• It is now possible to use workspace operations directly on the command-line, without the "operate" operation.
• Replaced the OCaml tokenizer and Carafe tagger with the Java reimplementation. This necessitates a number of changes, including retokenizing your documents and rebuilding your models (see the upgrade notes).
• Command-line options for steps which are used in more than one step are now appropriately cross-referenced in the help string.
• Workspace operations which don't affect any pathnames now raise an error.
• The system now appears to work in Python 2.6 and in MacOS X 10.6.
• The experiment engine XML file now allows you to define bindings for commonly repeated values, and also supports explicitly referring to the experiment directory and pattern directory.
• The system now works in native Windows, without Cygwin.
• The system is now distributed in a single zip file for all platforms.
• The MAT UI has been improved to support hand annotation without tokens (although this is not recommended).
  
• MacOS X no longer requires a special installation of Python, even though select.poll is still missing on that platform.
• Bug 24205: due to a bug in the experiment engine, non-default model configurations weren't being handled correctly. Fixed.
• Bugs 15815, 19669: Make sure that the whole system does the right thing with spaces in filenames. Fixed.

1.2pre1

• Extended and modified how corpora are specified in experiment XML, introducing considerably greater flexibility. It's now possible to specify n-way corpus splits, and group them arbitrarily in training and test runs.

1.1RC2

• Fixed an obscure bug where child tasks of visible tasks weren't being reported appropriately to the UI.
• Fixed a minor bug in formatting XML output.
• Fixed a bug in workspace locking.
• Minor documentation updates.
  

1.1RC1

• Enabled confidence interval reporting. Added reporting of standard deviation.
  
• Added general workspace locking for operations, importing and removing basenames, opening a workspace file in the UI, and listing the contents of the workspace folders.
  
• Initial support for Python 2.6.
• Upgraded to CherryPy 3.1.2.
  
• Added XML reader to MATWorkspaceEngine import; expanded documentation on MATExperimentEngine to describe how to prepare corpora with XML documents.
  
• Added support for multiple model build settings in task.xml.
• Added PluginMgr.AlignStep to the core to support alignment of externally-generated content tags with token boundaries.
• Converted calls to MATEngine command-line tool in the experiment engine to invocations of the MATEngine object.
• Expanded Java service API to cover checking for the existence of a workspace, listing the contents of a workspace folder, and opening a workspace file.
  
• Bug 24020: due to a bug in the demo infrastructure, it was not possible to reprocess a document reliably. Fixed.
• Bug 23988: proxies for multiple steps in task.xml weren't doing the right thing when the proxy set didn't exactly match between proxies. You shouldn't do this, and the UI still exhibits some unusual behavior, but it's fixed in the engine.
• Bug 21112: the experiment engine insisted on converting test documents to raw form before processing for the test run phase. It's now possible to specify other default preprocessing (e.g., just undo tagging).
• Bug 20835: global maintenance of annotation type objects was not thread-safe. Fixed by making annotation type objects local to a document.
  

1.1pre1

• Added XML reader and writer to MATEngine, MATModelBuilder, MATScore, UI.
  
• Added ability to define arbitrary readers and writers.
• Added the ability to use your own training engine in your own task.
  
• Added feedback for workspace import.
• Added option to enable workspace access from remote clients via the Web server.
• Added splash screen to UI.
• Enhanced scorer to provide file-level count data to support computing confidence intervals (not enabled yet).
• Enhanced load and save in workspace mode in UI by adding the document basename to the Web service result.
• Added the "rich, incoming"  folder to the core workspace, for importing files which are in rich format but not yet prepared for hand tagging.
• Enabled rich document readers to infer the processing state of documents which lack the appropriate metadata.
• Added "remove" operation to MATWorkspaceEngine.
• Fixed a subtle bug where tagging engines which fail on startup were not notifying the UI client properly about the failure.
  

