Description

FIELD OF THE INVENTION

The present invention relates to the field of maritime safety and computing, and more particularly, to a method for integrating geospatial and navigation information that ensures maritime safety. Information support (IO) of Electronic Navigation Information Systems (ENIS) is created by digitizing "paper" maps and materials from aerial and space imagery. The peculiarity of marine navigation systems is that the binding document used to ensure the safety of navigation is Lotsiya. The navigators have accumulated the centuries-old experience of seafarers, and to date they are maintained at the present level (up to date) by performing constant corrections. However, due to the complexity of the process of formalizing the information present in the locus (informal text with tables and figures), this information was not included in the ENIS.

The creation of technology for the automatic construction of a multilingual automatic index of electronic digital loci will automatically integrate the information of electronic digital locations of various manufacturers into the information support (IO) of electronic cartographic systems (EX).

State of the art

There are currently several different proposals for integrating geospatial information. One of the options for integrating geospatial information, presented by combining the contents of the “Notices to Mariners” with the contents of the navigation publication (loci), was proposed in the invention of Chinese specialists CN 101587473 “Method for electronically correcting paper nautical publications promptly and conveniently” (author JIANHONG XU). The invention describes a method of electronic proofing of paper lots (navigational aids).

The invention of CN 101587473 includes the following steps:

- collection of information on card numbers, identification of heading numbers (names) and corresponding corrections (changes) in the content of paper locations (navigation publications) that will be corrected (corrected) by a specific work task (task) within a certain period of time as an electronic database "one- one ", which is an analogue of the database" Notices to Mariners ", which contains elements of the correction of navigation charts and manuals for a certain period);

- formation of card numbers, identification of heading numbers (names) and e-mail addresses to which proofs of paper locations (navigation publications) should be sent and which should be received by each ship as an electronic database "two-two";

- according to the search conditions by card number and identification numbers of the headings (names) of paper locations (navigation publications) in the electronic database "two-two" there are card numbers, identification numbers of headings (names) and the corresponding changed contents (fragments of corrections) of paper locations ( navigation publications). Then, through the computer, the card number, the identification number of the title (name) and the corresponding content of the correction (change) of paper locations (navigation publications) are sent, which are transmitted to the specified email address and corrected (corrected) in the electronic database "two-two" to every ship. The “two-two” database is a sample of altered information intended for a specific ship, depending on the area of its navigation and the navigation aids received by it).

Similar systems for integrating the content of certain sections of the Notices to Mariners with already published navigation aids are used in many countries: the USA, Great Britain, Japan, and the Russian Federation (only for electronic navigation charts)

One of the options for integrating geospatial information, including data elements from textual navigation aids (locations, sailing directions), was proposed by Shaw American experts; Kevin B., Chung; Miyi J., Cobb; Maria A. and is described in US Pat. No. 6,950,828, filed September 27, 2005, “Method and Methods for Creating and Maintaining an Object Oriented Geospatial Database”.

The invention described in US Pat. No. 6,950,828 provides for the development of an object-oriented system for creating and maintaining a spatial data structure for use in topological applications. The data is organized in a database that includes spatial location features, attributes, and metadata information in a relational structure through a hierarchy (object relationships). The system provides instances of objects and levels that make up the database in order to enter spatial data into the index of objects through hierarchical levels. Data can be updated while maintaining a spatial connection among objects and levels, and data can be exported to a relational database in a vector format of the product.

The invention described in United States Patent US 6950828 is intended primarily for software and hardware-software products using the VPF format (Vector Product Format, Vector Product Format), as well as two other Raster Product Format (RPF, Raster Product Format) and Text Product Standard (TPS, Text Product Standard), developed and supported by NIMA (National Imagery and Mapping Agency, National Agency for Images and Cartography), as the three main formats for databases (databases) of geographic information (data).

The invention of US 6950828 indicates the need to use within a single platform geospatial data structured in all three formats, one of which is the Text Product Standard (TPS), which is a text format based on the SGML format (Standard Group Mark-up Language). In the invention, US 6,950,828 TPS provides digital textual information from hardcopy versions of NIMA publications, such as the US Practical Navigator and sailing directions. Its information is mainly in SGML format. For example, navigators can use TPS data to supplement paper or digital maps with valuable information, including accurate values.

