Symbolab is a semantic web search engine for math and science. It allows users to search for equations, formulas and expressions using mathematical symbols and scientific notations as well as full text search. The stated goal of the site is to provide the most relevant search results that are theoretically and semantically similar, rather than visually.

"The purpose of this website is to provide a secure, permanent URL re-direction service for Web applications. This service is run by the W3C Permanent Identifier Community Group."

"The MultilingualWeb initiative is concerned with standards and best practices that support the creation, localization and use of multilingual web-based information. Through W3C workshops open to the public and various communication channels, it spreads information about what standards and best practices currently exist, and what gaps need to be filled."

"The Apache Mahout™ machine learning library's goal is to build scalable machine learning libraries."

The Apache OpenNLP library is a machine learning based toolkit for the processing of natural language text.

"The Open Relevance Project (ORP) is a small Apache LuceneTM sub-project aimed at making materials for doing relevance testing for Information Retrieval (IR), Machine Learning and Natural Language Processing (NLP) into open source."

'.. our Semantic Web Portal technology will be a community portal for the Semantic Web community, at semanticweb.org. We aim to bring together research groups, research projects, software developers and user communities in the Semantic Web area.'

Use gruff to display visual graphs of subsets of a store's resources and their links. By selecting particular resources and predicates, you can build a visual graph that displays a variety of the relationships in a triple-store. Gruff can also display tables of all properties of selected resources or generate tables with SPARQL queries, and resources in the tables can be added to the visual graph.

OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.
