MORE DETAILLED DESCRIPTION OF THE INVENTION

In the figures, the same references denote identical or similar elements. Figure 1 shows a system according to the invention. Said system comprises at least a mobile device 1 having at least a local application 11 providing local services, a local search engine 10 and a user output interface which is preferably a display device 5.

The mobile device 1 may be for example a Personal Navigation Device ('PND'), or a smart phone; said mobile device 1 may be typically used in a vehicle, but can also be used by a pedestrian, a cyclist, or any transportation means. Said mobile device 1 comprises geolocating means to determine a current location of the mobile device 1, such as a GPS receiver or any other equivalent device.

Further, the system comprises remote servers 3 having remote resources; said servers are connected to the internet network, and support a variety of resources, called 'remote resources' since they are located remotely from the mobile device. Said servers 3 are able to provide a plurality of services, some of them will be called in the following 'target services' as they are involved in the method of collection of information detailed below.

Further, the system also comprises at least a host server 2 adapted to be connected to said remote servers 3 through internet .

A communication channel 4 can be established between said mobile device 1 and said host server 2, said communication channel 4 having at least a wireless portion 40.

The method according to the invention involves several steps that are detailed here below.

Keyword input step

The mobile device 1 comprises a local search engine 10, said local search engine is adapted to accept an input of a keyword. Said keyword is a character string, which is entered one character after another, preferably by a touch screen interface available through the display of the mobile device, but it could also be entered thanks to voice recognition and in particular character recognition.

Advantageously according to the invention, the local search engine 10 displays a list of possible choice corresponding to the already entered characters, as depicted on Figures 4a and 4b; in Figure 4a, two character 'P' and 'h' have been entered, and a third character ' a ' has been appended in Figure 4b; the longer is the string of characters, the more selective is the prompted list 16 below the input field 15.

In order to have an intelligent and efficient search, several functionalities could be used:

- At the very first key entered, it is proposed at the top on the prompted list the previous keyword input that begin with this key. It will allow the user that uses frequently the same searches to strike less key to select the desired keyword.

- Through linguistic dictionary, a same word written in different languages will be recognized as the same word, for instance 'Bruxelles' will be recognized as 'Brussels'.

- Aliases could be used as shortcuts, said shortcuts configuration is saved into user preferences. For instance the input key 'medic' will be a search for every pharmacies and hospitals near the user position. Aliases save time, it allow the user to make complex search with a single keyword .

- A phonetic algorithm will be used to allow 'phonetic' writing. For instance, input keyword 'resto' will be recognized as 'restaurant'.

The list of possible choices displayed below the input field further includes all type of data available in the mobile device 1, like the people contacts, the music playlists, music directory elements, message topics, local application names (like 'Photoshop™' in the example), or any other information present in the mobile device including members of previously selected keyword lists.

Once a particular keyword has been selected by the user, as illustrated by the keyword 17 'pharmacy' in Fig 4b, the local search engine 10 may prepare a request to be sent to the host server 2.

Determining search parameters

The request comprises the selected keyword and a set of search parameters. Said search parameters may comprise the current location of the mobile device, the current time, and may further comprise a set of user preferences, (like the topics of interest, the preferred locations, the language preferences, etc), a set of user previous requests (like the preferred websites) . It also includes a keyword profile that describes in a few keywords the user (like 'truck driver' or 'business man') .

In the case when the mobile device, as navigation system, performs a guiding operation from the current location to a destination, an itinerary or route is defined together with an itinerary corridor. Said itinerary corridor may be defined by all areas located at a distance from the itinerary which is below a predetermined distance.

In this case of guidance, the search parameters may also include one criteria among the following group of criteria :

- locations included or close to the itinerary corridor ,

- the distance from the current location to the target service location.

Remote search step

The request is transmitted from the mobile device 1 to the host server 2. This request, referred to as 50 in Figure 2, is not necessarily a 'HTTP' request, it may be a proprietary request designed to minimize the volume of data transmitted over the wireless portion 40 of the communication channel 4. The host server 2, in turn, analyses the content of the request 50, and prepare adapted copies 51,52,53 of the request to be transmitted to the remote servers 3, these adapted copies are standard HTTP client requests.

Hence, the process is optimized since a single request from the mobile device will be duplicated in several requests from the host server 2 to the remote servers 3 over high data rate internet.

In the example illustrated, the 'pharmacy' request will be forwarded as adapted copies under HTTP standard 'client' request to the 'yellow pages™' website 31, to the ' Tellmewhere™ ' website 32, and/or to any healthcare website 33, with appropriate parameters like the current location for example.

As a result, information about target services relevant to the inputted keyword is collected from the remote resources 31-33. Remote servers 3 transmit responses 61, 62, 63 to the host server 2. In the exemplified case, a first list of pharmacies in the concerned area is sent from 'yellow pages™' website in a first message 61, a second list of pharmacies in the concerned area is sent from 'Tellmewhere™' website in a second message 62, and a third list of pharmacies is sent from the city healthcare website in a third message 63. Said host server 2 discard all unnecessary information from the resulting information in the three messages 71,72,73 and sends the relevant result to the mobile device 1.

