spaCy中有没有打印出最相似句子的功能？

Question

我有一个包含 10 部电影简介的 txt 文件。我有一个单独的绿巨人电影概要，存储为变量中的字符串。我需要将这 10 个概要与绿巨人的概要进行比较，以找到最相似的电影来推荐。我的代码如下：

import spacy

nlp = spacy.load('en_core_web_lg')

hulk_description = """Will he save their world or destroy it? When the Hulk becomes too dangerous for the
Earth, the Illuminati trick Hulk into a shuttle and launch him into space to a
planet where the Hulk can live in peace. Unfortunately, Hulk land on the
planet Sakaar where he is sold into slavery and trained as a gladiator."""

hulk = nlp(hulk_description)

movies = []

with open('movies.txt', 'r') as f_in:
    for line in map(str.strip, f_in):
        if not line:
            continue
        tmp = line.split()
        movies.append(line)

for token in movies:
    token = nlp(token)
    print(token.similarity(hulk))

所以这是有效的，它打印出以下内容：

0.9299734027118595
0.9045154830561336
0.9248706809139479
0.6760996697288897
0.8521583959686228
0.9340271750528514
0.9251483541429658
0.8806094116148976
0.8709798309015676
0.8489256857995392

我可以看到第 6 部电影的概要最相似，为 0.9340271750528514。但我的问题是； spaCy 中是否有一个函数可以让我在完成比较后只打印出最相似的句子？即我基本上想比较所有这些，然后通过显示其概要来推荐最相似的电影。

Answer 1

尝试使用这个：

max((nlp(token).similarity(hulk), token) for token in movies)

Answer 2

您可以尝试通过 nlp.pipe 生成器传递字符串和电影来计算其相似度：

import spacy

nlp = spacy.load('en_core_web_md')

hulk_description = """Will he save their world or destroy it? When the Hulk becomes too dangerous for the
Earth, the Illuminati trick Hulk into a shuttle and launch him into space to a
planet where the Hulk can live in peace. Unfortunately, Hulk land on the
planet Sakaar where he is sold into slavery and trained as a gladiator."""

hulk = nlp(hulk_description)

movies = ["this is a movie", "this is another movie about Hulk"]

sims = []
for movie in nlp.pipe(movies):
    sims.append(hulk.similarity(movie))
    
id_max = np.argmax(sims)
print(movies[id_max])
# this is another movie about Hulk

Is there a function to print out the most similar sentence in spaCy?

python

nlp

spacy

sentence-similarity
