Vyasa Layar Release Notes

Support documentation covering updates, bug fixes, and new software features for Vyasa Layar.

Vyasa Layar 2.60.0

September 2022

What’s New

  • Automated Language Detection! Every document indexed with Layar is now run through our language detection model to identify the language used in the text. This prediction is then tagged as an annotation on the document and can also be filtered on using Layar search or through Curate’s metadata filters.
  • PubMed metadata now available as Layar filters. Attributes including publication type, MeSH terms, and IDs such as the DOID and PMID can be used as filterable properties in a Layar search or through Curate’s metadata filters.
  • New Layar Classification Model Available. Users can now leverage the popular fasttext classification model as a base model in their Layar projects. Classify texts into categorical groups with a quick and iterative classification model in Layar or Curate.
  • Text Embedding Service (now available via the API). Transform your texts into vectorized embeddings using our new text embedding service. Use these embeddings as part of your data analytics pipeline to find texts of similar content, style, and more.
  • Table Similarity (now available via the API). Compare two or more tables (or specific columns within two or more tables) to determine the semantic similarity between the tables. This feature utilizes the text embedding service mentioned above.
  • Additional improvements made to the software:
    • Users can now bulk delete projects within Layar
    • Small improvements to the grouping algorithm have been made available in Layar

Vyasa Layar 2.59.0

August 2022

What’s New

  • New Layar Models Available for Molecule Generation:
    • ChemFormer Molecule Generation: generate novel compounds with a transformer model.
    • ChemProp Molecular Property Prediction: predict molecular properties for an input of compounds using a message passing neural network.
    • ChemVector 2.0: a new and improved ChemVector autoencoder model that vectorizes molecular structures and optimizes for specific properties.
  • Render SMILE strings in the browser. Any tables where a SMILE string column is present can be configured to render the compounds directly within the browser.
  • Compound Analytics 3D Plot Visualization! Any compound generation or property prediction model you run in Layar now has a 3D scatterplot to visualize results. You can configure any of the three axes directly within the UI!
  • Tox21 Visualizations are Back! You guys asked for it, we brought it back! The toxicity prediction self-organizing map is back in Layar for any project run with the Tox21 Graph Convolutional Neural Network module!

Vyasa Layar 2.58.0

July 2022

What’s New

  • New Layar Models Available:
    • Text Clustering: In Curate and API
  • Grouping Improvements! Any results generated by our QA models now implement an improved grouping algorithm, which has been applied to all applications where question answering is utilized (Axon, Curate, Layar, Layar API, Signal, and Synapse).
  • VCF files are now supported! If you’re working in genomics, this is a big deal! You can now upload large VCF files and preview the file as a table directly within Layar!
    • Please note that due to the size of these files, users will only be able to view the first 100K rows of these files within the UI. For genomic analyses, please utilize the Layar API to query the full file.
  • Any user can now add additional users. Previously, only administrators could generate the registration link for new users. Now, anyone can create this link and share out.
    • This feature can be changed back to be an admin-only capability. If you wish to change this to admin-only, let us know by reaching out to Vyasa’s Support team.
  • Bulk delete projects in Layar. No more one-by-one deletions. Be careful! You’ll get a warning signal before deletion, but once they’re gone you will not be able to access them again.

Vyasa Layar 2.57.0

June 2022

What’s New

  • New HPE Greenlake Connector! Connect data within your Greenlake cloud storage using our new Layar connector offering.
  • SQL Querying Now Available in Layar Tables. Run real-time SQL queries directly within Layar. Click into tables that originate from your SQL connector, and run a query directly on the table of interest.
  • Clinical Trials Now Captures All Record Changes. Instead of capturing the first record of a clinical trial, we now capture the first record of a registered trial, and also scan for modifications/updates to that record. Any time a record is changed, the document is added as a new file in Layar, and linked back to the original registered trial.
  • New Layar Models Available:
    • Multi-Document Summarization – In addition to our standard summarization models, users can now auto-generate one summary for multiple input documents. For example, if a user is looking to build a single summary of clinical outcomes for the year, based on twelve monthly reports.
    • Tense Conversion – Convert a snippet of text from past to future tense, or vice versa.
  • Jupyter IDE in Layar Has Been Removed. Based on our feedback from users who utilize the API, we’ve decided to remove the embedded Jupyter notebook from Layar. Users can still leverage the Jupyter IDE in their own workspaces, and can utilize the Layar SDK as they had before.

Bug Fixes

  • Minor bugs around ontology tagging in Layar tables have been addressed.
  • Copy/paste with NER highlighted text has been refactored to cleanly copy raw text, without the concept labelling.

Vyasa Layar 2.56.0

May 2022

We’ve been busy this month! Here’s a few of the many updates we’ve made to the software & model collection.

