Description
BACKGROUND

The present invention relates to an embodiment of a method, apparatus, and system for identifying events, and more particularly, but not by way of limitation, relates to a method, apparatus, and system for identifying and explaining life events that may impact outcome plans.


Care professionals need to quickly and accurately find what happened in a case (e.g., since the last appointment or review with an individual). However, the high volume of information, which is often buried in unstructured case notes written by several care professionals working in the same team, makes it easy to overlook changes and events that may impact an outcome plan or individual plan. Such data is difficult to sort through. This is even more critical for vulnerable individuals receiving multiple services. Outcome management has an essential role in assisting an individual to achieve their goal such as remedying a health issue or other outcomes. Outcome management can also be applied in a variety other fields.


Therefore, there is a need to have techniques that can efficiently identify and explain events that may impact outcome plans. There is a need for a technical advancement in machine learning within a computer management system that can rapidly process the large amount of information in question that is difficult to process in a short amount of time.

DETAILED DESCRIPTION

The following detailed description is merely illustrative and is not intended to limit embodiments and/or application or uses of embodiments. Furthermore, there is no intention to be bound by any expressed or implied information presented in the preceding Background or Summary sections, or in the Detailed Description section.


One or more embodiments will now be described with reference to the drawing figures, 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. Moreover, please note that any of the steps can be performed in different sequences or combined or at the same time. In addition, any of structures and embodiments shown can be modified or combined.


Outcome plans are basically personalized care plans that can provide optimal outcomes for citizens. The citizen engagement process in social care typically starts by identifying needs and strengths, assessing risks and priorities to create an outcome-driven care plan, and it ends with monitoring the plan and evaluating outcomes.


A typical plan contains, for example, goals, notes, actions and associated care activities, progress and results towards an outcome. This data may be either structured or unstructured and is managed by software products such as IBM SPM (Social Program Management), which help care professionals to define and manage outcome plans for individuals. Outcome Management plays a role in assisting a client to achieve their goal. The software can be used to construct an outcome plan to identify and address client needs. These software products typically collect also standard information about an individual, such as age, gender, etc.


A care professional or other type of user can implement an embodiment of the invention. A care professional can define or manage an outcome plan for an individual, where such individual can also be referred to as a “citizen” or “patient”.


An outcome refers to the individual changes in attitudes, behaviours, knowledge, skills, or status resulting from program activities. Example of outcomes can be, for example, smoke cessation, return to work, etc.


Life events can be defined as, for example, discrete experiences that may cause qualitative and quantitative changes and/or readjustments in the life of an individual. Examples of life events can include, for example, marriage, divorce, illness or injury, changing or losing a job, death of family members, birth of child.


Care professionals typically record (some) life events of an individual in her or his care plan. Life events occurring in the household, family or the social context and network of an individual may have positive or adverse impacts in the progress and outcomes of a care plan.


Care professionals need to quickly and accurately find what happened in a case (e.g., since the last appointment or review with an individual). However, the high volume of information (often buried in unstructured case notes written by several care professionals working in the same team) makes it easy to overlook changes and events that may impact an outcome plan. This issue is even more critical for vulnerable individuals receiving multiple services.


An embodiment of the invention helps care professionals using care management software solutions (such as IBM SPM) by identifying life events that may have a possible impact for positive/adverse outcomes in the individual plans.


An embodiment of the invention helps care professionals using care management software solutions (such as IBM SPM) by explaining how and/or why the identified life events are possibly connected to the outcomes in the individual plans. The use by a health care professional is only a non-limiting example. The embodiments of the invention can be applied to any type of technical field and any type of event can be processed as further detailed below.



FIG. 1 illustrates a non-limiting example method to identify and explain events that may impact outcome plans, in accordance with one or more embodiments described herein.


Different from existing clinical early warning systems, an embodiment of the invention identifies relevant life events that may have positive and/or adverse effects in an outcome plan while providing suitable explanations.


In an embodiment, a system can perform the following. Input of information can be provided to a system from a user or another machine, or via a network, etc. 2. The user can be, for example, a care professional (e.g., providing information from case notes). The care professional is a non-limiting example. Other type of users can be entering the information, including, for example, corporate users, corporate management, military, individuals at home, etc. Information from case notes is also a non-limiting example. The information can be obtained by a user or machine from a history log, database, etc.


