Indexing of Digitized Entities
First Claim
1. A server/client system for searching for digitized entities in a data collection comprising:
- an indexing input device for collecting basic information pertaining to at least one distinctive feature and at least one locator for each digitized entity in a set of entities from the data collection, an index database for storing index information relating to the digitized entities in the set, a search engine for receiving search directives and in response thereto performing searches in the index database, and a user client interface for receiving a search request from at least one user client terminal, forwarding the search request as a search directive to the search engine, receiving a hit list of digitized entities and returning a result of a corresponding search in the index database to the at least one user client terminal, wherein the index database is organized such that the index information for a particular digitized entity comprises at least one rank parameter, which is indicative of a degree of relevance for at least one distinctive feature with respect to that digitized entity.

Abstract
The invention relates to indexing of digitized entities in a large and comparatively unstructured data collection, for instance the Internet, such that text-based searches with respect to the data collection can be ordered via a user client terminal. Index information is generated for each digitized entity, which contains distinctive features being ranked according to a rank parameter. The rank parameter indicates a degree of relevance of particular distinctive feature with respect to a given digitized entity and is derived from fields or tags associated with one or more copies of the digitized entity in the data collection. The index information is stored in a searchable database, which is accessible via a user client interface and a search engine. The derived distinctive features and the rank parameter thus provides a possibility to carry out text-based searches in respect of non-text digitized entities, such as images, audio files and video sequences and obtain a highly relevant search result.
