4 is a block diagram for explaining in more detail a knowledge graph construction module according to an embodiment of the present invention.

Referring to FIG. 4 , in order to generate marketing-specific knowledge graph model data according to an embodiment of the present invention, unstructured data classified from marketing document data collected by the channel-based information collection unit 140 and pre-collected structured data And, a large-capacity knowledge graph and ontology information obtained from the open knowledge graph may be required.

For example, the unstructured data for building a marketing-specialized knowledge graph model may be the original text of a marketing web page collected by the channel-based information collection unit 140, and the structured data may be a general-purpose file format or a structured data that can be collected through openAPI It may contain data. In addition, the open knowledge graph data may be domestic and foreign data published in RDF format, and may be obtained by receiving an RDF file or a query response targeting a SPARQL endpoint.

And, in order to build the marketing-specific knowledge graph model data from the collected or classified information, the knowledge graph construction module 151 processes step-by-step through a two-stage pipeline module as shown in FIG. 4 , thereby effectively marketing specialized knowledge Graph model building processing can be performed.

More specifically, referring to FIG. 4 , the knowledge graph building module 151, as a first pipeline module, includes an unstructured data processing unit 1511 , a structured data processing unit 1512 , an open knowledge graph management unit 1515 , and a relational database. 1517 , and may include a natural language analysis unit 1513 , a knowledge graph information conversion unit 1514 , a large-capacity knowledge graph processing unit 1516 , and an ontology information processing unit 1518 as the second pipeline module.

In addition, the data output from the second pipeline may be transmitted to the marketing specialized knowledge graph construction unit 1519 and used to generate marketing specialized knowledge graph model data or keyword analysis information.

First, the unstructured data processing unit 1511 may identify the unstructured data from the marketing document data collected in the first pipeline stage, and transmit it to the natural language analyzer 1513 . The unstructured data may include, for example, text data identified from marketing document data.

In addition, the natural language analyzer 153 may extract main keywords using natural language processing technology from the unstructured data. The natural language processing technology may be exemplified by techniques such as morpheme analysis and entity name recognition, and the natural language analysis unit 1513 may use classification information of the document classification module 153 for more accurate keyword extraction processing.

Then, the extracted keyword may be transmitted to the knowledge graph information conversion unit 1514 . The knowledge graph information conversion unit 1514 is a marketing knowledge graph information that is mapped and integrated into the knowledge graph information in a preset format by a mapping technology such as rule-based marketing keyword mapping or machine learning algorithm-based mapping. Format conversion can be processed.

In addition, the open knowledge graph management unit 1515 may collect and store pre-built open knowledge graph information using an openAPI or the like.

Then, the large-capacity knowledge graph processing unit 1516 pre-builds the large-capacity knowledge graph information prepared so that the collected open knowledge graph information can be mapped to the marketing knowledge graph information that has been format-converted from the natural language analysis information described above, The knowledge graph information may be transmitted to the marketing specialized knowledge graph model building unit 1519 .

On the other hand, the relational database 1517 may collect and store ontology information for semantic mapping between the knowledge graph information converted by the knowledge graph information conversion unit 1514 and the knowledge graph information processed by the large capacity knowledge graph processing unit 1516, Among the stored ontology information, mutually compatible ontology information may be transmitted to the marketing specialized knowledge graph construction unit 1519 .

For example, the marketing-specialized knowledge graph model building unit 1519 collects open knowledge graph information collected from an RDF file or SPARQL Endpoint as knowledge graph model information for processing a large-capacity knowledge graph, and the converted marketing knowledge graph information By building a mapping table between and the large-capacity knowledge graph information, it is possible to build a marketing-specific knowledge graph model.

To this end, the marketing-specialized knowledge graph model building unit 1519 performs mapping processing based on the unique identifier assigned to each data item, but in the case of the same data whose identifiers do not match, the pre-collected ontology information-based relationship information and attributes After calculating the matching probability through the information, data mapping processing for preferentially mapping the high probability may be performed.

5 is a flowchart illustrating an operation of a knowledge graph construction module according to an embodiment of the present invention, and FIG. 6 is a relationship diagram illustrating a knowledge graph construction and semantic mapping process according to an embodiment of the present invention.

