Abstract

A method for assisting a user of a terminal in constructing a search query for a content search engine, comprises the steps of collecting, in a history collection, descriptors of content presented at the terminal, receiving a request to construct the search query, selecting from the history collection a plurality of descriptors to form an assistance collection, presenting the assistance collection to the user and allowing the user to construct the search query from the descriptors of the assistance collection.

Claims

1. A method for assisting a user of a terminal in constructing a search query for a content search engine, the method comprising the steps of:

collecting descriptors of content presented at a terminal in a history collection;

receiving a request from a user to construct a search query;

selecting from the history collection a plurality of descriptors to form an assistance collection according to user requirements;

presenting the assistance collection to the user; and

allowing the user to construct the search query from the plurality of descriptors of the assistance collection.

2. The method according to claim 1, further comprising the step of

collecting descriptors of content presented at a plurality of terminals in an external history collection;

and

selecting from the external history collection an external plurality of descriptors to form an external assistance collection.

3. The method according to claim 1, further comprising the step of

collecting, in the history collection in addition to the descriptors, metadata identifying content presented at the terminal, including at least one of:

a content identifier, type, time of presentation, duration of presentation or rating.

after inserting the selected descriptor to the search query, selecting from the history collection a modified plurality of descriptors to form a modified assistance collection and presenting the modified assistance collection.

6. A computer program comprising software code adapted to perform the steps of the method according to claim 1 when executed on a data processing terminal.

7. A computer readable storage medium comprising the computer program of claim 6.

8. A system for assisting a user of a terminal (101) in constructing a search query for a content search engine, the system comprising:

a descriptors extractor (103) configured to collect in a history collection (104) descriptors of content presented at the terminal (101);

a query assistant (105) communicating with the history collection and configured to

select from the history collection (104) a plurality of descriptors to form an assistance collection,

present the assistance collection to the user and

allow the user to construct a search query from the descriptors of the assistance collection.

9. The system according to claim 8, further comprising

a history aggregator (131) configured to collect in an external history collection (132) descriptors of content presented at a plurality of terminals;

wherein the query assistant (105) is further configured to select from the external history collection a modified plurality of descriptors to form a modified assistance collection.

10. The system according to claim 8, wherein

the history collection (104) comprises a predefined set of descriptors.
