In addition, when it is determined that a detailed description of a related known function or configuration may obscure the gist of the present disclosure in describing an embodiment of the present invention, the detailed description will be omitted. In addition, the terms used in the following are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or operator. Therefore, the definitions of the terms used should be interpreted based on the content throughout this specification and the corresponding function.

1 is a block diagram of a user terminal according to an embodiment of the present invention.

The user terminal 100 may be one of a smart phone, tablet PC, laptop, smart TV, smart glasses, smart watch, cellular phone, tablet PC, MP3 player, and PMP, but is not limited thereto.

Referring to FIG. 1 , the user terminal 100 may include a storage unit 110 and a processor 120 .

The storage unit 110 may store various data. For example, the storage unit 110 may store various user data such as text data, image data, video data, and audio data.

Here, the storage unit 110 stores user data as a mass storage device. The storage unit 110 may be a storage medium such as a conventional general mass storage device such as a hard disk or an optical disk or a memory card. Also, the storage unit 110 may be a dynamic random access memory (DRAM) or a mass storage device in the form of a solid state disk (SSD) using a semiconductor device such as a flash memory. Also, the storage unit 110 may be implemented as an optical disk.

The processor 120 may output content included in the web document. Specifically, the processor 120 may output content included in the web document based on the structure of the web document.

In general, web documents are structured in a Document Object Model (DOM). The DOM is an official W3C standard for representing structured documents in a platform/language neutral manner. The DOM is also the basis for several APIs standardized by the W3C.

This DOM is widely used in web documents (or web browsers) through standardization. However, since the DOM does not reflect the way people read sentences as it is, it is unreasonable to apply it as it is to the way that web documents are output according to the selection of people with low vision.

Accordingly, the present invention newly proposes a Sentence Structure Tree (SST) that can be used to selectively output web documents according to the selection of a person with low vision.

3 shows a sentence structure tree according to an embodiment of the present invention.

Referring to FIG. 3 , the sentence structure tree can divide a web document into paragraphs, sentences, objects (objects), and the like.

For example, a web document may be composed of paragraphs. Here, the paragraphs included in the web document may be classified into upper layers. Also, a paragraph may include at least one of a sentence and an object. In this case, at least one of sentences and objects included in a paragraph may be classified as a lower layer. In the above example, the sentences and objects may be defined as hierarchies of the same level, or the characters and objects may be defined as hierarchies of different levels.

As another example, a web document may include at least one of paragraphs and groups. Here, a group may be defined as an object including a table or image. For example, a paragraph or group included in a web document may be classified as a higher hierarchy. Also, a paragraph may include at least one of a sentence and an object, and a group may include at least one object. In this case, at least one of sentences and objects included in a paragraph or group may be classified as a lower layer. In the above example, the sentences and objects may be defined as hierarchies of the same level, or the characters and objects may be defined as hierarchies of different levels.

As another example, a web document may be composed of a group of objects such as titles, tables, and pictures. As another example, a web document may be configured to include paragraphs and objects such as titles, tables, and pictures together, but will not be limited thereto.

In the above example, paragraphs can be separated by <p> tags obtained from the DOM or line breaks, sentences can be separated by periods (.), and objects can be separated by images or tables.

In various embodiments of the present invention described above, the processor 120 may set an output unit that is a unit for outputting information of a web document. Alternatively, the output unit may be preset.

Here, the output unit may be a unit for outputting a part of a web document on a screen or outputting a voice.

For example, when at least one of a paragraph, sentence, and object is selected from a web document, the processor 120 may set at least one of the paragraph, sentence, and object to an output unit to perform output.

For example, when at least one of a paragraph, a sentence, and an object is selected from a web document, the processor 120 may output the selected at least one according to the selected order.

In the above example, it has been described that each of a paragraph, a sentence, and an object is set as an output unit, but is not limited thereto.

For example, when only some of paragraphs, sentences, and objects are selected, the corresponding parts may be set as output units.

For example, when parts of the first paragraph and the second paragraph included in the web document are selected, the first paragraph and parts of the second paragraph may be individually set as output units and sequentially output.

As another example, when the first sentence included in the first paragraph included in the web document and part of the second sentence are selected, the first sentence and part of the second sentence are individually set as output units and output sequentially. can

As another example, when the first sentence included in the first paragraph included in the web document and the image part included in the object are selected, the first sentence and the image part included in the object are individually set as output units, and sequentially can be output as In this case, the image part may be output through a separate description tag tagged with the image part.

As another example, when the first sentence included in the first paragraph included in the web document and the text part included in the object are selected, the first sentence and the text part included in the object are individually set as output units, and sequentially can be output as
