Liferay DXP has become a widely adopted portal platform for building and managing advanced digital experiences over recent years. Organizations use it for intranets, customer portals, self-service platforms, and more. While Liferay DXP is known for its user-friendliness, its default search functionality can be further optimized to meet modern user expectations. To address this, ACA developed an advanced solution that significantly enhances Liferay’s standard search capabilities. Learn all about it in this blog. Searching in Liferay: not always efficient Traditionally, organizational searches relied on individual keywords . For example, intranet users would search terms like "leave" or "reimbursement" to find the information they needed. This often resulted in an overload of results and documents , leaving users to sift through them manually to find relevant information—a time-consuming and inefficient process that hampers the user experience. The way users search had changed The rise of AI tools like ChatGPT has transformed how people search for information. This is also visible in online search engines like Google, where users increasingly phrase their queries as complete questions. For example: “How do I apply for leave?” or “What travel reimbursement am I entitled to?” To meet these evolving search needs, search functionality must not only be fast but also capable of understanding natural language. Unfortunately, Liferay’s standard search falls short in this area. ACA develops advanced AI-powered search for Liferay To accommodate today’s search behavior, ACA has created an advanced solution for Liferay DXP 7.4 installations: Liferay AI Search . Leveraging the GPT-4o language model , we’ve succeeded in significantly improving Liferay’s standard search capabilities. GPT-4o is a state-of-the-art language model trained on an extensive dataset of textual information. By integrating GPT-4o into our solution, we’ve customized search algorithms to handle more complex queries , including natural language questions. How does Liferay AI Search work? Closed dataset The AI model only accesses data from within the closed Liferay environment. This ensures that only relevant documents— such as those from the Library and Media Library—are accessible to the model. Administrators controls Administrators can decide which content is included in the GPT-4o dataset, allowing them to further optimize the accuracy and relevance of search results. Depending on the user’s profile, the answers and search results are tailored to the information they are authorized to access. Direct answers Thanks to GPT-4o integration, the search functionality provides not only traditional results but also direct answers to user queries. This eliminates the need for users to dig through search results to find the specific information they need. The comparison below illustrates the difference between search results from Liferay DXP’s standard search and the enhanced results from ACA’s Liferay AI Search.

ACA Group Team

November 30, 2023 marked a highly anticipated day for numerous ACA employees. Because on Ship-IT Day, nine teams of ACA team members, whether or not supplemented with customer experts, delved into creating inventive solutions for customer challenges or for ACA Group itself. The hackathon proved to be both inspiring and productive, with at the end a deserved winner! The atmosphere in the ACA office in Hasselt was sizzling right from the early start. Eight out of the nine project teams were stationed here. During the coffee cake breakfast, you immediately felt that it was going to be an extraordinary day. There was a palpable sense of excitement among the project team members , as well as a desire to tackle the complex challenges ahead. 9 innovative projects for internal and external challenges 🚀 After breakfast, the eight project teams swarmed to their working habitat for the day. The ninth team competed in the ACA office in Leuven. We list the teams here: Chatbot course integration in customer portal System integration tests in a CI/CD pipeline Onboarding portal/platform including gamification Automatic dubbing, transcription and summary of conversations publiq film offering data import via ML SMOCS, Low level mock management system Composable data processing architecture Virtual employees Automated invoicing If you want to know more about the scope of the different project teams, read our first blog article Ship-IT Day 2023: all projects at a glance . Sensing the atmosphere in the teams Right before noon, we wondered how the teams had started and how their work was evolving. And so we went to take a quick look... 👀 1. Chatbot course integration in customer portal “After a short kick-off meeting with the customer, we divided the tasks and got to work straight away,” says Bernd Van Velsen. “The atmosphere is great and at the end of the day, we hope to present a result that will inspire the customer . In the best case, we will soon be able to use AI tools in a real customer project with the aim of making more optimal use of the customer's many data.” “The Ship-IT Day is an annual tradition that I like to participate in,” says Bernd. “Not only because it is great to collaborate with colleagues from other departments, but also because it is super educational.” 