    • We've reduced the logging verbosity around worker management.

    • Configuration information is now sent to the logs at startup.

  • Improved performance:

    • Event extraction runtime speed and memory usage have been significantly improved for documents containing multiple events.

    • The number of network calls between components due to eureka registrations has been reduced.

  • Improved upgrades: The version information for the Events Training Server has been internalized, allowing most upgrades to consist of re-releasing container images only.

  • Events guidance updates: The documentation now provides guidance for events modeling.

    • For event extraction, you may only need a few hundred training samples. For performance reasons, we recommend a maximum of 1000 training samples. We also recommend a mix of positive and negative samples. A negative sample is one where the key phrase is not an example of an event you'd like to extract. The exact number will depend on how ambiguous the key phrase is; a more ambiguous key phrase will require more negative examples. At the most, 10% of the samples should be negative examples.

    • Input documents for event extraction should be no larger than 4K characters.

Bug Fixes

  • Chinese, Japanese, and Korean are now working correctly for event extraction.

  • The unused sanity_check.sh script has been removed from the release. It was no longer relevant.

  • Spurious errors no longer appear in Adaptation Studio logs.

  • Events Training Server no longer has occasional NullPointerException during worker registration.

  • The debug log for Events Training Server now contains object descriptions instead of object addresses.

Upgrade Instructions

Use the following instructions to upgrade from release 0.9.5 to 0.9.5.1.

  1. Load the new Rosette Server image. On each machine running Rosette Server, run:

    docker load < rosette-server-enterprise-cp-1.20.3.tar.gz

  2. Edit the Rosette Server configuration. On each machine running Rosette Server, perform the following steps:

    1. Edit the file <install_dir>/rs/rs-docker/.env, updating the value of ROSETTE_SERVER_IMAGE:

      # Rosette Server information
ROSETTE_SERVER_IMAGE=rosette/server-enterprise-cp:1.20.3

    2. Edit the file <install_dir>/rs/config/com.basistech.ws.transport.embedded.cfg, setting the value of workerThreadCount to 4. This will improve system performance:

      # workerThreadCount is the number of threads that are created to do the actual work
# in the embedded local transport, for worker residing in the same machine. Default is 2.                                                            
# It is probably best to not go above 2-3x the number of physical cores on the host machine.                                                         
workerThreadCount=4    

    3. Restart the server. From the <install_dir>/rs/rs-docker directory:

      docker-compose down
docker-compose up

  3. Load the new ETS images. On each machine running ETS, run:

    docker load < python-events-training-server-v0.8.8.tar.gz 
docker load < events-training-server-0.0.26.1.tar.gz 

  4. Edit the ETS configuration. On each machine running ETS, perform the following steps:

    1. Edit the file <install_dir>/ets/ets-docker/.env, updating the values of ETS_IMAGE and and PETS_IMAGE:

      ETS_IMAGE=events-training-server:0.0.26.1
PETS_IMAGE=python-events-training-server:v0.8.8

    2. Edit the file <install_dir>/ets/config/application.yml to remove the version and build properites from the info.app section. The version information is now contained in the container itself.

      info:
  app:
    name: "Rosette Events Training Server"
    description: "Rosette Event Extraction and Training Server"
    version: "x.y.x"  ← remove this line
    build: "1234"     ← remove this line

    3. To always restart the proxy image, edit the file <install_dir>/ets/ets-docker/docker-compose.yml, adding the line restart: always to the proxy service:

        proxy:
    restart: always

      Note: you must match the indentation of the yml file and use spaces, not tabs.

    4. Restart the server. From the <install_dir>/ets/ets-docker directory:

      docker-compose down
docker-compose up

    5. Verify the new ETS images. In the <install_dir/ets/ets-docker directory, run:

      docker-compose images

      The output should be similar to the following (note the updated tags):

       Container      Repository                      Tag          Image Id       Size
-------------------------------------------------------------------------------------------

Release 0.9.5

December 2021

New

  • SSL support: SSL is supported for all servers.

