It can be difficult to figure by hand which properties are most likely cover the same concepts (based on the property label) [0] therefore Special:PropertyLabelSimilarity will help with that effort by calculating the syntactic similarity and provide a list such as:

The page only reports those similarities and does not provide a function for merging or deleting reported properties, instead the user should use the information to create redirects [1] or delete duplicate properties.

Of course, sometimes the syntactic similar of a property may in fact be a false positive on the assumption that both represent the same concept and to eliminate those cases smwgSimilarityLookupExemptionProperty setting contains the name (which by default is owl:differentFrom) of a property that is used to mark and exempt properties from each by declaring them to be different from each other.

Furthermore, to give the report a bit more flexibility, the threshold of the similarity distance can be freely adjusted.

The Type ID checkbox is to help making a quick assumption about the nature of a property and as it can be seen on [0] because sometimes results reveal similar names but different types.

    {
        "property": [
            {
                "label": "Defaultvalue1",
                "type": "_txt"
            },
            {
                "label": "Defaultvalue4",
                "type": "_dat"
            }
        ],
        "similarity": 92.31
    },

What's more, the user has to select a limit to minimize the computational effort (the comparison is exponential with size of the list members).
