The technical field to which the invention relates.

The present invention relates to an information system, which provided the opportunity to interact with the user by using the identification system.

The level of technology

Recognition systems typically contain two modules: a recognition module, which converts the phrase spoken by the user in the text computer representation, and the module generate text, which converts text computer representation in sounding phrases that are understood by the user. There is recognition system, called speech recognition systems, where the user can say phrases, and such systems can generate sounding phrase for the user, and the text recognition system, such as system scanning text, using which the user can generate phrases in written text, and such systems can generate phrases for the user in writing.

Information systems control the information that is usually contained in the databases. These databases are usually customized to suit the specific needs of users, as well as taking into account features of information systems intended to be used for the specified database.

In databases, Dan is haunted, also called objects, are grouped into types of objects identified by a specific code. Each object type consists of instances of the object, that is, the specific data or objects, of the type in question. Each object type is associated a certain number of attributes that characterize the object instances of this type. Similarly, objects, attributes can be combined in the types of attributes. The types of attributes are attributes that have similar characteristics, such as text attributes or attribute data.

Each information system adapted to the databases, which it must operate and, thus, can access the object types, attribute types and object instances of the object type with specific instances of attributes. Therefore, the codes used in the database to identify object types and attribute types are recognized information system, which should be managed by the specified database.

In addition, each information system contains the types of actions that combines the actions that can be applied to database objects using the system. Each type of action suited to one or more object types.

Information systems linked by a variety of applications, for example, Geog officesa information system (GIS (GIS)), system enterprise resource Planning (ERP (ERP), document Management system (UD (DM)) or product data Management (UDP (PDM)and other well-known applications commercial applications.

Traditionally users certain information systems interact with it using the interface, specially designed for this system, which is different in different systems, even in the same scope. In addition, the specified user must interact with the information system, using the keyboard and/or mouse of the computer from which you are accessing the information system. The present invention solves these problems by using a system of interaction, called the language of the voice query, which allows the user to interact with existing information systems for various applications, by leveraging the existing recognition systems. The present invention thus allows the user with voice phrases, called queries, to include the actions defined information system in relation to the objects recorded in the databases managed by the information system and identified using attributes.

The inventor has found that for all info is information systems applications can be defined by the common object classes, attribute classes and classes of actions. These classes are, respectively, combine objects, attributes, and actions that have a common characteristic that defines the considered class, with the specified feature is specific to all information systems applications. The same object instance can have multiple classes of objects, if it simultaneously possesses the characteristics of these different classes. On the basis of specified classes of objects, classes, attributes, and classes of actions can be defined installation phrases, actions, components of models, which can be associated with a particular object types, attribute types and action types defined information system under consideration of the scope and object instances with instances of the attributes recorded in a database managed by using the information system. Said installation phrases actions that are used to build the actual phrases, and, thus, to define a grammar consisting essentially of object types, attribute types, action types and rules education, necessary for the organization of user interaction with the information system of the considered applications, as in the cases when the system offers the user various options which of the requests, he can enter into the system and when the user enters the query into the information system.

Brief description of drawings

The present invention will be described in detail below with reference to the drawing, which shows the interaction system in accordance with the present invention, integrated into the environment.

Detailed description of the invention

As shown in the drawing, environment, containing interaction system in accordance with the present invention, consists of the following elements.

1. An information system for managing multiple types of objects, characterized by several attributes, which are part of the attribute types, and control is performed using several types of actions. Object types and attribute types have instances that can be stored in databases that are managed by this information system.

2. Recognition system that contains two modules:

2A. the recognition module, which converts the phrase received from the user computer text representation.

2b. module generate text, which converts text computer representation in the generated phrases that are understandable to the user.

3. System analyst and linguist, forming classes of objects, attributes, and actions, the installation phrases which will be used to perform actions information system object types. System analysts and linguists are people who can analyze the order of the voice user interaction with the system. The result of this analysis should provide a range of facilities phrases, relevant actions that are typical for this application.

4. The user who will use the system using the grammar defined by installations phrases that are associated with instances of objects, attributes, and actions, managed information system.

5. The interaction system in accordance with the invention, allowing the user to interact with the information system when generating phrases, which must have the specified system, based on the above associated installations phrase. This system consists of three modules:

5b. Converter module, which allows you to convert the grammar of the language, which is a set of object types, action types, and rules for the formation of acceptable phrases that may be received from the user in order to interact with the information system, computer representation, which can be used by the recognition system, and converts the computer is predstavleniya, the resulting recognition phrase defined by this grammar. The specified Converter module includes an element C1, which contains information that allows you to configure the recognition system, namely:

- used recognition software,

- used language,

- used data-transfer devices, such as microphones or telephones.

