What this technology can do (for business/apartment owners and for travelers)

1. AI-powered new analytical dashboards (for business owners)

1.1. Automatic Conversion of Reviews into Recommendations/Tickets/Tips (for Business Owners)

First, you process all reviews of a given apartment and extract important information with high accuracy. Then, it is easy to compare these results with other apartments, and valuable patterns emerge.

Our AI deeply analyzed all 587 of your reviews, compared with 250 000 reviews of similar businesses and extracted 9 Recommendations/Tips how you can improve your business:

  • Consider providing keys at the location, people will save time (11% complained in reviews - compared to 2.5% average) - read more and see reviews...
  • Repair broken things in the apartment (7% complained) and Update/Buy new furnitures (5% complained) - read more and see reviews...
  • Consider improving the speed of the WiFi (9% complained) and repair issues with WiFi (7% complained) - read more...
  • Guests would appreciate complementary snacks/food read reviews of how a similar business do it...
  • Try to be more friendly to your clients (7% complained) and respects more of their privacy (3% complained) - read more and see reviews...
Extract more Recommendations from Reviews...

Compare your parameters with similar businesses

1.2. Human-like (Semantic) classification of reviews (for Business Owners)

Here, we focused on showing classified negative opinions critical to apartment owners and presented on a brand reputation dashboard.

By clicking on specific semantic category (here: Noisy rooms) we get specific sentences/segments and "not the whole review" where people mentioned noisy rooms. We detect all the information that is correlated to noisy rooms (e.g. cleaner is banging around), not just with keywords (e.g. noisy, loud). This is the advantage if you use Human-like Analysis (Semantic Analysis) instead of keywords.

2. AI powered travel search & discovery & chatbots (for travelers)

2.1. Travel Hotel/Accommodation Search personalization (for Travelers)

Search based on your individual preferences matched with opinions of similar people to you and data from reviews

What is important to you? Personalize your search

Our AI remember these parameters while reading millions of reviews and find you the best possible place

  • Friendly, Well-informed Host
  • Cozy apartment, nice atmosphere
  • Fast WiFi, everywhere
  • Host responses quickly
  • Keys at the location
  • Handicap accessible & Elevator available
  • No hidden fees, No deposit, No problem with Refunds
  • Garden/Terrace available
  • Private Bathroom
  • Host respects privacy
  • more...
  • Recommended for (based on reviews)
    Solo, With children, Business trip, Romantic trip, Quiet stay, Pet-friendly
  • Close to (based on reviews)
    Restaurants, Local Attractions, Airport, Highway,
    Public Transport., Beach, Shopping, City center, Nature

Our AI deeply analyzed 3 million reviews from Berlin to match your personal needs:

2.2. Travel chatbot fueled by reviews - Automatic learning of information and users opinions from reviews and using it in conversation.

Meet the Alchemist Traveler. He has been everywhere and he has read all reviews in the world (and he remembers them all).
He is patient and he can spare a moment to plan your perfect vacation.

Example 1:

Where are you going?
Great, please describe what it is important to You or select by tapping on the screen
working free wifi, working pool, pet friendly and no smelly rooms
Good choice! I have just analyzed 3 millions (wow! right?) reviews against your needs and I found 17 places.

Example 2:

Where are you going?
What is important to You?
I don’t like dogs, children, need elevator
Got it! Something more?
no hidden fees and deposits
I have just analyzed 3 millions (wow! right?) reviews against your needs and I found 12 places.

Example 3:

You selected Hotel A in Barcelona, do you have some questions about it?
oh yes, very important, is it handicap friendly for real?
Yes, 24 guests stated in reviews that it is handicap friendly, do you want to see specific sentences from reviews of that guests?
yes please
“i was satisfied that elevator was working properly because I was with my eldery aunt”, “staff of the hotel take very good care of my old papa”, bathroom was handicap accessible!”
great, book it!

2.3. Human-like (Semantic) summary of reviews (for Travelers)

Instead of reading thousands of reviews individually, you can see a semantic summary and get a feeling for what is contained within them in 20 seconds. You can click for specific information and see extracted sentences from reviews.

3.3. AI powered Automatic Review Report Generation (for travelers&business owners)

Information extracted by 130 Semantic Models is precise enough to create automatic text summary.

