Referring to FIG. 1B , FIG. 1B is a schematic diagram of a file sharing system 100 according to other embodiments of the present disclosure. As shown in FIG. 1B , compared to FIG. 1A , the file sharing system 100 of FIG. 1B further includes a storage server 130 . The storage server 130 is connected to the user devices 110 ( 1 ) to 110 (N) and the data processing server 120 .

In this embodiment, the storage server 130 receives a plurality of input files from the user devices 110(1)-110(N). In other words, these input files are mainly stored in the storage server 130. In some embodiments, the data processing server 120 may request the storage server 130 to receive these input files.

Refer to FIG. 2 , which is a flow chart of a file sharing method according to some embodiments of the present disclosure, wherein the file sharing system 100 shown in FIG. 1A can be used to execute the file sharing method in FIG. 2 .

As shown in FIG. 2 , the file sharing method includes steps S210 to S230. First, in step S210, a plurality of input files are transmitted to the data processing server 120 by the user devices 110 ( 1 ) to 110 (N), wherein the file names of the plurality of input files comply with the file naming regulations. In other words, any input file with a file name that complies with the file naming regulations can be uploaded to the data processing server 120.

Furthermore, in step S220, the data processing server 120 generates a plurality of file tags associated with the plurality of input files according to the plurality of file names, and generates an index tag tree corresponding to the plurality of file tags according to the plurality of file tags.

In some embodiments, each of the multiple file names includes a project name, a project section, and a document name, wherein the data processing server 120 generates multiple file tags corresponding to the multiple project names, the multiple project sections, and the multiple document names, respectively.

The following will explain the file names and file tags using actual examples.

Referring to FIG. 3 , FIG. 3 is a schematic diagram of a file name FN and a plurality of file tags TG1 to TG3 according to some embodiments of the present disclosure. As shown in FIG. 3 , the file name FN includes a reverse creation date pt1, an item name pt2, an item part pt3, a file name pt4, a version number pt5, a reversion number pt6, and a document file extension pt7. The item name pt2, the item part pt3, and the file name pt4 can be read by the data processing server 120, and the item name pt2, the item part pt3, and the file name pt4 are used as file tags TG1 to TG3, respectively.

In some embodiments, the data processing server 120 may establish a tag quantity ranking based on the tag quantity statistics generated by each of the multiple file tags. Then, the data processing server 120 may read multiple file tags related to the multiple file tags based on the tag quantity ranking, and establish a data tag tree according to the mutual correlation of the multiple file tags, and the multiple nodes in the data tag tree respectively correspond to one of the file tags. Then, the data processing server 120 may generate a tag frequency style table based on the data tag tree, and the tag frequency style table includes multiple tag frequency styles and multiple style counts of the multiple tag frequency styles, and each of the multiple tag frequency styles is an arbitrary combination of each of the multiple file tags. Then, the data processing server 120 may generate an index tag tree according to the plurality of file tags, the tag quantity sorting, and the tag frequency pattern table.

In some embodiments, the data processing server 120 can sort the plurality of file tags according to the number of tags of each file tag, and build each of the plurality of file tags into the plurality of first-level nodes on the index tag tree in order from small to large, and each of the plurality of first-level nodes and each of the plurality of lower-level nodes respectively correspond to one of the file tags. Then, the data processing server 120 can read the plurality of tag frequency patterns according to the plurality of first-level nodes of the index tag tree, and arrange each of the plurality of tag frequency patterns in order from large to small according to the reverse order of the tag number sorting to the plurality of lower-level nodes. Then, the data processing server 120 may establish multiple horizontal links of the index tag tree to multiple lower-level nodes corresponding to the file tags of the multiple first-level nodes according to the multiple first-level nodes of the index tag tree.

The following will use a practical example to illustrate the creation of an index tag tree.

Referring to FIG. 4, FIG. 4 is a schematic diagram of establishing a tag quantity ranking 430 according to some embodiments of the present disclosure. As shown in FIG. 4, the data processing server 120 automatically generates a plurality of file tags TG1-TG7 for the file names of a plurality of input files, and establishes a tag data table 410 according to the corresponding relationship between the input files and the file tags TG1-TG7, wherein the tag data table 410 has 6 input files, numbered from 1 to 6.

In detail, the data processing server 120 automatically generates a file tag for each input file name, wherein the file tag includes 7 tags TG1~TG7 (which respectively represent the tag contents such as "Caiwei International", "OA-Cloud", "Meeting", "ProjectA", "ER Diagram", "Backend Architecture", "ProjectB", etc.) and but not limited to these.

In the tag data table 410, the file tags automatically generated by the input file numbered 1 include tags TG1 to TG3, and the file tags automatically generated by the input file numbered 2 include tags TG4 and tags TG2 to TG3. Similarly, the file tags automatically generated by the input file numbered 6 include tags TG7, TG2, and TG6.

