# Why can't we organize data well?

## Problems In Organizing Information

> **Problems:** \
> &#x20;  **- Usual information has various attributes, so it cannot be classified on one criteria.**\
> &#x20;  **- Associated information should be kept/listed together.** \
> &#x20;  **- Stored Information should be readily accessible without distraction.**\
> &#x20;  **- Data should be dynamically structured as desired.**

### **Information management process**

1. Collect
2. Analyze
3. **Classify <- Problem is here!**
4. Archive
5. Browse

### Essential elements **of information management system**

* **Structuring <- Problem is here!**
* Integrity
* Safety
* **Accessibility <- Problem is here!**

## Existing Methods In Information Management

### **Keyword Searching**

&#x20;**Pros:**

* Can be used without having to analyze or classify data

&#x20;**Cons:**

* Can not find data if there is no matching keyword in the content of the material&#x20;
  * E.g., multilingual data, source code, image, sound...
* Unwanted result are retrieved together
* Difficult to find if the keywords are not selected properly

### **Directory Tree**

&#x20;**Pros:**

* Ideal for classifying data with single attribute&#x20;
  * E.g., maps, calendars, organizational chart, etc.

&#x20;**Cons:**

* Can't handle `Bat Data`&#x20;
  * Let's try to decide where to put 'a bat' ->  `/HaveWings`?, or `/Mammal`?
* Usual data can not be categorized effectively because its various properties
  * E.g., dates, media types, purposes, subjects, versions, etc.
* Impossible to organize data dynamically with desired criteria
* Difficult to immediate access to desired data

### **Tagging**

&#x20;**Pros:**

* Immediate access to data from selecting one of the listed tags
* Well managed data can be classified into various criteria

&#x20;**Cons:**

* User have to set several tags into each data manually
* Omitting or mislabeling tags can lead to critical defect
* If the meaning between tags are not mutually exclusive, semantic duplication occurs
* Namespace conflicts when tags have the same title

## Introducing \`SlipStack\`

### Data management solution using \`Multiple-Classification Tree\` method

* Excluding the shortcomings of the `directory` method and the `tag` method&#x20;
* Only the merits of two methods are combined
* Streamlined UX reduces users' time and effort

### \`Multiple-Classification Tree\` method:

* Build up several trees for each attributes in semantically exclusively
  * E.g., Who, What, When, Where, Why, How ... etc.
* Assign nodes to the data, corresponding to the attributes of the data
* Selecting nodes in the trees lists up the result of logical operations of items
  * Filtered by selected nodes (`AND`, `OR`, `NOT`)
