Jev Bulk Classifier

AI & Media Processing

Operated by Sourcelane✓ verified

A bulk text classification connector that converts lists of texts or existing text records into structured, typed columns by applying user-defined questions (categorical labels, ordered scores, and yes/no decisions). It performs multi-question classification in a single pass per text (supports up to 10 questions concurrently), returning constrained, machine-readable answers rather than free-form text. Technical outputs include selected categorical labels with confidence and per-option probability distributions, numeric ratings mapped to ordered levels with nearest-level labels and per-level probabilities, and boolean decisions with underlying probabilities; original text and source records are preserved for joinability. The connector is oriented toward large-scale automated labeling, scoring, and filtering workflows for text data.

fieldsarrayoptionalWhen reading from a results, only send these fields to the model, e.g. 'text' and 'title'. Leave empty to send the whole record.
questionsarrayrequiredThe questions to ask about every text. Each question has a 'key' (the output column name), a 'type' ('choice' picks one option, 'score' rates against ordered levels, 'noul' answers yes/no), 'instructions', and 'criteria' (options for choice, ordered levels for score).
maxItemsintegeroptionalMaximum number of texts to evaluate in this run. Set 0 for no limit. Capped at 100 per call.
concurrencyintegeroptionalHow many texts to evaluate in parallel. Higher is faster; lower it if you hit rate limits.