5A. The module scope, which allows you to get items such as object types, attribute types and action types, and instances of the latter, which are operated information system pre-defined applications. Module application contains definitions of classes of objects, actions and attributes that are typical for the specified field of application, and which are used to map obtained above elements, with the above settings phrases actions, to determine the grammar required for a typical module 5b. Installation phrases actions receive from system analyst and linguist, to enable generation of user queries using natural language. If at the same time there are many information systems, can be generated and activated many grammars. The system of interaction, which according to the present invention, will switch between different information systems. A similar switch may be installed between the interaction system in accordance with the present invention for applications such as GIS, and the interaction system in accordance with the present invention for other applications, such as UD. Module applications can also be phrases generated by the Converter module after recognition, and generate a description of the actions on these objects identified by using specific values of attributes for performance information system 1. The above definitions are contained in item C2 module scope, which contains:

Information common to several applications, such as General concepts about the objects and attributes that identify the objects.

- Identification of the application that contains configuration elements that identify the scope of information systems, such as, for example, the information system GIS.

- Object classes belonging to this application area. Each class represents a set of objects with common characteristics. For example, in GIS applications there are classes of objects, as a class a surface (of the state, administrative district), Lina the major classes (rivers, street), point classes (city), graphics classes (aerial photography with geographic references, maps). The real object may be a part of several classes of objects. For example, in the field of GIS applications typical object, such as a city street, will belong to the class of the displayed object, the class of the selected object, the feature class and the class of linear object.

Classes of actions that can be applied to classes of objects. Undoubtedly, with each class of objects, you can define interconnected for this application class actions that can be applied to the specified object class. For example, in the application of GIS object belonging to the displayed object class that can be displayed or can be hidden, the object belonging to the class of spatial object can be projected on a map or may overlap with another object belonging to the same class, the object that belongs to the selected class of objects can be selected, or the selection may be cancelled, object belonging to the class of linear object can move along a certain distance to determine the specific location. Regardless of the types and instances of a particular object, it is always possible to manage (display, choose, provided the line...) point, line and surface objects contained in another surface of the object, to manage surface objects that cross the line features or control point objects along a specified line object.

Classes attribute that can be attached to objects. The attribute class combines attributes with a total value in relation to the objects of all object classes. Namely, the attributes belonging to the class names of the instances that are used to identify a specific instance of the object type. For example, in the field of application of GIS roads have the attribute "number of the road, copies of which represents a specific number. The attribute "number of the road", therefore, represents a type of "digital"attribute, but also part of a class attribute of "instance name", because the reference to the road when the speech request can be made using a number of roads.

- Various settings phrases can be used to implement the request to perform the action. Every class action can determine the associated installation phrases that can be used to make a request for execution of the action class. For example, in the field of application of GIS can be defined such phrases as to display "xyz" or switch to "abc". As "xyz" or "abc" COI the box is used the class attribute to identify the types of objects which action will be performed, they can be referenced. These settings will be mapped to instances of objects belonging to these types of managed information system, which should interact with the user. In addition, actions such as "show" or "go", can have synonyms, which can easily be replaced with the original terms. This means that many variations of the same plants phrase can exist without significant changes in the grammatical structure.

Elements of terms, which are collected in sequence, make up phrases, generated by the user. There are elements of static terms, the instances are not required to select from the information system, such as numbers, comparison operators, and dynamic elements, copies of which really should be selected from the information system, such as object type or attribute types. Elements of the terms defined statically, represent a direct list of terms whose elements can be pre-defined when configuring the module scope.

Each of these elements can be identified using a flag as optional; this means that these elements can be predicted when generating, and it will not affect C is Uchenie phrase, for example, expressions of politeness.

Each of these elements can also be identified using a flag as a duplicate, for example, to compile digital values, codes for the identification of spelling or pointing geographical location.

For example, in the application of GIS can have the following sequence of elements of static terms: [-1] [2] [+3] [-4], where [-1] denotes an optional list of terms consisting of such terms as "please" and "could You", [2] refers to the list of mandatory terms, consisting of "scrolling information on the display screen" or "go to", [+3] denotes a list of recurring terms, consisting of the terms "North", "East", "West", "South", [-4] denotes an optional list of terms consisting of such terms as "please". Thus, on the basis of these elements can be built following acceptable phrases: scroll on the North-East, were would You go South, South-East, please.

