Problems solved by technology

[0004] However, none of the above-mentioned methods achieves automatic content acquisition, consumes a lot of manpower, and consumes a lot of time for reading the entire text; it is difficult to achieve horizontal comparison of a large number of documents, and it is impossible to solve the problem of document similarity distinction, and there are cases of repeated reading; When only the abstract and keywords are read, the amount of effective information provided by the article is too small; the use of automated methods such as crawlers does not realize the distinction between article content and article type, and the amount of content obtained is large but of low quality; it is impossible to count the frequency of keywords in the article , it is difficult to judge the value of the article to readers before reading the article

Abstract

Embodiments of the invention provide a literature content retrieval and recognition method and device. The method comprises the steps: storing and reading a target article by utilizing a distributed calculation engine architecture, carrying out splitting of the target article, and obtaining the statement and vocabulary of the target article; removing invalid vocabularies in statements and vocabularies of the target article by utilizing the word stop library; inputting the statements and the vocabularies without the invalid vocabularies into a pre-generated similarity analysis model in sequence, and extracting all the statements similar to the content of the target statement library in the target article and all the vocabularies similar to the content of the target lexicon in the target article; wherein the target word bank, the stop word bank and the target statement bank are obtained by carrying out word bank division in advance according to expected specific contents; wherein the pre-generated similarity analysis model is generated by utilizing a logistic regression algorithm based on contents in the target statement library and the target word library. Automatic acquisition of literature contents can be realized, a large amount of literature reading work can be handled, repeated reading is avoided, and the workload is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method and device for document content retrieval and identification. Background technique [0002] With the increase of technical literature in various industries, reading literature in a certain technical direction and acquiring core knowledge content has become one of the important tasks of professional and technical personnel. [0003] In the process of document reading, the content of the document is the most important part, and it is also the ultimate goal of the reader. At present, in the face of a large amount of literature content, the common practice is to adopt methods including: fine search method, reverse reading method, catalog method and other automatic methods. Among them, the fine search method is to reduce the number of hit targets by adding multiple keywords when searching, and to filter the results of the reading documents; th...