1.0

• Fixed an obscure bug where MAT JSON documents which share the same annotation label but have different attribute orders were being digested inconsistently.
• Fixed a small bug in MATWeb which prevented logs from rotating appropriately.
• Fixed a small bug in the Java library which didn't correspond to the (correct) documentation.
• Bug 18427: in some situations where the UI viewport is small, the menu bar would disappear. Fixed.
• Bug 20757: ENAMEX-style tags and attributes didn't work with Carafe training on JSON documents. Fixed.
• Bug 23672: the MIME type of log spreadsheets was incorrect when saved from the MAT UI, causing Excel to fail to digest the logs properly on Windows. Fixed.
• Bug 23668: "Update workspace key" in the UI was failing to percolate appropriately to "Open workspace...". Fixed.
• Minor documentation updates.
  

1.0RC4

• Fixed a bug where command-line arguments of MATEngine weren't overriding step attributes in the task.xml file. Added appropriate tests.
• Fixed a bug where step attribute defaults weren't being postprocessed appropriately.
• Fixed a bug in the Java bindings where it was possible to create an annotation type with null attributes.
• Fixed an infelicity in the initial README when users first unpack the distribution.
• Minor documentation updates.
  

1.0RC3

• Fixed minor omission in experiment infrastructure.
• Fixed a bug where extra task paths were not being canonicalized when task directories were being computed.
  
• Added a temporary fix, to be backed out in 1.1, to use the Carafe engine for the anonymization task in the core distribution.
• Fixed a bug in branding in the UI.
• Minor documentation updates.

1.0RC2

• Minor documentation updates.

1.0RC1

• Vast tracts of documentation updates.
• Minor modifications of the UI log action names to improve consistency.
• Bug 19970: because of a deep bug in the interaction between Firefox and the UI toolkit when the backend server was down, no feedback was being provided to the user about the failure. Fixed.
• Bug 17989: the experiment engine was saving its raw gold files as ASCII, rather than a Unicode-compatible encoding like UTF-8. Fixed.
  
• Bug 17867: HTML and HTTP escapes were not being inserted appropriately in the routines that generate task-specific documentation. Fixed.
  
• Bug 17778: various operations that could be performed in the UI weren't blocking out rerequests while the operation was being performed. Fixed.
  
• Bug 16039: left click (not swipe) on an annotation while hand annotating selected just that token, not the entire annotation. Fixed.
  
• Extended branding to documentation.
  

1.0pre14

• Yet more documentation updates, including Java client library documentation.
  
• Changed the "inherit_actions" attribute of workspace operations in task.xml to "inherit_operations", for consistency.
  
• Fixed a bug in the plugin manager which was making demo files inaccessible for tasks without Python customizations.
  

1.0pre13

• Even more documentation updates.
• Corrected terminology for the deidentification task.
• Fixed MATWeb so that it preserves its workspace key across restarts.
• Expanded the Java client library to support workspace operations.
• Added branding capability to UI and tasks.
  

1.0pre12

• Vast documentation updates.
• Added a Java client library (not documented yet).
• Bug 19772: install.bat was failing with links in Cygwin installation. Fixed.
  

1.0pre11

• The settings for the Carafe model builder are now specified in the task.xml file, and can be overridden in the experiment XML or in the workspace settings. As part of this change, the "task" attribute to <build_settings> in the experiment XML file is no longer recognized.
• Added the MATModelBuilder tool.
• Added the MATManagePluginDirs tool.
• Expanded the documentation.
  

1.0pre10

• The tabbed terminal is now optional. Build, install and runtime have been appropriately updated.
  

