The invention is directed to searching for assets, and more particularly, to searching for assets based on usage rights.
Search engines today are notoriously fast at performing full text searches on large data stores of items. A user may issue a keyword search for querying a repository of tens, or even hundreds of millions of items, and within a matter of seconds he receives his search results.
A drawback with conventional search engines is that users often spend considerable time reviewing the search results they receive, only to find that many, or possibly all of the search results are not appropriate for them. This is particularly problematic with multi-media repositories, wherein a user searches for media content to license. After receiving his search results with specific media content items, the user reviews the media content, decides which one or more pieces of content he would like to license, and fills out a request to license the desired pieces of media content . . . only to find out that the rights he requested to license are not currently available. For example, the desired media content may have already been licensed exclusively to someone else in the user's specific territory, or worldwide; or to someone else for use in the user's specific industry.
The gain in speed with ultra-fast search engines is thus heavily offset by the waste in time in reviewing the search results and discovering that they are not appropriate.
Thus there is a need to enhance search engines for media repositories in order to filter out results that are not available for licensing as desired by a user.
Non-limiting and non-exhaustive embodiments of the present invention are described with reference to the following drawings. In the drawings, like reference numerals refer to like parts throughout the various figures unless otherwise specified.
The invention now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments by which the invention may be practiced. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Among other things, the invention may be implemented in different embodiments as methods, processes, processor readable mediums, systems, business methods, or devices. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.
The present invention relates to media databases and search engines. Using embodiments of the present invention, a user may search a media database to retrieve media content he would like to license, and be assured that the search results only include media content for which rights are currently available for the user's desired license.
Reference is now made to
Digital asset manager 110 may be part of a licensing clearinghouse, which arranges license agreements for users who wish to license media for specific purposes. A user, for example, may wish to license a celebrity image for use in advertising at trade shows, or for use on a commodity of merchandise, in one or more specific countries, and for a specific time period. To find images of interest, the user issues a search query to a search engine 140 with appropriate key words, and retrieves images from media database 120 that match his search criteria. The user reviews the retrieved images, and may then generate a request to price and license one or more images for his specific purposes.
The system of
A search engine 140 is operative to receive keywords and filter criteria from a user, and identify a plurality of media files, or representations thereof, which satisfy the user's search criteria. A web interface 150 provides the user with a graphical interface for issuing search queries and for reviewing query results. In conjunction with vocabulary manager 130, an indexor 160 is used to map user-supplied key words that arrive within a search query into a vocabulary for cataloging media content (“the cataloging vocabulary”) managed by vocabulary manager 130.
A rights manager 170 manages a database 180 of licensing rights that are associated with media files in media database 120, and maintains statuses of which rights are currently available for licensing. A rights filter 190 is used to filter search results generated by search engine 140, to exclude media files that are not currently available for licensing to the user. Rights filter 190 ensures that results returned to a user are suitable for licensing as specified by the user. Operation of rights filter 190 is described in detail hereinbelow with reference to
Reference is now made to
At step 240, search engine 140 performs a database query on media database 120, using the vocabulary term(s) converted by indexor 160 from the key words supplied by the user Generally, search results are in the form of references to media files in media database 120, or representation thereof such as thumbnail versions of the images, or both.
At step 250, rights filter 190 consults with rights manager 170 to eliminate those search results produced by search engine 140 that are not currently available for licensing as indicated by the user. Finally, at step 260 the filtered search results are transmitted to web interface 150 and displayed to the user for his review and possible licensing.
In accordance with an embodiment of the present invention, the rights filter uses a rights codification to determine which search results have available rights that match the user's licensing requirements. In this regard, reference is now made to
The present invention uses a variety of different data structures to represent rights domains. Shown in
In addition to the hierarchical data structure of
Embodiments of the present invention use as many data structures as necessary to model the entirety of relevant licensable rights domains. Together, these data structures provide the REL for expressing all licensable rights.
Also shown in
It will thus be appreciated by those skilled in the art that media objects have bit strings associated therewith, which codify the subsets of rights that are available for the objects. Rights filter 190 efficiently uses these bit strings for comparing rights desired with rights available, via logical Boolean operations. Specifically, if X is a bit string representing the rights desired by a user for licensing, and if Y is a bit string representing the rights available for a media object, then in order to satisfy the user's requirements Y must have a “1” in every bit position where X has a “1”; equivalently, the bit string (NOTX) OR Ymust have a “1” in all of its bit positions.
Some search engines are optimized for full text search, and in order to benefit from this optimization, the present invention uses text strings for rights codification in an alternative embodiment. By using text strings, rights filter 190 may be eliminated from the system shown in
As shown in
In accordance with an embodiment of the present invention, when a user issues a search query, the query includes information about specific rights that the user desires to license, in addition to keywords supplied by the user. In this regard, reference is now made to
Usage Type Domain—for advertising use in magazines
Geographical Region Domain—for use worldwide
Industry Type Domain—agriculture
These user rights requirements are converted into appropriate parameter strings, such as UTD_ADV_MAG, GRD_WLD and ITD_AGR. In turn, these parameter strings are included in the search query as hidden values. The full text capabilities of the search engine returns results that correspond to the user's search criteria, and that also satisfy the hidden parameter string requirements. As a result, only those media objects that are available for licensing for the required usages, regions and industry types, are included in the search results.
It will thus be appreciated by those skilled in the art that the present invention enables users, when searching for media to license, to specify intended uses of the media; and limits search results to those media objects that are available to be licensed for the specified uses. The present invention supports this capability in a highly efficient way that provides scalability to millions of media objects. The present invention leverages rights data efficiently with modern search engines, to support rights-restricted searching without compromising performance for large scale implementations.
In reading the above description, persons skilled in the art will realize that there are many apparent variations that can be applied to the methods and systems described. Thus it may be appreciated that the present invention is not limited to licensing of media content. The present invention is of great benefit for many commercial applications that provide on-line searchable catalogues for digital data, digital program modules, media storage devices (e.g., DVDs), rental equipment (e.g., cars, machines), or other items that have licensable rights and/or limited availability.