Despite existing applications (software products) designed to view geospatial data in any of the VPF, RPF, and TPS data formats, there is no single software product for viewing, analyzing, or adjusting (manipulating) information in all three formats on one platform. Therefore, users must access individual programs in order to use data in each format. Establishing Cross-references (cross-references) to data produced in various formats is a difficult task. In the best case, this way the speed of data assimilation is limited and the ability to detect inconsistencies in data from multiple sources, as well as visualize data from multiple sources, is limited.

As you can see, this method is aimed at creating an object-oriented paradigm of geospatial data, while additional software is used to read the TPS format in dialogue mode (using the operator) to use information from navigation aids (sailing directions), navigators can use TPS data to supplement paper or digital maps with valuable information, including accurate values ("... navigators can use TPS data to augment paper or digital charts with valuable information, including accurate directions").

In the work of specialists described in patent US 6950828, the need for integration of information available as part of electronic navigation charts and information from the locus is recorded, for visualization of each of which its own separate software is used.

A specific approach to solving the problem of integrating navigation information is described by Plumlee, M., Schwehr, K., Alexander, L., Sullivan, V., Ware C., in the work "GeoCoastPilot: the best way to organize and visualize information for information support in the port" (GeoCoastPilot: A better way of organizing and displaying information in support of port familiarization "MTS / IEEE, Biloxi, MI, Oct 26-29, 2009., Center for Coastal and Ocean Mapping, UNH 24 Colovos Road Durham, NH 03824 USA) available at: http://vislab-ccom.unh.edu/~schwehr/papers/2009-plumlee-geocoastpilot.pdf

The “Text-tagging Tool.” Section of the above source describes the automated process for adding Coast Pilot text tags (snippets of text), starting with the Coast Pilot chapters (locations created by NOAA) in. rtf format (Rich Text Format) and ending with the presentation of this information in XML format. This process uses fragments from conventional Coast Pilot formatting approaches.

The GeoCoastPilot software and hardware complex provides automatic recognition and marking of headings and subheadings, identifying them as related to formatting items and finding links to the rules (paragraphs of the text of the text) CFR (Code of Federal Regulations. Code of Federal Regulations). CFR number 33 is defined under the heading "Navigation and Navigable Waters".

After recognition of CFR instructions, most of the terms (terms, definitions) stored and marked with "bold" are of particular interest. These terms are automatically identified and inserted into a separate table of candidates for entities (objects). After the table is compiled, each term is (repeatedly) searched for in the remainder of the document and each case is marked as a valid reference to an entity (characteristic) called a term. Further, the text immediately after the term found is analyzed for the presence of geographical coordinates there.

If coordinates are present, then they are included in the table of candidates for entities (objects). This table can be expanded (adjusted) manually so that additional entities are automatically marked even though they do not appear in bold font somewhere in the document. Table entries can also be deleted so that the text marked as "bold", for another reason, was not mistakenly marked as an entity (object). For the few cases where the name is used to mean two different characteristics (for example, "Fort Point"), the tags are made unique by adding a location to the feature ("Fort_Point: New_Castle"). These tags require manual intervention.

The tables generated during this process are subsequently used as a basis (basis) for creating "equivalences" (transcoding elements) of the entities of cartographic systems (handbooks) between Coast Pilot text (s) and ENC data (electronic navigation systems).

Thus, as can be seen from the above translation of the fragment of the article: "GeoCoastPilot: A better way of organizing and displaying information in support of port familiarization", the method for integrating navigation information, proposed and used in the GeoCoastPilot software and hardware complex, provides the automated formation of a monolingual index alphabetical index of entities (geographical names and names of objects of equipment for the navigation situation of the navigation area) with the further use of the manual adjustment mode by specially prepared and specialists, which requires significant human resources and time to process the entire existing collection of locations.

