Python在学术上匹配论文ID

Question

我有一份谷歌学者论文的作者名单：Zoe Pikramenou、James H.R.Tucker、Alison Rodger、Timothy Dafforn。我想摘录并打印至少3篇论文的标题。

您可以使用学术词典从每位作者处获取论文信息：

from scholarly import scholarly
AuthorList = ['Zoe Pikramenou', 'James H. R. Tucker', 'Alison Rodger', 'Timothy Dafforn']
for Author in AuthorList:
    search_query = scholarly.search_author(Author)
    author = next(search_query).fill()
    print(author)

输出看起来像（只是从一个作者那里得到的一小部分摘录）

                  {'bib': {'cites': '69',
         'title': 'Chalearn looking at people and faces of the world: Face '
                  'analysis workshop and challenge 2016',
         'year': '2016'},
 'filled': False,
 'id_citations': 'ZhUEBpsAAAAJ:_FxGoFyzp5QC',
 'source': 'citations'},
                  {'bib': {'cites': '21',
         'title': 'The NoXi database: multimodal recordings of mediated '
                  'novice-expert interactions',
         'year': '2017'},
 'filled': False,
 'id_citations': 'ZhUEBpsAAAAJ:0EnyYjriUFMC',
 'source': 'citations'},
                  {'bib': {'cites': '11',
         'title': 'Automatic habitat classification using image analysis and '
                  'random forest',
         'year': '2014'},
 'filled': False,
 'id_citations': 'ZhUEBpsAAAAJ:qjMakFHDy7sC',
 'source': 'citations'},
                  {'bib': {'cites': '10',
         'title': 'AutoRoot: open-source software employing a novel image '
                  'analysis approach to support fully-automated plant '
                  'phenotyping',
         'year': '2017'},
 'filled': False,

我如何收集四个作者中有三个或更多的论文的bib，特别是title？

编辑：事实上，有人指出，id\u引文对每一篇论文都不是唯一的，我错了。最好只使用标题本身

Answer 1

首先，让我们将其转换为更友好的格式。您说，id\u引文对于每篇论文都是唯一的，因此我们将使用它作为哈希表/dict键。

然后，我们可以将每个id_citation映射到它所显示的bib判决和作者，作为元组（bib，author_name）的列表。

author_list = ['Zoe Pikramenou', 'James H. R. Tucker', 'Alison Rodger', 'Timothy Dafforn']
bibs = {}
for author_name in author_list:
    search_query = scholarly.search_author(author_name)
    for bib in search_query:
        bib = bib.fill()
        bibs.setdefault(bib['id_citations'], []).append((bib, author_name))

此后，我们可以根据附加的作者数量对bibs中的键进行排序：

most_cited = sorted(bibs.items(), key=lambda k: len(k[1]))
# most_cited is now a list of tuples (key, value)
# which maps to (id_citation, [(bib1, author1), (bib2, author2), ...])

和/或将该列表筛选为只有三个或更多外观的引用：

cited_enough = [tup[1][0][0] for tup in most_cited if len(tup[1]) >= 3]
# using key [0] in the middle is arbitrary. It can be anything in the 
# list, provided the bib objects are identical, but index 0 is guaranteed
# to be there.
# otherwise, the first index is to grab the list rather than the id_citation,
# and the last index is to grab the bib, rather than the author_name

现在我们可以从那里检索论文的标题：

paper_titles = [bib['bib']['title'] for bib in cited_enough]

Answer 2

扩展我的评论，您可以使用Pandas groupby实现这一点：

import pandas as pd
from scholarly import scholarly

AuthorList = ['Zoe Pikramenou', 'James H. R. Tucker', 'Alison Rodger', 'Timothy Dafforn']
frames = []

for Author in AuthorList:
    search_query = scholarly.search_author(Author)
    author = next(search_query).fill()
    # creating DataFrame with authors
    df = pd.DataFrame([x.__dict__ for x in author.publications])
    df['author'] = Author
    frames.append(df.copy())

# joining all author DataFrames
df = pd.concat(frames, axis=0)

# taking bib dict into separate columns
df[['title', 'cites', 'year']] = pd.DataFrame(df.bib.to_list())

# counting unique authors attached to each title
n_authors = df.groupby('title').author.nunique()
# locating the unique titles for all publications with n_authors >= 2
output = n_authors[n_authors >= 2].index

这发现了202篇论文，其中有2位或更多的作者在该列表中（在774篇论文中）。以下是一个输出示例：

由于所有数据都在Pandas中，因此您还可以探索每篇论文的附加作者以及您在作者中可以访问的所有其他信息。出版物array来自学术界。
