What’s the best way to interpret Likert Scales with equal negative and positive Likert Items?

What's the best way to interpret Likert Scales with equal negative and positive Likert Items that represent each construct presented?

Construct: Accuracy of Data
Scale: Agree-Disagree (1 to 5)

• The data is accurate? (positive) Responses: 5(Dan),5(James),4(Sarah)
• The data is not accurate? (negative) Responses: 1(Dan),1(James),2(Sarah)

I know that bar graphs can be used to illustrate how respondents felt about each Likert Item individually (e.g. 45% strongly agreed that the data is accurate), but assuming that the split half reliability method shows that the data I have collected can be trusted from face value, how could I best group the information by like-minded constructs (e.g. Data being the construct in the two questions above)?
