我需要能够从Excel CSV文件中选择关键字,我已将文件附加到列表中。该程序是一个电话故障排除,我需要输入(“屏幕不会打开”)输出相同的输出(“显示为空白”)。
import {Injectable} from '@angular/core';
import {Http, Response, Headers, RequestOptions} from '@angular/http';
import {Observable} from 'rxjs/Observable';
@Injectable ()
export class StructureRequestService {
result: Object;
//private myUrl = 'http://manny.herokuapp.com/audit/get/structure';
private myUrl = './app/home/nodes.json'; // local URL to structure APi
constructor (private http: Http) {
//use XHR object
let _build = (<any> http)._backend._browserXHR.build;
(<any> http)._backend._browserXHR.build = () => {
let _xhr = _build();
_xhr.withCredentials = true;
return _xhr;
};
}
sendRequest() {
let body = JSON.stringify({});
let headers = new Headers({ 'Content-Type': 'application/json'});
let options = new RequestOptions({
headers: headers
});
this.http.get(this.myUrl, options)
.map((res: Response) => res.json())
.subscribe(res => {this.result = res;
return this.result; });
}
}

您是否正在尝试构建关键字字典或重新发现句子问题? 在这两种情况下,您都需要将问题与关键字相关联。
获取关键字的基本方法是将单词分成单词(使用s.split())并使用最常用的更新关键字列表... difflib可以在这里提供帮助。
由于我们不知道给定的文件架构,我认为它只是一个句子列表,您在其他地方提供了关键字/问题(情况Dict)。
例如:
csv_ret = ["I can't turn on my phone", "The screen won't turn on", "phone The display is blank"]
situations = {
"screen": ["turn on", "blank", "display", "screen"],
"battery": ["turn on", "phone"]
}
def get_situation_from_sentence(sentence):
occurences = {}
for word in sentence.split():
for key, value in situations.items():
if word in value:
if occurences.get(key) is None:
occurences[key] = [word]
elif word not in occurences.get(key):
occurences[key].append(word)
averages = {k: ((len(v) * 100) / len(situations[k])) for k, v in occurences.items()}
return "{}, {}".format(averages, sentence)
for sentence in csv_ret:
print(get_situation_from_sentence(sentence))
结果:
{&#39;电池&#39;:50.0},我无法打开手机
{&#39;屏幕&#39;:25.0},屏幕无法启动
{&#39;屏幕&#39;:50.0,&#39;电池&#39;:50.0},手机显示屏空白
此代码以百分比形式评估句子问题和相关关键字匹配。
这又是一个非常基本的解决方案,你可能需要更强大的东西(词法分析器/解析器,机器学习......)但有时候更简单更好:)
