从句子中提取艺术家和歌曲标题的技巧？(Techniques to extract artist and song title from a sentence?)

从句子中提取艺术家和歌曲标题的技巧？(Techniques to extract artist and song title from a sentence?)

对于上下文，我要做的是创建一个小的webapp，您可以在其中粘贴Reddit讨论线程，并将线程中引用的歌曲名称转换为Spotify播放列表。

我试图找出一种从某种自然语言中提取艺术家/歌曲名称的方法，格式为“ artist - song name ”或“ songname by artist ”。

所以，例如，假设我有以下字符串：

The Funeral by the Band of Horses is my favorite song. you should check out the Acoustic version of Foo Fighters - Everlong. Eminem- Stan. Not a fan of rap but I like this song.

结果输出将是：

["The Funeral", "the Band of Horses"], ["Foo Fighters", "Everlong"], ["Eminem", "Stan"]

由于没有办法知道什么是艺术家，什么是没有API调用的歌曲，因此不需要以任何特定的方式存储，我只需要将艺术家和歌曲名称分成不同的数组部分。

这可能没有任何分隔符来表示歌曲名称的结尾吗？

这是我到目前为止的...（半伪代码）：

delimiters = [" - ", "-", " by ",]; strings = [ "The Funeral by the Band of Horses is my favorite song.", "you should check out the Acoustic version of Foo Fighters - Everlong.", "Eminem- Stan. Not a fan of rap but I like this song." ]; // loop over each string for (var i=0; i<strings.length; i++ ) { // loop through each delimiter possibility for (var d=0; d<delimiters.length; d++) { if ( strings[i].indexOf(delimiters[d]) > -1 ) { // we have a delimiter match // now figure out how to get the stuff on either side... } } }

For context, what I'm trying to do is make a small webapp in which you can paste a Reddit discussion thread, and have song names referenced in the thread converted into a Spotify playlist.

I'm trying to figure out a way to extract artists/song names from some natural language, in the format of of "artist - song name" or "songname by artist" .

So, for example, say I had the following strings:

The Funeral by the Band of Horses is my favorite song. you should check out the Acoustic version of Foo Fighters - Everlong. Eminem- Stan. Not a fan of rap but I like this song.

the resulting output would be:

["The Funeral", "the Band of Horses"], ["Foo Fighters", "Everlong"], ["Eminem", "Stan"]

Since there's no way to know what is an artist vs. what is a song without an API call, they don't need to be stored in any particular manner, I just need the artist and song name broken into different array parts.

Is this possible to do without any sort of delimiter to indicate the end of a song name?

Here's what I have so far... (semi-pseudo-code):

delimiters = [" - ", "-", " by ",]; strings = [ "The Funeral by the Band of Horses is my favorite song.", "you should check out the Acoustic version of Foo Fighters - Everlong.", "Eminem- Stan. Not a fan of rap but I like this song." ]; // loop over each string for (var i=0; i<strings.length; i++ ) { // loop through each delimiter possibility for (var d=0; d<delimiters.length; d++) { if ( strings[i].indexOf(delimiters[d]) > -1 ) { // we have a delimiter match // now figure out how to get the stuff on either side... } } }

有一个有趣的文本解析库： Knwl.js 。 Knwl.js似乎没有用于解析艺术家或歌曲的插件，但它似乎应该很容易实现。 请参阅： 插件开发

There is an interesting library for text parsing: Knwl.js. Knwl.js doesn't seem to have a plugin for parsing artists or songs, but it seems it should be easy to implement. See: plugin development
