A computer-implemented method performed at a server system having one or more processors and memory, the method comprising receiving a set of curated documents comprising one or more documents identified as being relevant to a sector, analyzing the set of curated documents to determine one or more words and a count of each of the one or more words for all documents of the curated set of documents, further analyzing the set of curated documents, by analyzing one or more n-grams based on the one or more words, determining a first score based on a term frequency and a global document frequency of each of the one or more words of each of the one or more n-grams, determining a document vector based on averages of the first score, where the document vector comprises a perfect document for the sector, and storing the document vector in the data store.

Disclosed herein are techniques and systems for classifying and moderating text using a machine learning approach that is based on a word embedding process. For instance, word embedding vectors may be used to determine clusters of associated text (e.g., similar words) from a corpus of comments maintained by a remote computing system. The remote computing system may then identify, within the corpus of comments, a subset of comments that include text from a given cluster that was determined, from human labeling input, to include a particular type of word or speech. Using this information, the corpus of comments may be labeled with one of multiple class labels. A machine learning model(s) may be trained to classify text as one of the multiple class labels using a sampled set of labeled comments as training data. At runtime, text can be moderated based on its class label.

Embodiments of the present disclosure provide methods, apparatus, systems, computer program products for transferring a performance of a procedure found in technical documentation for an item via an interactive electronic technical manual system (IETM) configured to provide electronic and credentialed access to the technical documentation. In one embodiment, a method is provided comprising: providing the steps of the procedure in an order in which the steps are to be carried out; and while a user is participating in the performance of the procedure: causing a particular step that is being carried out to be highlighted; receiving input of a selection of a transfer mechanism and in response: causing an indication to be displayed between the particular step and a next step to be carried out identifying where the performance has been suspended; providing a transfer window displaying transfer information; and recording the transfer information and an identifier for the indication.

An option is set on a payment card of a card issuer. A request for payment for a transaction is received by a payment server of the card issuer from a merchant device/server. The payment server requests and receives a one-time token based on the option. An authorization indicating payment was successful is sent from the payment server to the merchant device/server with a flag set, the token, and a network address. Merchant device/server identifies the flag obtains the token and sends an e-receipt for the transaction along with the token to the network address. The e-receipt accessible from the network address by a consumer associated with the transaction. Furthermore, the e-receipt is obtained by the consumer without registering personal information or contact information with the merchant, which preserves the anonymity of the consumer with respect to the merchant.

A active learning family-based review method includes selecting a document ranked as relevant by a machine learning model, identifying family documents relationally-linked to the ranked relevant document, generating a batch including the ranked relevant document adjacent to the family documents, and displaying the batch in a computing device. An active learning family-based review computing system includes a processor and a memory storing instructions that, when executed, cause the computing system to select a relevant document using machine learning, identify family documents, generate a batch including the relevant document adjacent to the family documents, and display the batch. A non-transitory computer readable medium stores program instructions that when executed, cause a computer system to select a relevant document using machine learning, identify family documents, generate a batch including the relevant document adjacent to the family documents, and display the batch.