The system performs extracting and/or identifying facts describing a life events from the input of information 2, such as data entered by care professionals (e.g., from case notes) or other input in block 10. The system can performs extracting and/or identifying facts describing other types of events from the input of information 2



FIG. 2 illustrates non-limiting example of factual relationships, in accordance with one or more embodiments described herein.


The system then executes a process for computing and/or predicting whether there are new (i.e., not already considered in the care plan) factual relationships (i.e., connections) between such facts and the outcomes of the plan 20.


The factual relationships can be based on semantics 50, causality 52, evidence extracted from historical data 54, or various other criteria 56, etc.


The factual relationships may be arranged in a path 58 or chain 60 that connects a life event to an outcome. The factual relationships may also be arranged in other organized methods 62 that connects a life event to an outcome


Referring back to FIG. 1, the system executes a process for computing and/or predicting whether the factual relationships between the life event and the outcome is positive or adverse 30.


In an embodiment, the system provides a human interpretable explanation of the positive and/or adverse factual relationship between a life event and an outcome 40.



FIG. 3 illustrates a non-limiting example timeline, in accordance with one or more embodiments described herein.


In a non-limiting example, a user or machine adds first data entry about individual or entity A 1at t=day n 102, where n is an integer. The individual can be for example, a patient, an employee, a random individual, etc. The entity can be, for example, a company, another machine, a group of individuals, etc. Instead of a patient, the target can also be an object.


The user or machine then adds a second data entry about individual or entity A at t=day n+1 104. The user or machine then adds a third data entry about individual or entity A at t=day n+2 106.



FIG. 4 illustrates a non-limiting example timeline, in accordance with one or more embodiments described herein.


In a non-liming example, there is an outcome plan for an individual “patient A”. The outcome plan or output program can also be for a “target data object” if applied in a different example. The plan can be also for a corporate entity, object, or a group, etc. The outcome plan for patient A is to provide a (1) a cessation to smoking, and (2) healthy eating.


In the beginning (e.g., time=day 1), the care professional adds note about patient A's situation at work 112 and this information is provided as an input into the system. Patient A is under a lot of pressure to close the quarter achieving the target results. Her results may have impact on her career.


The system, then extracts or identifies the event as a stressful situation at work 122. The system then, based on the inputted information and extracted event, determines a potential adverse effect of failure of smoke cessation 132, and also the potential adverse effect of failure of healthy eating 134.


In the next time period (e.g., time=day 2), the Care professional adds or inputs into the system a note about patient A finding a partner; the partner is a non-smoker 114.


The system then extracts or identifies the event as patient A has a non-smoker partner 124. The system then determines that the potential positive effect is smoke cessation 136. No determination as to healthy eating is made.


Then, in the next time period (e.g., time=day 2), care professional adds note about patient A being pregnant, which is entered into the system at 116. The system then extracts from the input that patient A is pregnant at 126. The system then determines the potential positive effect of Smoke cessation 138 and also the potential positive effect of healthy eating 140.



FIG. 5 illustrates further detail of a non-limiting example timeline, in accordance with one or more embodiments described herein. The system also outputs explanations of the factual relationships as shown in the following example. For example, explanation that “stress may have consequence on smokers, who might smoke more” is outputted by the system at 142 for output smoking cessation 132. The system obtains this fact from data extracted from a first medical knowledge base. The Explanation of “stress may have consequence on eating habits” is a fact extracted from a second medical knowledge base at 144 for output healthy eating at 134.


An explanation of “non-smoking partner may effect behavior of smoking” is a fact extracted from first medical knowledge base 146 for smoking cessation output 136. An explanation of “smoking may not be healthy for pregnancy” is a fact extracted from first medical knowledge base 148 for smoking cessation output at 138. An explanation of “healthy eating is helpful for pregnancy” is a fact extracted from a second medical knowledge base 150 for the healthy eating output 150.



FIG. 6 illustrates a non-limiting example system, in accordance with one or more embodiments described herein.


