Abstract: 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.

Abstract: 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.

Abstract: A method and apparatus for preprocessing a plurality of documents for search and presenting search result and a system for searching documents that comprises these apparatuses. The search result, for example, includes at least one candidate document. The candidate document is assigned a tree structure representing its content. The tree structure includes at least one node. The method may include presenting at least a portion of the tree structure corresponded to the candidate document in the search result.

Abstract: Techniques for processing geographical location data in a document comprise: obtaining geographical location data in the document; grading the geographical location data according to a predetermined condition to determine an associated relationship between the geographical location data; marking on an electronic map the associated relationship between the geographical location data; and presenting the marked electronic map.

Abstract: A method for checking pipeline leakage comprises: receiving detecting parameters collected by at least one sensor with respect to pipelines in its corresponding region; gathering detecting parameters collected by the at least one sensor; analyzing the gathered detecting parameters to obtain an evolutionary tendency of detecting parameters in the corresponding region of the at least one sensor; judging if the evolutionary tendency of the detecting parameters satisfies predefined features of leakage; determining that pipeline leakage exists in the corresponding region if the evolutionary tendency of the detecting parameters satisfies the predefined features of leakage. The present invention may help to determine leak regions with a leakage having small flow quantity, and provide a user with regions with pipeline leakage to be detected based on a resource constraint.

Abstract: A method and system for publishing specified content on a webpage. Specifically, an example method for publishing specified content at a specified location of a webpage includes the steps of performing sentiment analysis upon context surrounding a specified location where the specified content is to be published to determine a sentiment tendency of the context surrounding the specified location and selecting whether or not to publish the specified content at the specified location according to the sentiment tendency of the context surrounding the specified location. Embodiments of the invention help to make the webpage content more coherent, make the contents of a webpage matching in sentiment and rational in layout, improve a viewer's feeling of the webpage content, and increase website click rate and revenue. Embodiments help achieve a beneficial effect of providing a web electronic ad matching the sentiment of a webpage.

Abstract: A computer-implemented method and system for checking a chemical name. The method tokenizes the chemical name to obtain corresponding tokens; checks the chemical name according to the chemical association between chemical compositions represented by the tokens; and if the chemical name does not pass the check, replaces at least part of tokens of the chemical name that does not pass the check, and repeats the checking step. The system and method can not only help users to find and correct errors in spelling a chemical name but also check the entire chemical name at the level of chemical associations. Hence, not only chemical names that are incorrectly spelled but also ones that do not conform to chemical rules can be found, and significant help is provided to users for correcting chemical names.

Abstract: A tagging method and apparatus, including computer program products, based on a structured data set are provided, the tagging method comprising: creating classification models for respective nodes in the structured data set of an event; acquiring public opinions on the event; and tagging the opinions to corresponding nodes of the structured data set using the created classification models. The tagging method and apparatus of the present disclosure are able to provide well-ordered, focused public opinions for each event to users, and to exhibit the evolution of the public opinions along with time.

Abstract: The present invention is directed to a method and apparatus for establishing documents relationship based on user's operation upon search result. When a user uses search engine to search for documents with a query in repository, the search result may be a list of ranked documents, and these documents may contain a lot of relationship in term of the specific query. If the user clicks some search result further, and if the click and open operation meet certain conditions, for example exceed a period of time, the clicked document could be deemed as related to the search query. Furthermore it could be inferred that there is a strong relationship between different documents clicked by the user. The present invention records the relationship between documents and presents it to the user when necessary.

Abstract: The present invention provides a method and apparatus for preprocessing a plurality of documents for search and presenting search result and a system for searching documents that comprises these apparatuses. Wherein the search result comprises at least one candidate document, and each of the at least one document is assigned a tree structure representing its content which comprises at least one node, said method for presenting search result comprising: presenting at least a portion of the tree structure corresponded to said at least one candidate document in said search result.
