detailed description

The above described objects, features and advantages of the present application will become more apparent and understood.

Referring to FIG. 1 , a flow chart of steps of a method for establishing a product chain object database of the present application is shown, which may specifically include the following steps:

Step 101: Obtain a product object from the webpage information;

In the embodiment of the present invention, the product object may be a data object that represents a product, generally an entity word.

Product objects vary in different industries.

For example, for the electronics industry, product objects can refer to mobile phones, tablets, computers, and the like.

For another example, for the food industry, the product object may refer to konjac roast duck, green pepper shredded pork, hot and sour potato silk, and the like.

As another example, for the furniture industry, product objects may refer to sofas, desks, beds, and the like.

In an embodiment of the present application, step 101 may include the following sub-steps:

Sub-step S11, extracting a preset web address;

In the embodiment of the present application, the website information of each industry may be collected in advance and stored in the network database.

These website information may include the website name, the industry of the website, and the website address. Examples of the website can be as follows:

Site name Website industry URL Recipe network food Www.caipu.net Mobile screen network electronic Www.shoujipingmu.net

In the process of creating a product chain object database, you can extract the URL from the site database.

Sub-step S12, crawling webpage information corresponding to the webpage;

In a specific implementation, the webpage information corresponding to the webpage may be captured by a web crawler (also known as a web spider, a web robot, etc.).

The web crawler visits a webpage of the website from the website, reads webpage information (such as title, body, etc.) of the webpage, finds other link addresses in the webpage, and then finds the next webpage through these link addresses, so that the loop continues. Usually until all the pages of this website have been crawled.

Sub-step S13, identifying a website to which the webpage information belongs;

Sub-step S14, extracting a product object according to the first location of the website in the webpage information.

In practical applications, the pages of many websites are generally generated based on the same web page template. Therefore, the structure of these web pages generally has certain rules.

For these websites, product objects can be extracted at a specified first location according to the rules of their structure.

For example, as shown in FIG. 2, in the recipe network, in a partition (div) of a body part of a webpage, generally used to record summary information such as a dish image (not shown in FIG. 2), a dish name, a rating, and the like. .

For this website, you can extract the dish name as the product object in this partition, namely the konjac roast duck.

Step 102: Acquire an association object related to the product object in the webpage information.

An associated object can refer to a data object related to a product in the product chain, generally an entity word.

For example, for mobile phones in the electronics industry, related objects may refer to components such as screens, circuit boards, cameras, etc., and may also refer to manufacturers of production and the like.

For example, in the food industry, the related object may be a vegetable material, a manufacturer that supplies the material, a manufacturer, and the like.

In an embodiment of the present application, step 102 may include the following sub-steps:

Sub-step S21, extracting an association object associated with the product object according to the second location of the website in the webpage information.

In practical applications, the pages of many websites are generally generated based on the same web page template. Therefore, the structure of these web pages generally has certain rules.

For these websites, product objects can be extracted at a specified second location according to the regularity of their structure.

For example, as shown in FIG. 2, in the recipe network, content information such as materials and practices of a dish is generally used in a partition (div) of a body portion of a web page.

For this website, you can extract the material of the dish as the associated object in this partition, that is, duck half, konjac tofu, garlic 3, ginger 1 small, pickled pepper 3, oil 2 tablespoons, boiling water amount.

In another embodiment of the present application, step 102 can include the following sub-steps:

Sub-step S22, extracting a preset production object;

Sub-step S23, when the production object produces the product object, the production object is set as an association object.

Production objects, which can refer to data objects that are produced (including production, sales, etc.) in the product chain, are generally entity words.

For example, for a mobile phone in the electronics industry, a production object can be a manufacturer of a mobile phone, or a merchant selling a mobile phone, and the like.

Further, for example, for a dish type in the food industry, a production target can produce a restaurant of the dish type or the like.

In the embodiment of the present application, the manufacturer information may be collected in advance, and a structured vendor database is built. The manufacturer database may include the marketing content of the production object (including the product that can be produced), and may also include the marketing data of the manufacturer. The granularity of each product can also include user behavior data such as clicks, comments, orders, purchases, and more.

It should be noted that the object of the production may be an online manufacturer or an offline manufacturer, and the embodiment of the present application does not limit this.

If it is detected that a production object in the vendor database can generate the product object, the production object is set as an associated object relative to the product object.

Step 103: Identify an industry to which the product object belongs;

In the specific implementation, since the website industry is recorded in the network database, and the content of the website in many websites is mostly consistent with the industry of the website, for these websites, the industry of the website can be identified as the industry to which the product object belongs.

For example, in the recipe network, the basic introduction of the dishes and the representation of the product objects of the dishes can directly divide the industry into the food industry of the recipe network.