  • Inference renamed to extraction: Inference mode for events has been renamed to extraction mode for clarity, based on feedback from users.

  • Improved install: The install scripts have been improved, including the addition of installation log files.

  • Improved model upload script: The script to upload an events model for extraction (ets-upload-model.sh) now checks if the model already exists on the server. If it does, the user can choose whether to replace the model.

  • New export model info file: An information file is downloaded along with the model when a model is exported. This is for both event and entity models.

  • Superuser password: We improved the dialogue around setting the RAS superuser password. You are prompted to reset it on the first login.

  • RAS Password security: Setting of passwords is now more secure.

  • Single ETS install file: The same ETS install file (install-ets.sh) supports both the training and extraction modes of ETS. The script prompts the user for the mode (training or extraction).

  • IAA: Inter-Annotator Agreement (IAA) is supported for event annotation.

  • Help: The RAS help file has been updated.

  • Versions included in this release:

    • Rosette Server: 1.20.0

    • REX Training Server: 1.0.1

  • ETS no longer runs out of memory with large extraction documents.

  • Numerous enhancements and bug fixes have been completed.

Known Issues

  • Adjudication is not supported for event annotation.

  • Event models from previous releases cannot be opened in this release. Contact Support for assistance if you have old schema or events models you would like to convert.

  • The headless install capability of ETS, RTS, RS, and RAS is not yet supported.

  • The RAS healthcheck script reports a false error message of unknown container on network.

  • When a sample contains multiple event mentions, the order of the mentions in the sample may impact which samples are extracted.

Release 0.9.4

November 2021

New

  • Multiple event models in a single call: The /events endpoint in Rosette Server supports event extraction from a single model, multiple specified models, or all loaded models. This is documented in section 7.3 of the System Adminstrator Guide.

  • Custom profile schema support: When creating an events schema template, a custom profile can be selected. This allows a project schema based on the template to use custom entity extractors.

  • Events metrics: The Project dashboard now displays event metrics (precision, recall, and F1) for events projects.

  • Documentation enhanced and reorganized: The Model Training Suite documentation set now consists of 3 documents:

    • Adaptation Studio User Guide

      A guide for the managers and annotators using Rosette Adaptation Studio describing how to use the tool to create and maintain projects, annotate and train entity and event extraction models, and create event schemas.

    • Developing Models

      A guide for the system architects and model administrators to aid in defining the modeling strategy and understanding the theory of model training. It includes an explanation of event modeling and how to design an event schema in preparation for training event extraction models, as well as guidelines for gathering and preparing data for model training.

    • System Administrator Guide

      A guide for installing and maintaining both the training and production environments of the Rosette Model Training Suite. Included are instructions for moving trained models from the training environment into the production environment, as well as the documentation for the API calls for entity and event extraction. This includes the content previously in the Deploying models guide.

Known Issues

  • Event models from previous releases cannot be opened in this release. Contact Support for assistance if you have old schema or events models you would like to convert.

  • Samples of 6 words or less will not return role mentions from entity extractors.

  • In this release, tentative role extractors are created as morphological extractors. In the next release, they will be exact transactors. Tentative extractors created for key phrases will remain morphological.

  • In this release, exact transactors do not support multiple tokens. Multiple tokens will be supported in the next release.

  • Event mentions may be extracted when a required role is missing.

  • Clone project is not currently supported for events projects. To copy an events project, export and import the project.

  • When using the plan option to query multiple event models, all event models are queried, not just the models listed in the plan.

  • When a sample contains multiple event mentions, the order of the mentions in the sample may impact which samples are extracted.

New

  • Naming: Rosette Model Training Suite refers to the complete set of annotation, training, and extraction tools. This includes the following products:

    • Rosette Adaptation Studio

    • REX Training Server

    • Events Training Server

    • Rosette Server

  • Event annotation: Rosette Adaptation Studio now supports annotating event mentions.

