A data analysis tool that is scalable and includes keyword search functionality
The solution is used for a government company for data collection and analysis I have found the auto-generated document very useful as well as the main keywords that are highlighted, which are used for the search functionality within IBM Watson Explorer. I have been using the solution for five…

Enables fast project development with efficient workflow modifications and promising features while offering modularity and reusability
KNIME is simple and allows for fast project development due to its reusability. I appreciate the ability to make improvements or modifications in existing workflows. Although I have not yet used the forecasting and customer profiling features, I find them promising. Another effective feature is the ability to use GET request objects to retrieve data from websites or APIs. This makes iterative steps easy to manage. It is more elastic and modern compared to SAP Data Services, allowing node creation and regrouping components or steps for reuse in different projects.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"IBM has been working with Bradesco since 1968, I think, and the support is very good, with a team of 10 IBM employees working every day, 24 hours, inside the bank in Sao Paolo."
"We take natural language that was happening in our repositories and our application and then feed it to the Watson APIs. We receive JSON payloads as an API response to get cognitive feedback from the repository data."
"What impressed me more about Watson is that it is easy to use it, not for the technical people, but for business people."
"The valuable feature of Watson Explorer for us is data entities, and being able to see hidden insights from within unstructured data."
"The ability to easily pull together lots of different pieces of information and drill down in a smarter way than has been possible with other analytics tools is key. Watson is all based on a set of AI and deep learning, machine-learning capabilities, and it is looking behind the scenes at some relationships that you likely would not have spotted on your own. It's pulling things together, categorizing some things, that are not something that you might have seen on your own."
"The ability to easily pull together lots of different pieces of information and drill down in a smarter way than has been possible with other analytics tools is key."
"I really can't talk enough about the team."
"Previously we'd have a set of health and safety analysts who would be the key focal points for doing work to understand health and safety risks; so a very small number of people, but through WEX and through our Watson HSEQ solution, we've managed to get engagement across at least one-third of our workforce, so over 1,300 people, and a 25% reduction in health and safety incidents."
"It has an excellent interface, is very easy to use, really boosts productivity, has impressive performance even on a normal laptop, and its diversity of tools for preprocessing and integration with R and Weka make it the perfect data mining solution."
"It is a stable solution...It is a scalable solution."
"It's a very powerful and simple tool to use."
"We have been able to appreciate the considerable reduction in prototyping time."
"The most valuable feature is the data wrangling, which is what I mainly use it for."
"There are a lot of connectors available in KNIME."
"The hardest part is keeping a tidy workspace because of the many nodes involved. When teaching, it would be helpful if there was more emphasis on how to group nodes effectively. For example, turning frequently used nodes into a single component can simplify things."
"This solution is easy to use and especially good at data preparation and wrapping."
 

Cons

"Much of IBM operates this way, where they have sets of tools that are in the middleware space, and it becomes the customer's responsibility or the business partner's responsibility to develop full solutions that take advantage of that middleware."
"The solution is expensive."
"No, it's not yet stable."
"I think we'll get it to a 10, but I think at the moment it's got to be a good eight or nine out of 10 at least."
"It needs better language support, to include some other languages. Also, they should improve the user interface."
"More cognitive feedback would be good. The natural language analysis is great, the sentiment analyzers are great, but I would just like to see more innovation done with the Watson platform."
"It needs better language support, to include some other languages. Also, they should improve the user interface."
"Stability is actually one of the areas that could use improvement. Setting it up is always tough; setting Explorer requires experts, and the underlying platform is not that stable, so it really needs a good expert to keep it running."
"Scalability is limited to a desktop application."
"KNIME is not good at visualization."
"Both RapidMiner and KNIME should be made easier to use in the field of deep learning."
"The license is quite expensive for us."
"The current UI is primarily in English. Analyzing data in local languages might present challenges or issues."
"The most difficult part of the solution revolves around its areas concerning machine learning and deep learning."
"They could add more detailed examples of the functionality of every node, how it works and how we can use it, to make things easier at the beginning."
"From the point of view of the interface, they can do a little bit better."
 

Pricing and Cost Advice

"The solution is expensive."
"KNIME is free as a stand-alone desktop-based platform but if you want to get a KNIME server then you can find the cost on their website."
"While there are certain limitations in functionality, you can still utilize it efficiently free of charge."
"There is a Community Edition and paid versions available."
"KNIME is an open-source tool, so it's free to use."
"The client versions are mostly free, and we pay only for the KNIME server version. It's not a cheap solution."
"KNIME is a cheap product. I currently use KNIME's open-source version."
"KNIME is a cost-effective solution because it’s free of cost."
"They have different versions, but I am using the open-source one."
