| 20080243482 | Method for performing effective drill-down operations in text corpus visualization and exploration using language model approaches for key phrase weighting - The invention relates to a method and an apparatus for performing a drill-down operation on a text corpus comprising documents, using language models for key phrase weighting, said method comprising the steps of weighting key phrases occurring both in a foreground language model, which contains a selected document cluster of said text corpus, and in a background language model, which does not contain said selected document cluster, by calculating for each key phrase a key phrase weight comprising a ratio between the foreground weight of said key phrase and a background weight of said key phrase, and assigning documents of the foreground language model to cluster labels which are formed by key phrases having high calculated key phrase weights. | 10-02-2008 |
| 20090150378 | Method for estimating a prestige of an entity - A method and an apparatus for estimating a prestige of an entity, as for example a firm, company or name, is disclosed wherein a score value is assigned to an entity as a function of an occurrence of terms associated with said entity in search results. The search results are obtained by searching an information space such as the internet. This enables, for example, companies or divisions, to infer their public standing from an analysis of search results obtained through internet search engines. It is possible to compare a plurality of entities with respect to each other in an automated fashion. | 06-11-2009 |
| 20090198593 | Method and apparatus for comparing entities - A method and apparatus for comparing entities, such as companies or trademarks, based on available pricing and feature information regarding goods or services provided by the companies. Web services, e.g. price finding robots, are employed to obtain pricing and feature information for similar products from different companies. Products having similar features but derive from different companies can be grouped to clusters and be analyzed with respect to average pricing levels. Data formats for pricing and feature information stemming from different web services may be automatically retrieved and mapped into a common format. The method allows to evaluate systematic deviations in the company's pricing policies or to detect if companies do not have a matching product portfolio. One can also estimate the prestige or acceptance of a company or brand as a function of prices tolerated by the underlying market. This may facilitate marketing strategies. | 08-06-2009 |
| 20090204573 | Computer-based method of measuring the usability of a web site - Computer-based method of detecting the guidance performance of an information driven web site for a user seeking a desired content, wherein a transition value is assigned to each click based on the effectiveness and efficiency of transition between web pages of such web site, and an indicator value is determined by combining these values into a metric, which reflects guidance performance of such web site. | 08-13-2009 |
| 20090204595 | Method and apparatus for tracking a change in a collection of web documents - A method and an apparatus for tracking changes in a collection of web documents, for example, provided by a web site. The web documents are retrieved at a first assigned point in time and a second assigned point in time. Then a similarity measure for a combination of a retrieved web document at a first assigned point in time and a retrieved web document at a second assigned point in time is calculated for determining pairs of corresponding web documents. By comparing said calculated similarity measure of a pair of corresponding web documents with predetermined thresholds for the similarity measure a change in the content of the corresponding web document between the first assigned point in time and second assigned point in time is detected. Instead of referring to identifiers like URLs for web pages the content similarities of web pages are considered. The proposed strategy facilitates the work of marketing analysts. | 08-13-2009 |