However, some comprehensive websites, such as portal websites and encyclopedia websites, cover many industries. Therefore, for these websites, the text classifier can be used to identify the industry to which the product objects belong.

Preprocessing the product object before entering the product object into the text classifier, for example, removing numbers, hyphens, punctuation, special symbols, converting uppercase letters to lowercase letters, stopping words, filtering words that are worthless to the classification ,and many more.

The text classifier can be implemented based on algorithms such as naive Bayes, KNN (k-Nearest Neighbor algorithm).

Take KNN as an example, if a sample (such as a product object) is the k most in the feature space Most of the samples (ie, the nearest neighbors in the feature space) belong to a certain category, and the sample also belongs to this category.

In KNN, the selected neighbors are all objects that have been correctly classified. The method determines the category to which the samples are to be classified according to the category of the nearest neighbor or samples.

Step 104: Establish an industry relationship between the product object and the associated object according to the industry;

For a collection of entities in the same industry (that is, a collection of product objects and associated objects), you can construct relationships between entities (that is, between product objects and associated objects).

It should be noted that in each industry, the industry relationship between product objects and associated objects is different.

For example, for the mushroom industry in the food industry, the materials include konjac, duck, etc., and the merchant that can make the dish is the A shop. Therefore, the established industry relationship is that the mushroom simmered duck meat [material] konjac, Mushroom simmered duck meat [material] duck, mushroom simmered duck meat [production] A shop and so on.

In the embodiments of the present application, most of the industry relationships may include product composition relationships and/or product production relationships.

The product composition relationship may be a relationship between the product and other objects used for the production of the product. Other objects may be products or raw materials, which is not limited in the embodiment of the present application.

For example, the industry relationship established between mushrooms and duck meat and konjac, ducks and other materials is a product composition relationship.

For example, the industry relationship established between mobile phones and circuit boards, cameras, sensors and other components is a product relationship.

Product production relationships are thought to be the relationship between the product and the manufacturer that produced the product.

For example, the industry relationship established between the mushroom and the A shop is the product production relationship.

Of course, the above-mentioned industry relationship is only an example. When implementing the embodiments of the present application, other industry relationships may be set according to actual conditions, for example, product transportation relationship (the relationship between the product and the manufacturer who transports the product), product storage relationship (product Relationship with the vendor that stores the product) Etc., the embodiment of the present application does not limit this. In addition, in addition to the above-mentioned industry relations, those skilled in the art may also adopt other industry relationships according to actual needs, and the embodiments of the present invention do not limit this.

Step 105: Store the product object and the associated object as an industry object, and store the relationship with the industry in a product chain object database of the industry.

In the embodiment of the present application, each industry has at least one product chain object database, also known as a knowledge graph, which is essentially a semantic network, and its nodes generally represent an entity or a concept. Generally represents various semantic relationships between entities/concepts.

In the embodiment of the present application, the node of the product chain object database represents an industry object, that is, a data object in the industry, and the edge represents an industry relationship, that is, an industry object and an industry object are recorded in a product chain object database of an industry. Industry relations.

Among them, industry objects can be divided into product objects and associated objects. Of course, product objects and associated objects are relatively speaking. An industry object can be a product object relative to certain industry objects, or it can be relative to certain industries. The associated object of the object.

For example, the screen is an associated object with respect to the mobile phone, and is also a product object relative to the display screen, the touch screen, and the like.

If the product object, the associated object, and the industry relationship are identified, the product chain object database of the industry to which the product object belongs can be extracted, and the product object, the associated object, and the industry relationship thereof are stored.

Since the naming of various industry objects in the industry is not completely uniform, there may be differences. Therefore, before storage, product objects and associated objects can be normalized to obtain standard naming.

In a specific implementation, the vendor database may also store the standard names of the industry objects in each industry and the non-standard names that may appear corresponding to each standard name.

According to the correspondence between the standard name and the non-standard name, if the product object and the associated object are named as non-standard names, they can be converted to standardized names.

For example, the duck is normalized into a duck, the konjac is turned into a hoe, and so on.

In an embodiment of the present application, step 105 may include the following sub-steps:

Sub-step S31, searching for the product object in the industry object recorded in the product chain object database of the industry.

In the embodiment of the present application, the product object may be searched in an industry object recorded in the product chain object database to confirm whether the product object has been recorded in the product chain object database.

It should be noted that the product object is an independent attribute of the industry object. When the product object has the same name as the industry object, it does not mean that the industry object is a product object.

For example, the currently acquired product object is a screen, the associated object is a display screen and a touch screen, and the product chain object database of the electronic industry to which the screen belongs is extracted. In the product chain object database, the mobile phone is recorded as a product object, and the screen is relative to the mobile phone. Associating an object, even if the screen has been recorded, the screen is not a product object, so it is confirmed that the screen as a product object is not found.