  • REX Training Server Modifications and Improvements

    • New URL: The base URL is now rts instead of model.

    • Renamed endpoints: All endpoints that started with /rex (training, annotating, etc.) are now under /workspaces/{workspaceId}. Endpoints that took a workspace ID as part of their POST request or as a request parameter now use the route to specify a workspace.

      • /rts/workspaces/{workspaceId}/train-model replaced /model/rex/train-model

      • /rts/workspaces/{workspaceId}/generate-wordclasses replaced /model/rex/generate-wordclasses

  • The headless install capability of ETS, RTS, RS, and RAS is not yet supported.

Release 0.9.2

November 2020

New

  • SSL enabled: SSL can now be enabled between all servers. Scripts are provided to enable and disable SSL.

  • Upgrade script removed: The upgrade-rs-0.8-0.9.sh script has been removed from the installation package. This script only supported upgrading the Rosette Server release when installing 0.9.0.

  • Rosette Server version: The Rosette Server version is 1.17.5.

Bug Fixes

  • Rosette Server will no longer generate a null pointer exception when the indocCoref processor is disabled and a simple response is requested.

Known Issues

  • The healthcheck scripts cannot check connectivity in SSL-enabled environments since they lack access to the cacert, certificates, and keys. The healthcheck scripts can be run after installation but before enabling SSL.

  • When SSL is initially enabled on Rosette Server, the wrapper.log will print an exception. This exception can be safely ignored and is due to a transport rule containing an http route in an SSL enabled environment.

Release 0.9.1

October 2020

Note

When you reinstall the Rosette Adaptation Studio package, all components are reinstalled. Any customizations you make to configuration files should be saved and reapplied after installation.

New

  • Word classes status: The manage page now includes the training status of word classes. You can export a model before word classes are available.

  • Filter improvements: You can now filter on labels in the View Annotations page.

  • Adjudication counts modified: The Adjudicated field on the Project Dashboard now includes the total samples adjudicated, both manually and auto-adjudicated.

  • Case-insensitive models: You can now build case-insensitive models.

  • Help file: The Help file has been updated to match the User Guide.

  • Restart policy added: The restart policy was added to all services. The default is restart: "no".

  • Installation Improvements: We've changed the following files in the Rosette Adaptation Studio installation.

    • Renamed services adding ras_ prefix (ras_server, ras_proxy) to disambiguate from other services running on the machine.

    • Removed the ./config directory from the deployment; it is no longer used.

    • Improved docker-compose.yml file by removing incorrect comments and unnecessary volume declarations.

    • Installing SSL now comments out non-used port rather than deleting the declaration.

  • Rosette Server version: The Rosette Server version is 1.17.4.

Bug Fixes

  • Export Model now always downloads the model. Previously the model was not always downloaded as expected.

  • Installation script no longer creates unused nginx files.

  • The Rosette Server Entity Extractor no longer modifies the normalized field for mentions that are extracted by a custom processor.

Known Issues

  • To force a model to be trained, for example after word classes are completed you may want to retrain a model, you must annotate a couple of samples. The models are automatically training as you annotate samples.

Usage Note

The ad-suggestions profile deployed with Adaptation Studio is designed for sole use of the Adaptation Studio server. Calling the Rosette Server /entities endpoint using the typical calling conventions and specifying the ad-suggestions profile will have undetermined results. This is because the ad-suggestions profile expects hidden parameters to be passed in the call and for an RTS model to have been trained beforehand. Additionally, the response differs from a typical response from the /entities endpoint.

The ad-suggestions profile can be modified like any other profile to customize the behavior of Adaptation Studio. You'll need to use a separate "testing" profile to test the changes.

