The Ultimate Guide to Alternative Data - What Is It Really?

"Where there is data smoke, there is business fire.”— Thomas Redman

The Investment firms and hegde funds have sensed the smoke, now they wisely harness the fire. Data for gaining insights into investment processes no longer rely solely on information published by companies (through cash flows, financial statements, press releases and other macro data like GDP and inflation). The focus has now shifted to the most unlikely of places. Welcome to the world of Alternative data.

What is Alternative Data?

Alternative data is data sourced from outside the company (alternatively through financial transactions, sensors, mobile devices, public records, internet, etc). This data gathered provides unique insights into investment opportunities and offers an advantage for those seeking to outperform others in the market. This data includes; Social Media data, Web browsing data, Mobile App data, Email receipts, Location data, People and company data , Credit card data and the list goes on and on.

Who uses alternative data?

Alternative data is mostly by used hedge funds and investment firms to aid decision making predict economic outlooks. Now there's little or no need of the "gut feeling" for professional investors who would rather make decisions based on actual data. According to Rob Matheson on MIT News, hedging funds could predict REIT values and the economy using location data pulled from mobile devices. Investing analysts, quant traders, and fund managers also use alternative data to guide thforeir algorithms, generating consistently better returns than the broad market.

How do you access alternative data?

Alternative data vendors such as Proxycurl offer alternative data of several types to suit different business purposes.

LinkDB: A comprehensive dataset of public LinkedIn members and companies

Are you aware of how easy it is to automate sales/marketing prospecting and investment analysis on LinkedIn? What if you realized that LinkDB even makes it easier?

LinkDB is an exhaustive dataset of publicly accessible LinkedIn members and companies. The database contains the profiles of 17+M companies worldwide and people's profiles separated by regions. The regions include countries like the United States, Canada, the United Kingdom, Israel, Singapore, Australia, New Zealand, and Ireland. It also has snapshots of other countries too. You can reach out to them to get a breakdown of our people profiles by country.

To access the database you need a basic knowledge of SQL, JSON query functions and operators, and SQL/JSON path expressions. Here is a basic example of how to search users by name.

SELECT
  id,
  parsed_data->>'first_name' AS first_name, 
  parsed_data->>'last_name' AS last_name
  FROM profile
  LIMIT 10;

Visit their documentation if you are interested in finding out more about their search queries, e.g. finding all Apple employees or finding Software Engineers in San Francisco.

I'm sure you'll have used a chat app that allows sending voice messages, but what happens when you don't have enough time to listen to important voice messages or probably you are in a noisy area, would you rather save the voice message for later or you'd prefer to read the text transcribed format?
Or probably the person's accent is quite strange, would you rather hear the audio over and over again or you'll play the audio and easily read along when the word being said is highlighted?

So after imagining this scenario, I taught about creating a chat app that could solve this problem by both transcribing the audio file and highlighting the word being said.

Overview of My Submission

Groupcon is a web application specially designed for group conversations and has different functionalities, one of the major functionality includes sending audio messages and the audio message text transcription.

MongoDB Submission Post E-commerce web application

Overview of My Submission

I implemented the atlas search features three places in the webpage

Home page

I implemented autocomplete features that will enable users search through the name and description, and added some awesome filters.
Note: for search on all product I used Lorem because all the product description are the same so filtering will be easier since I don't have much saved data

const () => {
  console.log('The code is lengthy, you might wanna check the code on github😜')
}

Checkout page

Here I implemented geowithin search to search for pickup store within approximately 3miles from the inserted location.

Note: I added the input for longitude and latitude for testing porposes. It was supposed to get the users current location and search for the nearest store. Currently is not getting the users location because I used a free hosting plan and google map don't work on "non secured" site😢 and also due to the fact that I don't have many saved location data, I added the input field

router.get("/searchstore", async (req, res) => {
    try {
        const arr = req.query.loc.split(",");
        const arrofno = arr.map(a => Number(a));

        let result = await Store.aggregate([
            {
                $search: {
                    index: "storeac",
                    geoWithin: {
                        circle: {
                            center: {
                                type: "Point",
                                coordinates: arrofno,
                            },
                            radius: 5000,
                        },
                        path: "address.location",
                    },
                },
            },
        ]);

        res.send(result);
    } catch (e) {
        if (e) {
            console.log(e);
        }
    }
});

Admin Mail page

Here I repeated the atlas autocomplete search features, and added highlighting for easier referencing.

router.get("/searchmail", async (req, res) => {
    try {
        let result = await Contact.aggregate([
            {
                $search: {
                    index: "contactac",
                    compound: {
                        should: [
                            {
                                autocomplete: {
                                    query: `${req.query.term}`,
                                    path: "username",
                                    fuzzy: {
                                        maxEdits: 2,
                                    },
                                    score: { boost: { value: 3 } },
                                },
                            },
                            {
                                autocomplete: {
                                    query: `${req.query.term}`,
                                    path: "subject",
                                    fuzzy: {

                                    },
                                    score: { boost: { value: 2 } },
                                },
                            },
                            {
                                autocomplete: {
                                    query: `${req.query.term}`,
                                    path: "email",
                                    fuzzy: {
                                        maxEdits: 2,
                                    },
                                },
                            },
                            {
                                autocomplete: {
                                    query: `${req.query.term}`,
                                    path: "message",
                                    fuzzy: {
