Stable, scalable, and has testing and conversational AI features

The total time it takes to deploy IBM Watson Discovery depends on the documents you'll be working with. For example, I was in a situation where I was working with some painting files and folders for a painting store. The store had PDF documents, but the information was mixed up, so I had to treat the documents on IBM Watson Discovery, and discovering and understanding each PDF file took longer. The process is more straightforward for plain documents, and you have to work with questions that will help IBM Watson Discovery understand the documents. The time to deploy the product depends on the quantity and type of documents you'll be working with.

Frequent updates, highly stable, and robust

We have had thousands of users, the solution is highly scalable. We have had a large installation of OpenText Decisiv and there were approximately 6,000 users. The user's roles vary, such as records managers. Additionally, depending on the organization, a lot of our clients are in the federal government which they have different types of roles, but most of them are end-users. They're searching for documents or the records that are in their repository, there are document producers, but most people are searching.

Quotes from Members

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

Pros

"Being able to have some rules to extract the entities is valuable. The capability to crawl external sites and internal documents, and then draw internal information with external contents is also valuable."

"The most valuable feature of IBM Watson Discovery is testing, mainly because the product applies conversational AI, which means I can ask questions to get the information I want from a specific test area."

"Being able to have some rules to extract the entities is valuable."

"Language support and the ability to build a natural language of speech recognition are the most valuable features."

"It has allowed us to provide longer service availability for support to users."

"The most valuable features of IBM Watson Discovery are the integration with the rest of the Watson Suite and the Watson Assistant capability. If you use Watson Assistant, the ability for it to be able to determine the accuracy of your voice models and your voice response systems is a benefit."

"If I was going to rank all the ECM solutions, OpenText Decisiv is the best because I have used the other ones and even though it's not the easiest to use at times, it is the most powerful, robust software out there."

"The most valuable feature of OpenText Decisiv is they are always improving."

Cons

"IBM Watson Discovery has moved to a newer version and it is very difficult to train the newer version."

"The support from IBM Watson Discovery is good but could improve to make it great."

"It needs a lot of memory. Our index is very big. It is around 100 gigabytes. So, we need more than 100 gigabytes of memory to use Watson."

"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this. Having said that, Watson is way more flexible. While it may require a greater amount of effort, it is not substantially more than some of the other ones that are kind of prebuilt for a specific use case. It would be good to have more prebuilt and specific use cases and specific business models. It can have better phone integration, even though I think that it is actually becoming less of an issue. Most people are online nowadays."

"The pricing is an area for improvement in IBM Watson Discovery because the customer initially used the free version. Still, when he needed more questions and documents, he had to move to a different version, which was paid and cost $500 per month. That change in pricing made my company lose many customers."

"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this."

"OpenText Decisiv is difficult to do customization. They need to improve this."

Pricing and Cost Advice

"Cost-wise, it is very reasonable because it is cloud-based."

"IBM Watson Discovery is an expensive product."

"The price of the solution can vary drastically because it depends on the modules that a client using. There is an additional cost of approximately 25% for maintenance."
