properties of the associated available resource, the step of computing a relevancy
score being further made as a function of said individual indications of the available
resource.
In embodiments of the method, the individual indications comprise at least
one indication selected among location indications representing the location of the
available resource, ownership indications representing the ownership of the resource,
status indications representing the operational status of the resource and usability
indications representing the usability of the resource.
In embodiments of the method, the method further comprises a step of
accessing a user preferences rule,
the user preferences rule representing the preference of a user for a preferred value
associated to an indication of said individual indications, the step of computing a
relevancy score further being made as a function of the user preferences rule so that
an operational application, associated to the preferred value, has a higher score than
an operational application not associated to the preferred value.
In embodiments of the method, the computing device comprises a graphical

compare a position information relating to a computing device connected to the
communication network and a user identifier respectively to the position indication
and the accessibility indication of each resource of the collection of resources and
select a subset of the collection of resources as a function of the position and
accessibility comparison,
and a communication unit adapted to receive the position information and the user
identifier from the computing device and transmitting the selected subset of the
resources to the computing device.
The invention originates from the observation that in the context of mobile
devices comprising applications, the applications operability depends on the
availability of services the applications require. The invention also originates from the
observation that the availability of a service depends on the presence of a physical
resource providing the said service in the environment of the user.
Therefore, an idea on which the invention is based consists in filtering
applications as a function of operational applications, the operational applications
being determined as a function of the availability in the user environment of the
services the applications require.
Aspects of the invention are based on the idea of determining the
operational applications by comparing the available resources in the user
environment to the required services, and finding matches between the available
resources and the required services so as to fulfill all required services of an
application.
Aspects of the invention are based on the idea of calculating a relevancy of
operational applications, which are associated to matching resources, on the basis of
additional data specific to each of the matching resources.
Aspects of the invention are based on the idea of calculating the relevancy
score as a function of individual properties in the additional data of the matching
resources, and balance the relevancy score using preferences defined by the user in
relation to the value of one of the properties.

(GUI) displayed on the screen of the mobile device when the method represented in

workplace.
Detailed description of the embodiments
Figure 1 shows an example of a set of connected resources 1, which are
interconnected through the internet network 2. More precisely, two printers 3 and 4, a
lamp 5, a distant server 6, a framework server 30, and a video screen 6 are
interconnected, as well as a mobile phone 7. Any other types of connected resources
may be connected to the internet network 2.
The mobile phone 7 comprises data storage in which a plurality of
applications is stored. A graphical user interface (GUI) displays, on a screen 8 of the
mobile phone 7, a selection of applications, which are recommended to the user by a
recommendation system 9. Figures 4 and 5 illustrate examples of displayed icons in
two situations. The two situations are respectively when the user, who owns the
mobile phone 7, is with his mobile phone 7 at his home, and when the user is at his
workplace. The recommended applications are represented on the screen as icons 40
each corresponding to one recommended application. Each application
recommended to the user is fully operational. Furthermore, the icons 40 are listed
according to the relevancy of the applications, the most relevant starting at the top of
the screen 8. The user is then able to execute a specific application by activating the
associated icon within the GUI of the mobile phone 7.
However, the GUI may present the recommended applications to the user by
any other way in a sense that allows the user to understand which applications are
the most relevant. For instance, the GUI may highlight the recommended application
in a list comprising all the application of the mobile phone.
The applications comprise traditional applications and World of Things
(WoT) applications.
The traditional applications may be executed anywhere as they do not need
connected resources, which availability depends on the user's 25 environment. For
instance, a traditional application may consist in a weather forecast application 4 1
which shows the weather forecast as a function of the position of the mobile phone 7.
To this end, the weather forecast application 4 1 needs the position of the mobile
phone 7, which is provided by a geo-localization module in the mobile phone 7 and
a weather information feed. The weather information feed is provided by a distant
server 5 and is always accessible to the mobile phone 7 as long as it is connected to
the network 2 whatever the environment of the user 7 is.
The user environment is determined by the location of the mobile phone 7.
The location is identified as a function of the latitude and longitude coordinates
indicated by a GPS receiver associated to the mobile phone 7. However, the location
may also be defined by another type of localization such as a logical reference to a
place where the user can be localized. Such localization to a place can be implicit or
explicit.
