Renamed account and account_id to workspace

With this release, all instances of account or account_id in the API are now workspace. Please update your code accordingly. This change reflects the Settings overhaul Luminoso introduced in late 2019 that provides better permissioning on the Organization and Workspace levels.

The legacy_term_format parameter now defaults to “false”

The legacy_term_format parameter on the Vectorize text endpoint now defaults to false, instead of true.

If you need time to update code, you can specify true and continue to receive the array format for terms and fragments. Otherwise, you do not need to specify anything for this parameter.

On March 27, 2021, the parameter will be completely removed, and modern object-style terms and fragments are the only available output.

Specify which fields to return when getting documents

Now, when you call the Get Documents endpoint you can choose to specify an optional fields parameter that limits the output you receive to only the fields that you specified. For instance, if you specified doc_id and metadata, you would see only these two pieces of information for each document that your search returned.

Since it creates smaller API calls, this change saves bandwidth and helps limit your search to only the information you need. This is especially useful for customers who use scripts.

Clusters now display in order by volume

We resolved a problem that affected the Galaxy feature and the What are the largest clusters of conversation? card in Highlights. Now, Highlights displays conversation clusters in descending order, with the highest-volume clusters at the top. Suggested concepts in Galaxy are also grouped in descending order of volume.

Drivers: Trend Analysis XLSX now downloads correctly

Now, when you open the Drivers: Trend Analysis feature and click Download XLSX, the XLSX downloads properly and does not display an error message.

Drivers feature export includes all saved concepts

Now, when you export selections from the Drivers feature, the download matches your selections in the Daylight app. This change ensures consistency between your in-app experience and downloads.

To export an XLSX or CSV file from Drivers, open the Drivers feature and click Download XLSX in the Download & share this data pane. The XLSX downloads.

New usage meter for uploads

With this release, we introduce a new usage meter on the upload page. This meter provides greater visibility into your organization’s data usage and how your uploads will affect your overall use.

Now, when you upload new documents in Daylight on the Create a project page or the Upload data page for additions to existing projects, you now see a usage meter that reflects the total usage for all workspaces in your organization.

In the meter, dark blue represents already uploaded documents, light blue represents the documents you are uploading now, and white represents your unused documents. If your upload would exceed your document limit, the meter displays a dotted line that indicates the limit.

Redesigned Usage tab

Beginning with this release, the Usage tab under Settings includes several key updates. These changes are available to anyone with Workspace Admin permissions or higher. Note: If your permissions are lower than Workspace Admin, you no longer have access to this tab.

The changes include:

  • Workspace usage information that rolls up to the organizational level for greater transparency.

  • A usage meter that displays the current count of uploaded documents relative to the total document limit.

  • Fields that display the numerical value of uploaded documents, the total document limit, and the percent of total documents used.

  • An enhanced monthly usage table with expandable rows that display which workspaces contributed to a month’s document uploads or refunds.

Create a workspace

Now, users with the Organization Admin role can easily create workspaces on the Organization tab of the Settings page.

To create a workspace

  1. Access the Settings page by clicking either the dropdown caret by your username or next to Projects in the top menu. The Settings page opens.

  2. Select Organization from the Settings menu.

  3. Click Create a workspace. A Create a new workspace window opens.

  4. Enter a name for your workspace and click Create workspace. The window displays a success message.

  5. Open the new workspace using the link or by navigating to the Workspace tab in the Settings menu.

Moved match type and sentiment icons

With this release, we moved the icons for exact and conceptual matches and for positive and negative sentiment directly to the left of the document preview. This change displays more matching document previews for a selected concept. It also makes document previews easier to scan by type.

Drivers no longer crashes if no drivers are suggested

Before, if you selected a score field for a dataset where most documents didn't have that score value, Daylight couldn’t suggest any drivers. The feature would crash and return a generic error message.

Now, if you open the Drivers feature and apply a score field that only applies to a few documents, Daylight displays a more specific error message that says "Sorry, there are no drivers returned for your current selections. Please adjust your selections.”

The rest of the UI remains accessible, so you can easily choose another score field.

  • Science: Improved handling of collocations


  • Galaxy: The Galaxy no longer displays concepts with all zero vectors

Improved handling of collocations

In this release, we improve the handling of collocations, or groups of words. When Luminoso processes your dataset, it creates collocations out of groups of words that are significant when used together, such as “dining room.” Previously, Luminoso would not collocate a group of words with a negative term in the middle. Now, a phrase like “no issues were resolved,” in which the negation begins the collocation, is conceptually identical to “the issue was not resolved,” which contains the negation in the middle of the collocation.

This change affects all 15 languages that Luminoso supports. You’ll see this change when you build a new project, update or rebuild an old project, or do not open a project for six months (which triggers an automatic rebuild). To see this change in Compass projects, you must rebuild each classifier.

This change will affect each project differently. If your dataset contains a high number of negative phrases, you may see a change in your top 500 concepts or a slight difference in numbers of conceptual match scores.

Galaxy no longer displays concepts with all zero vectors

Because the Galaxy represents associations between concepts, it no longer displays concepts that do not relate to other concepts. It is unusual for a concept to have no associations, and this scenario could exclusively happen if a concept only appeared by itself in every document. It could also happen if the concept was part of a collocation unique to its dataset and appeared alone in every document. This also means that the the concept did not exist in the background space.

Now, the Galaxy does not display these zero vector concepts. Concepts with zero vectors will continue to display in the Volume, Sentiment and Drivers visualizations, if appropriate.
