Apache Jena project! Apache Jena™ is a Java framework for building Semantic Web applications. Jena provides a collection of tools and Java libraries to help you to develop semantic web and linked-data apps, tools and servers.
"Jena is a Java framework for building Semantic Web applications. It provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine.

The Sematic Web Client Library represents the complete Semantic Web as a single RDF graph. The library enables applications to query this global graph using SPARQL- and find(SPO) queries. To answer queries, the library dynamically retrieves information from the Semantic Web by dereferencing HTTP URIs, by following rdfs:seeAlso links, and by querying the Sindice search engine. The library is written in Java and is based on the Jena framework.

Wandora is a general purpose information extraction, management, and publishing application based on Topic Maps and Java Swing. Wandora has graphical user interface, layered presentation of knowledge, several data storage options, huge collection of data extraction, import and export options, embedded server, and open plug-in architecture. Wandora is a FOSS application with GNU GPL license.
The LDSpider project provides a web crawling framework for the Linked Data web. Requirements and challenges for crawling the Linked Data web are different from regular web crawling, thus the LDSpider project offers a web crawler adapted to traverse and harvest content from the Linked Data web.

"Skymind is the company behind Deeplearning4j, the only commercial-grade, open-source, distributed deep-learning library written for Java and Scala. Integrated with Hadoop and Spark, DL4J is specifically designed to run in business environments on distributed GPUs and CPUs."
Apache Stanbol (currently in incubation ) is an open source modular software stack and reusable set of components for semantic content management. Apache Stanbol components are meant to be accessed over RESTful interfaces to provide semantic services for content management. The current code is written in Java and based on the OSGi modularization framework. Applications include extending existing content management systems with (internal or external) semantic services, and creating new types of content management systems with semantics at their core.
The Semantic Measures Library (SML) is an open source Java library dedicated to semantic measures computation and analysis.
Tools based on the SML are also provided through the SML-Toolkit, a command line software giving access to some of the functionalities of the library.
This Java Library provides a simple interface for querying the Semantic Web Index Sindice.com. It supports both term queries and advanced queries with the possibility to set different query parameters like : page number, sorting of results by date.

The OWL API is a Java API and reference implmentation for creating, manipulating and serialising OWL Ontologies. The latest version of the API is focused towards OWL 2
Oroboro is a lightweight Java RDF processing framework. Its design focuses on rule-based data extraction and integration tasks involving moderate datasets, targeting common use cases while striving to remain as simple and flexible as possible.
Linking Public Vocabularies
We are happy to present Open Vocabulary, one of open source projects hosted by Knowledge Hives, which delivers Java API and REST API for managing knowledge organization systems. Since version 2.0 of OpenVocabulary, we also support Python Django API to access our vocabularies.
The LDSpider project aims to build a web crawling framework for the linked data web. Requirements and challenges for crawling the linked data web are different from regular web crawling, thus this projects offer a web crawler adapted to traverse and harvest sources and instances from the linked data web. We offer a single jar which can be easily integrated into own applications.