An implicit localization may be, for instance, provided by associating a
specific logical localization reference to a cell, e.g. a femtocell comprised in a
wireless network. A femtocell is a small cellular base station connected to the network
and able to support active mobile phone connections in a certain range. When the
mobile phone is connected to this specific femtocell, which means the mobile phone
7 is the said range of the femtocell, the location data is set to the logical reference
associated to the femtocell.
An explicit localization could consist in the user 25 running a localization
application. In this application, the user 25 indicates on a map where he is currently
localized.
The logical reference may be for instance "at home" or "at the office".
In contrast to the traditional application, in order to fulfill their tasks, the
WoT applications use resources which may or may not be available depending on the
position of the mobile phone 7. More precisely, the WoT applications use connected
resources corresponding to physical objects, each associated to a specific location. If
the mobile phone 7 is too far from a physical object, the associated resource is not
available for the WoT applications and therefore the WoT applications are not able to
operate if no other resource is available to replace the unavailable resource.
In the network illustrated in figure 1, the lamp 1 and the screen 6
correspond to physical objects present at the user's 25 home and therefore are
encircled by the doted circle 32. The printers 3 and 4 correspond to resources
provided by physical objects at the user's 25 workplace. The workplace is represented
in figure 1 by the continuous encirclement 33.
An example of a WoT application is a Train Warning application. When the
Train Warning application is launched by the user 25, it informs the user 25 when a
train is approaching a specific train station. In order to inform the user 25, the
application controls a connected resource 1, which is a physical object in the user
environment and comprises a visual device to have it blink when a train is going to
arrive at the train station in less than 5 minutes.
For that purpose, the Train Warning application needs two resources. The
first resource is a traffic information feed. The traffic feed consists in a data stream
comprising information about the train traffic provided by a distant server 5. The
second resource required is a physical object which comprises a blinking service. This
service may be provided, for instance, by the lamp 5 thanks to an internal module in
the lamp 5 that can be activated to make the lamp blink. The internal module
typically comprises a control switch and a communication interface to receive control
instruction trough a wired or wireless link.
However, if no lamp 5 or other connected resource can provide the service
of blinking in the user environment, the Train Warning application cannot fulfill its
task. Therefore, the application would not be operational.
As some applications may not be operational depending on the user
environment, the GUI of the mobile phone 7 recommends and displays to the user
25 only applications which can fulfill their task. More precisely, the GUI displays a
selection of icons in which each icon corresponds to an operational application.
Moreover, the icons are displayed in an order corresponding to their relevancy.
This aspect is illustrated in figures 3 to 5. Figure 3 corresponds to a GUI
which displays the application icons 4 1, 42, 43 whatever the operational or non
operational status of application. Therefore, all above mentioned applications and
further a printer application are displayed by the respective icons 4 1, 42, 43. The
printer application is an application using the services of any local printer.
Figure 4 and 5 illustrate the displayed application icons when the GUI
displays only applications which can fulfill their tasks. More precisely, in figure 4, the
user is at home and therefore a lamp 5 is available for the train warning application.
Therefore, this application icon 40 is displayed contrarily to the printer application for
which no local printer is available at the user's home.
In figure 5, the user is at his workplace. Therefore the two printers 3 and 4
are available contrarily to the lamp 5. Therefore, two printer application icons 44 and
45 are displayed and correspond each to the printer application respectively
associated to the resources of the first printer 3 and the second printer 4 .
Moreover, as the weather application is always available, the GUI illustrated
on figures 4 and 5 display the weather forecast application icons 4 1 as well.
For the purpose of displaying to the user 25 only applications which can
fulfill their task, the mobile phone 7 comprises a recommendation engine 11 and a
WoT recommendation module 12 which determine and provide to the GUI the
operational applications and the relevancy of the operational applications.
The functioning of the recommendation engine 11 and the WoT
recommendation module 12 will now be described in reference to figure 2.
When the user uses the mobile phone 7, the recommendation engine 11
accesses to context data 10 stored in the mobile phone 7. Context data could
comprise the position of the mobile phone 7, the time, the current activity of the user
and the planning of the user 25.
The recommendation engine 11 accesses a database of applications 13 in
the data storage of the mobile phone 7 and selects applications 15 to be
recommended among this database according to the context data. For instance, if
the GPS coordinates correspond to the user's home, applications relating to leisure
will be most likely selected. If the GPS coordinates of the mobile phone 7 correspond
to the user's workplace, applications related to his work such as "employees
Directory", "Meeting reservation", "Printer" applications will be most likely selected.