Natural Language Generation Summary from Reviews could look like this:

Our AI deeply analyzed all your reviews for the past 3 months, combined them with reviews of similar businesses and created this summary:

Most of people (88%) was satisfied with their stay, a lot of people (47 mentions) wrote that they would come back and will recommend this apartment (24 m.).

Reviewers state that rooms in this apartment are clean (34 mentions) and spacious (22 m.) and kitchen has all the amenities (15 m.). They also were satisfied with garden (17 m.) and the terrace (15 m.).
The majority found the host helpful and friendly (35 m.) but some stated that they were unprofessional (19 m.). People also complained about the slow check-in process (20 m.) and that the keys were not at the location (11 m.).

There were also some issues with the Neighbors (23 m.) and loud noises at the night (17 m.).

Generally, people say it is a good value for money (42m.). Some said it is expensive (9 m.) but also some said it is cheap (14 m.)

How it works on a single review

Example apartment review:

We got this apartment because of its cheap price and near to the centre. The bedroom was a little bit small and the bed was not that comfortable. There was a lot of lovely decorations and it was nice. There was very fast wifi, which was great. However there was no parking spaces in front of the house so we spend some time sechrching for a place. Also the neigherhood was full of drunken people, probably it was because the house was not that far from downtown and beach and there was a lot of homeless people Will not come back.

Live Demo and Comparison with other technologies

How we differ?

We specialize in creating dedicated Natural Language Understanding engine for specific reviews. We focused in travel and prepared a set of products to process many different travel reviews (e.g. hotel, hostel, apartment, restaurant, airline reviews).

We stand by the statement that we detect more information than Watson or than any other Deep Learning solution and we are more accurate than Google in Travel Domain. We are also much more cost-effective. And we allow the processing of as much data as you want with no additional cost (0 cents / text).

This is possible because we created the next-generaion process of developing NLU systems in which we can build Semantic Models 10 x faster. It is designed from the ground up to process reviews, not proper english texts. It is the result of 12 years of experience in NLP/NLU and 8 years in processing reviews, and more than 50 big implementations (2007-2019) of NLU systems to process reviews and other user generated content.

We are passionate and proud of our technology and aim to provide the optimal technology for travel reviews. We will be happy to help you implement your brilliant ideas and discover what is possible.

1. Sentiment Analysis & Concept/Keyword/Topic Analysis - Current tech available

"Breakfast was tasty" => Breakfast: positive
"Breakfast was huge" => Breakfast: positive
"Breakfast was not free" => Breakfast: negative
"Breakfast was very tasty but really small" => Breakfast: neutral
"Breakfast was huge but you had to pay extra" => Breakfast: neutral

2. Human-like Analysis (AI In-the-Box) - Unicorn NLP

"Breakfast was tasty" => Breakfast: tasty
"Breakfast was huge" => Breakfast: big portions
"Breakfast was not free" => Breakfast: free
"Breakfast was very tasty but really small" => Breakfast: tastysmall portions
"Breakfast was huge but you had to pay extra" => Breakfast: big portionsnot free

Language has colors. Do not reduce it to Black & White.

Technological differences (compared to other NLP/NLU solutions):

  • High Resolution/depth of output, richness of output, what different type of information we capture out of reviews - state-of-the-art: 124 detailed Semantic models
  • Very high Fact Coverage (state-of-the-art: 90%) - percentage of pertinent information we extract from reviews
  • Very high, Human-like Accuracy - state-of-the-art F1: precision=90-95%, recall=70-85%
  • Detailed and easy-to-use Semantic models (e.g. comfy room, spacious room, tasty breakfast, will come back) instead of statistical models (e.g. room - confidence: 0.84623) or grammatic models (e.g. NS, VP, ADV)
  • Very fast! We are much much faster than any deep learning or any other solution. Highly optimized technology was very important for us from the beginning. To show you how much, take this example: On a Amazon AWS medium-cpu instance we process up to 1 million reviews a day.

Other differences:

  • You can get the on-premise version with no maintanance fees and 0 cents/text
  • No linguistic or machine learning expertise required to implement it into your product/system! Output is simple enough to be used by anyone and even simple enough to be displayed to the user directly (no post-processing needed, no configuration required, most solutions can be implemented in days)
  • All data extracted by our tech makes sense - we do not provide hard to understand keywords with confidence and some of them do not make sense. Each Semantic Model is actionable data (tasty breakfast, wifi does not work, staff was unfriendly, elevator not working, etc.). Each Semantic Model was built and tested on hundreds of thousands of hotel reviews. Each Semantic model consist of between a hundred and a thousand of ways to express concrete situation. That is why you do not have to configure it to your data.

