Messenger++ is a multi-protocol instant messaging client for Android. It features multi-protocol support (currently: XMPP, Facebook(XMPP), Google Talk(XMPP), VK, SMS) + audio calls if supported by the protocol. The UI is optimized for tablets. It is a Maven-based project with Robolectric tests built by Travis CI.
Vibur DBCP is a new, concurrent JDBC connection pool based on Java dynamic proxies. It is fast, has concise source code, and supports a fairness parameter, statement caching, SQL query logging, and many other features. Various configuration examples (with Spring, Hibernate, etc.) are provided.
WebAnno is a general purpose Web-based annotation tool for a wide range of linguistic annotations. It offers annotation project management, freely configurable tagsets, and the management of users in different roles. It uses technology from the brat rapid annotation tool for visualizing and editing annotations in a Web browser. It supports annotation and visualization of arbitrarily large documents, pluggable import/export filters, the curation of annotations across various users, and farming out annotations to a crowdsourcing platform.
JWKTL (Java-based Wiktionary Library) is an application programming interface for the free multilingual online dictionary Wiktionary. Wiktionary is collaboratively constructed by volunteers and continually growing. JWKTL enables efficient and structured access to the information encoded in the English, German, and Russian Wiktionary language editions, including sense definitions, part of speech tags, etymology, example sentences, translations, semantic relations, and many other lexical information types.
DKPro Lab is a lightweight framework for parameter sweeping experiments. It allows the user to set up experiments consisting of multiple interdependent tasks in a declarative manner with minimal overhead. Parameters are injected into tasks using via annotated class fields. Data produced by a task for any particular parameter configuration is stored and re-used whenever possible to avoid needless recalculation of results. Reports can be attached to each task to post-process the experimental results and present them in a convenient manner (e.g., as tables or charts).
Pixy is a declarative graph query language that works on any Blueprints-compatible graph database. The Blueprints API provides a common interface to over a dozen graph databases, including Neo4J, Titan, Infinite Graph, OrientDB, DEX, and Bitsy. Pixy enables complex pattern matching and logic programming on graph databases by translating PROLOG-style rules and goals to Gremlin pipelines that represent graph traversal operations. Queries in Pixy can also be seemlessly integrated into Gremlin expressions. The combination of Pixy and Gremlin gives the programmer the full power of two graph querying paradigms, viz. graph pattern matching and graph traversal.
