Free semantic software for mac

SemREST 0.1 provides you a perfect and useful product which is a free Java framework for the semantic extension of RESTful Web Services. This will be your excellent choice.

Major Features:

1. simplification of data transmission mainly in RDF - but also in other formats (generically requests/responses) for HTTP-operations GET, PUT, POST and DELETE
2. simple bijective mapping of RDF graphs and Java instances
3. simple mapping of RDF graphs on Java interfaces (implying automatic interface implementation)
4. extraction of RDFA data from HTML content (via HTTP GET Request)

Enhancements: First Release.

ANTLRWorks 1.3b brings users a novel grammar development environment for ANTLR v3 grammars, which combines an excellent grammar-aware editor with an interpreter for rapid prototyping and a language-agnostic debugger for isolating grammar errors. ANTLRWorks allows users to edit, visualize, interpret and debug any ANTLR 3 grammar through an easy-to-use graphical user interface.

ANTLRWorks helps eliminate grammar nondeterminisms, one of the most difficult problems for beginners and experts alike, by highlighting nondeterministic paths in the syntax diagram associated with a grammar. ANTLRWorks' goal is to make grammars more accessible to the average programmer, improve maintainability and readability of grammars by providing excellent grammar navigation and refactoring tools, and address the most common questions and problems encountered by grammar developers

Major Features:

1. Editor
   • Single window editing
   • Syntax highlighting
   • Rule navigation tree
   • Jump to rule or token definition
   • Go To Rule
   • Find usages of tokens or rules
   • Find and Replace using regular expression
   • Sensitive keyword, rule, and token auto-completion
   • Rules and actions folding
   • Tips and ideas
   • Auto-indentation
   • Refactoring - remove left recursion, extract or inline rule, etc.
   • Show generated lexer or parser code using syntax coloring
   • Syntax diagram display for lexer and parser rule
   • Show unreachable alternative(s) in syntax diagram
   • Display nondeterminism warning as ambiguous paths through the syntax diagram
   • Highlight decision DFA
   • Rule dependency graph
   • Export syntax diagram, NFA and parse tree to bitmap image or EPS file
   • Perforce integration
   • emacs key bindings (Mac OS X only)
   • Contextual menus
   • Print
2. Grammar interpreter
   • Dynamically interpreter any input text
   • Display parse trees as list or graph
3. Grammar debugger
   • Local or remote debugger
   • Language agnostic
   • Dynamic parse tree
   • Dynamic AST
   • Tree grammar debugging
   • Lookahead highlighting
   • Breakpoint in grammar
   • Breakpoint in input text!
   • Breakpoint on any events - LT, consume token, exception, etc.
   • Step over rule
   • Show corresponding grammar location and parse tree node for each input token
   • Detachable panels
4. Code generation:
   
   • ANTLRWorks supports code generation in any language that ANTLR knows how to generate via the output=language option.
   • For Java, however, ANTLRWorks knows how to build a test harness, compile everything, launch the parser, and connect to it--a great rapid prototyping feature when you can't use the interpreter because actions and/or semantic predicates must execute.

Enhancements:

• New Grammar Wizard
• StringTemplate Editor
• Custom test rig
• Run an input directly on the grammar

Requirements: Java 1.5 or later

Pathway is a very useful semantic browser that tracks your steps through MediaWiki sites such as Wikipedia.
Pathway represents visited pages by nodes, which are interconnected to form the trail that youve made. This enables you to keep a clear overview of your wiki explorations.
Enhancements:
- Support for regular pages :Add and manage any web page.
- New Info inspector, enhanced image viewer: Add notes and file references to any page.
- Search wikis for the articles you want to add: No more encounters with non-existing articles.
- Better searching and filtering: The search function now searches both the contents and titles of articles. Nodes become more visible as they are more important, and visa versa.
- Collections: Collections help you manage pages by dividing them into groups. The new list view makes it easy to drag them where you want them.
Other Enhancements
- Highlighting of nodes on mouse over.
- Arcs now smootly follow the node countour instead of snapping to a fixed point
- Better drag support for the different views.
- Better visual cues for unread status.
- A widescreen view style.
- A refreshed interface style, inspired by Mail.app.
- Ability to empty the cache.
- Friendlier start screen with convenience options.
- Enhanced progress indicator.
- Friendlier loading view.
- Tool tips.
- A Help Book.
- HTTPS support.
- Support for more variations of wiki base URLs.
- Basic undo/redo support.
Bugfixes
- Fixed a bug where Pathway wouldnt save with error: "nodes relationship not satisfied".
- Fixed several cases where Pathway wouldnt show the white cloud around a node.
- And a lot more that I havent kept track of...
Remarks
- This is the English language version only. Localized versions will become available via the "Check updates" button as soon as they are finished.

WordNet.app provides a graphical interface for the WordNet semantic network and is very similar to the X Window System client that is part of the WordNet distribution; except it looks much nicer on Mac OS X! Note that it does not query any of the online versions of WordNet but needs a local copy of the dictionary files.
NOTE: Version 5 will run on Panther only
Enhancements:
- Version 5 is a Mac OS X 10.3 (Panther) update.
- Not only does it fix a major incompatibility on Panther, but also it features a new search field and accompanied features.
- Well, looks nicer now.

VUE 1.5 is developed to be a smart and convenient tool which helps effectively with integrating digital resources into teaching and learning. VUE provides a visual environment for structuring, presenting, and sharing digital information. Using VUE's concept mapping interface, faculty and students design semantic networks of digital resources drawn from digital libraries, local and remote file systems and the Web. The resulting content maps can then be viewed and exchanged online.

Enhancements:

• Include presentation tools
• Support for RDF and integration support for learning management systems (LMS/VLEs) and other educational software environments.
• A new genre of educational software focused on the direct support of exploring, connecting and thinking with digital content.

Computer vision is a subfield of computer science and deals with systems that can make sense of image information.
Building systems suited for high-level computer vision tasks such as object recognition and image classification requires the use of robust image statistics in the form of image features and machine learning algorithms to separate discriminative information from noise.
Tuwo is a C++ library that provides code to extract image features and learn decision functions from training data. Tuwo is suitable for high-level computer vision tasks.
The library should be used freely; in particular, extracting code as you deem necessary is encouraged. Tuwo is not intended to be a single monolithic library. To encourage free use, the library is licensed under the very liberal open-source MIT License.

Main features:
Machine Learning:
- k-means clustering
- nn/soft vector quantization and histograms
- mean shift clustering
- randomized decision tree ensembles
- structured support vector machine training, parallel
- conditional random field, MAP-MRF inference
Image Features:

Input/Output:
- PASCAL VOC challenge XML metafile reader/writer