2. System integration tests in a CI/CD pipeline “We want to demonstrate that we can perform click tests in the frontend in an existing environment and verify whether everything works together properly,” says Stef Noten. “We can currently run the necessary tests locally, so we are good on schedule. The next step is to also make this work in our build pipeline. At the end of the day, we hope we will be able to run the tests either manually or scheduled on the latest version of the backend and frontend .” 3. Onboarding portal/platform including gamification The members of this project team all started at ACA fairly recently. And that is exactly what brought them together, because their goal was to develop a platform that makes the onboarding process for new employees more efficient and fun . Dieter Vennekens shared his enthusiasm with us, stating, "We kicked off with a brainstorming session to define the platform's requirements and goals. Subsequently, we reviewed these with the key users to ensure the final product aligns with their expectations. Our aim is to establish the basic structure before lunch, allowing us to focus on development and styling intensively in the afternoon. By the day's end, our objective is to unveil a functional prototype. This project serves as an opportunity to showcase the capabilities of Low-Code .” 4. Automatic dubbing, transcription and summary of conversations Upon entering their meeting room, we found the project team engrossed in their work, and Katrien Gistelinck provided a concise explanation for their business. "Our project is essentially divided into two aspects. Firstly, we aim to develop an automatic transcription and summary of a conversation . Concurrently, we are working on the live dubbing of a conversation, although we're uncertain about the feasibility of the latter within the day. It might be a tad ambitious, but we are determined to give it a try." She continued, "This morning, our focus was on defining the user flow and selecting the tools we'll utilize. Currently, multiple tasks are progressing simultaneously, addressing both the UI and backend components." 5. Publiq film offering data import via ML Comprising six publiq employees and three from ACA, this team engaged in an introductory round followed by a discussion of the project approach at the whiteboard. They then allocated tasks among themselves. Peter Jans mentioned, "Everyone is diligently working on their assigned tasks, and we maintain continuous communication. The atmosphere is positive, and we even took a group photo! Collaborating with the customer on a solution to a specific challenge for an entire day is energizing. " "At the close of the day, our objective is to present a functional demo showcasing the AI and ML (Machine Learning) processing of an email attachment, followed by the upload of the data to the UIT database. The outcome should be accessible on uitinvlaanderen.be ." Peter adds optimistically, "We're aiming for the win." That's the spirit, Peter! 6. SMOCS, Low level mock management system Upon our arrival, the SMOCS team was deeply engrossed in their discussions, making us hesitant to interrupt. Eventually, they graciously took the time to address our questions, and the atmosphere was undoubtedly positive. "We initiated the process with a brief brainstorming session at the whiteboard. After establishing our priorities, we allocated tasks accordingly. Currently, we are on track with our schedule: the design phase is largely completed, and substantial progress has been made with the API. We conduct a status check every hour, making adjustments as needed," they shared. "By the end of the day, our aim is to showcase an initial version of SMOCS , complete with a dashboard offering a comprehensive overview of the sent requests along with associated responses that we can adjust. Additionally, we have high hopes that the customized response will also show up in the end-user application." 7. Composable data processing architecture This project team aims to establish a basic architecture applicable to similar projects often centered around data collection and processing. Currently, customers typically start projects from scratch, while many building blocks could be reused via platform engineering and composable data. “Although time flies very quickly, we have already collected a lot of good ideas,” says Christopher Scheerlinck. “What do we want to present later? A very complex scheme that no one understands (laughs). No, we aspire to showcase our concepts for realizing a reusable architecture , which we can later pitch to the customer. Given that we can't provide a demo akin to other teams, we've already come to terms with the likelihood of securing second place!" 8. Virtual employees This team may have been the smallest of them all, but a lot of work had already been done just before noon. “This morning we first had a short meeting with the customer to discuss their expectations,” Remco Goyvaerts explains. “We then identified the priority tasks and both of us quickly got to work. The goal is to develop a virtual colleague who can be fed with new information based on AI and ML . This virtual colleague can help new employees find certain information without having to disturb other employees. I am sure that we will be able to show something beautiful, so at the moment the stress is well under control.” Chatbot technology is becoming more and more popular. Remco sees this Ship-IT project as the ideal opportunity to learn more about applications with long-term memory. “The Ship-It Day is a fantastic initiative,” says Remco. “It's wonderful to have the opportunity to break away from the routine work structure and explore innovative ideas.” 