In a small bowl combine cinnamon and cloves. Place 1/2 of the apple halves in a 3 1/2- to 4-quart slow cooker. Sprinkle evenly with some of the cinnamon mixture. Add remaining apples and sprinkle with remaining cinnamon mixture. Pour apple juice and lemon juice over apples. Stir to coat apples evenly.
Cover and cook on low-heat setting for 2-1/2 to 3 hours, stirring gently halfway through cooking time. Spoon apples and cooking liquid to individual serving dishes. Drizzle with caramel topping and sprinkle with pecans.