What is a Semantic Model

The semantic model is the newest approach to an information extraction models where boundaries of those models are not determined by the structure of a language (or grammar, or used words), but the type of information you are detecting. It does not matter how the user writes an opinion about a specific object, e.g. “breakfast was a joke”, “Muffin and cold coffee is not a breakfast”, “Breakfast wasn’t included as written”, our semantic model still detects it and provides structured-data. With "breakfast" example, it is relatively easy to provide a shallow analysis (e.g. Sentiment Analysis) with the current NLP techniques. If you are looking for more sophisticated information (e.g. is it safe?, is it handicap friendly?, will someone come back?, Is it sustainable? Is it pet-friendly?) the situation gets more complicated. Current techniques provide a part of this information and their accuracy relies on the keywords used in reviews. Users are very creative in the reviews and they are not using a keyword approach. Let’s take one example. If we want to answer the question “is it safe?”, you need to capture a lot of information from reviews without common keywords safe/dangerous. In practice they write this in tens or hundreds of ways: e.g. “there was a lot of drunken people outside”, “I did not feel good because of the neighbors”, “someone yelled in the night and the front desk lady did nothing”. We believe, that if the human can understand what is written in the review, then technology should detect it as well. That is why we call them Semantic Models, not information extraction models.

Where are we making these Semantic Models

Our UnicornNLP Semantic Environment is a place where we design and precisely craft all the semantic models. It is a perfect combination of human and computer intelligence. It is the secret sauce of our technology and it allows us to deliver the best technology in the world for reviews. Statistical algorithms provide the data based on the processing of hundreds of thousands of reviews, but the humans are making all the crucial decisions. Given the pace of AI development, this is significant advantage in information extraction (in NLP/NLU) and it will be appropriate for the next decade. Think about our environment as a way of creating tens of thousands of very precise, hand-crafted semantic rules but with an AI as an assistant that is generating new ideas. These ideas are provided by an AI assistant based on constant simulations on real data and statistical tools.

We designed a semantic programming language (QL4Reviews) to extract information from reviews. With this programming language, you build semantic models 10 times faster than in other current technologies. Every Semantic Model is programmed in QL4Reviews and consist of 50-2000 lines of semantic code. Heavily optimized engine allow to process through 124 Semantic Models on 1 low-cpu Amazon AWS instance - 1 million reviews a day. Speed of the core engine was very important for us from the beginning.

How to process non-English Reviews

Our technology is designed from the ground up to process reviews, not proper-grammar texts. It can process also machine-translated reviews/texts (via Google Translate or Microsoft Translate). This approach provides almost as good results as processing English reviews but we do not have to rewrite deep semantic models into other languages. It is much easier to maintain and scale (because there is only 1 engine).

Are we another NLP API for Travel?

This is not just another NLP API/Tool. We redesigned every layer of technology and we wanted to address the biggest challenge in the NLP/NLU industry. We wanted to change the way you use and think about Natural Language Understanding API. In our opinion, if you are using NLP API, you should not get your hands dirty and spend inordinate time thinking how to best implement this API into your application. We wanted to hide all the NLP complexity inside the system and provide you ready-to-use data. We believe that NLP API should be simple and easy to use without linguistic, machine learning or other expertise. You do not need to spend weeks to improve the accuracy of "domain-indepentent" NLP API, to adjust to Your domain or to make decisions about complex output parameters. Getting output parameters like confidency (e.g. 0.7852) or polarity (e.g. 0.4352) or keywords detected (e.g. friendly, 0.6786; dissapointed, -0.7564) gives every developer problems and frankly they are not standard or predictable. They are rather a consequence of used technology inside, and putting these parameters for the output in our opinion is the way to leave configuration and responsibilty for decision-making to You. We believe in human-like output where a human can understand what this API detected. We believe that we have developed excellent API for specific domains, so you can get tailored results and focus on your business. We position ourselfes as a read-to-use technology, not a standard API that is a tool that you need to configure and train to your data.