1.0pre9

• The visible name of the rich JSON format in the UI, command line, and all configuration and experiment files has been changed to "mat-json". This change is in support of future additions of other readers and writers for the MAT system.
• The URL with which MAT can be accessed in the Web UI has been changed to 'http://<host>:<port>/MAT/desktop".
• For any task directory ending with basename <name>, you can now access a desktop restricted to that task at "http://<host>:<port>/tasks/<name>/desktop".
• Initial support for user-friendly demos has been introduced. The configuration file for this capability will be documented when the capability matures a little more.
• All XML configuration file layouts are now defined by a simple, user-readable templating system.
• It is now possible to define user-visible workflow steps which consist of sequences of implementations of other steps (e.g., "prep" might implement "zone,tokenize").
• The Web UI is no longer tied as closely to the names of the steps in the MAT engine.
• Tasks now support the option of defining "attribute sets" for annotations, so that, e.g., an ENAMEX tag with different values for the "type" attribute can map to different CSS configurations, and be treated differently in the scorer.
• Bug 19240: if a core task was installed using MATInstallApplication after a dependent task, and both had documentation, the documentation rendering was broken. This has been fixed by moving to live, on-line generation of the customized documentation.
  
• Bugs 14466, 16090: The tarball distribution contained multiple copies of the MAT executables, only one of which was configured correctly. All duplications have now been eliminated. As a result, all MAT executables in the tarball distribution should be accessed from src/MAT instead of build/MAT.
• Bugs 14507, 19391: Previously, there was a separate step to install the Web documents in a separate location. That step has now been eliminated.
  

1.0pre8

• MATServer has been removed from the system, and replaced by a thread in the CherryPy Web application.
• The underlying version of Carafe has been upgraded, and old training models are not forward-compatible with the new engine. Models will have to be rebuilt.
  
• Bug 14508: The Web server could not be limited to localhost. Now it can be.
  

1.0pre7

• Apache has been removed from the system, and replaced by the Python-based CherryPy Web application infrastructure.
  

1.0pre6

• The MAT scoring engine now defaults to writing CSV files with spreadsheet-interpretable equations for computed values. This behavior can be controlled on the command line for both the scorer and the experiment engine.
  

1.0pre5

• Conversion of ad-hoc mechanisms for Carafe customization to consistent command-line updates. Note: due to this change, the way to add a permanent Carafe model to a task file has changed.
  
• Bug 16450: the -prior-adjst argument of Carafe was not available for customization in any useful way, even though it controls recall/precision bias. Fixed.
  
• Bug 16225: the random zoning option to optimize PSA training was available only to resynthesized documents, because it was part of the de-identification task. It is now a feature of the trainer itself, and the zone tags are temporarily inserted into the document immediately before training if PSA training is requested.

1.0pre4

• Major refactor of internal management of steps to support step rollback in the backend and address a large number of bugs.
• Bug 18960: switching between workflows wasn't undoing all the appropriate UI configuration steps. Fixed.
  
• Bug 18898: After cleaning up the way transformation and nomination should work in the de-identification task, changing the replacer between the two steps could screw up the application of the transformation. Fixed by cleaning up the way metadata is handled in the UI and transported to the backend.
• Bug 18849: experiment directory is created incorrectly if it doesn't exist when the experiment is started. Fixed.
  
• Bug 18848: Transforming a document in the de-identification task would strip all the tags if tokenization had been skipped. Fixed by doing a smarter job of figuring out how to postprocess transformed documents.
• Bug 18534: hand annotations were not showing up when hand annotated documents were reloaded, because of a logic error in the relationship between steps done and steps visible. Fixed.
• Bug 18430: hand annotation was erroneously available during resynthesis. No longer.
• Bug 18426: the clean step can't be undone, but nothing was preventing this. Now raises an error.
  
• Bug 18425: the clean step was not a core step. It is now.
• Bug 17680: the psaTransform step was not being rolled back appropriately in one implementation of the de-identification task, because it wasn't "really" a transform step. Refactoring the step management fixed this.
• Bug 17610: rollback was not supported in the backend engine. Fixed. Engine now accepts an --undo_through argument.
  
