The present invention relates, generally, to the field of computing, and more particularly to improving Natural Language Processing (NLP) based on a user eye tracking while interacting with graphical user interface (GUI).
NLP is a field of computer science, artificial intelligence, and computational linguistics related to the interactions between computers and human natural languages, such as programming computers to process natural language corpora. A subfield of NLP is natural language understanding that relates to machine reading comprehension and allows for answering a question in a natural language by transferring the question into a computer searchable query. The machine reading comprehension may be achieved by ontology-based data integration. The ontology-based data integration is an effective combination of data from multiple heterogeneous sources that enable the unambiguous identification of elements in heterogeneous information system and assertion of applicable relationships that connect these elements together.
A GUI is a type of user interface that allows a user to interact with an electronic device, such as a computer, through visual indicators presented on a display of the electronic device.
According to one embodiment, a method, computer system, and computer program product for ontology based query suggestion using eye tracking is provided. The present invention may include a computing device receives a query and determines a plurality of implementations based on the query and searching the ontology driven system. The computing device may display the determined plurality of implementations and monitors the eye tracking datum for a fixation. The computing device may determine the corresponding plurality of implementations associated with a region where the fixation is directed based on determining the fixation. The computing device may determine a plurality of candidate elements of the plurality of implementations in the region based on previous determination of the corresponding plurality of implementations. The computing device may generate a plurality of preferred interpretations based on monitoring the eye tracking datum, the corresponding plurality of implementations associated with the region of the fixation, and the plurality of candidate elements.
These and other objects, features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings. The various features of the drawings are not to scale as the illustrations are for clarity in facilitating one skilled in the art in understanding the invention in conjunction with the detailed description. In the drawings:
Detailed embodiments of the claimed structures and methods are disclosed herein; however, it can be understood that the disclosed embodiments are merely illustrative of the claimed structures and methods that may be embodied in various forms. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. In the description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments.
Embodiments of the present invention relate to the field of computing, and more particularly to improving Natural Language Processing (NLP) based on a user eye tracking datum while interacting with a displayed graphical user interface (GUI). The following described exemplary embodiments provide a system, method, and program product to, among other things, improve NLP by dynamically generating query searches based not only on ontology derived interpretations but also on user eye tracking data, such as eye fixations on regions of interest. Therefore, the present embodiment has the capacity to improve the technical field of ontology-based query suggestion by understanding and determining user preferences while the user views the display and determining appropriate query suggestions using ontology and the determined user preferences.
As previously described, NLP is a field of computer science, artificial intelligence, and computational linguistics related to the interactions between computers and human natural languages such as programming computers to process natural language corpora.
Typically, a user may interact with a computing device using voice commands, such as asking questions in a natural language. In order to provide an answer, ontology driven systems may be utilized to determine the answer.
Ontology driven systems are based on “knowledge graph” structures that are stored in the form of searchable databases that include types, properties, and interrelationships of the entities or elements. These elements may be words, phrases, definitions, and acronyms that are typically used for a particular domain of discourse. For example, ATHENA ontology driven system has three different domains (i.e., geographic data, academic data, and financial data). An example embodiment of a structure of financial ontology driven system is depicted in
The ontology driven systems are configured to establish and determine relationships between entities in a question (query) and by using relations between various entities of the database datum, determine various interpretations (suggestions) that may be returned as an output to the query.
Generation of various query interpretations based on ontology driven systems may make determining a correct or user preferred answer without user active intervention in the answer generation process difficult. As such, it may be advantageous to, among other things, implement a system that determines various query suggestions and relevant elements in the ontology driven systems based on an eye tracking datum. The initial query suggestions may be associated with a question asked when the real user intentions are unclear. Presenting the output consisting of various answers to a user in a way that allows for analysis of the eye tracking datum in order to determine a user preferred answer and to dynamically generate additional suggestions based on interpretation that is derived from user fixations without user physical or active interaction. Thus, the method enables the computing device to determine an answer to a question without active user intervention, such as by forcing a user to utilize external devices.
