Isobel is a framework to build complex information retrieval and analysis systems. Isobel can be functionally divided in two subsytems, Isobel Gatherer (the crawling and filtering subsystem) and Isobel Analyzer (the analysis subsystem). The two subsytems can also be used separately. Isobel Gatherer offers ready-to-use services like content fetching, scheduling, document format conversion, Hyperlink graph storage and analysis, content storage and indexing. A programmer may easily add new services. Isobel Analyzer uses the IBM UIMA architecture to reuse the analysis components developed for this architecture.
MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition, along with sample applications (identification, NLP, etc.) of its use. MARF can run distributed over the network (CORBA, Java RMI, and Java XML-RPC Web Services) and may act as a library in applications or be used as a source for learning and extension.
GPalta is a genetic programming toolbox that aims for simplicity and speed. It features tree-based genetic programming, optional strong typing, a multithreaded GUI to control an evolution process, the ability to save evolutions to a file, to be continued at another time and place, and easy interoperability with Matlab.
YProlog is a pocket Prolog engine written in 100% Java. It provides a number of fast and easy Java-Prolog interfacing functions that enables the Prolog database to be used like an SQL-type database. It has fast consult and retract operations, can "serialize" database contents into text, and can easily load and store tables or contents of Java objects. It is based on Jean Vaucher's XProlog.
SENTENSA Knowledge Miner is a platform independent tool for searching any text. SENTENSA uses robust methods of indexing and searching text, leveraging experience from more than 20 years of information retrieval. SENTENSA products offer advanced text retrieval solutions for large databases that will make your searches for key information fast and effective. You can index on one platform and query on another.
EvoJava is a program for interactively exploring intriguing concepts in computer science. From cellular automata and rule-based systems to fractals and genetic algorithms, EvoJava is an education tool for anyone interested in the "edges" of science. Or, if nothing else, it makes a lot of pretty pictures.
The RL-Glue is intended to provide a foundation for building benchmarks for reinforcement learning (RL) agents. A secondary goal is to support RL competitions in which agents are compared in their performance on new problems that are only revealed at the time of a competition. The current version of the interface software supports direct function call communication between agents and environments written in C. The interface software also provides a standard mechanism for communication between agents and environments written in different programming languages.
SIOX4Java (Simple Interactive Object Extraction) is a Java SDK that provides a generic segmentation engine for extracting the foreground from still images with little user interaction. The underlying method (which has also been integrated into GIMP) is noise and motion blur robust and can easily be adapted for the segmentation of objects in videos. The SDK also contains an experimental feature called the "Detail Refinement Brush", which enables the removal of spill colors and manual refinement of highly detailed textures.
