Brainspace Reports

Server Name

The local server name, not necessarily the well-known name.

Server Type

Classic server type (e.g., Runtime, Build, Analytics).

Mac Address

Unique ethernet interface identifier used in Brainspace licensing.

Customer ID

English language identifier for customer/site as it appears in the Brainspace license file.

License ID

Software generated value as it appears in the Brainspace license file.

Available Cores

Number of available CPUs detected by Brainspace.

Date

Last day of the month for the report or the date that the report was run when downloaded during a current month.

PEAK_DATASET_DOCS

The peak count of active documents during a current month. Only valid for the Runtime server. Other servers will show -1 or will be blank.

END_DATASET_DOCS

Number of active documents at end of a month or currently active documents if downloaded during a current month. Only valid for the Runtime server. Other servers will show -1 or will be blank.

TOTAL_CONNECTORS

Number of connectors configured. Only valid for the Runtime server. Other servers will show -1 or will be blank.

PEAK_BUILD_DOCS

The peak count of documents analyzed during the course of a month. Only valid for the Analytics (Build) server. Other servers will show - 1 or will be blank.

END_BUILD_DOCS

Number of documents analyzed at end of a month or currently active documents if downloaded during a current month. Only valid for the Analytics (Build) server. Other servers will show -1 or will be blank.

PEAK_BUILD_BYTES

The peak count of bytes of data analyzed during the course of a month. Only valid for the Analytics (Build) server. Other servers will show - 1 or will be blank.

END_BUILD_BYTES

Number of bytes analyzed at end of a month or currently active documents if downloaded during a current month. Only valid for the Analytics (Build) server. Other servers will show -1 or will be blank.

PEAK_CONFIGURED_USERS

The peak count of configured users during the course of a month. Only valid for the Runtime server. Other servers will show -1 or will be blank.

END_CONFIGURED_USERS

Number of users configured at end of a month or number of users currently configured if downloaded during a current month. Only valid for the Runtime server. Other servers will show - 1 or will be blank.

PEAK_ACTIVE_USERS

Number of simultaneously active users at end of a month or number of simultaneously active users if downloaded during a current month. Only valid for the Runtime server. Other servers will show -1 or will be blank. On single-host environments or environments where the Analytics (Build) and On-Demand Analytics servers are the same, unexpected server counts may appear. On deployments where datasets were loaded from disk, documents will not count against the PEAK_BUILD_DOCS, END_BUILD_DOCS or TOTAL_LIFETIME_DOCS until they are submitted for analysis (build) on that environment. If a document is submitted for

analysis to update, add, or delete metadata fields, it will be counted multiple times against the TOTAL_LIFETIME_DOCS but only once against all other _DOCSmetrics and in the current Brainspace UI’s Active document control.

TOTAL_LIFETIME_DOCS

Total number of documents actually analyzed. Only valid for the Analytics (Build) server. Other servers will show -1 or will be blank.

PEAK_INACTIVE_DOCS

The peak count of inactive documents during the course of a month. Only valid for the Runtime server. Other servers will show -1 or will be blank.

END_INACTIVE_DOCS

Number of inactive documents at the end of a month or currently inactive documents if downloaded during a month. Only valid for the Runtime server. Other servers will show -1 or will be blank.

key

The unique internal ID of the document.

responsive

This is “yes” if the document has been assigned the positive tag for the classification, “no” if assigned the negative tag, and blank if the document is untagged or given a tag that is neither positive nor negative.

predicted_responsive

This is “yes” if chance_responsive is 0.50 or more and “no” otherwise. A cutoff of 0.50 used with the predictive model creates a classifier that attempts to minimize error rate. Note that 0.50 is typically not the cutoff you would use for other purposes.

matches

This is “yes” if responsive is non-null and the same as predicted_responsive. This is “no” if responsive is non-null and different from predicted_responsive. Blank if responsive is null (e.g., the document is not a training document).

score

This is the raw score the predictive model produces for the document. It can be an arbitrary positive or negative number. The main use of score is for making finer-grained distinctions among documents whose chance_responsive values are 0.0 or 1.0.

chance_responsive

For predictive models that have been extensively trained, particularly by many rounds of active learning, chance_responsive is an approximation of the probability that a document is a positive example. Values are between 0.0 and 1.0, inclusive. This value is produced by rescaling the score value (x-ref).

Uncertainty

The uncertainty value is a measure of how uncertain the predictive model is about the correct label for the document. It ranges from 0.0 (most uncertain) to 1.0 (least uncertain). The uncertainty value can be used to identify documents that might be good training documents. Uncertainty is one factor used by Fast Active (x-ref) and Diverse Active (x-ref) training batch selection methods. This value is produced by rescaling the chance_responsive value.

term1, score1,...term 8, score 8

The terms that make the largest magnitude contribution (positive or negative) to the score of the document, along with that contribution.

Training Rounds

The training round number in the series of classifier training rounds.

Number of Docs

The number of new documents added to the training set for the training round. It includes new documents from both the training batch, if any, and the ad hoc tagged documents, if any. This count does not include documents that were in the training batch on the previous round. The count includes documents with changed labels. The count is also not reduced if some document tags were removed from the previous round’s training batch or converted to non-classification tag values on the current round. For that reason, the Number of Docs count is never negative.

Net Manual Docs

This is the net number of new documents contributed by ad hoc tagging to the training set on the current round. It takes into account documents that have new positive or negative tag values. It also takes into account documents that had a positive or negative tag value at the end of the previous training round but no longer have that value. For that reason, the Net Manual Docs value can positive, negative, or zero.

Classification Model

This column specifies the method that was used to create the training batch, if a batch creation method was used on a training round. If the only ad hoc documents were tagged in a training round, the value REVIEW is used.

Cumulative Coded

The total number of documents in the training set at the end of a training round.

Cumulative Positive

The total number of documents with positive tag values at the end of a training round.

Cumulative Negative

The total number of documents with a negative tag value at the end of a training round.

Round Positive

The net change in the number of positive training documents since the previous training round.

Round Negative

The net change in the number of negative training documents since the previous training round.

Stability

This is an experimental measure of how much recent training has changed the predictive model. While presented for informative purposes, Brainspace does not recommend its use for making process decisions.

Consistency

This is the proportion of training set examples where the manually assigned tag disagrees with the prediction of a minimum error rate classifier (x-ref Prediction Report).

Unreviewed Docs

Number of documents that are not tagged either positive or negative. Populated only for validation rounds (x-ref).

Estimated Positive (lower bound)

Lower bound on a 95 percent binomial confidence interval on the proportion of positive documents among the documents not yet tagged as either positive or negative. Populated only for validation rounds (x-ref).

Estimated Negative (lower bound)

Upper bound on a 95 percent binomial confidence interval on the proportion of positive documents among the documents not yet tagged as either positive or negative. Populated only for validation rounds (x-ref).
