other useful things.

## Usage

```go

    docs := []string{

        "Samsung Galaxy Tab A 10.5 review: Slate will impress multimedia enthusiasts",

        "Why banks are upgrading your debit, credit cards",

    }

    ts := textsimilarity.New(docs)

    docA := "Gold prices edge up as easing trade concerns hurt dollar"

    docB := "Global gold prices edge up as easing trade concerns hurt dollar"

    result, _ := ts.Similarity(docA, docB)

    keywords := ts.Keywords(0.2, 0.5)

    fmt.Println(result)

    fmt.Println(keywords)
