Embodiment 1

[0229] A system to help users find searchable features from submitted input text

[0230] see figure 1 As shown, the figure shows a system for acquiring features that facilitate retrieval according to an embodiment of the present invention. The system 100 runs on a computer system as follows:

[0231] In the preparatory step, each reference document in the reference document collection 152 is scanned by the first characteristic data generating means. When scanning a reference document, the first feature data generating device saves each recognized word consisting of consecutive English letters into a trie, and the count corresponding to the word in the trie is increased by 1. When scanning is completed, the dictionary tree includes all English words in the reference document collection 152 and the total number of occurrences of each word in the reference document collection 152 . Each English word is the first comparison feature, and the total number of occurrences of each...

Embodiment 2

[0257] A system for evaluating the value of things related to user-submitted input text.

[0258] see again Figure 4 As shown, the figure shows a system for evaluating the value of things related to input text submitted by users according to an embodiment of the present invention. The operation of the system 400 includes the following steps:

[0259] In the preparation step, each document in the reference document collection 152 is scanned in turn by the first characteristic data generating means 406 . For the document currently being processed, scan the document and recognize every English word. Whenever an English word is recognized, check whether the word exists in the first trie. If it does not exist, the word is added to the first dictionary tree, and the word is also added to the second dictionary tree, and the document count of the word in the second dictionary tree is increased by 1. Whenever a document is scanned, the first dictionary tree is emptied. After all ...

Embodiment 3

[0274] A system for evaluating someone's career strengths based on their resume.

[0275] see again Figure 5 As shown, the figure shows a system for evaluating a person's career advantages based on his or her resume according to an embodiment of the present invention. This system 500 is based on the aforementioned system 400, more specifically:

[0276] (1) The input text is resume text 551

[0277] (2) The reference document collection is the resume library 552, which stores the resume texts of several people

[0278] (3) The second reference document set is the recruitment notice library 553

[0279]The first feature data stores the keywords that appear in the resume database, and the number of documents in which each keyword appears in the resume; the second feature data stores the keywords that appear in the job posting database, and each The number of documents in which keywords appear in how many resumes. Stored in the array 454 are keywords appearing in the resume...

Abstract

The invention relates to a system and a method for acquiring characteristics favorable for text retrieval. By using the system and the method, a user can acquire the characteristics which are related to personal retrieval requirements and are favorable for retrieval, such as a key word, a sequence, a grammatical pattern, a semantic role and the like. By means of the characteristics, the user can construct more effective query so as to improve the efficiency of searching documents; on the other hand, the invention also relates to a system and a method for evaluating the value of things related with an input text, wherein the user can acquire the evaluation of various things related with the input text by submitting the input text; simultaneously. The invention also relates to a system and a method for evaluating career advantages according to a resume of a person at the same time, which provide career advantage grade of various skills and experiences related to the resume of the person by means of a job notice library and / or a resume library; and the invention also relates to a system and a method for document retrieval by using a text as a query input, which can quickly shrink a retrieval range and avoid losing a search result with potential value.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to the field of text retrieval technology and text processing, and specifically refers to a system and method for acquiring features that are helpful for text retrieval, and a system and method for evaluating and inputting the value of things related to text to users , A system and method for evaluating a person's career advantages based on his or her resume, and a system and method for document retrieval using text as query input. Background technique [0002] As an aspect of the present invention, how to improve the retrieval effect is an important issue in the network era.