Sub-step S32, when the product object is not found, the product object is recorded in a product chain object database of the industry.

In one case, an industry object has the same name as the product object, but is recorded as an attribute of the associated object.

In this case, the industry object can be directly set as the product object.

In another case, there is no industry object with the same name as the product object.

In this case, you can add an industry object to the name of the product object and set it as the product object.

Sub-step S33, searching for the associated object in the industry object recorded in the product chain object database of the industry.

If the product object is not found, the associated object can be further looked up in the industry object recorded in the product chain object database.

It should be noted that the associated object is relative to the product object, and is not an independent attribute of itself. Therefore, regardless of whether the attribute of the industrial object is a product object or an associated object, it can become an associated object of the current product object, that is, when the association is associated. When an object has the same name as an industry object, the industry object can be considered a product object.

For example, the currently acquired product object is a screen, and the associated object is a display screen and a touch screen. The product chain object database of the electronic industry of the screen is taken. In the product chain object database, the touch screen is recorded as a product object, and the display screen is an object associated with the television. Therefore, it is confirmed that the display screen and the touch screen as the associated objects are found.

Sub-step S34, when the associated object is found, the product object and the associated object are connected in the industry relationship.

If an associated object is found, the node that is the product object and the node that is the associated object can be connected as an edge in an industry relationship.

Sub-step S35, when the associated object is not found, the associated object is recorded in a product chain object database of the industry.

If the associated object is not found, there is no industry object with the same name as the associated object.

In this case, you can add an industry object with the name of the associated object, and set it as the associated object.

Sub-step S36, connecting the product object and the associated object in the industry relationship.

Sub-step S37, when the product object is found, the product object, the associated object, and the industry relationship are ignored.

If the product object is found, it means that the product object, the associated object and its industry relationship have been recorded before, and the current product object, associated object and its industry relationship are ignored.

The embodiment of the present application can obtain a product object and related related objects, identify an industry to which the product object belongs, establish an industry relationship between the product object and the associated object, store the product object and the associated object as an industry object, and store the relationship with the industry to In the industry product chain object database, the product chain object database of the industry is accumulated and updated to gradually improve the data in the product chain, and the establishment of an automated industry product chain object database is realized, avoiding labor through workers, experts, etc. Accumulation, greatly reducing the cost of time, and the amount of data on the network is very large, through the knowledge of the group to compensate for the insufficiency of knowledge of workers, experts and other individuals, reducing the phenomenon of information gap in the product chain, improve efficiency.

In order to enable a person skilled in the art to better understand the embodiments of the present application, a method for establishing a product chain object database of an industry in the embodiment of the present application is described below by way of specific examples.

If the product object screen and its associated object display screen, touch screen and Ding factory are currently extracted from the mobile phone website, the industry that recognizes the screen is the electronic industry, and the industry relationship established between the screen and the display screen is the component, the screen and The industry relationship established between the touch screens is the component, which is produced for the industry relationship established between the screen and the Ding factory.

Extract the product chain object database of the electronics industry, as shown in Figure 3A. In the product chain object database of the electronics industry, the recorded industry objects are TV, display, mobile phone, factory A, factory B, factory C, screen, camera. , circuit boards, and more.

TVs and mobile phones are the product objects, and displays, A factory, B factory, C factory, screen, camera, circuit board, etc. are related objects.

As shown in FIG. 3B, in the product chain object database of the electronic industry, the screen as the product object is not recorded, but if the screen as the associated object has been recorded, the screen can be set as the product object.

In the electronic product chain object database, the display screen has been recorded, as shown in Figure 3C, the display can be set as the associated object, the parts are connected to the screen and the display screen, in addition, the touch screen and the Ding factory are not recorded. , you can add a touch screen and Ding factory and set as the associated object, with the parts as the side to connect the screen and the touch screen, to make the side connection screen and Ding factory.

Referring to FIG. 4, a flow chart of steps of an embodiment of a method for querying a product chain object database of the present application is shown, which may specifically include the following steps:

Step 401: Receive a query request sent by a client.

In the embodiment of the present application, the user may send a query request to the server through a client, such as a browser or a separate application.

Among them, the query request has a query word.

Step 402: Identify an industry to which the query term belongs.

Since the naming of various industry objects in the industry is not completely uniform, there may be differences. Therefore, before the query, the query words can be normalized to obtain the standard naming.

In a specific implementation, the standard name of the industry object in each industry and other non-standard names corresponding to each standard name may be stored in the preset vendor database.

According to the correspondence between the standard name and the non-standard name, if the query word is a non-standard name, it can be converted into a standardized name.

For example, the duck is normalized into a duck, the konjac is turned into a hoe, and so on.

When querying, you can index the query words to find the industry to which the query word belongs.

For example, if the query term is konjac roast duck, the industry to which it belongs is the food industry; if the query term is a mobile phone, the industry to which it belongs is the electronics industry.

