information organization tools are constantly enriched and tend to be functionally unified and
extend from controlled vocabularies such as classification schemes and thesaurus to knowledge
organization systems such as semantic network and ontology to meet the needs of large-scale,
diversified and semantic information processing. In the process of development and evolution, how
to abstractly summarize the process flow of information organization, and whether the roles played
by different levels have changed? What are the essential links between different types of tools?
What are the characteristics of the development of information organization tools? This paper
focuses on those core issues and has a study using the method of literature analysis and system
theory. According to the different functions and the process flow, information organization can
be subdivided into resource layer, metadata record layer, and vocabulary layer. This paper makes
a detailed and in-depth analysis of the characteristics, changes and future development of each
layer. The resource layer is the resource objects processed and can be divided into unstructured,
semi-structured or structured objects. The metadata record layer is formed after resource objects
being described and indexed. Metadata set and knowledge organization system constitute the
vocabulary layer, which is the schema of the data network, specifies the basic mode of information
description, and clarifies the selected description elements and their corresponding value types
and ranges. The analysis results show that the key problem of information organization is to
extract the feature items which reflect the semantic meaning from the text accurately. Knowledge
organization system aims at expanding the functions of information organization tools, expanding
library resources to network resources, deepening the description and representation of resources
from original document units to knowledge units, changing from human-oriented construction
to machine understanding, and gradually approaching user needs with finer descriptions. The
knowledge organization system has four characteristics: conceptualization of descriptive objects,
diversification of semantic relations, formalization of descriptive languages and open relevance
of data. This paper systematically describes the process flow of information organization and
clarifies the characteristics and future development requirements of resource layer, metadata record
layer and vocabulary layer in the current stage of development. The deficiency is that there is no
discussion on non-information resource objects and information resource objects respectively.

Data storytelling: From data perception to data cognition
CHAO Lemen & ZHANG Chen 〇a ∗

There are two main methods for data presentation: data visualization and data storytelling.
The difference between them is that data visualization mainly solves the problem of data
perception, while data storytelling focuses more on how to transform data perception into data
