| 20090070366 | METHOD AND SYSTEM FOR WEB DOCUMENT CLUSTERING - Method and System for web documents clustering are provided. The method for web documents clustering comprises the steps of: inputting a plurality of web documents; collecting information of the links and the directory structure of the inputted web documents; extracting, according to the collected links and directory structure, a hierarchical structure for the plurality of web documents; and generating and outputting, based on the extracted hierarchical structure, one or more clusters of the plurality of web documents. In some embodiments, the hierarchical relations of the generated clusters can also be outputted at the same time. Compared with the prior art, the method and system for web documents clustering according to the present invention can improve substantially the accuracy and efficiency of the web documents clustering. | 03-12-2009 |
| 20090077126 | METHOD AND SYSTEM FOR CALCULATING COMPETITIVENESS METRIC BETWEEN OBJECTS - Method and System for calculating competitiveness metric between objects are provided. The method comprises the steps of: obtaining a first object and a second object, the first and second objects having a first profile and a second profile, each composed of a plurality of attributes, respectively; normalizing the first profile and the second profile with reference to ontology information; and calculating, based on the normalized first and second profiles, a competitiveness metric between the first and second objects. In one embodiment, the ontology information is a common attribute name vocabulary, and the step of normalizing is configured for adjusting the structures of the first and second profiles to a unified profile structure, computing the sub-metrics between the corresponding attributes in the unified profile, and computing the weighed sum of the sub-metrics as the final competitiveness metric of the first and second objects. In another embodiment, the ontology information is an object category tree, and the step of normalizing is configured for mapping the first and second profiles to one or more nodes in the object category tree, computing the probabilities of mapping the profiles to different nodes, and then, based on the obtained semantic distances between the nodes, computing the final competitiveness metric according the probabilities and the semantic distances. | 03-19-2009 |
| 20090083244 | METHOD AND SYSTEM FOR SUBJECT RELEVANT WEB PAGE FILTERING BASED ON NAVIGATION PATHS INFORMATION - Method and system to utilize the set of navigation paths of web pages as the contextual information for subject relevant web page filtering with high accuracy are provided. The method comprises the steps of: obtaining all web pages in one or more web pages collections; collecting information of the links among the obtained web pages; extracting, based on the collected links, a set of navigation paths of each of the obtained web pages; and filtering the obtained web pages based on the extracted set of navigation paths to obtain desired web pages. In some embodiments, the extraction of the navigation paths is preferably performed on the navigation links of the web pages. Therefore, the method also comprises the process for deleting non-navigation links from all the links of the web pages. Compared with the prior art, the present invention can utilize the contextual information of the web pages for web page filtering in a more sufficient way, thereby improving the accuracy and objectivity of the web page filtering. | 03-26-2009 |
| 20090125549 | METHOD AND SYSTEM FOR CALCULATING COMPETITIVENESS METRIC BETWEEN OBJECTS - Method and System for calculating competitiveness metric between objects are provided. The method comprises the steps of: obtaining a first object and a second object; selecting, from all the relation instances stored in a relation instance repository, associated relation instances related to the first and second objects; and calculating, based on the selected associated relation instances, an extensional competitiveness metric S | 05-14-2009 |
| 20090327338 | HIERARCHY EXTRACTION FROM THE WEBSITES - The present invention provides methods and systems for building object hierarchy. The method includes: obtaining a set of web pages from a website; conducting an inter-page analysis on the obtained web pages to extract a hierarchy of the web pages; conducting an intra-page analysis on each of the obtained web pages to identify the semantic blocks within the web page and extract a hierarchy of the semantic blocks for all the web pages; and fusing the hierarchy of the semantic blocks with the hierarchy of the web pages to generate a coordinated hierarchy. In one embodiment, the nodes on the generated coordinated hierarchy are then mapped into corresponding objects to generate the coordinated object hierarchy. Compared with the prior arts, the object hierarchy building systems and methods according to the present invention can build the object hierarchy in a more accurate and efficient way by fusing the inter-page analysis result and the intra-page analysis result. | 12-31-2009 |
| 20100114855 | METHOD AND SYSTEM FOR AUTOMATIC OBJECTS CLASSIFICATION - The present invention provides a method and system for automatic objects classification. The method comprises: acquiring a set of objects; classifying the objects based on query log to generate a first classification result; classifying the objects based on ontological information to generate a second classification result; and semantically fusing the first and second classification results to generate a final classification result. According to the present invention, compared with the prior arts, by semantically fusing the query log-based classification result and the ontology-based classification result, the accuracy and user-friendness of the object classification can be improved. | 05-06-2010 |
| 20110243561 | FILTER, COHERENT RECEIVER DEVICE AND COHERENT RECEIVING METHOD - The present invention relates to filter, coherent receiver device and coherent receiving method. The filter is used for converting a partial response signal into a full response signal, wherein the filter uses the following transfer function H | 10-06-2011 |