In the document developed by one of the leading Russian manufacturers of marine electronic charts LLC Chart Pilot LLC and the Main Directorate for Navigation and Oceanography of the Ministry of Defense of the Russian Federation in 2005 and regulating "Basic technical requirements for electronic navigation charts (digital marine navigation charts) (for certification), in chapter 7 "Requirements for assessing the content and completeness of map data" it is indicated: "... The assessment of the completeness of the object structure is checked interactively by downloading raster information and a vector map and objective control. "From the above position it is clear that to assess the completeness of the object composition, two of the same type of information source are used: a raster image of the original" paper "map and a newly created version of the electronic map, in vector format, without taking into account information from sources of a different type (book books ). There is no automation of this process. The same document states that “data taken not from the source map should not distort the navigational significance of data taken from the source map (this data must contain the attributes SORDAT and SO RIND).

SUMMARY OF THE INVENTION

Thus, in order to ensure the safety requirements for navigation, in addition to the existing process for describing navigation objects as part of vector electronic navigation charts, there is a need to automate the process of selecting objects contained in navigation aids (locations, sailing directions) in automatic mode (without using an operator), automate the process of establishing Cross-references (cross-references) to fragments of locations and to provide access to data objects contained in locations from objects rientirovannoy system geoprostanstvennyh data used in electronic navigation information systems (Enisa).

To solve these problems, a method is proposed for creating a multilingual automatic index of electronic digital location, which provides the following functions:

1. Automatic creation of an index of geographical names and names of objects of navigation equipment of the navigation area.

2. Automatic creation of an index of geographical names and names of objects of navigation equipment of the navigation area, weakly dependent on the language of the publication of the line.

3. Create multilingual alphabetical indexes.

4. Automatic integration of information included in the information support (IO) of electronic cartographic systems (EX) and electronic digital locations.

5. Automatic integration of the information included in the information support (IO) of electronic digital locations with electronic cartographic systems (EX).

6. Automatic integration of information presented in the traditional official location and information provided in the form of additional media files.

A feature of the method of the present invention is that the integration of information support (IO) of electronic cartographic systems (EX) and electronic digital locations is carried out by: automatically creating an index of geographical names and names of objects of navigation equipment of the navigation area contained in text descriptions of navigation aids (lots); initiating the search for information without formalizing a request to a full-text repository of navigation aids (locations); automatic linguistic processing of the search image and highlighting the elements of the name of the desired object; selection of links corresponding to the desired object; visualization of fragments of navigational aids (locations) corresponding to the desired object.

DETAILED DESCRIPTION OF THE INVENTION

The central element of the electronic digital location is a multilingual automatic index of the electronic digital location, which ensures the implementation of the interconnected functioning of the above functions and the automatic integration of the information included in the information support (IO) of electronic cartographic systems (EX) and electronic digital locations.

The function of automatically creating an index of geographical names and names of objects of navigation equipment of the navigation area is implemented by linguistic processing of the electronic version of the line used to print its official publication (example in Fig. 1) and highlighting all the options for using the terms of geographical names and object names contained in the text navigation equipment navigation area (example in figure 2), through the use of linguistic features of words, character izuemyh like proper names, and the words "frames", for which we can use the list of nomenclature terms defined in national and international sailing instruction on drawing up, and which are required when specifying the geographical names and names of objects of navigational equipment. All options for the use of terms are highlighted:

- excluding the styling of the analyzed text of the text;

- taking into account the inflection of word forms used in distinguished terms, and the language of writing the terms, for example:

a) the national language of the country where the locality was created (for example, Russian);

b) the national language of the country of the described coast and territorial waters (for example, Swedish);

c) the generally accepted international language used to describe marine terminology (for example, English).

In accordance with the Rules of the hydrographic service No. 36. Compilation and publication of manuals and manuals for navigation (ASG No. 36) "when describing individual objects, the nomenclature term and its own name should be given." (p. 20, 40) Example:

Cape Lewin (Leeuwin) (34 ° 22'S, 115 ° 08'E.) See Lotsiyu on the southern coast of Australia.