Step 403: Query an industry object that matches the query term in a product chain object database of the industry.

In the embodiment of the present application, each industry has at least one product chain object database, also known as a knowledge graph, which is essentially a semantic network, and its nodes generally represent an entity or a concept. Generally represents various semantic relationships between entities/concepts.

In the embodiment of the present application, the product chain object database stores the industry object and the industry relationship, the node of the product chain object database represents the industry object, that is, the data object in the industry, and the edge represents the industry relationship, that is, the product chain object of an industry. The database records the industry relationships between industry objects and industry objects in the industry.

Further, the industry object includes a product object and an associated object, and the industry relationship is a relationship between the product object and the associated object established according to the industry.

In the embodiments of the present application, most of the industry relationships may include product composition relationships and/or product production relationships.

The product composition relationship may be a relationship between the product and other objects used for the production of the product. Other objects may be products or raw materials, which is not limited in the embodiment of the present application.

For example, the industry relationship established between mushrooms and duck meat and konjac, ducks and other materials is a product composition relationship.

For example, the industry relationship established between mobile phones and circuit boards, cameras, sensors and other components is a product relationship.

Product production relationships are thought to be the relationship between the product and the manufacturer that produced the product.

For example, the industry relationship established between the mushroom and the A shop is the product production relationship.

Of course, the above-mentioned industry relationship is only an example. When implementing the embodiments of the present application, other industry relationships may be set according to actual conditions, for example, product transportation relationship (the relationship between the product and the manufacturer who transports the product), product storage relationship (product The embodiment of the present application does not limit the relationship between the manufacturer and the manufacturer. In addition, in addition to the above-mentioned industry relations, those skilled in the art may also adopt other industry relationships according to actual needs, and the embodiments of the present invention do not limit this.

Step 404: In the product chain object database of the industry, use the industry object as a base point to query other industry objects connected by industry relations step by step to obtain a product chain object.

In a specific implementation, the industry object matching the query word may be traversed along the edge to find other connected industry objects, and the product chain object, that is, all or part of the data object in the product chain of a certain product.

In one embodiment of the present application, step 404 can include the following sub-steps:

Sub-step S41, setting the industry object as a product object;

In general, the user queries the product in many cases, so the query word entered can be considered as a product object.

Sub-step S42, searching for a target industry relationship preset in the industry;

Sub-step S43, determining whether the industry relationship of the product object connection matches the target industry relationship; if yes, executing sub-step S44, if not, executing sub-step S46;

In the embodiment of the present application, the target industry relationship may be set in the industry relationship owned by the industry for different industries to control the direction and depth of the product chain object.

For example, in the product chain object database of the electronics industry, in order to control the extension of the product chain object to the component, the component can be set as the target industry relationship, and if other industry objects are parts of an industry object, the industry relationship In line with the target industry relationship, if the industry object is a component of other industry objects, its industry relationship does not meet the target industry relationship.

Sub-step S44, extracting an association object of the industry relationship connection;

Sub-step S45, the associated object is set as a new product object, return to the execution sub-step S43;

If the associated object is identified, the associated object can be traversed as a new product object, ie as a new product.

Sub-step S46, connecting the queried product object and the associated object with the industry relationship to generate a product chain object.

If the target industry relationship is not met, the traversal is over, and the product objects and associated objects are connected in series by industry relationship to obtain the product chain object.

Step 405: Return the product chain object to the client.

When a product chain object is obtained, the product chain object can be sent to the client for display.

In the specific implementation, in order to improve the information acquisition efficiency, the information in the product chain object may be sorted according to certain rules.

In an embodiment of the present application, the query request has a first geographic location, that is, a geographic location where the client is located.

In the case of catering in the food industry, when the industry relationship is the product production relationship, the production object represented by the industrial object is extracted, that is, the data object of the product (including production, sales, etc.) is produced in the product chain.

Querying a second geographic location of the production object, and sorting the production objects according to the distance value between the first geographic location and the second geographic location, and returning the sorted product chain object to the client.

In general, the smaller the distance value, the higher the sorting. On the contrary, the larger the distance value, the lower the sorting.

Of course, in addition to the sorting according to the distance, the sorting may be performed according to factors such as the score, the production quality, and the like, which is not limited by the embodiment of the present application.

In practical applications, in order to improve the efficiency of information acquisition, the user can set certain query parameters to query information in the product chain object.

In one embodiment of the present application, the total cost of production is included in the query request.

When the industry relationship is a product production relationship, the production object represented by the industrial object is extracted, that is, the data object of the product (including production, sales, etc.) is produced in the product chain.

Query the production sub-cost of the production object.

The target production object whose production sub-cost is less than or equal to the total production cost is selected from the production object, and the product chain object including the target production object is returned to the client.