Furthermore, the data processing server 120 generates a label quantity statistics table 420 by counting the number of automatically generated file labels in the label data table 410. The data processing server 120 sorts the file labels in the label quantity statistics table 420 from the label TG1 with a number of 6 to the label TG2 with a number of 1 to generate a label quantity sorting table 430.

Referring to FIG. 5, FIG. 5 is a schematic diagram of establishing a data tag tree TT according to some embodiments of the present disclosure. As shown in FIG. 5, continuing from FIG. 4, the data processing server 120 reads multiple file tags of multiple input files according to the tag quantity sort 430 to establish the data tag tree TT.

Furthermore, the data processing server 120 reads the file tags (including tags TG1~TG3) generated by the input file numbered 1 in the tag data table 410 according to the tag quantity sorting 430 in Figure 4, starting from the tag TG1 with the highest sorting, to form the first type PT1 of the data tag tree.

The first form PT1 of the data tag tree includes nodes whose content is file tags and the statistical number of specific tags represented by each node (herein referred to as the first support sup1). At this time, the data processing server 120 generates nodes with the three file tags as content, namely, tag TG1 (Caiwei International), tag TG2 (OA-Cloud) and tag TG3 (Conference), and their respective first support sup1 is 1.

Next, the data processing server 120 continues to read the file labels (including labels TG1, TG4, and TG3) generated by the input file numbered 2 in the label data table 410 from label TG1 according to the label quantity sorting 430 to form the second type PT2 of the data label tree. In detail, because label TG2 originally exists in the node of the first type PT1 of the data label tree TT, it is only necessary to change the first support sup1 of label TG1 from 1 to 2, and then generate the nodes of label TG4 and label TG3 whose respective first support sup1 are both 1.

Next, the data processing server 120 continues to read the file tags (including tags TG1, TG4, and TG5) generated by the input file numbered 3 in the tag data table 410 from tag TG1 according to the tag quantity sorting 430 to form the third form PT3 of the data tag tree. Specifically, the data processing server 120 only needs to change the first support sup1 of tag TG1 from 2 to 3, and then generate nodes of tags TG4 and TG5 whose first support sup1 is 1.

By analogy, the data processing server 120 reads the file tags (including tags TG5~TG7) generated by the input files numbered 4~6 in the tag data table 410 one by one. After reading the multiple tags generated by the input file numbered 6 in the tag data table 410, the establishment of the data tag tree TT is completed.

Referring to FIG. 6, FIG. 6 is a schematic diagram of a tag frequent style table SFP according to some embodiments of the present disclosure. As shown in FIG. 6, the data processing server 120 generates a tag frequent style table SFP according to the tag content of each node of the data tag tree TT and its first support sup1, wherein the tag frequent style table SFP includes multiple tag frequent style FPs, and the number thereof is the style count Count, and each tag frequent style FP includes one or more tags.

Taking the first frequent tag style FPa in the frequent tag style table SFP as an example, the content of the frequent tag style FPa includes the tag TG1 and the tag TG2, and the style count Count of the frequent tag style FPa is 1, which means that in the data tag tree TT, the number of content tag combinations of the tag TG1 and the tag TG2 is 2. Similarly, the data processing server 120 can calculate all frequent tag styles FP and their style counts Count in the data tag tree TT to complete the frequent tag style table SFP.

Referring to FIG. 7A, FIG. 7A is a schematic diagram of establishing a first-level node FLN of an index tag tree according to some embodiments of the present disclosure. As shown in FIG. 7A, the data processing server 120 builds the first-level node FLN of the index tag tree from left to right starting from the lowest-ranked tag TG2 according to the tag quantity sorting 430. Then, the data processing server 120 builds the tag TG6. And so on, until the highest-ranked tag TG1 is built into the first-level node FLN of the index tag tree. The statistical number of times the tag appears in the first-level node FLN is referred to as the second support sup2. Taking the leftmost first-level node FLN as an example, the second support sup2 of the tag TG2 is 1.

Refer to FIG. 7B, which is a schematic diagram of establishing a lower-level node LLN of an index tag tree according to some embodiments of the present disclosure. As shown in FIG. 7B, the data processing server 120 reads the multiple tag frequency patterns FPa~FPi in FIG. 6 in sequence starting from the highest-ranked tag, and builds them into the lower-level node LLN of the index tag tree from right to left.

Taking the first data in the tag frequent pattern table SFP as an example, the tag frequent pattern FPa content is "Caiwei International" and "OA-Cloud", and its pattern count Count is 1. The data processing server 120 creates a tag TG2 (OA-Cloud) in the lower node LLN according to the tag TG1 (Caiwei International) of the first node FLN and its second support sup2 is 1.