According to one embodiment, the method may determine a plurality of suggested answers based on searching the ontology driven system. Then, the method may display the plurality of suggested answers and analyze the eye tracking datum to determine fixations in regions of interest for the user. The updated corresponding plurality of suggested answers associated with the regions of the fixation based on determining the fixation in the eye tracking datum may be determined. By dynamically determining the candidate elements in the region of interest and updating the preferred interpretations based on monitoring the eye tracking datum, the preferred answers may be generated without the user active intervention in the process of refining of the query suggestions.

The communication network 114 may include various types of communication networks, such as a wide area network (WAN), local area network (LAN), a telecommunication network, a wireless network, a public switched network and/or a satellite network. The communication network 114 may include connections, such as wire, wireless communication links, or fiber optic cables. It may be appreciated that
Client computing device 102 may include a processor 104 and a data storage device 106 that is enabled to host and run a software program 108, an eye tracking datum 120, and a query suggestion program 110A and communicate with the server 112 via the communication network 114, in accordance with one embodiment of the invention. Client computing device 102 may be, for example, a mobile device, a telephone, a personal digital assistant, a netbook, a laptop computer, a tablet computer, a desktop computer, a wearable device capable of executing a code and collecting a user eye tracking datum (i.e. contact lenses, glasses virtual reality glasses) or any type of computing device capable of running a program and accessing a network. As will be discussed with reference to
An eye tracking datum 120 may be a part of a commercially available software component that is configured to control a device or a sensor that measures a rotation of the eyes of a user that is operating client computing device 102 and stores the measurements in a database, such as database 116 or data storage device 106. The rotation of the eyes may be measured, for example, by recording an eye movement with a camera and determining a vector between the pupil center and a corneal reflection. The corneal reflection may be generated by an infrared light. After calibration, the angles and length of the vector may be transformed to a set of coordinates or a region on a display monitor. An eye tracking device may measure the rotation of eyes either optically, electrically, or using eye-attached objects, such as contact lens. According to an example embodiment, eye tracking datum 120 may be configured to record the data generated by the rotation of the eyes when the interpretations are displayed into the eye tracking datum 120, or to a device repository, such as database 116 or data storage device 106).
According to the present embodiment, eye tracking datum 120 may be a software component with an accessible database containing datum that stores eyes fixations of the user on interpretations and interpretation elements that are displayed on display monitor 444. Fixations are periods in which the eyes are motionless while observing a specific GUI element of the interpretation. For example, if the eyes of a user are motionless and the coordinates of the point of gaze fall within the coordinates of a GUI element of one of the interpretations, the user has a fixation on the GUI element of the interpretation. According to an example embodiment, a fixation datum may be used to determine user preferences as to a specific interpretation and a specific element of the interpretation. Fixation may be characterized using three measures: fixation count, total number of fixations on a specific area of the display monitor, and fixation duration. In addition, a total fixation time on a specific area of the display monitor and a first fixation time may be stored and analyzed for determining user preferences. In further embodiments, additional parameters may be stored in eye tracking datum, such as a start time representing a first fixation on one of the interpretations.
The server computer 112 may be a laptop computer, netbook computer, personal computer (PC), a desktop computer, or any programmable electronic device or any network of programmable electronic devices capable of hosting and running a query suggestion program 110B and a database 116 and communicating with the client computing device 102 via the communication network 114, in accordance with embodiments of the invention. As will be discussed with reference to
Database 116 may be a data repository capable of storing information, such as ontology datum 118. Ontology datum 118 may be an ontology driven system software and databases consisting of tables, matrixes, and spreadsheets, and a search engine that allows for submission of queries and receiving an output. As previously mentioned, ontology datum 118 may include words, phrases, definitions, and acronyms that may typically be used for a particular domain of discourse. For example, ontology datum 118 may be an ATHENA ontology driven system that has one of the following domains such as geographical, academic and financial datum. An example embodiment of a part of a financial ontology knowledge tree is depicted in
According to the present embodiment, the query suggestion program 110A, 110B may be a program capable of receiving a natural language query, generating interpretations and determining the preferred interpretation based on eye tracking data. The ontology-based query suggestion method is explained in further detail below with respect to
Referring now to
Next, at 204, the query suggestion program 110A, 110B generates one or more interpretations from the natural language query. According to the present embodiment, the query suggestion program 110A, 110B may convert the natural language input to text using known speech-to-text technology. The converted text may then be used to generate one or more interpretations by an ontology driven system that may be located in an ontology datum 118. According to the present embodiment, each interpretation may be a possible query that represents a natural language question asked by a user in a natural language.
