[0065] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0066] Understandably, the current method for extracting key information from medical literature typically involves matching multiple key words that correspond to the literature's requirements to screen the literature and locate and extract information paragraphs. While this method can extract some explicit key information to a certain extent, thus initially meeting the needs of basic retrieval and information extraction, it is still a relatively simple processing mode overall. This leads to one-sided or biased extraction results, making it difficult to accurately extract deeper key information from medical literature.

[0067] To address the aforementioned problems, this invention discloses a method and system for extracting key information from medical literature. The method involves receiving literature request information for medical literature, identifying and extracting multiple key keywords, searching a pre-defined literature database to determine multiple key medical literatures, matching, statistically analyzing, and filtering these keywords within the multiple key medical literatures to extract multiple key information paragraphs, acquiring historical browsing data of the multiple key medical literatures, and extracting paragraph browsing data corresponding to the multiple key information paragraphs from the historical browsing data, extracting multiple valid browsing data from the multiple paragraph browsing data, identifying and statistically analyzing the valid browsing time corresponding to the multiple key information paragraphs, comparing the multiple key information paragraphs according to the multiple valid browsing times, extracting multiple key information paragraphs, and displaying them in a key order. This method enables the retrieval of multiple key medical literatures, the matching, statistical analysis, and filtering of multiple key keywords, the extraction of multiple key information paragraphs, and the identification, statistical analysis, and comparison of the valid browsing time of the relevant paragraph browsing data to extract multiple key information paragraphs, and the display of them in a key order. This achieves more comprehensive information extraction, avoids bias and partiality in the extraction results, and accurately extracts deep-seated key information from medical literatures.

[0071] In this embodiment of the invention, a demand interaction window for medical literature is created. In the demand interaction window, the literature demand information input by the user in the form of text, voice, image or video is received. Then, the literature demand information is identified, and multiple key words are extracted from the literature demand information. Then, according to the multiple key words, literature is searched in a preset literature database to determine multiple key medical literature.

[0072] Specifically, in another preferred embodiment provided by the present invention, the step of receiving literature demand information for medical literature, identifying and extracting multiple key keywords, searching in a preset literature database, and determining multiple key medical literatures specifically includes the following steps:

[0075] The document demand information was identified and several key keywords were extracted.

[0076] Based on the aforementioned key keywords, a search is conducted in a pre-set literature database to identify several key medical articles.

[0077] Furthermore, the method for extracting key information from medical literature also includes the following steps:

[0078] Step S102: According to the multiple key words of the requirements, match, count and filter in multiple key medical documents to extract multiple key information paragraphs.

[0079] In this embodiment of the invention, multiple key medical documents are divided into paragraphs, and then the multiple key medical documents are matched according to multiple key words in demand. Multiple relevant information paragraphs are selected, and the number of occurrences of multiple key words in multiple relevant information paragraphs is counted. The multiple occurrences are compared with a preset standard number, and multiple key words that are greater than the standard number are selected from the multiple occurrences. Then, key information paragraphs corresponding to the multiple key words are extracted from the multiple relevant information paragraphs.

[0080] It is understandable that a relevant information paragraph is a document information paragraph containing at least one key word of demand.

[0096] In this embodiment of the invention, the target medical specialty of the user who obtains the interactive input literature demand information is selected. According to the target medical specialty, multiple paragraph browsing data are filtered for effective browsing related to the specialty. Browsing data of people who do not belong to the target medical specialty are removed from the multiple paragraph browsing data, and only the browsing data of people who belong to the target medical specialty are retained, resulting in multiple effective browsing data. Then, the duration of multiple effective browsing data is identified, and the effective browsing time corresponding to multiple key information paragraphs is counted.

[0103] In this embodiment of the invention, multiple valid browsing durations are compared and arranged in descending order, and the comparison and arrangement results are recorded. Then, based on the comparison and arrangement results, the top ten key information paragraphs are extracted from multiple key information paragraphs and marked as key information paragraphs, thus realizing the extraction of ten key information paragraphs. At the same time, from the comparison and arrangement results, the key arrangement results corresponding to the ten key information paragraphs are filtered, and the arrangement order corresponding to the ten key information paragraphs is determined according to the key arrangement results. Finally, the ten key information paragraphs are displayed in a key arrangement according to the arrangement order corresponding to the ten key information paragraphs.

[0104] Specifically, in another preferred embodiment provided by the present invention, the step of comparing multiple key information paragraphs according to multiple effective browsing durations, extracting multiple key information paragraphs, and displaying them in a key arrangement includes the following steps:
