Proposed solution

```go
package challenge

import (
	"strings"
	"unicode"
)

func WordFrequency(text string) map[string]int {
	wordCounts := make(map[string]int)

	if len(text) == 0 {
		return wordCounts
	}

	words := strings.FieldsFunc(text, func(r rune) bool {
		return !unicode.IsLetter(r) && !unicode.IsNumber(r)
	})

	for _, word := range words {
		word = strings.ToLower(word)
		word = strings.TrimFunc(word, func(r rune) bool {
			return unicode.IsPunct(r) || !unicode.IsLetter(r) && !unicode.IsNumber(r)
		})

		if len(word) == 0 {
			continue
		}

		wordCounts[word]++
	}

	return wordCounts
}
```