What’s New

  • Vyasa’s Developer Hub is now live for our technical users. This hub provides in depth information about the endpoints, tutorials, support, and more!
  • New Sharepoint Connector Available! Connect data stored within your Sharepoint account using our new Layar connector offering.
  • Concept Details Page in Layar. Any highlighted word or phrase you see in Layar has its own detail page for that specific concept! Learn about its synonyms, which ontologies it exists in, what documents or tables it can be found in, or view any related concepts based on the other data you’ve connected in your data fabric (see featured image above).
  • Buckets of Layar Table Enhancements!
    • Concept Type Prediction & Assignment – If you’ve been interested in tagging your table with specific concept types, we now enable automated concept type prediction. Simply select “Tag Concept Types” for a specific column to start this tagging process. Users can also override these predictions for validation, and to further train the NER models with their suggestions.
    • Ontology Highlighting Now Available – The same ontology highlighting feature available in Layar Documents is now available in Layar Tables! Similarly to how you tag for NER, click the “Tag Concepts”, and select any Layar Ontologies you’d also wish to tag in the modal.
    • Filter tables to view results based on a given column, including keywords, empty/non empty cells, etc.
    • Sort your table based on a specified column.
  • New Layar Models Available:
    • NER Model for Study Endpoint – e.g. overall survival, progression-free survival, objective response rate, or other symptom derived endpoints)
    • NER Model for Trial Arm – This model will tag snippet of text it believes to be a cohort or clinical trial arm. For example, an experimental group, active comparator, placebo, etc.
    • Text Classification Module – Classify documents into one or many categories based on their text, such as emails, invoices, clinical records, etc.
    • Boolean Question Answering – Users now have the option to return true/false results for a question (e.g. “Is this document in English?”) rather than trying to find an answer directly from the text.

Bug Fixes

  • We’ve made some small but noticeable performance improvements for our user interfaces and data retrieval capabilities.
  • Clinical Trials had a brief lapse in indexing new records – this has been resolved, and all missing records are accounted for.

Vyasa Layar 2.55.0

April 2022

What’s New

Relationship extraction in Vyasa Layar software.
  • Relationship Extraction in Layar. We’ve enabled a new visual feature that shows you relationships between two or more concepts within a text-based document! For example, identifying the reactants and chemical reactions needs to generated a specific product (see featured image above).
  • Layar Search Expansion Using Ontologies. Expand your search to include any synonyms for a term, based on Layar Ontologies! When submitting a keyword or boolean search in Layar, terms will be run against any ontologies that exist in their instance. Any terms with synonyms/are synonyms can be incorporated into the search by clicking “Expand search” underneath the search bar.
  • Dynamic Connections to Sybase & Oracle Connectors. Users now have the option to reference their Sybase or Oracle tables dynamically, rather than a snapshot of those datasets at the time of creating the connector.
  • Clinical Trial Eligibility Criteria. Oftentimes, the eligibility criteria of a registered clinical trial bundles the inclusion and exclusion criteria together into the same snippet of text. We now automatically parse these two properties out into separate distinct metadata sections for QA or other Layar pursuits. We also keep the original eligibility criteria property, as well.
  • Major Question Answering Additions!
    • Document Section QA. Users can now focus their queries on specific areas of the text! Unstructured texts are automatically parsed by Vyasa into their respective headings / subheadings, so you can submit a question on specific sections. For example, you can ask “What protocol was used for staining the protein targets?” in the ˆmethods section of a publication, rather than the entire document.
      • This not only improves the speed of your bulk query jobs, but also gives you more refined responses to the specific areas you wish to examine in your documents.
    • Query Understanding Enhancements. This secondary query understanding pipeline kicks into gear when an input question returns low or zero results with our default pipeline. This secondary pipeline can also be leveraged via the API as its own endpoint (see the query_expansion endpoint for the QuestionApi class).
    • QA Benchmarking. Users can now follow along with specific QA projects & models to understand the precision and recall of their models. Currently only available as API endpoints.

Vyasa Layar 2.54.0

March 2022

What’s New

  • Highlighting for Ontologies Now Available! In addition to highlighting named entities in a document, Layar will now automatically tag any terms (or their relevant synonyms) based on an uploaded ontology. Simply select the ontology (or ontologies) of interest under the Concept Types legend, and Layar will automatically highlight any terms in the text that are from those ontologies.
  • Hierarchical Table-Converted Ontologies. Take a table based file (csv, tsv, xml, etc.) and convert it into a flat data dictionary or tree-based hierarchical ontology! To learn more, check out this article.
  • Expansive Keyword Search. When you run a keyword or boolean search in Layar, you now have the option to expand your search to return all results for synonyms as well as the initial term!
  • Simpler Filter Menu. We’ve narrowed down the the filter menu to have the most widely used filters available for quick and easy utilization. That being said, those more advanced filters haven’t gone away – they still exist! If there’s a more advanced filter you’re interested in, you can click “Load More”, and you will see all of the previous filters available.

Bug Fixes

  • We’ve implemented additional security improvements to the Layar system.

Vyasa Layar 2.53.0

  • PDF Preview Updates. Our PDF viewer has been updated! You may see a different layout than in previous Layar releases. The viewer still contains all prior functionality, but loads much quicker (especially for those pesky larger PDFs), has a higher resolution, and includes a built in search. Users can also view the Table of Contents for a PDF, if the PDF was provided with Table of Contents metadata.
  • PDF Table Extraction Updates. We’ve made some major improvements to extracting tables from PDFs. Here are the highlights:
    • Instead of using the “Extract Table” button and scrolling to the page of interest, users can scroll over to the page of interest, click and drag to create a boundary of the table they would like to extract, and click “extract table” to trigger our automated table extraction feature.
    • Tables extracted in this manner will generate a downloadable CSV, and will be linked to the parent document as a “Related Document”, file type: table.
    • Users can accurately extract tables with merged columns, invisible cell boundaries, or multiple header titles!
    • Automated table extraction can also handle tables in landscape orientation, as well as tables that spread across multiple pages!
  • We’ve made some improvements to processing time for large PDF uploads.

Bug Fixes

  • Documents from our Canonical Data Fabric were being given an incorrect URL, making it difficult to link back to a document in Layar from the other Vyasa applications. This has been resolved.