For that purpose, the mobile phone comprises predefined user contexts such as "at
home", "at office" which are associated to a set of applications and a specific range
of GPS coordinates. Other kinds of predefined user contexts may be used. For
instance, predefined contexts such as the city in which the user is located may be
used: "in Paris", or "in New York". Other types of contexts may be used or combined
with the location context. For instance a time context may be taken into account to
determine the relevancy of the application and may comprise "in the morning", "at
lunch time", "in the evening". When different types of context are taken into account
in the determination of the relevancy, the different types of contexts may be balanced
with weighting coefficients.
The selected applications are stored in a first list of applications, and the
recommendation engine 11 provides the first list of applications 14 to the WoT
recommendation module 12. Furthermore, the WoT recommendation module 12
accesses to the context data in order to get the location of the mobile phone 7.
With the location of the mobile phone 7 and the first list of application, the
WoT recommendation module 12 selects the applications 15 which are operational.
For that purpose, an application analyzer 16 analyses the applications of the
first list and determines the services required for each application in order to fulfill its
task.
To that end, the database 13 provided in the data storage comprises a
semantic description of each application in which the properties of the respective
application are identified. An XML semantic description of the above mentioned Train
Warning application is shown below in appendix 1.
In this semantic description, "Haslnput" tags identify the resources required
by the Train Warning application. More precisely, the first "Haslnput" tag indicates
that the application needs a traffic feed "WoT_connected_traffic_feed", and the
second "Haslnput" tag indicates that the application requires a physical visual
connected resource in the user environment that comprises a service for blinking. The
service is identified by the "hasService" tag.
By identifying the tags, the application analyzer 16 determines the services
required by each application in order to be operational and which need to be
supported by physical resource in the user environment. The application analyzer 16
then generates a list of the required services for each application of the first list. The
list of required services is sent 17 to a resources checker 15.
The Wot recommendation module 12 further comprises a Resource getting
module 18. At the same time as the application analysis 16, the resources getting
module 18 sends the coordinates 19 of the mobile phone 7 and an user identifier to
an external WoT framework module 20 running in the framework 30. The user
identifier may consist in an identifier associated to the mobile phone 7, login data
that the user has entered on the mobile phone or any other information that may
identify the user or the mobile phone 7.
The WoT framework module 20 generates a list of all available resources in
the user environment according to the coordinates and the user identifier transmitted
by the resources getting module 18 and transmit it to the resource getting module 18.
To this end the Wot Framework 20 comprises a list of the connected
resources in the network 2. The connected resources are associated to spaces. The
two printers 3 and 4 are associated to a workplace space 33, and the lamp 5 and the
screen 6 are associated to a home space 32. When the mobile phone 7 sends
coordinates 19 to the WoT framework 20, the WoT framework 20 determines if the
sent coordinates correspond to a range of coordinates associated to one of the
spaces 32 or 33.
When the mobile phone 7 sends coordinates corresponding to the user
home, the WoT framework sends back 2 1 a list of available resources comprising a
semantic description of the lamp 5 and a semantic description of the screen 6. In the
same manner, if the mobile phone 7 sends coordinates corresponding to the
workplace, the WoT frameworks sends back the semantic description of the two
printers 3 and 4 .
An example of WoT framework module is described in "Providing User
Support in Web of things enabled smart spaces" BOUSSARD, M. in Proceedings of
Second International Workshop on Web of Things (WoT Ί 1) . ACM, New York.
Afterwards, the resource getting module 18 forwards 22 the list of semantic
description to the resources checker 15.
The semantic description of a resource describes the service provided by the
said resource as well as additional data such as information about the owner, the
location of the connected resource, the state and the usability of the connected
resource. The state indicates the real operational state of the resource which informs
if the resource is currently available. The state can be set to "operational", "busy" or
"out of order". Furthermore, the usability defines whether the resource is shared or
not. Therefore, the usability can be set to "public" so as to allow every user to access
the resource, "community" so as to only allow users among a predetermined list of
user or "private", which means only the owner has the access to the resource.
Therefore, in the step 2 1 of sending the semantic description of the available
resources, resources owned by the user as well as resources owned by other people
are sent to the user.
The WoT framework may further determine the list of available resources as
a function of the user identifier. For instance, the WoT framework compares the
usability and ownership information of the resources to the user identifier. The WoT
fra mework then sends a list com prising only private resources owned by the user,
public resources, and com munity resources for which the user is included in the
predetermined list.
