  • You were looking for a change in your job. You started navigating through a job portal. Suddenly, a job description caught your attention.

    It looked like a perfect fit! It seemed that the role was created just for you only! Quickly, you uploaded your resume to apply. You were so sure that you would get a call soon for an interview. But unfortunately, that call never came! Did that ring a bell? Did that happen to you? Well, finding a job is a complex process. There are hurdles at different levels. Sadly, I never realized why I am not getting the first call until a few days back when I called the recruiter immediately after I submitted for a role.

    Then I came to know that our resumes are scanned by an automated NLP program even before reaching a hiring manager or even before catching a human eye. I am sure different companies use resume scanners of different complexities. I want a simple one — my very own resume scanner. So this post is all about creating your own resume scanner — A program to see how well your resume matches a specific job description. Also, I will create a word cloud using the Job description so that we get a clear view of all the important keywords.

    Now, Resumes do not have a fixed file format, and hence they can be in any file format such as. So our first challenge is to read the resume and convert it to plain text. For this, we can use two Python modules: pdfminer and doc2text. These modules help extract text from.

    One to read resumes in pdf file format. Another one to read in. Both of the function will return the text in the Resume. I am always a big fan of Word Clouds. If you are scanning a job description you may miss a few skills that the role demands. May be you have some experience in those skills and did not remember to add in your resume. Thus, a word cloud will flash those keyoword for a quick review.

    To get a score of how the resume matches a specific job description, I am going to use a Cosine Similarity metric. Mathematically, it measures the cosine of the angle between two vectors projected in a multi-dimensional space. The smaller the angle, the higher the cosine similarity. In this context, the two vectors are arrays containing the words of two documents. Now, a commonly used approach to matching similar documents is based on counting the maximum number of common words between the documents.

    But there is a problem with this approach. As the size of the document increases, the number of common words tend to increase even if the documents talk about different topics. Thus, smaller the angle, higher the similarity. Okay, so lets create a function to find the match score!

    I am using my personal resume and copied it in the same folder so that it can be read by this program. Now, let me get a Job Description from a Job portal. What you'll do: The role involves partnering very closely with multiple PMs, Engineers, Test Managers and Business Partner to elevate the site experience for the verticals on Walmart. Analyze click stream data to understand how customers are interacting with the site.

    Uncover user pain points and help in building inspirational experiences. Display dashboards: Visualize data with templated or custom reports. Create effective reporting and dashboards.

    Similarity Scores: Your resume matches about Today, I got an answer for all my speculations. So, the takeaway for today is if a job description looks like a good fit, I need to run this program and check where my resume stands. Thus the resume scanner can tell you a story — a real one! I have uploaded my Jupyter Notebook for resume scanner program in my Github.

    Also, if you are looking for some other project ideas, take a look at my below projects:.

    We show a framework for mining relevant entities from a text resume, and how to separation parsing logic from entity specification. By Yogesh H. Kulkarni Summary This article demonstrates a framework for mining relevant entities from a text resume.

    It shows how separation of parsing logic from entity specification can be achieved. Although only one resume sample is considered here, the framework can be enhanced further to be used not only for different resume formats, but also for documents such as judgments, contracts, patents, medical papers, etc. To make sense of it, one must, either go through it painstakingly or employ certain automated techniques to extract relevant information. Looking at the volume, variety and velocity of such textual data, it is imperative to employ Text Mining techniques to extract the relevant information, transforming unstructured data into structured form, so that further insights, processing, analysis, visualizations are possible.

    This article deals with a specific domain, of applicant profiles or resumes. They, as we know, come not only in different file formats txt, doc, pdf, etc. Such heterogeneity makes extraction of relevant information, a challenging task. Even though it may not be possible to fully extract all the relevant information from all the types of formats, one can get started with simple steps and at least extract whatever is possible from some of the known formats.

    Broadly there are two approaches: linguistics based and Machine Learning based. Framework A primitive way of implementing entity extraction in a resume could be to write the pattern-matching logic for each entity, in a code-program, monolithically.

    This makes maintenance cumbersome as the complexity increases. To alleviate this problem, separation of parsing-logic and specification of entities is proposed in a framework, which is demonstrated below. Entities and their RegEx patterns are specified in a configuration file. The file also specifies type of extraction method to be used for each type of the entity. Parser uses these patterns to extract entities by the specified method.

    Entities Specification The configuration file specifies entities to be extracted along with their patterns and extraction-method. It also specifies the section within which the given entities are to be looked for.

    Specification shown in the textbox below, describes meta data entities like Name, Phone, Email, etc. Entities like Email or Phone can have multiple regular-expressions patterns. If first fails then the second one is tried and so on. Phone: Optional International code in bracket, then digit pattern of , with optional bracket to the first 3 digits. Once an entity is matched it is stored as the node-tag, like Email, Phone, etc. It finds value within a section just by matching given words.

    Segmentation The sections mentioned in the above code snippets are blocks of text, labelled such as SummarySection, EducationSection, etc. These are specified at the top of the config file. Sections are recognised by keywords used for its headings. Once the new heading matches, the new state of the next section starts, so on. Results A sample resume is shown below: Entities extracted are shown below: Implementation of the parser, along its config file and sample resume can be found at github.

    End note This article demonstrates unearthing of structured information from unstructured data such as a resume. As the implementation is shown only for one sample, it may not work for other formats. One would need to enhance, customize it to cater to the other resume types. Apart from resumes, the parsing-specifications separation framework can be leveraged for the other types of documents from different domains as well, by specifying domain specific configuration files.

    Bio: Yogesh H. Kulkarni , after working in the field of Geometric Modelling for more than 16 years, has recently finished a PhD in it. He got into Data Sciences while doing the doctoral research and wishes to pursue further career in it now.

    He would love to hear from you about this article as well as on any such topics, projects, assignments, opportunities, etc.

    Entities like Email or Phone can have multiple regular-expressions patterns. A key concept behind this method is discriminative fine-tuning, where the different layers of the network are trained at different rates.

    BERT — Bidirectional Encoder Representations from Transformers: a modification of the Transformer architecture by preserving the encoders and discarding the decoders, it relies on masking of words which would then need to be predicted accurately as the training metric.

    It discarded the encoders, retaining the decoders and their self-attention sublayers. Recent years have seen the most rapid advances in the NLP field. This is a big step towards the full democratization of NLP, allowing knowledge to be re-used in new settings at a fraction of the previously required resources. Source Why should you build NLP projects? NLP is at the intersection of AI, computer science, and linguistics.

    It deals with tasks related to language and information.
