 METHOD AND SYSTEM FOR THE PURPOSED PROCESSING OF A MATHEMATICAL EXPRESSION IN AN ELECTRONIC

DOCUMENT

The present invention relates to a method and a system for the purposeful processing of data of a mathematical expression in an electronic text document, in particular with a system for

Identification and identification of a passage in the text after which

Recognizing the mathematical or arithmetic expression of this is characterized in a certain way.

Such methods and systems are known from DE 697 34 400 T2 or

WO 97/049043 has become known in the art. This document discloses a system and method for checking the correctness of the

Spelling words in an electronic document and checking the grammar of sentences covered in this electronic document. In the method, grammatically misspelled words are first extracted from a plurality of sentences, and a grammar checker module is activated that recognizes the misspelled word and then with a Identification module in any way. After marking the misspelled word, the user may issue a signal or command to submit various suggestions and then select a suggestion to be included in the document.

Furthermore, in the prior art, WO 2012/126121 has become known, which is an automatic correction of contact list errors in a

Collaboration system recognizes and identifies. Herein u.a. discloses a search engine that recognizes similarities of a target word and proposes substitute words or expressions using Soundex algorithms that suggest substitute words that sound similar to the target word.

As disadvantageous it is felt in the prior art, that although the

Spell checking in a text document is common in all its facets, and a misspelling is both marked and a marking of the misspelled words is done automatically, but at

Arithmetic operations with mathematical expressions there are currently no such markings, or no test methods that recognize a mathematical expression in a text document and then carries conceivable suggestions both the spelling and the result after bill.

So it is nowadays obvious that when typing a text or e-mails, etc., a spell check is made, usually the erroneous text is marked and then by clicking - generally with the right mouse button - the marked text, a drop-down list with appropriate selectable correction proposals is provided.

Therefore, it is an object of the present invention to provide a system capable of identifying a mathematical expression in a text document, marking it and making possible processing suggestions. This object is achieved with the characterizing features of the Hauptansprüchs.

Other inventive features are the dependent claims, as well as

See description in detail.

The inventive method for identifying and identifying at least one mathematical expression and / or arithmetic component in a document is characterized by the following steps:

 - receiving the at least one document;

 - searching the data of the document for data of mathematical expressions and / or arithmetic expressions; and

 Identifying the mathematical and / or arithmetic expression based on the data in a list of registered entries of a plurality of mathematical expressions and / or arithmetic expressions

The inventive system for automatic identification and

Marking at least one mathematical and / or arithmetic component in a text document, comprising at least one processor and at least one memory device for storing at least one program module, an input unit for inputting signals and a display, which is connected to the system and responsible for Commands of at least one operational program module and at least one

System bus associated with at least one application program module and the processor is characterized by a

Computing Checker module that extracts from the textual data of at least one mathematical expression and this mathematical expression

Compare expression with data from a stored list and respond to an input signal such that suggestions in a window for correct

Notation and further editing are displayed to the user Selection are available and recorded by means of an input signal in the text document.

It is advantageous that the recognized in the text data mathematical

Print automatically marked and, if necessary, stored in a buffer for further use.

A further advantage is that a connection to pre-stored data is made between the data set of the marked mathematical expression in order to compare it with the data of the data set of the marked mathematical expression.

It is also advantageous that, with the aid of an input signal, a window is opened on the basis of the data record marked on the screen of a computer, which contains data of at least one proposed solution.

Furthermore, it is advantageous that the text document is checked for presumable calculations or arithmetic operation. Thus, if in the text numbers or an abstract algebraic expression are identified in connection with the arithmetic operators, eg 25 ^* 35,21 or 3,25 + 4,75- and this text area is then marked and upon release of a signal, e.g. For example, clicking the highlighted text with the right mouse button will display a drop-down list of selectable suggestions and results on the screen, and make these suggestions available for selecting a suggestion, with the record of the selected suggestion included in the text document data.

This will be clarified below using an example of the typical case of an exemplary embodiment. So z. For example, when finding the input arithmetic operation 14.2 + 3 ^* 8.74 in the continuous text of the document, this arithmetic expression is automatically recognized and then - similar to the

Spell checker - marked so that the user with the right click Mouse button o. Ä., According to the settings in the module for the calculation test, from the drop-down list a suggestion, such as

14.2 + 3 * 8.74 = 40.42 y

 14.2 + 3 * 8.74 = 40.42 y

 14.20 + 3.00 * 8.74 = 40.42

Can choose.

The user can then, e.g. BU Hi, select what

then appears in the text. Of course, in principle, all conceivable mathematical expressions can be included in the corresponding memory module without limiting the generality.

The present invention also relates to a simple solution to enable calculations within a text - comparable to a spell checker - in the presence of a corresponding string, the user receives the results as a drop-down list. In the list alternatives are provided, i.a. also a calculator or calculator, so that the calculation can be varied if necessary. Predestined strings are automatically checked and marked for the user.

The subject matter of this invention may refer to nearly all data in a word processing module. A normal computer is thereby replaced as it were. The program for this purpose is provided as a program module and then automatically checks according to the defined default settings or options. Ie. the user gets useful results and calculations almost without extra effort. The subject of the invention relates Thus, on the entire range of word processors installed on notebooks, laptops, computers, smartphones and other hardware,

The advantages of the present invention can be seen in that a

String in the text document is automatically recognized and flagged, whereby the text document is automatically checked for input and change to the relevant strings.

If the marked digit sequence is clicked (key combination

according to the settings), the user receives meaningful

Suggested solutions for the calculation and may also call the calculator.

Of course, the calculation program module also has the

Possibility to configure the functionality via settings (options). For example, the characters for recognizing a calculation rule and / or calculation modalities - deviating from the default settings - can be defined.

Detected or listed calculations (operations) can be stored in a memory. These transactions that have already been made may also be available across documents.

In the drop-down list, a calculator is available, if necessary for processing the mathematical expression entered in the text. Here can the

Calculation added or edited by inserting numbers. Such a calculation can be transferred to the text document at any time. For further functionality, some examples of the string:

Following this, the user can click on the marked mathematical expression with a suitable signal 7. When the user issues an appropriate signal, in the next step a window 18 opens on the monitor 5 containing a plurality of suggestions for spelling and / or a result of the mathematical expression from which the user can select one with a suitable signal, to include this selected proposal 19 in the text document. After that, the program goes to endpoint 20 so that the generation of the text document is continued. In summary, it may be stated that the present invention provides a method and a system (1) for the automatic detection and evaluation of mathematical expressions in a text document. The system 1 for carrying out the above-mentioned method consists, for example, of a normal PC and the associated data input units, such as a keyboard or a mouse. After finding one

mathematical expression in the text document 21 this is marked with a suitable label. Subsequently, this mark can be clicked on by a signal from the user, followed by a window with a plurality of suggestions for further processing of the mathematical expression. The selection of the appropriate expression is carried out by a signal from the user.