Next, the data processing server 120 uses the second frequent tag pattern FPb with the content of "Caiwei International", "OA-Cloud" and "Conference" (whose pattern count Count is 1) to create a tag TG3 (Conference) under the tag TG2 (OA-Cloud) of the lower node LLN according to the tag TG1 (Caiwei International) of the first-layer node FLN, and its second support sup2 is 1. This is repeated until the data processing server 120 uses the 15th frequent tag pattern FPo with the content of "ProjectB" and "Backend Architecture" (whose pattern count Count is 1) to create a tag TG6 with its second support sup2 being 1 according to the tag TG7 of the first-layer node FLN. In this way, each of the label frequency patterns FPa~FPo is built into the lower node LLN of the index label tree IT.

Referring to FIG. 7C , FIG. 7C is a schematic diagram of establishing horizontal links HL of the index tag tree IT according to some embodiments of the present disclosure. As shown in FIG. 7C , the data processing server 120 establishes multiple horizontal links HL according to the file tags TAG of the first-level nodes FLN of the index tag tree IT.

Taking the tag TG2 of the first-layer node FLN as an example, the data processing server 120 will establish a horizontal link HL to the tag TG2 of the lower-layer node LLN connected to the tag of the first-layer node FLN (the horizontal link is the dotted arrow in FIG. 7C ).

Similarly, each lower-level node LLN will establish a horizontal link HL with the first-level node FLN or the lower-level node LLN. This horizontal link HL can facilitate the search for the association between the first-level node FLN and the lower-level node LLN, thereby increasing the browsing speed and requiring only a small amount of memory. After the horizontal link HL is established, the index tag tree IT is established.

Furthermore, in step S230, the data processing server 120 generates user interface display content according to the index tag tree to share the user interface display content with the user devices 110 (1) ~ 110 (N), wherein the display content includes a tag cloud and a tag display bar, and the tag cloud and the tag display bar are used to display the correlation between multiple file tags of multiple input files.

In some embodiments, when one of the user devices 110(1)~110(N) selects one of the file tags in the tag cloud, the display content of the user interface shows the file tags related to one of the file tags and the input files corresponding to the related file tags.

The following is an actual example to illustrate the tag cloud and tag quantity display bar.

Referring to FIG. 8 , FIG. 8 is a schematic diagram of a user interface 800 according to some embodiments of the present disclosure. As shown in FIG. 8 , the display content of the user interface 800 includes a tag cloud TC. The tag cloud TC includes file tags corresponding to the input file.

Tag Cloud TC includes "OA-Cloud" (tag TG2), "ProjectB" (tag TG7), "Backend Architecture" (tag TG6), "ER Diagram" (tag TG5), "Meeting" (tag TG3), "ProjectA" (tag TG4) and "Caiwei International" (tag TG1). If the user clicks "Caiwei International" (tag TG1). Then, the tag content information TCI will be expanded. The tag content information TCI includes the tag display column TVC and all automatically generated files FLS including "Caiwei International" (tag TG1) for the user to browse. There are 6 files FLS including "Caiwei International" (tag TG1).

The tag display column TVC includes all other tags that are directly connected to "Caiwei International" (tag TG1) in the above index tag tree. From the tag display column TVC, you can know which other tags "Caiwei International" (tag TG1) is related to. Users can click other tags from the tag display column TVC to further narrow down the scope of browsing and find the files they are interested in.

Refer to FIG. 9 , which is a flow chart of a file sharing method according to some embodiments of the present disclosure, wherein the file sharing system 100 shown in FIG. 1B can be used to execute the file sharing method in FIG. 9 .

As shown in FIG. 9 , the file sharing method includes steps S910 to S950 . First, in step S910 , a plurality of input files are transmitted to the storage server 130 by the user devices 110 ( 1 ) to 110 (N), wherein the file names of the plurality of input files comply with the file naming convention.

Furthermore, in step S920, the storage server 130 transmits a notification of adding to the data processing server 120. Furthermore, in step S930, when the storage server 130 receives a request from the data processing server 120, the storage server 130 transmits a plurality of input files to the data processing server 120.

In other words, the input files are all stored in the storage server 130. Whenever the storage server 130 receives a new input file, the storage server 130 will notify the data processing server 120 that a new input file has been uploaded. At this time, the data processing server 120 can request to receive the new input file.

Furthermore, in step S940, the data processing server 120 generates a plurality of file tags associated with the plurality of input files according to the plurality of file names, and generates an index tag tree corresponding to the plurality of file tags according to the plurality of file tags.

Furthermore, in step S950, the data processing server 120 generates user interface display content based on the index tag tree to share the user interface display content with multiple user devices 110 (1) ~ 110 (N), wherein the display content includes a tag cloud and a tag quantity display bar, and the tag cloud and the tag quantity display bar are used to display the correlation between multiple file tags of multiple input files.

The above steps S910-S950 are basically the same as steps S210-S230, and therefore, they are not further described here.

In summary, the file sharing system and method disclosed herein can enable users to easily view files of interest in a virtual office quickly and efficiently based on the tag association of the index tag tree by applying the above-mentioned embodiments.
