A personalized data analysis method is provided, so as to find features having discrimination capability from target analysis items. In particular, a data analysis method includes: acquiring sample data; selecting discriminative features of the sample data; determining, for a target analysis item, whether it has a discriminative feature; and correlating the target analysis item with the discriminative feature in response to having the discriminative feature.

Data analysis method and system thereof

A key point based guiding navigation method, device, and equipment are disclosed. Said method includes the following steps: based on a first location and a second location, determining a plurality of navigation points from among a plurality of key points located in a predetermined indoor map, where the key points are used to represent accessible directions in the indoor map; generating navigation information for pilot based on orientation of a specific navigation point relative to a current location; and following a predefined displaying rule and based on at least part of the indoor map, displaying the navigation information and navigation point and/or second location.

Parsing XML (extensible markup language) data by performing the following operations: (i) dividing the piece of markup language into a plurality of pre-parsing segments; (ii) assigning the pre-parsing segment to a pre-parsing processor thread of a plurality of pre-parsing processor threads; (iii) determining any parsing division point(s) occurring in the pre-parsing segment so that data corresponding to a single tabular record is between each consecutive pair of parsing division points; (iv) dividing the piece of language into a plurality of parsing segments defined by the parsing division points so that each parsing segment corresponds to a single tabular record; (v) assigning the parsing segment to a parsing processor thread of a plurality of parsing processor threads; and (vi) parsing to generate a parsed tabular record corresponding to the parsing segment.

Parallel parsing of markup language data

A semiconductor structure and a method for forming the semiconductor structure are provided. The semiconductor structure includes: a substrate, at least a part of an upper surface of the substrate being a nonpolar surface or a semi-polar surface including nitride semiconductor crystals; an interface layer formed on the nonpolar surface or the semi-polar surface, and including at least one selected from a nitride and an oxynitride; and a metal layer formed on a surface of the interface layer away from the substrate.

A method of generating recommended items for a current user in an unfamiliar domain includes selecting a reference user in a reference domain different from the unfamiliar domain, where current user behavior in the reference domain and reference user behavior in the reference domain have a user similarity index which satisfies a user similarity index condition. The method further includes generating the recommended items in the unfamiliar domain for the current user according to history behavior data of the reference user in the unfamiliar domain.

Generating recommended items in unfamiliar domain

A method and system for recognizing chemical names in a Chinese document. The method includes: receiving a Chinese document including chemical names; recognizing chemical name segments in the document; recognizing non-chemical name segments in the document; and combining the chemical name segments to get chemical names based on the recognized chemical name segments and non-chemical name segments. Specific embodiments of the present invention can effectively recognize chemical names from a chemical document.

A method of recommending tags for user includes receiving a current rating of current user on current objects; determining a candidate tag set based on the current user and the current rating; ordering each candidate tag in the candidate tag set based on index value thereof; and recommending tags for the current user based on the ordering.

Recommending tags based on user ratings

A method and system for tagging original data generated by things in the Internet of Things (IoT). The method includes: performing relativity detection on acquired Web messages to obtain Web messages related to various events; acquiring address information contained in the related Web messages; determining adjacent things for various events based on the acquired address information; and tagging original data generated by the adjacent things determined using at least partial content of the related Web messages as metadata. The system includes modules for carrying out the above method.

There are disclosed a method and a device for tagging a document. The method includes the steps of acquiring structural information of the document, retrieving a content block list corresponding to a user-input tag, comparing blocks in the structural information with blocks in the content block list, to obtain similar blocks, and annotating the user-input tag at positions, which correspond to the similar blocks, in the document.

Method and device for tagging a document

Tagging methods and apparatus, including computer program products, based on a structured data set. Classification models are created for respective nodes in the structured data set of an event. Public opinions on the event are acquired. The opinions are tagged to corresponding nodes of the structured data set using the created classification models. The tagging methods and apparatus provide well-ordered, focused public opinions for each event to users, and exhibit the evolution of the public opinions along with time.

Tagging method and apparatus based on structured data set

This invention aims to provide a method and apparatus for displaying and/or browsing a multi-faceted data set containing hierarchical subject labels. In the present invention, subject labels can be located into aD space. Complex information, such as, the relationship between subject labels and weights of respective subject labels can be presented by displaying theD space. In this way, the screen size can be reduced and the user experience is improved.