5 and 6 are for explaining in more detail the process of generating the marketing-specific knowledge graph model data, the knowledge graph building module 151, first as shown in FIG. 6, is a knowledge graph from OpenAPI or structured file data. Conversion rule information may be obtained (S201).

For example, the conversion rule information may be obtained from a conversion rule file described in R2RML (RDB to RDF Mapping Language), which is a W3C international standard. In addition, the transformation rule information may be converted into knowledge graph transformation rule data using transformation rules described in RML (RDF Mapping Language) from OpenAPI or formatted file data.

Thereafter, the knowledge graph construction module 151 obtains ontology transformation rule information from the relational database (S203), and transforms the natural language analysis information of the unstructured data according to the knowledge graph transformation rule information (S205).

Thereafter, the knowledge graph construction module 151 maps the transformed knowledge graph information to a pre-built large-capacity knowledge graph according to the ontology transformation rule information to build a marketing-specialized knowledge graph model (S207).

As shown in FIG. 6 , the knowledge graph construction module 151 may include a marketing-specific knowledge graph model construction unit 1519 for generating marketing-specific knowledge graph model data. The marketing specialized knowledge graph model building unit 1519 may include the semantic mapping processing unit to efficiently perform the above-described mapping processing with high accuracy. Here, the semantic mapping processing unit may further include a fuzzy algorithm processing unit and a URI identifier processing unit.

More specifically, the semantic mapping processing unit may process semantic mapping between items of data converted into a knowledge graph format (eg, RDF) and a pre-established large-capacity knowledge graph item.

To this end, the semantic mapping processing unit may include a URI identifier processing unit for processing primary mapping by comparing URI identifiers assigned to all data items.

In addition, the semantic mapping processing unit applies a semantic mapping tool between words implemented based on the Levenshtein fuzzy metric algorithm developed according to the linguistic characteristics of Korean from the primary mapping-processed data to obtain automated meaning. Mapping can be handled. The data for which the automatic mapping is completed may be subjected to sampling processing, and the processed sampling data may be used for subsequent mapping inspection and correction processing.

Meanwhile, the knowledge graph construction module 151 may acquire knowledge graph model data on which semantic mapping is completed as marketing-specific knowledge graph model data. For example, the knowledge graph construction module 151 may integrally generate a knowledge graph model by importing the mapped knowledge graph data into a triplestore type database in which a large amount of previously built knowledge graph data is stored. have.

Accordingly, it is preferable that the final knowledge graph model be described as an RDF (Resource Description Framework) data model, which improves compatibility and analysis efficiency.

In addition, the classification system for each item of the established large-capacity knowledge graph may be a marketing-specialized system created by a domain expert in the marketing field. By collecting and combining the brand and product classification system information of major portal services, it is possible to construct and process a more efficient large-capacity knowledge graph. To this end, the open knowledge graph management unit 1515 manages the classification system for each field based on the public interest (which can be calculated as the number of searches for each period of the main portal service) corresponding to each classification system keyword, and the classification system for each field may decide to keep or archive.

According to this knowledge graph model construction, the apparatus 100 for providing marketing information analysis service according to an embodiment of the present invention, the problem of not reflecting the latest keywords pointed out as a disadvantage of the general knowledge graph, the Korean-based knowledge graph and It solves the difficulty of building dictionary data for analysis, facilitates marketing trend and keyword analysis through the establishment of a marketing-specialized knowledge graph model, and makes accurate marketing at a lower cost by facilitating the reflection of new words and Korean keyword analysis in particular. It has the advantage of being able to provide information analysis services.

7 is a block diagram illustrating a document classification module according to an embodiment of the present invention in more detail, and FIG. 8 is a flowchart illustrating a document classification processing process according to an embodiment of the present invention.

In collecting marketing document data for building a marketing-specialized knowledge graph model according to an embodiment of the present invention, the quality of data to be analyzed is a very important factor. In particular, data collected by online crawling, etc. includes a large amount of various types of garbage data, causing problems such as distortion of data analysis values and waste of system resources.

A method of processing this mechanically based on machine learning has also been proposed, but there is a limit to processing garbage data fragmented into various types. In particular, in the case of the original Korean text, the classification accuracy is falling compared to the English language due to the complexity of the original text pattern and the lack of learning data itself.