• Bug 16603, 16604: newlines are preserved during transformation in the de-identification task, but the extent of the tags needed to be adjusted. In non-clear replacement, the right thing was happening by accident, because those documents were being tokenized when they shouldn't have been. These documents are now (properly) not tokenized, and the extent adjustment is now done correctly.
• Bug 14512: if there's only a single task or a single workflow, they should not need to be provided. Fixed.
  

1.0pre2

• Major new capability to manage workspaces of documents, including support for iterative model creation.
  
• New "Save/Hide" menu to allow better UI desktop management, as well as a hide widget in the window panes.
• Bug 17687: the UI was showing steps which weren't in the current workflow, because they were in the document. Fixed.
  
• Bug 16747: New windows appear directly on top of each other in the new UI. This has been fixed.
  

0.9p4

• Bug 18457: a number of closely related bugs in the de-identification task conspired to cause document-level cacheing of names and name components to fail.
  

0.9p1

• Added Windows batch scripts to run the various MAT tools outside of the MAT controller.
  

0.9

• A tiny bug fix to address a problem managing absent Carafe models in tasks in delivered tarballs.
  

0.9pre13

• Made entire system Unicode-aware. Added guard to ensure that Carafe does not currently see non-ASCII-compatible files. Added option to pass character encodings to the engine in the UI and on the command line.
  
• Improved error reporting in MATEngine.
  

0.9pre12

• Upgraded to Yahoo UI Toolkit version 2.6.0.
• Added ability to customize scorer to some degree for various tasks.
• Added --debug flag to experiment engine for debugging support.
• Fixed an unreported bug where rerunning the experiment engine to regenerate scores when source_corpus_dir was present was failing.
  
• Bug 17863: errors in the command line tool weren't reporting the file that caused the error for tokenization. Fixing this in all cases isn't really possible at the moment, because of the way batch processing works, but it's possible in non-batch, and should be now fixed.
• Corrected a subtle error in rich document encoding in Python where the sequence "\/" wasn't getting decoded correctly by the python-cjson library. Migrated to simplejson.
• In the de-identification task, added a simple Java client example for the MAT CGI script.

0.9pre11

• Enabled chains of source corpora dependencies in experiment engine. This corrected an error where the engine would fail if a corpus pointed to a source corpus which itself pointed to a source corpus. The only visible consequence of this change is that <prep> instructions in these chains are layered; if a corpus has a <prep> instruction and a source_corpus_dir attribute, the input to the <prep> instruction will be the output of any <prep> instructions in the source corpus, rather than ignoring the <prep> instruction in the source corpus as the system previously did. We know of no system deployments which exploited this previous configuration.
  
• Bug 17681: the psaTransform step was being recorded by mistake in the transformed document in the de-identification task. The system now imposes a more general requirement that steps are only recorded on documents modified by side effect, rather than freshly produced documents.
• Added the ability to pass a lexicon to the training engine.
• Added the ability to pass an experiment directory to the experiment engine.
• Relaxed the requirement that the source_corpus_dir attribute in the experiment configuration be an absolute pathname. Now, like other paths in the experiment configuration, if it is not absolute, the experiment directory will be prepended.
• The experiment engine now copies the experiment XML file into the experiment directory, if a file by that name is not already present.
  

0.9pre10

• Bug 17613: in the de-identification task, a small bug in the training engine was causing the training to fail if annotations already contained a replacement nomination. Fixed.
  
• Bug 17612: a repeat of bug 16099, where trailing newlines aligned tokens with tags incorrectly after replacement. The previous fix was slightly incorrect. Fixed.
  
• Fixed an element of inflexibility in the Carafe trainer, which didn't permit the command line in the <prep> experiment XML tag to support input documents which were rich documents. This command line no longer supplies the --input_file_type argument automatically, and it must now be provided explicitly in the experiment XML file.
• Added the beginnings of an improved test suite (not yet documented).
  

