Background

KBpedia exploits large-scale knowledge bases and semantic technologies for effective machine learning and data interoperability. KBpedia can power knowledge management-oriented Web services and APIs. KBpedia is a re-factoring of public knowledge bases — Wikipedia, Wikidata, schema.org, DBpedia, GeoNames, OpenCyc, and the UNSPSC products and services — into an integrated whole. This logically coherent knowledge structure makes the entire system computable. The combined knowledge sources within KBpedia provide rich and unparalleled feature sets upon which to train machine learners and conduct artificial intelligence. KBpedia thus provides unique capabilities in:

• A computable overlay for either Wikipedia or Wikidata
• Integrating domain data
• Fine-grained entity identification, extraction and tagging
• Faceted, semantic search and retrieval
• Mapping and integration of external datasets
• Natural language processing and computational linguistics
• Knowledge graph creation, extension and maintenance
• Tailored filtering, slicing-and-dicing, and extraction of domain knowledge structures
• Data harvesting, transformation and ingest
• A fast and clean source for word embedding models
• A coherent framework for graph embedding models
• Data interoperability, re-use of existing content and data assets, and knowledge discovery
• Supervised, semi-supervised and distant supervised machine learning for:
• Typing, classification, extraction, and tagging of entities, attributes and relations
• Unsupervised and deep learning.
