Gerard de Melo's Projects and Resources
Major Resources and Tools
: One of the largest multilingual knowledge graphs, transforming the well-known
database into a massively multilingual resource covering over 1 million words and several million named entities in a single semantically organized hierarchy. Our derivative project
) is being used by
: Contributes information about words and other language-related entities to the
Linked Data Web
and Semantic Web, leading to a Web of Data in which the
Spanish National Library
, and others have linked their data to Lexvo.org, and Lexvo.org in turn connects its own data to other valuable resources.
: An ontology providing an enormous body of axiomatized world knowledge based on
as well as the
Suggested Upper Merged Ontology (SUMO)
. YAGO was used in IBM's famous Jeopardy!-winning system
: FrameBase uses frame semantics, a theory of natural language semantics, to represent knowledge about the world in a consistent way. I also developed a new
browsing interface for the FrameNet lexical resource
, which FrameBase relies on.
WebChild / Knowlywood
: Large amounts of common-sense knowledge extracted from the Web.
: A database of etymological and derivational relationships between words in different languages, mined from
: Pyramid Evaluation of summary quality using Automated Knowledge extraction — A method for evaluating the quality of a summary (e.g., one written by students) using the Pyramid method, which is known to be significantly more reliable than the ROUGE method when evaluating individual summaries.
: Vector embeddings of words and concepts from the biomedical domain. The source code is a part of
: Lexical resource providing information about Portuguese nominalizations.
Good, Great, Excellent: Semantic Intensity Information
: System that scores the relative intensities of different words.
MASC Word Sense Alignment Visualizations
: Non-1-to-1 alignments of word senses from two inventories visualized. See also our
about this project.
: Thesauri in many languages, obtained by translating Roget's Thesaurus using task-specific statistical techniques
Information Extraction and Information Retrieval
: Source code for a deep neural Information Retrieval system.
Visualizing Multi-Document Semantics via Open Domain Information Extraction
: System that visualizes information from across multiple documents using a graph-based user interface.
Knowledge and Data Resources
Entity Type Description Generator
: Source code for a deep learning-based system that generates natural language descriptions of entities.
Visualizing and Curating Knowledge Graphs over Time and Space
: Video of our temporal knowledge browser (
: Online interface to the SPASS-XDB reasoning system, which combines state-of-the-art theorem proving with support for large-scale knowledge sources
Wikipedia IMDb Mappings
: Mappings between
articles and corresponding
Internet Movie Database
: File Viewer (for DOS) supporting over 400 different file formats.