Therefore, the document classification module 153 according to an embodiment of the present invention builds a hybrid classification system in which a machine learning algorithm and a rule-based algorithm for building a marketing-specialized knowledge graph model are combined to reach a high level of garbage filtering accuracy. make it possible

To this end, the document classification module 153 includes a classification system definition unit 1531 , a rule-based filtering unit 1532 , a model learning unit 1533 , and a machine learning filtering unit 1534 .

The classification system definition unit 1531 performs linear discriminant analysis (LDA) analysis on the marketing document original data collected and transmitted from the channel-based information collection unit 140, and classification system information according to the result of the execution define Here, the linear discriminant analysis is a method of classifying an arbitrary class by arbitrarily defining a group through mechanical learning.

The classification system definition unit 1531 receives the collected marketing document data original information, topic number information, and a relevance metric value as LDA analysis information, and as an LDA analysis result, the original topic group information and a schedule that appears frequently by group Number of keyword information can be output.

In addition, the classification system definition unit 1531 may adjust the number of topics and the related metrics within a meaningful predetermined number, and may process repetitive LDA analysis.

Then, when the LDA analysis result information is finally determined, the classification system definition unit 1531 generates classification system information from the analysis result information and transmits it to the rule-based filtering unit 1532 .

The classification system information may include, for example, garbage topic selection information having a specific pattern for each step. For example, level 1 is advertisement, non-advertisement, level 2 is public relations, real estate, stock, transaction, etc. level 3 is event, experience group, product repair and installation, rental, rental sale, stock, transaction sales, and other classification system It may include cataloging information of garbage keywords that appear frequently.

Accordingly, the rule-based filtering unit 1532 may perform a rule-based primary filtering process of the marketing document data using the classification system information received from the classification system definition unit 1531 as a rule. Accordingly, data primarily classified as a garbage document based on a rule may be removed from the analysis target classification data. Here, the primary filtered remaining data is transferred to the machine learning filtering unit 1534 .

On the other hand, the model learning unit 1533 performs a document classification model learning process using a pre-established training set, and the machine learning filtering unit 1534 performs 2 classification processing using the model learning information from the primary filtered data. Carry out tea filtering.

Accordingly, data classified as garbage data again by the machine learning filtering unit 1534 may be included in the removal data, and only the remaining data may be classified and processed as normal collection data.

8, first, the rule-based filtering unit 1532 sets a rule module according to classification system definition information defined from the collected documents (S501).

The rule-based filtering unit 1532 may filter sentences in which garbage keywords that frequently appear for each classification system appear. To this end, the rule-based filtering unit 1532 may set a rule module corresponding to the classification system definition information. In addition, the rule-based filtering unit 1532 analyzes the original marketing document data collected by the channel-based information collection unit 140 according to whether it meets the garbage classification system defined in the rule module and the linguistic rule condition. Garbage classification analysis can be performed. Accordingly, the primary filtering classification is processed (S503).

For example, a sentence containing the keyword 'one room' may be determined to be garbage in the 'real estate' category.

Accordingly, data classified as garbage and residual data may be classified, and the residual data may be transmitted to the machine learning filtering unit 1534 .

The machine learning filtering unit 1534 performs secondary filtering processing according to the document classification based on the learning model processed by the model learning unit 1533 . The model learning unit 1533 pre-learns machine learning-based classification information (S505), and the machine learning filtering unit 1534 performs a corpus formation process for learning and a predictive model process for predicting classification labeling using the learning model. can do.

As a result, the secondary filtering classification based on machine learning learning information of the primary analysis residual data is processed (S507), and the processed data may be output as garbage data.

9 is a diagram illustrating a classification system definition according to an embodiment of the present invention.

Referring to FIG. 9 , classification system information according to an embodiment of the present invention may be defined by spam topic clustering according to a preset number of LDA analysis and adjustment, and the final classification system modeled by the rule-based filtering unit 1532 may be layered and processed for each step.

As shown in FIG. 9 , it can be confirmed that the rule-based primary filtering keyword is set in stages through LDA analysis, and the primary processing result of the rule-based filtering unit 1532 and the machine learning filtering unit ( 1534) can be processed as a hybrid, resulting in more accurate (garbage filtering accuracy of 80% or more achieved). This helps in quick data-based decision making, and can reduce the time and manpower used to build the existing heuristic rule-based filtering system.
