning food, finance and healthcare.

API for handling HAScO-based knowledge graphs. HASCO is an ontology describing how instruments are used to acquire and collect data in support of scientific studies.

Infrastructure that enables combined acquisitions of data and metadata in a way that metadata is properly and logically connected to data.

The Semantic Data Dictionary (SDD) allows for the creation of semantic annotations for columns in a data set, categorical or coded cell values, and intrinsic concepts implicit in the data.

The SDD-Gen is an ontological-level alignment algorithm that aligns tabular data to ontological terms for knowledge graph generation. It leverages context information from data dictionaries to generate suggestions for tabular alignments using semantic data dictionaries.

An approach for converting structured data into RDF

SCO helps in the representation of descriptions of study populations in clinical trials including the various treatment arms, their measured characteristics and descriptive statistics of patients belonging to these arms.

The Diabetes Pharmacology Ontology (DPO) is an ontology designed to support multimodal clinical reasoning for the diagnosis and treatment of diabetes.
