the invention will now be described with reference to fig1 - 5 , in which like reference numerals refer to like parts throughout . it is emphasized that , according to common practice , the various features of the drawing are not necessarily to scale . on the contrary , the dimensions of the various features can be arbitrarily expanded or reduced for clarity . exemplary embodiments are provided below for illustration purposes and do not limit the claims . with reference now to fig1 , the personalized scheduling and networking system 100 includes a persona detection device 101 , an extraction device 102 , a matching device 103 , a scheduling device 104 , and a notification device 105 . the personalized scheduling and networking system 100 includes a processor 180 and a memory 190 , with the memory 190 storing instructions to cause the processor 180 to execute each device of personalized scheduling and networking system 100 . although the personalized scheduling and networking system 100 includes various devices , it should be noted that a personalized scheduling and networking system can include modules in which the memory 190 stores instructions to cause the processor 180 to execute each module of personalized scheduling and networking system 100 . with the use of these various devices , the personalized scheduling and networking system 100 may act in a more sophisticated and useful fashion , and in a cognitive manner while giving the impression of mental abilities and processes related to knowledge , attention , memory , judgment and evaluation , reasoning , and advanced computation . that is , a system is said to be “ cognitive ” if it possesses macro - scale properties — perception , goal - oriented behavior , learning / memory and action — that characterize systems ( i . e ., humans ) that all agree are cognitive . although as shown in fig3 - 5 and as described later , the computer system / server 12 is exemplarily shown in cloud computing node 10 as a general - purpose computing device which may execute in a layer the personalized scheduling and networking system 100 ( fig5 ), it is noted that the present invention can be implemented outside of the cloud environment . the personal detection device 101 receives user information 150 and creates a user persona for an event that is specific to that particular event . for example , each participant of an event can create an account with social media information ( e . g . an account for twitter ™, facebook ™, a personal homepage , etc .). the persona detection device 101 mines / gathers all of the users information 150 from these sources and creates a user persona profile based on the available information for that user from these sources , as well as from other sources ( e . g ., dblp , google scholar ™, company website ) and extracts keywords , likes or dislikes to create a user persona . the user can also manually enter the user information 150 when registering for an event . the extraction device 102 receives event information 160 and extracts all information pertaining to the types of events , the list of participants , the dates , times , location of events , etc . that is , the extraction device 102 extracts all relevant information in order to create a schedule and network from the event information 160 . the event information 160 includes temporal and spatial information about the event . in this manner , the personalized scheduling and networking system 100 will not attempt to network two users if they are a particular distance apart at the event based on the extracted spatial information by the extraction device 102 . thus , the extraction device 102 extracts all information pertaining to scheduling and networking in order to build a schedule as later described . the event information 160 includes each sub - event having a description ( for example , abstract of talks , full proceedings , or promotional material for a new product ), keywords , time and location in the schedule . the event information 160 further includes a map of the event along with schedules of sub - events , locations of the sub - events , descriptions of the sub - events , schedules of attendees , locations of the attendees , and descriptions of the attendees . that is , schedules are typically online and last - minute updates are posted on the event web - site , vendors typically have links to their web site in the conference online schedule . the extraction device 102 receives the event information 160 and automatically extracts salient features from the sub - event information available from the event website , online material related to the event , and the websites linked to the sub - event page ( s ). also , a user can add an event to the event information 160 . in this manner , once the user signs up for the event , the user has the ability to change the schedule such that all other users will extract the new user - created event using the extraction device 102 . further , the persona detection device 101 creates the user data that is relevant to the specific context based on the event information extracted by the extraction device 102 . thus , there is a feed of data between the persona detection device 101 and extraction device 102 such that a specific context user persona can be created for an event . for example , if a neurosurgeon who likes to sail competitively as a hobby attends a conference and exposition on robotic brain surgery , the persona detection device 101 creates a profile that contains only professional information on the surgeon and does not include information about boating . however , if the same person is attending the us . sailboat show , the user persona will contain little to no professional ( i . e ., directed to him being a neurosurgeon ) information . the matching device 103 matches the user persona profile with events based on the extracted