OUTLINE Introduction Existing System Existing Work (Research) Lacking of existing systems Format of Job and Resume Our Approach System Component Evaluation Job Analytics Future Works

J OB MATCHING A search engine that takes user input (i.e. job title, company name, qualification etc.) and suggests him/her the recommended job. User input Resume Job Postings Keyword

E XISTING SYSTEM There are multiple job searching websites like  Glassdoor  Monster  Indeed But very few support for resume searching Indeed

E XISTING SYSTEM

EXISTING SYSTEMS

E XISTING SYSTEM

E XISTING WORK (R ESEARCH ) Collaborative filtering [1] Critically dependant on the availability of high- quality user profiles Quite rare in the real world scenario Content based filtering [2] Highly dependent on user interaction

LACKING FEATURES Absence of personalization No support for user preference (i.e. New job seekers tend to put more on their educational qualification than experience in a resume) Absence of resume and job dynamics Keyword/term correlated experience and expertise searching. There is no way to search for a job using your entire skill set and experience

SOLUTION ●Personalized Job Matching System ○Crawl resume ○Compare against a continuously-growing database of job-postings across multiple sites and companies ○SQL commands to explore the nature of the data and find patterns ●Prototype an Economic Job Graph

O UR A PPROACH : KEY FEATURES A specialized search engine Full text resume and job search User control over the field Aspect based (keyword based) experience correlation Job prediction

O UR A PPROACH : S YSTEM COMPONENTS As a specialized search engine we have the following components Crawler Doc Analyzer Indexer Ranker Interface Evaluation

C RAWLER (C OLLECTION OF DATA ) Problem  No benchmark job postings data set  No benchmark resume data set  Scarce resource of resume! Solution  Crawler  We have to build specialized crawler for different employer and resume websites  3 different crawler for job posting: Google, Facebook and IBM  1 crawler for resume: indeed.com

D OC ANALYZER Lets take a look in job postings : BA/BS -> Bachelor of Arts/Science MS - > Master of Science Solution: Dictionary Expansion Unix/Linux Data Structure Algorithm Software design Object oriented skills Javascript Network programming How to identify these?

D OC ANALYZER ( CONTD.) Problem: Can we identify the keywords from the open unstructured text? Solution 1: Unigram model Problem: keywords: Software Design becomes Software -> less important than Software Design Design -> less important than Software Design Solution 2: Phrase Query Problem: How to make phrase query when your input is a complete resume?

D OC ANALYZER ( CONTD.) Our observation:  Most of these keywords are Noun  Most of these keyword appears only after some preposition (in, with)  For multiple word keyword (i.e. Software Design) search for consecutive Noun.  Use of Parts of Speech Tagger Results are quite fascinating, we have got most of the meaningfull keywords.

D OC A NALYZER ( CONTD.) Take a look again on a job postings Question: Suppose you have all the qualifications, but not 4 years of experience, where should a job search engine rank this result?

D OC A NALYZER ( CONTD.) Can we indentify keywords oriented experience list for a job postings (or resume) like below? We already have the keywords list!!. Just simply find out the year of experience using the parts of speech tagger and some heuristics. KeywordsExperience C++, Java2 years Software Development5 years TCP/IPNot necessary ….…

INDEXER Two indexers  Job Posting  Resume Job Posting Indexer  Job Title  Job Location  Job Qualification  Job responsibilities  Job keywords (Processed from Data Analyzer)  Job experience (Processed from Data Analyzer)

I NDEXER (CONTD) Two indexer  Job Posting  Resume Resume Indexer  Resume Title  Educational Information  Experience  Additional information  Resume keywords (Processed from Data Analyzer)  Resume experience (Processed from Data Analyzer)

I NDEXER (CONTD) During Index time Document Booster  Documents matching perfectly with query for keywords and experience fields, receives higher score except title.  Ultimately these will help us in ranking the matched document in upper position.

Q UERY PROCESSING Since we have two indexers, we have two types of query  Job postings (search in resume index)  Resume (search in job posting index) Input from the users  We take HTML form based input from the users Query Processing  Perform the same steps of Doc Analyzer

R ANKING & RETRIEVAL During Index time Document Booster  Documents matching perfectly with query for keywords and experience fields, receives higher score except title.  Ultimately these will help us in ranking the matched document in upper position. Document Scoring Function: TF-IDF, BM 25

S YSTEM DESIGN Backend design: Run as a service on Apache Tomcat server 6.0 Java Client Connectivity: Java Server Page (JSP) Front End Design: HTML

DEMO System Demo

EVALUATION o Evaluate the performance we choose ● Mean Average Precision (MAP) o Evaluate Methodologies ● Resume selection: We carefully identify 2 resumes from our dataset. ● Job postings selection: Then we carefully labeled 10 job postings as relevant to those selected 2 resumes ● Mixed up these relevant job postings with some more 20 randomly picked job postings from data set. ● Then calculate the MAP of our System using the top 5 results and find out the MAP but traditional systems have only

J OB PREDICTION Until now we have performed two types of searching: For a given input Resume, perform search on the job posting index For a given input Job posting, perform search on the resume index Can we do something more using exiting resources?

J OB PREDICTION (CONTD.) Perform Resume search on the Resume index. Why? Intuition: People with similar looking resume might be eligible for similar job !! Methods: Find similar resumes Find the companies in those resumes Recommend those companies

JOB ANALYTICS Goals: ●How fast are jobs being filled? ●How fast are jobs being posted? ●When is the best time to apply? Filled Positions:

JOBS IN THE USA

WORLDWIDE JOBS

PROGRAMMING LANGUAGES Facebook: 92.3% IBM: 23.9% Google: 5.8%

F UTURE WORK  Resume Feedback Suggestions  What skills or experience do you need to be qualified for a certain job?  Discover Patterns in Job-Hunting Seasons  What time of year are jobs posted most frequently?  Build a Personal Database  Receive notifications of job posts that match your interests and skill level
