Iron ox's sadness

Today, a friend sent me a message asking me ：“ I will operate step by step according to your operation video , Set so many properties , Why do I only show one value on the graph ？”

My friend, who can't be named , I call him Da Zhuang here , Dazhuang has just entered the field of data analysis , He is an interdisciplinary career change . There was no programming base before , Not to mention data structures , So I suggested that he first make some excellent applied knowledge maps from some powerful domestic companies （Knowledge Graph） The data analysis tools developed by the technology began to learn , He chose a recently popular data analysis tool “ Intelligence analysts ”, You read that right “ Intelligence analysts ” Is the name of this analysis tool .

Iron bull solved the case

I'm sorry to be so far away , Get down to business , Back to our great strength , What does he mean ？ In fact, the description of Da Zhuang is not very clear , It does not explain the specific position on the diagram where the value is not displayed , Nor is it an entity （Entity） It still matters （Relationship） Also called links or the following data window . According to the slightly vague clues given by the other party , We began to solve the case . The first thought may be , He set up multiple tags , That is, you want the entities in the figure to show , Such as name + ID number , But it's time to plot , The picture only shows the name . Now I doubt , It's about relationship settings , I asked him if the relationship settings were not saved , Or the value you want to display is not selected during setting ？ As a result, Da Zhuang sent me a bunch of voice messages , The description is still not clear , The words are not accurate , No problem , It is not necessary to recite professional terms to be proficient in a new industry , A gradual process is required . I listened patiently for a long time , His operation is correct , Next, you can directly use Tencent conference to open a remote desktop .

The above is a partial picture taken from the relationship settings of the intelligence analyst analysis tool , Then I realized , His operation is really OK , No problem with the software , Intelligence analysts have set the key elements of the knowledge map , In a simple way that ordinary people can easily understand . Entity 、 The relationship is normal , The corresponding data is also displayed in the data window . No problem ？

What's wrong with that ？

My question ！ Are not ！ Actually, everyone has no problem . Why is this so , I mentioned above that Dazhuang is a newcomer to data analysis , In fact, Dazhuang did not understand some basic concepts of the knowledge map . First of all, I will outline the key elements that make up the knowledge map , Entity 、 Relationship 、 attribute （Attribute）, An entity has attributes , Relationships also have attributes . So a basic knowledge map unit , You need at least one entity, one attribute, and one relationship , Or two entities and one attribute . If it's hard to understand, you can understand it like this ：

Xiaomei and Dazhuang are good friends , Also a classmate , Xiaomei is a woman , Dazhuang is a man . Then both Dazhuang and Xiaomei are entities , and “ A good friend ” Is the relationship between these two entities ,“ classmate ” It is also a relationship between two entities . What are the attributes ？ Xiaomei is a woman ,“ women ” Is the attribute of Xiaomei .

When these concepts are clear , Now let's go back to the original question raised by Da Zhuang ：“ Set so many properties , Why do I only show one value on the graph ？”

It turns out that the most fundamental problem is that we do not understand the most basic concepts in the knowledge map . With these concepts in mind, it is obvious that , What he means is the text displayed on the entity , Why only the transaction account name is displayed , Instead of showing all the properties .

According to the definition of knowledge map , Attributes exist in entities and links , Of course, the software of intelligence analyst defines the relationship according to this rule , When the specific data is graphical , Intelligence analysts or any kind of data graphic software , Be sure to consider readability , Therefore, it is necessary to set in the intelligence analyst software “ Label content ” That is, the position marked by the red box in the figure .

Attributes and tags are not a concept ！

In terms of displayed quantity , Is the concept of labels . If it's a property , There are entity attributes and link attributes , these A Multiple properties of the class are A Entities and A Of linked services , It mainly acts on the following pair A Entities and A In depth analysis of links 、 classification 、 Statistics 、 Filter 、 Contrast, etc . The concept of attributes is relatively broad , Any data item , You can set it as an attribute if you like , But follow the principle of belonging , Based on facts . Attributes can also have attribute values , Big and strong -22 year - height -1 rice 6,（ A strong age 28, Take height as an attribute ,1 rice 6, It can be called the attribute value of big and strong height ）

Avoid intense fear

In this way, the user can set the content displayed in the label under the entity when generating the diagram , Generally, a field is set , Such as name 、 cell-phone number 、 Accounts and so on , Of course, you can also set multiple values . If all the attributes of the entity are shown on the diagram , The diagram will become a stack of attributes , It's a nightmare for people with phobia .

So no one will set it like this , So we usually only set an important value for the tag , For example, a name is enough . Of course, sometimes we need to pay attention to the specific attributes of an entity at any time in the diagram , The general knowledge map requires us to manually open entities one by one to see the details .

But the intelligence analyst tool provides a very intimate function . That is the data window .

We can see all the attributes of each entity or link in the data window in real time , What we need to do , Just select it .

Okay , Through the above content, I hope you have understood the entities in the knowledge map 、 Relationship ( link )、 attribute 、 label , All clear .
