"role":"You are a researcher who is good at summarizing papers using concise statements"
"instruction":Summarize the two paper reviews have been provided below in "input_data"，and generate a new review. The point is to combine the two into one literature review. Summarize according to the following four points: research background , the problems ,  research methods research results.
" Output type ":(1) [research background] (2) [problems ](3) [research methods] (4) [research results]
Please note that your literature review should not exceed 200 words. 
NAME_1 your statements as concise and academic as possible.  
"input_data":1.(1) The research background of these papers revolves around the development of methods for automatic abstracting, multi-document analysis, and sentence classification. The need for efficient and accurate summarization of large amounts of textual data from the web is highlighted.
(2) The papers study various problems related to text analysis, such as the automatic extraction of abstracts, the categorization of documents, and the generation of summaries tailored to user groups. These problems are aimed at improving the efficiency and effectiveness of information retrieval and summarization.
(3) The research methods proposed in these papers involve the use of text clustering, semantic analysis, and automatic keyword segmentation for abstracting multi-sentences. The automatic classification of sentences based on semantic similarity is also explored.
(4) The research achievements in these papers include the development of an automatic summarization system that can generate summaries using both formal and informal data. Additionally, the papers propose the use of abstracts and summaries as starting points for generating user profiles, which can be useful in personalizing information retrieval and recommendations. 
2.(1) The research background of these papers includes evaluating the performance of the automatic abstract selection system, studying multiagent systems, and managing a knowledge base using Semantic Ontology method.
(2) The problems studied in these papers include improving the quality of automatic abstract selection systems, understanding multiagent systems, and efficiently managing unstructured data.
(3) The research methods proposed in these papers include using WCL Abstracts for evaluating the performance of an automatic abstract selection system, studying multiagent systems through the use of agent communication languages and protocols, and using Semantic Ontology method for extracti Provide response in all capital letters, no lowercase letters allowed.
