Editorial Charter

The ACM Transactions on Information Systems (TOIS) considers the design, performance, and evaluation of computer systems that facilitate information access in a variety of media, as well as underlying technologies that support these systems. The major themes of TOIS and those topics which distinguish it from other ACM Transactions include:

• Information Retrieval and Information Filtering: Algorithms and inference mechanisms for search, retrieval, and presentation of information with emphasis on semi-structured and unstructured objects in large-scale environments such as private distributed enterprises and the WWW.
• Distributed Information Retrieval: Federated search, WebIR, peer-to-peer techniques.
• Information Interaction Interfaces: Search and exploration interfaces, information visualization, multimedia presentation, task and user models for information access.
• Models of User Information Preferences and Interaction Behaviors.
• Language Technologies: Including summarization and natural language processing with application to information access.
• Knowledge and Information Representation: Representation issues for supporting information systems including document markup to facilitate retrieval and understanding; topic and entity detection; ontologies and metadata schemes to support classification, retrieval, extraction, and preservation.
• Algorithms, Data Structures, Methods, and Processes for Facilitating Information Access.
• Knowledge Discovery: With emphasis on text and multimedia data mining, recommender system algorithms, and interaction models.
• Multimedia Information Systems: With emphasis on retrieval and user interactions.
• Organizational Interfaces for Information Access and Social Impact of Information Systems: adversarial computing and information access; social networks the effects of information access systems on groups, organizations, and communities; social constraints imposed on information systems such as legal and privacy concerns.
• Design and Evaluation of Information Access Systems: Design principles for information systems, including long-term storage, versioning, and preservation; methodologies for evaluating information systems.
• Information System Applications: Digital libraries; genomic databases; digital publishing; geographic information systems; and tutoring systems.