Sorting step

In this step, the local search engine sorts the collected information about target services related to the inputted keyword and to the current location and to the current time according to sorting parameters.

In the exemplified case, the three list of pharmacies coming from the three messages 71,72,73 are merged into a single list wherein the duplicates are eliminated. Then a sorting operation is performed according to sorting parameters: the search engine ranks or orders the items in the collected information by their relevance against the sorting parameters. For example, the 'pharmacy' items present in the list may be ranked by the distance of their location from the target service location, or by the additional time cost due to the detour if the user follows an itinerary.

The items whose location is outside the itinerary corridor are ignored or placed in a low ranking position if the number of items is small enough.

Different types of sorting parameters may be used by the sorting operation:

- the distance or time cost of the detour of target service location to itinerary as explained above,

- the distance of target service location to the target service location, as explained above,

- working hours of target services, which is taken into account to allocate a low ranking or ignore a service that is closed or will be closed by the time the user arrives at this location; this is made possible when the itinerary comprises the estimated time of arrival at intermediate locations and destination,

- completion of information available for target services, which is taken into account to allocate a low ranking or ignore a service for which only partial information is available, for example missing working hours ,

- a set of user preferences, for example a higher ranking may be allocated to a service which has already been used by the user,

- popular rating of target services, which is taken into account to modify the ranking according to the ranking allocated by other users; for example if the keyword would be 'restaurant', the popular rating parameter includes the weight of positive/negative feedbacks of previous customers .

- social network feedbacks of target services, higher rank will be given to target services that have been selected and used by users that share keyword profile with the current user.

Further, if the mobile device may be located in a vehicle having a particular size like a truck and/or a particular fuel type like LPG.

In this case, the sorting step filters the results according to the vehicle fuel type and size, whereby only target services located in accessible locations to this vehicle type and size are selected; for example, if downtown traffic is forbidden to trucks, an 'item' pharmacy located in downtown area will be allocated a low ranking if the concerned vehicle is a truck.

Presentation step

As already explained, the mobile device comprises an output interface. This output interface may be an audio interface using voice synthesis, which spells the result of the sorting step.

However, advantageously according to the invention, the mobile device 1 uses a display device 5 to present the sorted information about target services. Preferably, the mobile device uses a graphical interface, for instance a map display, as exemplified on Figure 3. As shown in Figure 3, the mobile device 1 is located at the current location 24 and is under guidance along an itinerary 23 to the destination 25.

The user has selected the keyword 'pharmacy' as already explained. The result of the sorting step is displayed graphically: in the depicted case, five items corresponding to the keyword and to other search parameters and sorting parameters are displayed.

When the user interacts with a service, the device sends to the server a feedback with the association of user's keyword profile and said service, this information will be used for the social network sorting feature.

The item which is allocated the higher rank exhibits number ' 1 ' , i.e. 'Pharmacy Maumont, 12 rue Poupart, 93 120 Noisy le Gd', ref. 29. Other proposed pharmacy items 26,27,28,80 exhibit number ' 2 ' , ' 3 ' , ' 4 ' , ' 5 ' according to their relevance, in particular in accordance with the sorting parameters.

Of course, the user may click on one box to show additional information available about the concerned item.

It is to be noted that working hours may be displayed on the main display like in the sub-box 81 attached to the main box 80.

Additionally, previously searched items and/or other

POIs may be displayed in shadow.

Local search step

Additionally to the remote step search, the local search engine may perform a local search step in which it identifies and launches relevant local applications 11 to collect results of local services relevant to the inputted keyword and to the current location and to the current time. As a matter of fact, some local applications may include geolocated information, like POIs or other data relevant to the searched items.

In the sorting step, the local search engine merges information collected in the local search step into the information collected in the remote search step. Then the local search engine sorts said merged information according to sorting parameters, as explained above.

Additionally, in the local search step, the local search engine also searches among general purpose local services. For instances, the general purpose local services may include: a contact directory, a desktop calculator, a messaging service, a music directory, bookmarks, etc... Therefore, the input of any keyword will lead to a relevant result, even if the keyword is intended to designate a local service.

As shown in Figure 5, the method can be represented by a succession of steps: the keyword input step 91, the search parameters determination 92, the remote search step 94 , the local search step 93, the sorting step 95 and the presentation step 96.

Additionally, during the remote search step, the adapted copies 51-53 of the request may be targeted to a non-free information service. In this case, the response given by the remote resource 31-33 will contain the number of hits collected by the concerned request, but will not comprise the actual content of the available information. In this case, the sorting and presentation steps may comprise a special behaviour to notify the user about the possibility to subscribe this non-free service.

It is to be noted that the invention encompasses any other kind of services useful to users like restaurants, hairdressers, groceries, parking lots, car wash, cinemas, post office, police office, city hall services, etc... all available through a simple keyword input.