The system 100 can include the following modules linked by a data access layer 212. Person-centric Data module 202, outcome plans data database 204, domain knowledge database 206 and feedback data database link through the data access layer 212. The feedback data database communicates with the feedback collector component 210. A user (e.g., care professional) or machine 224 can input data into the feedback collector component 210.


The Life Events Detection Component 214, Life Events Classification Component 216, Life Events and Outcomes Relationships Component 218, Ranking Component 220, and Alert and Reporting Component 222 are linked with each other, and linked with the data access layer 212. The Alert and Reporting Component 222 can provide an output to the user and/or machine 224.



FIG. 7 illustrates a non-limiting example detail of the input of the system, in accordance with one or more embodiments described herein.


The input 400 of the system can include the Person Centric Data module 202. The personal centric data module can include structured data 302 (e.g., electronic health records, etc.) and unstructured data 304 (e.g., case notes, text) data. Generally, the structured data 302 is highly organized and formatted so that it's easily searchable in relational databases. On the other hand, the unstructured data 304 has generally no predefined format or organization, making it much more difficult to collect, process, and analyze. The unstructured data, for example, includes all the information a care professional usually collects and review to create a care plan for the individual.


Examples of the unstructured data 304 includes health history (electronic health records), social and behavioral situations, other risk variables or social needs that may influence care (e.g., if the person is homeless), personal details (age, gender, etc.), demographics, family situation and social connections, communities or places where the individual belongs, etc. Individual information from social media (if available) could also be leveraged. Additionally, activities and context of daily living (if available) could also be leveraged. The unstructured data 304 examples can also be entered as structured data 302 if there is a predefined format.


The input 400 also includes Outcome Plans Data module 204 can include, for example, such data that include goals, interventions, care activities and plans, progress, strengths and needs and/or risk factors, notes, etc. The outcome plans data 204 can generally include all the information for the outcome plan. Outcome Plans Data module 204 can be, for example, a database, or a table. The Outcome Plans Data module 204 can also include data in structured 306 and unstructured 308 format.


The input 400 also includes Domain Knowledge database 206 can include data sources (structured data 310 and unstructured data 312) useful to find semantic connections and/or train evidence-based AI (artificial intelligence) models to find relevant life events, their polarity and connections. For example, deprivation indexes, literature or databases on social determinants, positive/adverse life events classifications, social services, encyclopaedia of life events, models and historical data for demographics, household and family/social connections, etc.


The input 400 includes Feedback Data module 208 can include data collected from the team of care professionals who have reviewed previous predictions of our system. The feedback data module 208 may include a quantitative score, for example in the range [0,1], and other information to express the accuracy/usefulness of the predictions. Feedback Data module 208 can also include data in structured 306 and unstructured 308 format.


The input 400 can also include Data Access Layer 212 component works as a data provider for all other components. It essentially provides access to various data sources, including the Person-centric data 202, Outcome plans data 204, Domain Knowledge 206, Feedback Data 208.


Other data sources also be added as these are merely examples. Moreover, the data can be entered through other channels such as an input interface 209 which can receive input from internal or external individual or entity, or machine.



FIG. 8 illustrates a non-limiting example detail of the factual relationships, in accordance with one or more embodiments described herein.


The Outputs can be shown as follows. Factual relationships 416 between life events 402 and the outcomes 404 that are defined in an individual outcome plan, where each factual relationship consists of one or more facts (possibly arranged into a temporal sequence) 414 that potentially connect a life event (or other event) 402 to an outcome 410. A fact 414 is an information item extracted from data about the individual, group, or entity 412. Such data (data of outcome plan 412) can be available in existing care-plan management software solutions, and it can be either structured or unstructured (e.g., text). A polarity score 418, which indicates if the factual relationship between the life event 402 and the outcome 410 is positive or adverse can be included. A human interpretable explanation 420 of the factual relationship can also be included. Confidence scores 422 can also be added.


The factual relationship 416 may include a timestamp t_s 424 indicating when the relationship 416 starts to be valid in time, and a timestamp t_e 424 indicating when the relationship ceases to be valid in time. The system may inform or alert care professionals that monitor and review the execution of the care plan and/or recommend the steps to amend the plan if needed.