9. Automated invoicing The client involved in this project handles 50,000 invoices annually in various languages. The objective is to extract accurate information from these invoices, translate it into the appropriate language, and convert it into a format easily manageable for the customer . “Although we started quite late, we have already made great progress,” notes Bram Meerten. "We can already send the invoice to Azure, which extracts the necessary data reasonably well. Subsequently, we transmit that data to ChatGPT, yielding great results. Our focus now is on visualizing it in a frontend. The next phase involves implementing additional checks and solutions for line information that isn't processed correctly." Bram expresses enthusiasm for the Ship-IT Day concept, stating, "It's fun to start from scratch in the morning and present a functional solution at the end of the day. While it may not be finished to perfection, it will certainly be a nice prototype." And the winner is …. 🏆 At 5 p.m., the moment had arrived... Each team had the opportunity to showcase their accomplishments in a 5-minute pitch, followed by a voting session where everyone present could choose their favorite. All teams successfully presented a functional prototype addressing their customer's challenges. While the SMOCS team may not have managed to visualize their solution, they introduced additional business ideas with the SMOCintosh and the SMOCS-to-go food concept. However, these ideas fell just short of securing victory. In a thrilling final showdown, the team working on the onboarding platform for ACA came out as the winners! Under the name NACA (New at ACA), they presented an impressive prototype of the onboarding platform, where employees gradually build a rocket while progressing through their onboarding journey. Not only was the functionality noteworthy, but the user interface also received high praise. Congratulations to the well-deserving winners! Enjoy your shopping and dinner vouchers. 🤩 See you next year!

Y ou can’t design or develop something for all 7.9 billion people on the planet. So when we start a project, we decide on a target audience to narrow it down. From there we build our features and designs in a way that seems fitting for that audience. However, what we can’t narrow down on are the accessibility features. Everybody needs to have the possibility to use or experience your said creation. Some devices have built-in features like Google Talkback , where your device can tell you what’s happening on screen and even use that information with a digital braille reader. Or sometimes we make sure our platforms are accessible to use, such as our website, which by the way has a Google Lighthouse accessibility score of 98! But why stop there? Every piece of content should be accessible for everyone. This also counts for PDF files. Get started with these 3 tips we’ve gathered using a MediMarket Case Study : Do an accessibility check with Acrobat Pro First things first: do an accessibility check with Adobe Acrobat Pro. This check immediately indicates in a clear list which issues you need to face. Some of these issues can be solved directly in Acrobat Pro, and others require you to go back to your source file or check manually. You can gather a bit more knowledge by clicking the Autotag Document option. This will read the PDF and give you another accessibility summary about missing alt text, but more about this later. Realize the importance of the reading order Ever heard a screen reader freak out because it doesn’t understand your reading order or structure in the PDF file? Well, imagine someone talking way too fast, without stopping and without any clue what they want to say. Sounds chaotic, right? Now think about the users that really depend on these types of digital aids. Your PDF is basically useless when this happens. So be certain you have a structured document with the right identity headings, paragraphs and sections when creating the PDF. Want to add this to an existing PDF? With Acrobat Pro, you can read the reading order later thanks to their accessibility options. In this screenshot you can clearly see what the screen reader will read first, second, third and so on. Did you know Alt Text is also possible in PDF files? Is this the surprise of the day, or did you never bother to add an alternative text in your documents? Well, start by adding alt text on images or interactive fields. A screen reader can’t read your JPEG files and you need to explain what is shown to them. Don’t overdo it though, your user doesn’t really need to know you added that cute cat photo as filler. Don’t do this just with images. Audio and video elements are also in need of alt text. This isn’t only necessary for users with bad eyesight or hearing, but also for users with bad internet connection who only can download the text of your PDF. There is a lot more to this, but these 3 tips can certainly get you started! However, what I really wanted to achieve with this blogpost is that you start thinking about making all your content more accessible. Do you want more information about accessibility, for example in mobile applications? Go to our services and see for yourself what we can help you with!