Next, at 206, the query suggestion program 110A, 110B generates an output based on the one or more interpretations. According to the present embodiment, the interpretations may be translated to a domain specific language, such as Structured Query Language (SQL), and searched on the ontology datum 118. An output may be generated by the various query suggestions from the ontology datum 118 that are each a different interpretation of the natural language question asked by a user. For example, if the user asked a question “Show me Xbank Corp. loans” query suggestion program 110A, 110B may generate at least two suggestions where the loans are given or taken by Xbank Corp. An Xbank Corp. may also be interpreted by query suggestion program 110A, 110B as a generic bank or a specific bank and generate additional suggestions.
Next, at 208, the query suggestion program 110A, 110B displays the output on the screen. According to the present embodiment, the query suggestion program 110A, 110B may display the different interpretations on display monitor 444. For example, if the user asked a question “Show me Xbank Corp. loans” the ontology driven system may generate different interpretations due to the fact that it is unclear whether the Xbank Corp. gives loans or receives them. According to the present embodiment, the query suggestion program 110A, 110B may display the output consisting of different interpretations in consecutive order, such as displayed in
Then, at 210, the query suggestion program 110A, 110B determines whether the user is satisfied with the output. According to the present embodiment, a user may acknowledge that the user is satisfied with the output by interacting with an external components 404 of client computing device 102, such as by using keyboard 442 or computer mouse 434. For example, query suggestion program 110A, 110B may present a popup message requesting from a user to either input or “click” with computer mouse 434 that the user is satisfied with the output. In another embodiment, as will be explained in further detail referring to
Next, at 212, query suggestion program 110A, 110B determines user's gaze on the display monitor. According to the present embodiment, the query suggestion program 110A, 110B may access the datum from eye tracking datum 120 and determine the areas where a majority of fixations occurred. For example, the query suggestion program 110A, 110B may convert eye fixation locations on the display to a heat map and identify coordinates where the fixation times or counts are above a threshold value. In another embodiment, the query suggestion program 110A, 110B may identify and flag GUI elements of one or more of the interpretations displayed for future processing.
Then, at 214, the query suggestion program 110A, 110B determines whether there is an interpretation with a highest fixation. According to the present embodiment, the query suggestion program 110A, 110B may compare the counts of fixations and the times of fixations on a display and determine the set of coordinates with the highest fixation times and the highest fixation counts. The query suggestion program 110A, 110B may then determine an interpretation and an interpretation GUI element that is displayed at the same coordinates. For example,
Next, at 216, the query suggestion program 110A, 110B locates the preferred interpretation in the ontology by using the highest fixation region. According to the present embodiment, the query suggestion program 110A, 110B may determine the preferred interpretation by associating a highest fixation region with the interpretation displayed in the region of the display and determines the elements in the ontology that were used for generating the fixated interpretation. Once the query suggestion program 110A, 110B determines the elements used to generate the fixated interpretation, the query suggestion program 110A, 110B may flag the element. To continue our previous example, if the highest fixation of the user is on an interpretation that shows loans given by Xbank Corp. as depicted in
Next, at 218, query suggestion program 110A, 110B determines the candidate elements within the preferred interpretation with high fixation. According to the present embodiment, the query suggestion program 110A, 110B may determine the element that has a highest fixation within the fixated element in order to generate suggested interpretations. To continue our previous example, if a highest fixation is related to a graph element representing the loans given by Xbank Corp. during fiscal year 2013 as depicted at 332 in
Next, at 220, the query suggestion program 110A, 110B generates new interpretations based on the candidate elements. According to the present embodiment, the query suggestion program 110A, 110B may dynamically expand the interpretations that are related to the fixated interpretation and the candidate elements. To continue our example, the query suggestion program 110A, 110B may constantly monitor the eye tracking datum and generate additional interpretations that are related to the fixated interpretation and the candidate elements and also include additional elements related to the fixated interpretation, such as “show total loans given by Xbank Corp. by quarter”, “show borrowers of Xbank Corp. in 2013”, and “show Xbank Corp. loans taken by startups in 2013”.

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.
Characteristics are as follows:
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'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'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.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider'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).
Deployment Models are as follows:
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.