FIG. 9 illustrates a non-limiting example detail of the Life Events Detection Component, in accordance with one or more embodiments described herein.


Referring to FIGS. 6 and 9, there is Life Events Detection Component 214. The Life events detection component 214 detects life events. The Life events detection component 214 may extract life events from structured data (for example electronic health records), or from unstructured data (for example care manager notes, and similar documents) 302. The output of the component is a “life event object” 304 or other type of event object, including text describing the event 306. The life event object 304 can also include a set of metadata of the event 308, including tags 310, dates 312, and list of facts surrounding the life event 314, etc. A fact may be a fragment of text, or some set of structured data coming from EHRs (electronic health records) or sensors readings. The component may use a combination of techniques and time-series-analysis techniques.



FIG. 10 illustrates a non-limiting example detail of the Life Events Classification Component, in accordance with one or more embodiments described herein.


The Life Events Classification Component 216 classifies life events into a finite number of classes. The component is able to identify events of the classes “positive events” (which are event having a potentially positive effect on an individual's life or that of a group.) and “adverse events” (which are event having a potentially adverse effect on an individual's life or that of a group) 324.


For example, Life Events Classification Component 216 takes as input a “life event object” 320 and produces as output a “life event class” 324, which is a binary value, where “1” indicates that the life event is adverse, and “0” indicates that the life event is positive.


The Life Events Classification Component 216 may also produce a probability score 326 that indicates the confidence of the classification: for example, <life-event-class=1, probability=0.82>, indicates that the life event is adverse with a probability of 82%.


In an embodiment the Life Events Classification Component 216 uses a classifier 322, trained on historical data. Such classifier 322 may use any technique to classify text. For example, the component 216 may consist of a text classifier using the pre-trained language model.



FIG. 11 illustrates a non-limiting example detail of the Life Events and Outcomes Relationships Component, in accordance with one or more embodiments described herein.


In an embodiment, the Life Events and Outcomes Relationships Component 218 takes as input a “life event object”330, and its corresponding “life event class” 332, and produces as output “factual relationships” 334 between facts surrounding the positive or adverse life event, and Outcomes defined in an outcome plan.


A “factual relationship” includes one or more facts (possibly arranged into a temporal sequence) that potentially connect a life event to an outcome 336. A fact is an information item extracted from data about the individual (or group, or entity). Such data can be available in a care-plan management software, and it can be either structured or unstructured (text). In an embodiment, the Life events and outcomes relationship component 218 can also output a polarity score 338, which indicates if the factual relationship between the life event and the outcome is positive or adverse.


In an embodiment, the Life events and outcomes relationship component 218 can also output a human interpretable explanation of the factual relationship 340. In an embodiment, the Life events and outcomes relationship component 218 can also output a confidence score 342. The “factual relationship” 334 may also include two “timestamps” (start and end) 334. The two “timestamps” 344 indicates when the relationship starts to be valid (start timestamp), and when the relationship ceases to be valid (end timestamp). The end timestamp 344 can be optional. The relationships 334 computed by this Life Events and Outcomes Relationships Component 218 are particularly helpful for life events that have been classified as adverse. However, the Life Events and Outcomes Relationships Component 218 also produces helpful factual relationships 334 also for non-adverse life events.


In an embodiment, a “factual relationship” includes, for example, a “motivation”, and a “score”: The “motivation” is an explanation of why a set of facts, F, related to the life event E is connected to an outcome O in an outcome plan. The motivation may, for example, consist of fragment of text, or a set of tags. The “score” can be, for example, a number (e.g., normalized between 0 and 1) that represents the strength of the connection between F and O. The “factual relationship” may also include two “timestamps” (start and end). The two “timestamps” indicates when the relationship starts to be valid (start timestamp), and when the relationship ceases to be valid (end timestamp). The end timestamp can be optional.



FIG. 12 illustrates a non-limiting example detail of the Life Events and Outcomes Relationships Component, in accordance with one or more embodiments described herein.


In an embodiment, the Life Events and Outcomes Relationships Component 218 works as follows. The Life Events and Outcomes Relationships Component 218 uses named-entity-extraction 350. The Life Events and Outcomes Relationships Component 218 computes a set NEF of Named Entity from a life-event Fact “F” description 352, and a set NEO of Named Entities from Outcome “O” description 354.


