COMPUTING DEVICE AND FILE SEARCHING METHOD USING THE COMPUTING DEVICE

摘要

In a file searching method using a computing device, the computing device connects to one or more terminal devices. An electronic file is obtained from a database when a file name is inputted from one of the terminal devices, and the file is analyzed to obtain a title and text content of the file. One or more keywords are extracted from each of the text content of the file using a term frequency-inverse document frequency (TF-IDF) rule. One or more interested terms are obtained from the keywords according to an importance factor of each of the keywords. The method obtains search results from the database according to the interested terms, and ranks the files according to a relevance degree between each file in the search results and the interested terms. The computing device sends the files with a ranking order to the terminal device.

主权项

1. A computing device connected to one or more terminal devices, the computing device comprising:
at least one processor; and a storage device storing a computer-readable program comprising instructions that, which when executed by the at least one processor, causes the at least one processor to: obtain a file from a database of the storage device when a user inputs a file name from one of the terminal devices, and analyze the file to obtain a title and text content of the file; extract keywords from the text content using a term frequency-inverse document frequency (TF-IDF) rule; calculate an importance factor of each of the keywords, obtain a history record of the keywords for querying the file in a recent period, and obtain one or more interested terms from the keywords according to the importance factor of each of the keywords; obtain search results from the database by performing a search operation according to the interested terms, and calculate a relevance degree between each file in the search results and the interested terms; and rank the files according to the calculated relevance degrees, and send the files with a ranking order to the terminal device.