An exam ple of a semantic description is shown below and consists in the
sema ntic description of the lam p 5.
In this semantic description, the services, which can be provided by the lam p
5, are identified by the "hasService" tags. The lam p can provide two services, which
are the switching the lam p on or off, or make the blinking of the lam p 5. The
additional information are identified by "owner", "state", "usability" and "location"
tags and are respectively set to "ownerldentity", "Operational", "Public" and a GPS
coordinate x,y.
In the same way as the location determination of the mobile phone 7
explained above, the location of the resource may also be determined by a logical
reference explicitly by the user or implicitly.
The application checker 15 analyses the list of available resources and
com pares the list of required services sent by the application analyzer 16 with the list
of available resources provided by the resource getting module 18. More precisely,
for each application of the list of required service, the application checker 15 verifies
whether each of the required services of the said application has a match in the
services provided by the resources of the list of available resources. Furthermore, the
application checker verifies if the resource has an operational state in order to
consider it as a matching resou rce. The application checker 15 generates a list of
operational applications for which the application checker 15 finds a match for each
of the required resources of the said application .
A matching service in the list of available resources may be obtained by a
direct matching or a com posite matching .
A direct matching means that a requested service can be supported by a
service of one of the physical resources of the list of available resources. Therefore,
there is an exact matching between the service requested and the available service.
A com posite matching means that the required service can be supported by
a combination of services of more than one available physical resource.
Therefore, the application checker 15 may determine n resources in order to
provide m required services. Some of the m required services may be provided with
direct matching and the other of the m required services may be provided with by
composite matching services of the available resources.
The application checker 15 sends the list of operational application 16 to a
ranking modu le 24.
The ranking module 24 calcu lates the relevancy score for each application
of the list of operational applications, and establishes a ranked list of operational
applications according to their respective calculated relevancy scores.
To this end, the Wot recom mendation module 12 com prises a preference
module 27. The preference module 27 contains user's preference rules, which are
stored in a database of the mobile phone 7. The preference rules are provisioned 28
by the user 25 and represent the preference of the user 25 on certain value of the
properties of the available resources. The user rules concern the proximity of the
resource, the ownership of the resource and therefore indicate if the user 25 prefers
the resources owned by himself or his com pa ny to resources owned by third parties,
or if the user 25 prefers the resources which are the closest to the mobile phone 7.
The ranki ng module 24 accesses to the user's rules and calculates a
relevancy score for each application of the list of operational applications according
to the user's rules. For instance, if the user is at his workplace, an operational
application would be a "Print" application which requires a printer. The semantic
description of each of the printers comprises their GPS coordinates. Therefore, the
ranking module 24 determines a higher relevancy score for the Print application
associated to the closest printer than to the print application associated to the other
pri nter. Turning back to figure 5, the first printer 3 is closer to the user than the
second printer 4 . In consequence, the printer application associated to the first printer
3 gets a higher score than the printer application associated to the second printer 4 .
Therefore, the icon representing the printer application associate the first printer 3 is
displayed at the top of the screen 8. Moreover the ranking module 24 calculates the
releva ncy score of the applications as a function of the type of matching which was
determined by the application checker 15 for a specific application . For instance, an
application, operational thanks to a direct matching, gets a higher relevancy score
than the same operational application obtained by a com posite matching of services.
The resulting ranked list is transmitted 29 to the GUI, which displays icons
according to the ranked list.
Therefore, the GUI only displays icons of applications which may fulfill their
tasks. Moreover, the icons are listed according to their relevance calculated on the
base of information about the resources which would be executed with the
application but also on the base of the user context.
In other embodiments of the invention, the ranked list may be transmitted to
a voice speech interface or any means that may propose to the end user the
recommended operational applications, or another application that will process the
ranked list, instead of a GUI.
Moreover, the method according to the invention may operate on any other
computing device connected to the internet such as a, for instance, a smartphone, a
computer or a tablet computer.
The methods described hereinabove may be executed through the use of
dedicated hardware as well as hardware capable of executing software in association
with appropriate software. When provided by a processor, the corresponding
functions may be provided by a single dedicated processor, by a single shared
processor, or by a plurality of individual processors, some of which may be shared.
Moreover, explicit use of the term "processor" should not be construed to refer
exclusively to hardware capable of executing software, and may implicitly include,
without limitation, digital signal processor (DSP) hardware, network processor,
application specific integrated circuit (ASIC), field programmable gate array (FPGA),
