 ## Relationships
 
 ### ASSOCIATED_WITH (Channel → Topic)
 
-- **channel_score**: Cumulative or weighted score representing a topic’s importance or relevance to the channel
-- **keywords_weights**: Channel-specific keywords and their weights, reflecting the unique relationship between the
-  channel and topic
+- **topic_score**: Cumulative or weighted score representing a topic’s importance or relevance to the channel
+- **keywords_weights**: Channel-specific keywords and their weights, highlighting the unique relationship between the channel and topic
 - **message_count**: Number of messages analyzed in relation to the topic
 - **last_updated**: Timestamp of the last update
-- **score_decay_rate**: Rate at which `channel_score` decreases over time if no new relevant messages are analyzed. This
-  decay rate allows topic scores to adjust gradually, so less active or outdated topics diminish in relevance without
-  active content.
 - **trend**: Indicator of topic trend over time within the channel
 
-> **Explanation**: `score_decay_rate` ensures that topics associated with a channel decrease in relevance if no new
-> messages support their ongoing importance. This helps maintain an accurate and current reflection of active discussions
-> in a channel, giving more weight to trending or frequently discussed topics while allowing older or less relevant topics
-> to fade naturally.
+> **Explanation**: This relationship captures the importance of each topic to specific channels, with channel-specific keyword weights providing additional insight into unique topic-channel dynamics. `trend` enables tracking how each topic's relevance changes over time within the channel.

 ### RELATED_TO (Topic ↔ Topic)
 
 - **similarity_score**: Degree of similarity between two topics
-- **temporal_similarity**: Time-based similarity metric to track changing topic relationships over time
-- **co-occurrence_rate**: Frequency with which two topics are discussed together across channels
+- **temporal_similarity**: Metric to track similarity over time
+- **co-occurrence_rate**: Frequency of concurrent discussion of topics across channels
 - **common_channels**: Number of shared channels discussing both topics
-- **topic_trend_similarity**: Similarity in trends or changes in relevance for each topic