  1. Create a new custom profile for testing.

  2. Modify the profile with the customizations (such as gazetteers) you want to implement.

  3. Test the changes with the regular /entities endpoint, specifying the profile.

  4. Once testing is complete, apply the customizations to the ad-suggestions profile.

Refer to Section 10.2 of the Adaptation Studio User Guide for information on how to create a custom profile.

Release 0.9

October 2020

Upgrade Script

Rosette Server does not require a full install when upgrading from 0.8 to 0.9. Only the roots for the additional languages need to be added; there is no change to the rest of the installation.

To upgrade Rosette Server from 0.8 to 0.9:

  1. Stop Rosette Server

  2. Unzip the file rs-installation-0.9.zip

  3. From the directory rs-installation-0.9, run the upgrade script:

    ./upgrade-rs-0.8-0.9.sh

  4. Start Rosette Server

New

  • New languages: Rosette Adaptation Studio now supports Arabic, Chinese, Korean, and Russian in addition to English and Japanese.

  • Use Basis Training data: You now have the option of using the Basis training data to augment the stock model or to build a model from scratch with just the annotations provided by the Studio. Note that you cannot add new entity types when using the Basis training data.

  • UI support for case sensitive and case insensitive models: When creating a new project you now select whether the trained model will be case sensitive or case insensitive. Note: you cannot build case sensitive models in this release.

  • User management improvements: Users can now modify their personal information, including password.

  • Cache management: Dormant models are now automatically ejected from the REX training server memory.

  • Healthcheck scripts: Scripts are now provided to check the health of each of the servers.

  • Status improvements: The Manage page now displays system status, model status, and project status.

  • Online help available: The User Guide is now available from the Adaptation Studio page.

  • New labels: Adding and modifying labels has been improved.

  • Reconcile added: The Finalize task on the project menu has been renamed to Reconcile to more accurately reflect the task performed.

  • Install improvements: Containers are now zipped, so the install is slightly smaller and the containers load about 20% faster.

  • Improved error handling: Error handling has been improved in the Rosette Server and REX Training Server installers.

Bug Fixes

  • Unused labels can now be deleted, even if they were previously in use.

  • All errors that occur while loading documents are now displayed.

  • RTS_URL is now updated in the nginx.conf file after install. The value in the .env file is now used.

Known Issues

  • Case sensitive and case insensitive models: You can only build case sensitive models in this release.

  • Help file: The section Adjudicate in the online Help does not match the section in the User Guide. The User Guide is the latest version.

  • REX Training Server log file messages: The log file for the REX Training Server may contain multiple train-model request failed messages. These are not actual failures. RTS ignores new training requests from a project while there is an active training for that project in process and generates this message. RTS is working as expected.

Release 0.8

September 2020

New Features

  • Japanese is now supported.

  • The newly-trained models can now be used along with the standard REX extractions to select samples and make label predictions.

  • Rosette Adaptation Studio supports extracting entities by mixing the newly trained model with all other REX extractions including the standard REX statistical model, gazetteers, and regexes. Which extractions you use depends on your requirements and is configured through the ad-suggestions custom profile and may require experimentation.

  • Rosette Adaptation Studio now supports model permanence across restarts. If the Rosette Training Server (RTS) crashes at any point in the annotation process, it's able to recover from the crash by reloading the model back into memory from disk.

Known Issues

  • The training data for the new model comes only from the annotations provided by the user and does not currently use the existing REX model training data.

  • We recommend waiting fifteen minutes after the last annotation before downloading the model to ensure all annotations have been incorporated into the training of the model. If not provided sufficient time, the downloaded model may be an earlier version that doesn't include the latest annotations.

Release 0.7

August 2020

  • Supported languages: English.

  • This release of Adaptation Studio trains new models for REX as annotations are completed, but the newly-trained models are not used by the Active Learning to select samples or make label predictions.

  • The Export Model option in the Manage page downloads the newly-trained model. Copy this file into Rosette Server to deploy the new model.

  • The NER-Rosette template is included in this package.
