+MANY entities and relationships were missed in the last extraction. Please find only the missing entities and relationships from previous text. Do not include entities and relations that have been previously extracted. :\n
 
 ---Remember Steps---
-
-1. Identify all entities. For each identified entity, extract the following information:
+1. Recognizing definitively conceptualized entities in text. For each identified entity, extract the following information:
 - entity_name: Name of the entity, use same language as input text. If English, capitalized the name
-- entity_type: One of the following types: [{entity_types}]
-- entity_description: Provide a comprehensive description of the entity's attributes and activities *based solely on the information present in the input text*. **Do not infer or hallucinate information not explicitly stated.** If the text provides insufficient information to create a comprehensive description, state "Description not available in text."
-Format each entity as ("entity"{tuple_delimiter}<entity_name>{tuple_delimiter}<entity_type>{tuple_delimiter}<entity_description>)
+- entity_type: One of the following types: [{entity_types}]. If the entity doesn't clearly fit any category, classify it as "Other".
+- entity_description: Provide a comprehensive description of the entity's attributes and activities based on the information present in the input text. Do not add external knowledge.
 
-2. From the entities identified in step 1, identify all pairs of (source_entity, target_entity) that are *clearly related* to each other.
+2. Format each entity as:
+("entity"{tuple_delimiter}<entity_name>{tuple_delimiter}<entity_type>{tuple_delimiter}<entity_description>)
+
+3. From the entities identified in step 1, identify all pairs of (source_entity, target_entity) that are directly and clearly related based on the text. Unsubstantiated relationships must be excluded from the output.
 For each pair of related entities, extract the following information:
 - source_entity: name of the source entity, as identified in step 1
 - target_entity: name of the target entity, as identified in step 1
-- relationship_description: explanation as to why you think the source entity and the target entity are related to each other
-- relationship_strength: a numeric score indicating strength of the relationship between the source entity and target entity
 - relationship_keywords: one or more high-level key words that summarize the overarching nature of the relationship, focusing on concepts or themes rather than specific details
-Format each relationship as ("relationship"{tuple_delimiter}<source_entity>{tuple_delimiter}<target_entity>{tuple_delimiter}<relationship_description>{tuple_delimiter}<relationship_keywords>{tuple_delimiter}<relationship_strength>)
+- relationship_description: Explain the nature of the relationship between the source and target entities, providing a clear rationale for their connection
 
-3. Identify high-level key words that summarize the main concepts, themes, or topics of the entire text. These should capture the overarching ideas present in the document.
-Format the content-level key words as ("content_keywords"{tuple_delimiter}<high_level_keywords>)
+4. Format each relationship as:
+("relationship"{tuple_delimiter}<source_entity>{tuple_delimiter}<target_entity>{tuple_delimiter}<relationship_keywords>{tuple_delimiter}<relationship_description>)
 
-4. Return output in {language} as a single list of all the entities and relationships identified in steps 1 and 2. Use **{record_delimiter}** as the list delimiter.
+5. Use `{tuple_delimiter}` as feild delimiter, and use `{record_delimiter}` as the list delimiter.
 
-5. When finished, output {completion_delimiter}
+6. When finished, output `{completion_delimiter}`
+
+7. Return identified entities and relationships in {language}.
