Embodiment Construction

[0015] Exemplary embodiments of the present invention are described in detail below.

[0016] according to figure 1 The block diagram for performing a search on database 1. For the sake of clarity, the search engine is not shown. The search result is processed in the processing module 2. With the help of GUI 3 (graphical user interface), the search results processed by the processing module 2 are presented.

[0017] Generally, search engines provide a large list of results and evaluate metadata. In this state, the result list is unspecified. Therefore, the search result ranking is improved by using further criteria, including user profiles4. This user profile 4 can generally be regarded as a filter for filtering out results that match the subjective level of importance.

[0018] For example, use the history 5 of user behavior to configure the user profile 4. For example, this history 5 represents the user's "view result" behavior. Using this history, the ranking of search results ...

Abstract

Search engines for searching within home networks shall be optimised. Therefore, it is suggested to dynamically adapt a weight of an individually metadata of a data unit of the database (1) by analysing an external database. For example, web page information (6) is used to individually influence the ranking of the search results.

Description

Technical field [0001] The present invention relates to a method for searching at least one data unit in a database of a home network. The method includes the steps of: assigning individual metadata to each predetermined data unit of the database, wherein each individual metadata includes a specific weight and is based on the metadata. The specific weight of the data sorts the data units of the database. For different types of data units (for example, music, movies), specific weights (and rankings) are highly context-sensitive. In addition, the present invention relates to a corresponding device for searching data units in a database. Background technique [0002] With the growth of storage capacity in the home environment or home network, the need for a search engine that supports users to search and navigate through its media content materials is inevitable. For this purpose, content-based producible metadata describing the stored elements are automatically collected or generat...