The Life Events and Outcomes Relationships Component 218 computes, for example, the Jaccard similarity coefficient “J” of NEF 352 and NEO 354 at 356. If “J” is above a given threshold, then the component outputs a relationship between F and O, where the motivation is given by the intersection of NEF and NEO, and the score is equal to J 360.


The Life Events and Outcomes Relationships Component 218 finds a semantic path and/or semantic relations connecting the named entities surrounding the life event facts, and entities in the outcomes progress and plans 358. Relevant semantic relations can be extracted from domain knowledge (e.g., a causality or side effect relation) 364. BERT (Bidirectional Encoder Representations from Transformers) embeddings can also be used if the domain knowledge data is unstructured 362.



FIG. 13 illustrates a non-limiting example detail of the Life Events and Outcomes Relationships Component, in accordance with one or more embodiments described herein.


In another alternative embodiment, the Life Events and Outcomes Relationships Component may use embeddings computed on a language-model such as BERT 370 to compute vector representations of a fact F from a life event object and an outcome O from a given plan 372. The Life Events and Outcomes Relationships Component 218 may output a relationship between F and O if the corresponding vectors in the embedding space are close enough (threshold-based) given a distance metric 376.



FIG. 14 illustrates a non-limiting example detail of the Ranking Component, Alert and Reporting Component and Alert and Reporting Component, in accordance with one or more embodiments described herein.


The Ranking Component, Alert and Reporting Component 220 is a ranking system, which uses information computed by the Life Events and Outcomes Relationships Component 218 to compute a sorted list of facts corresponding to positive and/or adverse life events having an impact on an individual outcome plan 380.


The Facts with higher impact (and higher confidence score) are ranked higher, that is they appear at the beginning of the list 382. The strength of semantic connections is also considered in the ranking (e.g. direct link vs. indirect links, support/weight from the literature, etc.) 384.


The Alert and Reporting Component 222 generates alerts and report listing the ranked facts (from Ranking Component, Alert and Reporting Component 220) from the corresponding to positive and/or adverse life events and having an impact on a person's outcome plan (together with motivations and scores) 390. The motivation may consist of fragment of text, or a set of tags. The “score” is a number (usually normalized between 0 and 1) that represents the strength of the connection between F (fact) and O (outcome).


The Reports may consist of computer files, such as PDF (portable document format) documents or Web pages, or other formatted computer files 392. The alerts may consist of email or push notification 394 or other type of alert. The Alert and Reporting Component 222 consists also of a User Interface 396 that shows the alert and reports to a User. The user interface 396 can be a display with an input interface, or a mobile device, etc. The user interface 396 can also be a Web-based User Interface.



FIG. 15 illustrates a non-limiting example detail of the User and Feedback Collector Component, in accordance with one or more embodiments described herein.


The User and Feedback Collector Component 222 collects the following information.


The User 224 (which can also be a machine) of the system can be a Subject Matter Expert (SME), such as a care professional, who manages care plans and outcome plans involving a person.


The Feedback Collector Component 224 allows the user 224 to express feedback about the output of the system. In an embodiment, the feedback consists of a integer value (from 1 to 5) which represents a quantitative measure 506 of how much the user agrees with the output of the system, that is how much the user find the output of the system useful/important/correct (5 being very high, and 1 being very low).


In one embodiment, the Feedback Collector Component 222 consists of Web-based User Interface 504. The system may inform or alert care professionals that monitors and review the execution of the care plan and or recommend the steps to amend the plan if needed via the interface 504. Such feedback is potentially used by the system to improve predictive AI (Artificial Intelligence) models and the accuracy of future computations.


Differently from health events, life events are complex and multidisciplinary in nature and therefore difficult to detect. Assessing and checking every time there is a change in circumstances, for an individual and household, whether there is an impact on the risks, vulnerability and/or eligibility to care services, and why, is difficult point due to the vast amount of documentations and notes written by different care professionals.


