 To filter content within a specific category, or filter specific types of content :
 
 *   **Categories:** Filter by `category="news"`, `category="music"`, or `category="video"` to prioritize content.
+*   **Language:** Filter by `lang="fr"` to show language relevant categories.
 *   **Context-Aware Filtering:** Combine scores with keywords, tags, or user settings to match the current context.
 *   **Algorithme :** The formula `trust(B)=math.sqrt(trust(A,B)×trust(User,A))` can be changed to only take into account direct friends, or if they are tagged using a specific keyword.
 *   **UX:**  Show the user the category of content being filtered, and give them easy controls on how to tweak it.