This requirement of ASG No. 36 makes it possible to distinguish the names of geographical objects and navigation aids (SSS) without taking into account the styling of the analyzed text of the location. Given the small number of words and phrases (about 100 terms), which are used in practice as nomenclature terms (... shore, bay, lighthouse, cape, island, luminous sign, target of lights ...), a list of nomenclature terms is compiled, presented as a separate file, which in the future can be adjusted when new nomenclature terms are identified. In the process of processing the text of the text, words (fragments of the text) are present that are present in the list of nomenclature terms, and if there are words or phrases in the text next to the highlighted nomenclature term with the presence of a proper name attribute, the entire phrase with the page number is stored in the alphabetical index list. A sign of a proper name is a spelling of a word with a capital letter. In this case, various variants of the syntactic structures for writing the names of geographical objects and means of navigation equipment are taken into account, for example:

<nomenclature term> <proper name> - Laptev Sea;

<proper name> <nomenclature term> - the Mediterranean Sea;

<proper name>, <proper name> and <proper name and nomenclature term> - Bear, Birch and Hare islands; etc.

Moreover, from the last example, three names of individual geographical features will be entered in the alphabetical index.

Accounting for word changes in word forms and determining the pseudo-foundations of words used in the analyzed nomenclature terms is ensured by comparing each analyzed word for coincidence with a dictionary containing all variants of word forms of words and phrases used as "frames". At the moment, the dictionary of "rappers", taking into account the different variants of word forms, consists of 648 terms.

The function of automatically creating an index of geographical names and names of objects of navigation equipment of the navigation area, weakly dependent on the language of publication of the line, is also realized through the use of linguistic features of words characterized as proper names and words "benchmarks", for which you can use the list of nomenclature terms defined in national and international guidelines for drafting a program, similar to the way described above. The peculiarity of the use of "benchmarks" in this case is that in addition to the nomenclature terms of the country of publication of the locality, words of the nomenclature terms of the country of the described section of the locality can be added. For example, figure 3 shows a fragment of an American locality describing a section of the coast of Italy, where the terms of the national language (in this Italian example) can be used as the words "reference points": golfo (bay), fiume (river), etc., recorded in English characters using transliteration. Figure 4 also shows a fragment of an American locality describing a section of the eastern coast of Russia, where the terms: Mys (cape), Bukhta (bay), Ostrov (island), etc. can be used as the words “benchmarks”.

The function of creating a bilingual alphabetical index (Fig. 5) during the automated processing of national variants of the location allows you to establish transitive links between fragments of texts of locations of different manufacturers (countries and companies) that describe the same marine geographical areas of navigation, and ensures the creation of a multilingual version of the electronic location .

For example, in Fig. 1, containing a fragment of the location of the Main Directorate of Navigation and Oceanography of the Russian Federation (GUNiO RF), describing the coast of Norway using the "benchmark" methods described above, the following geographical objects can be found: Cape Skaften, Cape Kvalnes, Selena Söura and Korsnes, Skala Galten et al. Analyzing subsequent sequences of characters enclosed in brackets, and using the attribute of words characterized as proper names (capitalized word), and writing the contents in brackets in codes different from the codes of Ana edition of sailing (in this example, English characters), these characters are stored as a sequence of generally accepted international names of geographic features, with the establishment of links between these pairs of terms: Cape Skafti synonym - Skaften; Cape Kvalnes synonym - Kvalnes; The villages of Syoura synonym - Saura; The villages of Korsnes are synonymous with Korsnes; Galten Rocks is a synonym - Galten - and by providing search and visualization of fragments of the location with both national (Russian) and international (English) names of geographical objects.

The function of automatic integration of information included in the information support (IO) of electronic cartographic systems (EX) and electronic digital locations is implemented by:

- the use of monotonous spelling in a natural language of geographical names and names of objects of navigation equipment in accordance with the governing documents of the country of publication of the locality;

- establishing a connection (organizing the search for information without formally filling out a request) between fragments of information support (IO) from the electronic digital location and the object of the electronic cartographic system (Fig.6), selected at the workstation (AWS), with the issuance of a text fragment (- o) Locations in a separate window on the AWS EX (Fig. 7). Access to information is carried out by selecting the item (s) from the "menu list", made up of the names of objects highlighted by a rectangular frame on the selected EX section.

