Abstract: Software architectures relating to machine learning (e.g., relating to classifying sequential text data. Unlabeled sequential text data may be produced by a variety of sources such as text messages, email messages, message chats, social media applications, and web pages. Classifying such data may be difficult due to the freeform and unlabeled nature of text data from these sources. Thus, techniques for training a machine learning algorithm to classify unlabeled text data in freeform format. Training is based on generation of labelling functions from lexical databases, applying the labelling functions to unlabeled text data in an unsupervised manner, and generating trained classifiers that accurately classify the unlabeled text data. The trained classifiers may then be implemented classify text data accessed from the variety of sources. The present techniques provide high-quality and efficient labeling of unlabeled text data in freeform formats.

Abstract: Disclosed is a massager, comprising an appliance body, a first massage part and a second massage part. The first massage part is connected to an end of the appliance body for massage interior of a human body; and the second massage part comprises a support, an elastic element and a first vibrating element. The support is connected to a peripheral surface of the appliance body, the elastic element is connected to the support, and the first vibrating element is connected to an end of the elastic element away from the support and located on a side of the support close to the first massage part. The technical solution of the present application can improve massage comfort of the massager.

Abstract: Disclosed is a human body massage device, comprising: a main housing provided with a first movable cavity; a massage body movably connected in the first movable cavity and movable from a first position of the first movable cavity to a second position thereof along an axial direction of the main housing; an outer support provided with a heating part for conducting heat to the massage body. The technical solution of the present application can improve the user's comfort.

Abstract: Disclosed is a stretchable massager. The stretchable massager includes an installation sleeve, a massage member and a drive member. The massage member is inserted into the installation sleeve, and a drive member is provided in the installation sleeve. A drive end of the drive member is connected to the massage member, to drive the massage member to extend or contract along a length direction of the installation sleeve.

Abstract: A method and system for removing wax deposits from a wellbore and other oil production and processing equipment using a wax removal surfactant having at least 1% alkyl polyglycoside (APG), at least 0.5% ethoxylated alcohol (AE) or alcohol ethoxysulfates (AES), and at least 1% saturated alcohol, and optionally comprising D-Limonene, wherein the wax removal surfactant solution forms a Winsor Type III or Type IV microemulsion with water and wax.