0.9pre9

• Bug 16095: Carafe trainer couldn't handle empty lines in the file specifying the available tags. Fixed in the experiment engine by automatically generating the tag file. As a result, the --task arguments are no longer supported in the <prep> and <run_settings> command lines in the experiment XML; the toplevel <experiment> tag now requires a "task" attribute; and the <build_settings> tag no longer accepts the "tag_set" attribute.
• Bug 16749: deleting a document window while the document was being tagged caused a Javascript error. Fixed.
• Bug 17027: in the UI, it was possible to include trailing or leading whitespace in an annotation during hand tagging. Fixed.
• Bug 17028: in the UI, it was possible to swipe from a taggable point across an untaggable point to another taggable point. This now generates an error to the user.
• Bug 17029: bug 16096 was not completely fixed in 0.9pre6; trying to repeat some errorful calls caused the system to hang. Fixed.
  

0.9pre8

• Fixed minor score accumulation bugs in experiment engine.
  

0.9pre7

• Fixed bug where distributions with only a single task defined caused an error in the UI.
  

0.9pre6

• Cleaned up computation of file save paths so the application never adds more than one pathname suffix.
  
• Bug 14509: to simplify task descriptions, display configuration, Javascript, and CSS files should be automatically inherited from their parent tasks. Fixed.
• Bug 14393: modification check was not performed when the task changed. This bug was mostly applicable to the old interface, but in the new interface, all client changes are tracked, and rollback confirmation is presented when any change is undone, or when document is closed. Fixed.
• Bug 15856: modification check was not performed when steps were undone. Same issue as bug 14393 above. Fixed.
• Bug 16096: various Carafe errors were not being percolated back to the client appropriately. Fixed many, many tiny bugs.
  

0.9pre5

• Added functionality to support customization of core documentation to allow incorporation of application-specific documentation and application-specific branding.
• Bug 14650: mat_controller.sh was starting up even if the ports that its servers needed were taken. Fixed.
  

0.9pre4

• Experiment engine now does the right thing when corpora are reused and modified in the consuming experiment.
  

0.9pre3

• Bug 16099: bracket redaction spans were mistakenly expanded over subsequent tokens in some cases. Fixed.
• Bug 16478: zone step in interface was not rolled back correctly. Fixed.
• Bug 16098: drop-down menus were obscured by document windows. Partially fixed; menu bar can still be partially obscured.
  

0.9pre2

• Feature request 16097: Added token-level scoring, better alignment for error detail to the scoring engine.
  
• Bug 16255: the experiment engine should switch to noninterleaved mode when it detects that some models have already been built. Fixed.
• Bug 16256: documentation for training_increment in experiment XML documentation was incomplete. Fixed.
  

0.9pre1

• New user interface, based on the Yahoo! UI toolkit, featuring a desktop-style interaction with a top menubar and multiple moveable, resizeable document panes.
• Bug 15870: annotation popups in Firefox 3 were popping up in the lower left corner. Fixed in the new UI.
  

0.8RC6

• Expanded UI log facility to record seconds since log start, more details about UI annotation popup interaction.

0.8RC5

• Feature request 15803: Initial support for keyboard accelerators in UI annotation popup.
  
• Bug 15826: the UI was mistakenly recording some steps that it shouldn't be recording. Fixed.
• Bug 15810: steps in the UI were not changing when the user changed the workflow. Fixed.
• Bug 15809: hand annotation was available before zoning was applied. In the current system, this could result in undigestible data. Fixed.
• Bug 15808: the "Save raw" button for raw documents made no sense, and was misleading. Now disabled.
• Bug 15806: tag names were not alphabetized in the annotation popup. Fixed.
• Bug 15807: some annotation names should be white foreground text. Easily supported through task specification; tasks updated.
• Bug 15814: annotations weren't visible when reloading saved rich documents. This bug revealed a number of issues with handling the global order of steps across workflows, which have hopefully all been addressed.
• Bug 14394: steps update wasn't working when workflow changed. Fixed.
• Bug 15815: Unix installation path cannot contain spaces. Temporarily fixed by aborting installation, with warning, if spaces are in the path.
