Step 2: Define Imports

In [4]:
import pandas as pd
import numpy as np
import json
import os
import uuid


from sentence_transformers import SentenceTransformer, util
model = SentenceTransformer('all-MiniLM-L6-v2')

import elasticsearch
from elasticsearch import Elasticsearch
from elasticsearch import helpers

from tqdm.auto import tqdm
tqdm.pandas()
In [5]:
df  = pd.read_csv("data job posts.csv")
In [6]:
df.shape
Out[6]:
(19001, 24)
Shows Sample Job Posting
In [7]:
df.head(1)
Out[7]:
jobpost date Title Company AnnouncementCode Term Eligibility Audience StartDate Duration ... Salary ApplicationP OpeningDate Deadline Notes AboutC Attach Year Month IT

1 rows × 24 columns

This is Sample class that will help to convert sentences into Token

In [8]:
class Tokenizer(object):
    def __init__(self):
        self.model = SentenceTransformer('all-MiniLM-L6-v2')

    def get_token(self, documents):
        sentences  = [documents]
        sentence_embeddings = self.model.encode(sentences)
        encod_np_array = np.array(sentence_embeddings)
        encod_list = encod_np_array.tolist()
        return encod_list[0]

Step 3: Creating Tokens

Lets create corups of vectors and use teh power of elastic search to Search vectors with semantics Search

In [10]:
token_instance = Tokenizer()
Converting Job Post into Vectors legth of vector is 382
In [190]:
df = df.head(5000)
df = df.dropna(how='all')
In [191]:
df['vector'] = df['jobpost'].progress_apply(token_instance.get_token)
