Embodiment 1
[0032] Embodiment 1: as figure 1 Said, a screening method for personalized scientific research literature, said screening method comprises the following steps:
[0033] 1) Collect 3 keywords in specific fields by researchers, input these keywords on the database and get a large number of scientific articles, then output the title, author and abstract information into a summarized text file, and ask the researchers to provide Read 10 preferred literature in this particular field.
[0034] 2) Remove punctuation marks from each article in the summarized text file, separate the articles into individual words, then calculate the TF-IDF value for all words, and establish a k-dimensional vector representing each article;
[0035] by and Represent the vectors of all articles and user preference references, w is the TF-IDF value of each word and k is the number of words;
[0036] word K i in literature d j Term frequency TF in i defined as ;
[0037] word K i Inverse Docum...
Embodiment 2
[0044] Embodiment 2: as figure 1 and 2 Shown:
[0045] In 2016, there are more than 10,000 related literatures in three distinct research areas: new application of old drugs, pancreatic cancer gene targets and metabolic mechanism of fatty liver. According to the traditional manual search method, it is impossible to complete a comprehensive reading of all literatures Yes, assuming that 5% of the documents are randomly selected for reading, it will take 3-6 months (estimated according to the difficulty of different documents).
[0046] However, searching according to the method of the present invention, we spent about 1 day to complete the comprehensive reading of the literature and recommend personalized scientific research literature. In addition, after perfecting the training data set for 4 rounds, we sampled and read the recommended documents according to the traditional manual reading method for manual judgment, and found that the accuracy rate of the recommended document...
Embodiment 3
[0047] Embodiment 3: as figure 1 and 3 Shown:
[0048] In 2016, there were more than 30,000 related literatures in three distinct research areas: pancreatic cancer new drug trials, hepatotoxic inflammasomes, and cholestasis mechanism. According to the traditional manual search method, it is impossible to complete a comprehensive reading of all literatures. Yes, assuming that 5% of the documents are randomly selected for reading, it will take 6-9 months (estimated according to the difficulty of different documents).
[0049] However, searching according to the method of the present invention, we spent about 6 days to complete the comprehensive reading of the literature and recommend personalized scientific research literature. In addition, after perfecting the training data set for 4 rounds, we sampled and read the recommended documents according to the traditional manual reading method for manual judgment, and found that the accuracy rate of the recommended documents meeting...
