Use Case: Investment Opportunities Discovery with AI
Information sourcing and research is a common problem
for many companies out there.
Obtaining useful information about market opportunities from huge amounts of data require vast resources, both in terms of time and funds. The good news is there is the AI-based technology that is able to perform some parts automatically, and therefore improve the efficiency of the whole process.
A system using AI algorithms – Document Classification, Named Entity Recognition, to name a few – can spot certain changes on the market without human intervention.

In order to build the system, we used over 1,000 of different data sources that generated over 10,000 of new tweets/posts, most of which were not in English. To bypass that, we integrated the Google Translate API (a state-of-the-art solution for translation) into the system.
Subsequently, we created a vector representation of every article based on Stanford GloVe embedding that was then used to train a 1D Convolutional Neural Network. Given a new post, the network returns a relevance score. We created a web app that scrapes posts from the selected date and lists posts from the most to the least relevant ones.
By using the above state-of-the-art Natural Language Processing techniques, we managed to detect 95% of relevant posts and thus largely reduce the number of posts from the web that the investors need to review.
Solution: Detecting Company Management Structure Changes
Let’s focus on a particular, real-life example.
An investor needed information about changes in the management structure of companies in NYSE. Before leveraging the AI solution, he employed a dedicated team of research analysts traversing thousands of web articles, tweets and social media posts looking for recent changes in the structure of the companies.
1. Collect the data from the online and local sources
The first step we need to do is to aggregate data from the valuable sources. So far, our client’s analysts read online business newspapers and monitored selected Twitter accounts looking for structural change information.
Our system has entirely automated that work by scraping newspapers and tweets, producing a steady feed of information ready to use by the analysts, putting the information in one place.
2. Filter out the irrelevant materials
As the next stage in the pipeline, our state-of-the-art AI text classification algorithms precisely filter out all the irrelevant materials, basing their judgment on the context and actual meaning of the text.
3. Extract knowledge from text
We’ve already managed to save a lot of time by showing only the most valuable information.
However, there’s still a lot of work to do. Working on raw documents is hard. We need to extract the information that the client needs.
And AI helps us in that as well!
Data scientists call this technique named entity extraction. It identifies important information to the investor in the text, based on given criteria. In this case, we extract the company name, position, and the reason, and put it in a table row that we can use later.
At this point, it can be exported into JSON or CSV.
4. Generate insights and find correlations in the data
You probably know that the computer is great in processing tabular data, like Excel tables or databases. We call this type of information structured data.
The AI now further processes this data by:
prioritizing the most important structural change instances
filtering out based on certain criteria (e.g. companies outside a geographical region)
finding patterns and correlations in data
using the collected information to predict other changes in the market and stock movements (generate insights)
5. Generate a human-sounding, readable report
Our investor needs human-like, readable reports that he/she can easily relate to and quickly find important information.
Thanks to another technology called the Natural Language Generation (NLG), the artificial intelligence can generate human-sounding reports and summaries.
And we’re going to leverage this new machine skill to help our investor.
Our last step is to turn the raw table into an executive summary that the client can use to guide their further decisions.
Integrating all that goodness into the corporate workflow
We’ve made the NLP technology very accessible.