Can also be built phrases such as [1] [2] [3] and[1] [4] [3] [5] [2], in which [1] is "show"or "display", [2] represents the name of the instance of the corresponding object, [3] is the name of a feature type [4] means "this" (the definite article "the"), [5] indicates genitive (in English opredelaetsa the preposition "of"). Elements [2] and [3] are elements of the dynamic terms. Then, if the dynamic elements selected from the information system, represent the two-dimensional object, called the city and state, and titles of the two instances represent new York and Washington for the city and new York and Idaho state, resulting in the generation of the combination will be obtained the following phrases:

[1] [2A] [3A]

[1] [2b] [3b]

[1] [4] [3A] [5] [2A]

[1] [4] [3b] [5] [3b],

in which

[2A] will be a new York or Washington

[3A] will represent the city

[2b] will represent new York or Idaho

[3b] will represent the state,

the result can be a specific phrase, such as "show the city of new York" or "reflect Idaho.

5s. the interface module of the information system, which is designed for a specific application of the information system. This interface module is designed for extraction of object types, attribute types and action types and their instances from the corresponding information systems and to transfer them to the module 5A applications, where they are linked to classes of objects, classes, attributes, and classes of actions that define the scope of the information system. On the other hand, the specified interface module allows you to ensure that work is information systems so she could run a query on the action contained in the phrase received from the user. This requires that the interface module translated description of the actions provided by the module 5A applications in the application logic of the information system.

The transfer of information between the different elements defined above, the environment, as follows:

From 5b in 2A: list of words and definitions of education regulations governing the combination of these words, in an acceptable phrase in computer performance that meets the recognition system.

From 2A to 5b: the recognized phrase in the computer representation corresponds to the recognition system. This phrase corresponds to the acceptable word sequences.

From 5b 2b: text computer representation, which is read aloud to the user.

- From 5A to 5b: the set of lists of terms and a set of rules for combining, using lists of terms for building installations phrases that are acceptable phrases that can be obtained from the user.

From 5b to 5A: the phrase received from the user is parsed to identify the rules of combination, and the identification of appropriate lists of terms and list of terms received from the user.

From 5C to 5A: list of object types with their matched with the existing types of classes instances of objects, types of attributes with corresponding instances of classes and attributes.

- From 5A to 5C: action with the appropriate parameters, sung by the information system.

These parameters can include instances of object and attribute. In doubtful cases, when access to two different actions, or two different objects can be done using the same user command, the module application returns information system various possibilities, in the hope that the adapter module will eliminate the ambiguity by using the context information of the information system or performing a reverse query to the user.

- From 1 to 5C: similarly, from 5C to 5A, but using a logical language 1, and thus, depending on 1.

From 5C in 1: similarly, from 5A to 5C, but with a translation into the logical language 1, and thus, depending on 1.

The use of the system of interaction in accordance with the present invention, involves the following sequence of events:

- Identified the scope, resulting in the realignment of common object classes, attribute classes and class action information system.

System analyst and linguist 3 defines object classes, attribute classes and class of the action and the appropriate installation phrases actions required in the scope.

- Information is encoded into an internal format that is used by the module 5A applications.

For specific information system 1 is determined by the module 5C pair, which belongs to the identified application.

- 4 user begins operation of the information system.

Information system starts the operation of the interface module.

The interface module uses the information system to select objects that can be used by the user and passes this information to the module scope.

Module application uses object classes, attribute classes and set phrases the steps above to build lists of terms and rules of combination for the standard module 5b.

- Converting module converts lists of terms and rules of combination, in a form acceptable to the recognition system, and begins her work.

- The user submits the phrase.

System 2 recognition after recognition of an acceptable phrase returns the recognized phrase in the Converter module.

- Converting module performs inverse analysis of phrases in the rule of combination, and a list of terms and transmits them back to the module scope.

Module application transmits a need for the needful information to the interface module to perform the action.

The interface module then makes a request of an information system to perform the action.

Example of classification of information processed by the system of interaction, in accordance with the present invention, allowing the user to interact with the information system applications of GIS.

Has an information system that allows you to display or to select features according to the respective values or spatial dependencies.

With this system of interrelated types of objects that represent the country and the city; the object instances of these object types have two associated attributes that represent the names and population. The name represents the type of text attribute, the population is a type of digital attribute.

Countries have two instances: the U.S. and France.

Consequently, their population is 250000000 and 60000000 people.

For cities, there are six instances: new York, Los Angeles, Dallas, Paris, Lyon, Marseille.

Their population respectively is 12000000, 10000000, 500000, 6000000, 1000000, 800000 inhabitants.

In English you can define the following phrases to provide access to these objects through the system:

Typical class operation display/hide:

To display the country

Hide the display of countries

To display the city

Hide the display of cities

Operation Global selection:

To select all countries

Select all of the city

The operation of the select attribute by name

Choose a country called France

Select a city called Los Angeles

The condition expression of an attribute:
