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: 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: An image search method and system using face detection, begins with receiving a query submitted by a user. Next a query word is searched in the query from an image resource using an image search engine to obtain an initial image collection. Any faces are detected in each image in the initial image collection which has been searched. A search for the query word in a text surrounding each image having the face in the initial image collection is performed. A determination is made whether the query word indicates at least one person's name in the surrounding text matching the query word. An image an image in the initial image collection is returned to a user in which the face is included and the query word in the surrounding text indicates the person's name.

Abstract: 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 a 3D space. Complex information, such as, the relationship between subject labels and weights of respective subject labels can be presented by displaying the 3D space. In this way, the screen size can be reduced and the user experience is improved.
