Embodiment 1

[0022] see figure 1 , this embodiment provides a method for visualizing the similarity of text sets, and the method flow is as follows:

[0023] 101: Preprocessing the text collection;

[0024] 102: Calculate the similarity of the text collection;

[0025] 103: Visualize the similarity of text collections.

[0026] The method provided in this embodiment measures the similarity of text collections by establishing a text collection similarity calculation model, and displays the similarity results in a graphical manner, so that users can intuitively and quickly understand the content and similarity of text collections beneficial effects of information.

Embodiment 2

[0028] see figure 2 , this implementation provides a visualization device for the similarity of text sets, the device includes:

[0029] A preprocessing module 201, configured to preprocess the text set to be subjected to similarity calculation;

[0030] A similarity calculation module 202, configured to calculate the similarity of the preprocessed text set;

[0031] The visualization module 203 is configured to visualize the similarity of text collections.

[0032] Specifically, in the above-mentioned preprocessing module 201, the text collection is divided into words, and the text feature words are obtained after removing the stop words, and the weight of the words is calculated; wherein, the stop words refer to such as "of", "and" and "in " and other prepositions, modal particles and very commonly used words.

[0033] In the similarity calculation module 202, the similarity of the text set is calculated through the feature words of the text set and their weights.

Embodiment 3

[0041] see image 3 , this implementation provides a visualization device for the similarity of text sets, the device includes:

[0042] The preprocessing module 301 is used to preprocess the raw data to be visualized to obtain the feature words and weights of the text collection;

[0043] A similarity calculation module 302, configured to perform similarity calculation on the preprocessed text set;

[0044] The visualization module 303 is configured to use the above results to visualize the similarity of text collections.

[0045] Further, the preprocessing module 301 includes:

[0046] The word segmentation unit 301a is used to segment the text collection and remove stop words to obtain independent feature phrases;

[0047] The word weight calculation unit 301b is used to calculate the weight of the feature words of the text set.

[0048] Wherein, in the word segmentation unit 301a, stop words refer to some prepositions, modal particles or very commonly used words such a...

Abstract

The invention discloses a method and a device for visualizing text set similarity, which belong to the field of text information processing and information visualizing. The method comprises the following steps of: preprocessing text sets; calculating the text set similarity; and visualizing the text set similarity. The device comprises a preprocessing block, a text similarity computing module and a visualizing module. According to the method, a text set similarity computing model is built to measure the text set similarity, a similarity result is displayed in a graphical mode, so that a beneficial effect that users can directly and quickly understand the text set content and similarity information is realized.

Description

technical field [0001] The invention relates to the fields of text information processing and information visualization, in particular to a method and device for visualizing text set similarity. Background technique [0002] With the rapid development of information technology, massive amounts of information are constantly emerging, making it increasingly difficult for people to process and understand them. Although traditional text processing technology has been able to mine important information from big data to a certain extent, the mined information usually still cannot satisfy people's reasonable analysis, understanding and application by means of browsing and screening. Faced with this challenge, text visualization technology emerged as the times require. It expresses the content and laws that are complex or difficult to express in text in the form of visual symbols, and at the same time provides people with the function of quickly interacting with visual information. ...
