I have a paragraph that starts with the following

In order to obtain a more accurate result, additional knowledge is required.

My next line is as follows but it doesn't feel right...

One such type of knowledge can be that the problem is to find anomalies with different parameters from those of the surrounding material.

I came up with an alternate sentence, does this seem better or worse?

One example of such knowledge is a problem that involves finding anomalies with different parameters from those of the surrounding material.

The second one is definitely better but it's still a bit incorrect because a problem cannot be an example of "knowledge". Knowledge can help you solve a problem but the problem itself is not knowledge. Generally your use of "knowledge" is a bit strange because "knowledge" is a very general term, perhaps equivalent to "the sum total of everything that you know". It's not used very often in this sort of context because it's very vague.

To describe the state of having a lot of knowledge about a specific area or subject, it would be better to use the word "expertise", or perhaps "experience" or "ability", and you should be careful to distinguish this from information, which someone might also need to solve the problem, regardless of how much experience they have.

It's not clear, in the first sentence, whether you mean expertise or information, but from the context of the second sentence it looks like you mean expertise/experience.

Perhaps you could say:

In order to obtain a more accurate result, additional problem-solving ability is required. One example of this would be the ability to solve a problem that involves finding anomalies with different parameters from those of the surrounding material.

EDIT: if you're talking about information, you could say

In order to obtain a more accurate result, additional information is required. This information could, for example, allow us to solve a problem that involves finding anomalies with different parameters from those of the surrounding material.

  • Thanks for your answer. I think 'information' is what I was trying to get across rather than 'knowledge'. It's about having additional information about a physical situation. – eurocoder Mar 1 '16 at 9:45
  • You could think about "data" as well then. Data is what you gather, information is data that has been processed to be more meaningful. – Max Williams Mar 1 '16 at 10:08