information and the user &# 39 ; s interest . the matching device includes a scoring device 110 that , for each participant , calculates a score for each sub - event , for example based on semantic similarity features derived from the user persona profile and the event information . based on the score calculated by the scoring device 110 , the matching device 103 will match the user with a particular event having the highest score . in this manner , the user will receive an optimized list of matches . based on the matches output from the matching device 103 , the scheduling device 104 creates a schedule for the user for the event . the scheduling device 104 constructs a personalized schedule for the user , using scheduling and optimization techniques , where such schedule will respect explicit user &# 39 ; s directions ( e . g ., the user wants to attend a certain talk ) and will select a subset of events that will maximize the sum of the scores and matches of the matching device 103 and the scoring device 110 subject to the time and location constraints and calculate a schedule and route to attend the set of sub - events and display it to the user . in other words , the scheduling device 104 takes into account temporal and spatial aspects of an event , thereby to create the schedule in addition to the matches and scores . the scheduling device 104 also automatically adapts the schedule based on contingent information . for example , suppose a person wants to visit a certain pavilion at a world expo . the waiting time for visiting that pavilion can vary dramatically , and the scheduling application can dynamically adapt the schedule depending on the current and expected waiting time . thus , the scheduling device 104 generates the schedule in real - time so as to account for last minute changes and abrupt networking opportunities . further , the scheduling device 104 can schedule networking times to network with other users at the event . that is , the scheduling device 104 selects appropriate times to schedule a networking opportunity based on the user &# 39 ; s schedule and on the schedule of candidate participants . for example , the scheduling device 104 detects times that the user can dedicate to networking with limited negative impact to other user &# 39 ; s activities at the event , and match them to similar “ free ” times for other people with whom the user might want to network . the user can input into the scheduling device how to identify networking events scheduled by other participants that might be of interest to the user . in this manner , the scheduling device 104 can prioritize networking over attending an event based on the user &# 39 ; s desires . since the scheduling device 104 accounts for the spatial aspect of the users in the system , even if an event has not been cancelled but a user is presented with a potential networking opportunity ( i . e ., with a second user ) happens to be within a particular distance of the user , the scheduling device 104 can create the networking opportunity . it should be noted that the user can specify to the scheduling device 104 the amount of networking versus attending events that the user would like to do . for example , the user can specify that they would like to network the entire event without attending any of the scheduled events . based on a user &# 39 ; s location , interest and schedule , the notification device 105 will detect other people with similar interests , availability and proximity in locations and propose networking interactions ( i . e ., notify the user of potential events and networking opportunities ). the notification device 105 notifies the user of the networking opportunities in advance as well as how to take advantage of contingent and contextual information to quickly organize networking opportunities . for example , a conference where a paper presentation is cancelled because the author cannot present may be announced at the start of the presentation , and a result of the cancellation might provide a sudden window of opportunity for networking : other people who were interested in attending the talk have matching interests to those of the user , and might be available to networks since the talk is no longer being delivered . the notification device 105 notifies the users of networking opportunities based on a change in the scheduling and networking information such that the user is aware of new networking opportunities causes by last minute changes in the schedule . fig2 shows a high level flow chart for a method 200 for a personalized scheduling and networking method . step 201 receives user information 150 and creates a user persona for an event that is specific to that particular event . step 202 receives event information 160 and extracts all information pertaining to the types of events , the list of participants , the dates , times , location of events , etc . that is , step 202 extracts all relevant information in order to create a schedule and network from the event information 160 step 203 matches the user persona profile with events based on the extracted information and the user &# 39 ; s interest . step 204 calculates a score for each sub - event , for example based on semantic similarity features derived from the user persona profile and the event information . based on the score calculated by step 204 , step 203 will match the user with a particular event having the highest score . step 205 creates a schedule for the user for the event based on the matches output from the matching device 103 . that is , step 205 constructs a personalized schedule for the user , using scheduling and optimization techniques , where such schedule will respect explicit user &# 39 ; s directions ( e . g ., the user wants to attend a certain talk ) and will select a subset of sub - events that will maximize the sum of the scores