Care professionals need to quickly and accurately find what happened in a case (e.g., since the last appointment or review with an individual). However, the high volume of information (often buried in unstructured case notes written by several care professionals working in the same team) makes it easy to overlook changes and events that may impact an outcome plan. This is even more critical for vulnerable individuals receiving multiple services. Therefore, integration into a computer system is necessary since the information is of a high volume, time critical, and analysis is needed of the information.


Therefore, care professionals with system of an embodiment can identifying life events that may have a possible impact for positive/adverse outcomes in the individual plans. The system of an embodiment can also explain how, and/or why the identified life events are possibly connected to the outcomes in the individual plans. In an embodiment, the system can be part of an early warning system for care professionals in the social and welfare domain.


In an embodiment, the system can build on top of existing social care systems (such as IBM SPM), however its applicability can be broader than the social care domain. The events can be any type of event. For example, the online advertising industry can implement the system of an embodiment. In such a domain, the outcome of an online advertisement action is to influence the individual buying decision, possibly in a positive way.


In an embodiment, the system can help automated online advertisement by providing an additional signal to the advertisement engine. Such signal can consist of the factual relationships between life events/actions/preferences of an individual (typically available in the individual social media streams), and the individual propension to click on the advertisement or buy the product. The polarity and confidence score provided by our invention may be very useful in this domain.



FIG. 16 illustrates another hardware configuration of the system, where there is an information handling/computer system 1100 in accordance with the present invention and which preferably has at least one processor or central processing unit (CPU) 1110 that can implement the techniques of the invention that can produce as output “factual relationships” between facts surrounding the adverse life event, and outcomes defined in an outcome plan, such that it can process and analyze in a rapid manner the vast amount of data.


The CPUs 1110 are interconnected via a system bus 1112 to a random access memory (RAM) 1114, read-only memory (ROM) 1116, input/output (I/O) adapter 1118 (for connecting peripheral devices such as disk units 1121 and tape drives 1140 to the bus 1112), user interface adapter 1122 (for connecting a keyboard 1124, mouse 1126, speaker 1128, microphone 1132, and/or other user interface device to the bus 1112), a communication adapter 1134 for connecting an information handling system to a data processing network, the Internet, an Intranet, a personal area network (PAN), etc., and a display adapter 1136 for connecting the bus 1112 to a display device 1138 and/or printer 1139 (e.g., a digital printer or the like).


Therefore, for example, in an embodiment as shown above, a component of a computer system, such as the CPU 1110 can take as input a “life event object”, and its corresponding “life event class”, and produces as output “factual relationships” between facts surrounding the adverse life event, and outcomes defined in an outcome plan, such that it can process and analyze in a rapid manner the vast amount of data. The CPU 1110 can analyze the “factual relationship”, which includes, for example, a “motivation”, and a “score”. The “motivation” may consist of fragment of text, or a set of tags that is processed by the CPU 1110. The “score” can be a number (normalized between 0 and 1) that represents the strength of the connection between F and O for processing by the CPU 1110. The “factual relationship” may also include two “timestamps” (start and end) that is analyzed by the CPU 1110. The output from the analysis and machine learning by the CPU 1110 can be displayed on display device 1138 or the information can be sent externally through a network.


In addition to the hardware/software environment described above, a different aspect of the invention includes a computer-implemented method for performing the above method. As an example, this method may be implemented in the particular environment discussed above.


Such a method may be implemented, for example, by operating a computer, as embodied by a digital data processing apparatus, to execute a sequence of machine-readable instructions. These instructions may reside in various types of signal-bearing media.


Thus, this aspect of the present invention is directed to a programmed product, including signal-bearing storage media tangibly embodying a program of machine-readable instructions executable by a digital data processor incorporating the CPU 1110 and hardware above, to perform the method of the invention.


This signal-bearing storage media may include, for example, a RAM contained within the CPU 1110, as represented by the fast-access storage for example.


Alternatively, the instructions may be contained in another signal-bearing storage media 1200, such as a flash memory 1210 or optical storage diskette 1220 (FIG. 27), directly or indirectly accessible by the CPU 1110.


Whether contained in the flash memory 1210, the optical disk 1220, the computer/CPU 1110, or elsewhere, the instructions may be stored on a variety of machine-readable data storage media.


Therefore, the present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.


The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing.

The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