The function of automatic integration of information included in the information support (IO) of electronic digital locations with electronic cartographic systems (EX) is implemented by:

- the establishment and use of linguistic relations between fragments of a textual description of the location, which contain information about the geographical names and names of objects of navigation equipment of the navigation area and the coordinates of the selected objects;

- establishing a connection (organizing the search for information without formally filling out a request) between fragments of information support (IO) from the electronic digital location and the IO of the electronic cartographic system (EX);

- selection of the “menu” element from the list of geographical names and names of objects of navigation equipment used to describe the navigation situation in the navigation area in the indexed paragraph (paragraph) and included in the general DB Index of electronic digital navigation;

- search for the selected “menu” element in the electronic cartographic system (EX) information system and establishing a blinking “cursor arrow” at the point with the coordinates of the object found in the electronic information system (EX) at the base of the conventional symbol displayed on the automated workplace EX;

- Establishment of a blinking "arrow cursor" on the AWS EX at the point with the coordinates of the object present in the IO electronic digital location and not found in the IO EX, with the application of the symbol and name of the object in a separate additional information layer, without changing the main information layers . Saving information in an additional information layer can be performed after confirmation by the operator.

The function of automatic integration of information presented in the traditional official location and information presented in the form of additional media files (audio, video files and files with three-dimensional graphics) displaying the underwater part (bottom topography, underwater part of the berthing structures) and the surface part of the topography of the coastline with the display of coastal structures and objects of navigation equipment, it is realized due to:

- automatic indexing of files with textual descriptions of fields and database records attached to audio, video files and files with three-dimensional graphics, from which geographical names and names of objects of navigation equipment in natural language are distinguished;

- creation of an index of geographical names and names of objects of navigation equipment (subject index of terms) found in media files;

- a selection of terms of geographical names and names of objects of navigation equipment used to describe the navigation situation in the navigation area in the indexed paragraph (paragraph) and included in the general index of the database of electronic digital navigation;

- a subsequent search for index elements in the index of media files, in the description of which the selected terms of geographical names and names of objects of navigation equipment are used;

- launching the media visualization environment in a separate pop-up window and visualizing the found files using the software tool that was used to create them.

The establishment of links and the integration of information is carried out without organizing the formal filling of the request, by selecting the appropriate "icons" that are installed (highlighted by the corresponding background) and become available when viewing the selected paragraph (paragraph) of the location only if the elements of the index index of the analyzed (viewed) paragraphs selected from the general index of electronic digital location are present in the index index of media file descriptions.

The multilingual automatic index of electronic digital location, which was created as a result of the interconnected functioning of the above functions, provides:

- a comparative analysis of the completeness of the contents of navigational aids presented in the form of navigational charts, various independent manufacturers and a text description of the locations prepared for the next reprint by national hydrographic organizations;

- automatic integration of information included in the information support (IO) of electronic cartographic systems (EX) and electronic digital locations.

- clustering of geographical names and names of objects of equipment of the navigation area, present in the classifier of EX objects and the alphabetical index of the line, in the following categories:

- terminological concepts that are present both in the classifier of EX objects, and in the alphabetical index of the locus;

- terminological concepts that are present only in the classifier of ECS objects and are absent in the alphabetical index of the locus;

- terminological concepts present in the alphabetical index of the locus and absent in the classifier of EX objects;

The creation of a multilingual automatic index of electronic digital location allows you to get a technical result in the form of:

improving the safety of navigation due to the automated identification of terminological concepts that are not in the description of the analyzed navigational aids, which can be used as “candidates” for replenishing the content of the navigational aids in an automated mode;

- improving the safety of navigation due to the automated identification of terminological concepts erroneously defined in the description of the analyzed navigational aids;

- integration of hardware and software systems of electronic navigation information systems (ENIS) and electronic versions of navigation aids (locations) without establishing cross-references by the operator in the dialog "manual" mode.