and matches of step 203 and step 204 subject to the time and location constraints and calculate a schedule and route to attend the set of sub - events and display it to the user . step 206 notifies the user of the networking opportunities in advance as well as how to take advantage of contingent and contextual information to quickly organize networking opportunities . step 206 notifies the users of networking opportunities based on a change in the scheduling and networking information such that the user is aware of new networking opportunities causes by last minute changes in the schedule . it should be noted that the embodiments herein can be implemented on an app for devices which the app can be hosted by the host of the large expo or conference and the attendees can download the app . it is understood in advance that although this disclosure includes a detailed description on cloud computing , implementation of the teachings recited herein are not limited to a cloud computing environment . rather , embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed . cloud computing is a model of service delivery for enabling convenient , on - demand network access to a shared pool of configurable computing resources ( e . g . networks , network bandwidth , servers , processing , memory , storage , applications , virtual machines , and services ) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service . this cloud model may include at least five characteristics , at least three service models , and at least four deployment models . on - demand self - service : a cloud consumer can unilaterally provision computing capabilities , such as server time and network storage , as needed automatically without requiring human interaction with the service &# 39 ; s provider . broad network access : capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms ( e . g ., mobile phones , laptops , and pdas ). resource pooling : the provider &# 39 ; s computing resources are pooled to serve multiple consumers using a multi - tenant model , with different physical and virtual resources dynamically assigned and reassigned according to demand . there is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction ( e . g ., country , state , or datacenter ). rapid elasticity : capabilities can be rapidly and elastically provisioned , in some cases automatically , to quickly scale out and rapidly released to quickly scale in . to the consumer , the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time . measured service : cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service ( e . g ., storage , processing , bandwidth , and active user accounts ). resource usage can be monitored , controlled , and reported providing transparency for both the provider and consumer of the utilized service . software as a service ( saas ): the capability provided to the consumer is to use the provider &# 39 ; s applications running on a cloud infrastructure . the applications are accessible from various client devices through a thin client interface such as a web browser ( e . g ., web - based e - mail ) the consumer does not manage or control the underlying cloud infrastructure including network , servers , operating systems , storage , or even individual application capabilities , with the possible exception of limited user - specific application configuration settings . platform as a service ( paas ): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer - created or acquired applications created using programming languages and tools supported by the provider . the consumer does not manage or control the underlying cloud infrastructure including networks , servers , operating systems , or storage , but has control over the deployed applications and possibly application hosting environment configurations . infrastructure as a service ( iaas ): the capability provided to the consumer is to provision processing , storage , networks , and other fundamental computing resources where the consumer is able to deploy and run arbitrary software , which can include operating systems and applications . the consumer does not manage or control the underlying cloud infrastructure but has control over operating systems , storage , deployed applications , and possibly limited control of select networking components ( e . g ., host firewalls ). private cloud : the cloud infrastructure is operated solely for an organization . it may be managed by the organization or a third party and may exist on - premises or off - premises . community cloud : the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns ( e . g ., mission , security requirements , policy , and compliance considerations ). it may be managed by the organizations or a third party and may exist on - premises or off - premises . public cloud : the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services . hybrid cloud : the cloud infrastructure is a composition of two or more clouds ( private , community , or public ) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability ( e . g ., cloud bursting for load - balancing between clouds ). a cloud computing environment is service oriented with a focus on statelessness , low coupling , modularity , and semantic interoperability . at the heart of cloud computing is an infrastructure comprising a network of interconnected nodes . referring now to fig3 , a schematic of an example of a cloud computing node is shown . cloud computing node 10 is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein . regardless , cloud computing node 10 is capable of being implemented and / or performing any of the functionality set forth hereinabove . in cloud computing node 10 there is a computer system / server 12 , which is operational with numerous other general purpose or special purpose computing system environments or configurations . examples of well -
