SIGIR is the major international forum for the presentation of new research results and for the demonstration of new systems and techniques in the broad field of information retrieval (IR). The Conference and Program Chairs invite all those working in areas related to IR to submit original full papers, short papers, and proposals for tutorials, workshops, and demonstrations of systems. SIGIR 2013 welcomes contributions related to any aspect of IR theory and foundation, techniques, and applications. Relevant topics include, but are not limited to:

• 
  
• Document Representation and Content Analysis (e.g., text representation, document structure, linguistic analysis, multi-lingual IR, cross-lingual IR, NLP for IR, information extraction, sentiment analysis, clustering, classification, topic models, facets, text streams)
  
• Queries and Query Analysis (e.g., query representation, query suggestion, query reformulation, query intent, conversational search, query log analysis, session analysis, question answering)
  
• Users and Interactive IR (e.g., user models, user studies, user feedback, search interface, summarization, task models, personalized search)
  
• Retrieval Models and Ranking (e.g., IR theory, language models, probabilistic retrieval models, feature-based models, learning to rank, combining searches, diversity)
  
• Search Engine Architectures and Scalability ( e.g., indexing, compression, distributed IR, P2P IR, mobile devices)
  
• Filtering and Recommending (e.g., content-based filtering, collaborative filtering, recommender systems, profiles)
  
• Evaluation (e.g., test collections, effectiveness measures, experimental design)
  
• Web IR and Social Media Search (e.g., link analysis, click models/behavioural modelling, social tagging, social network analysis, advertising and search, blog search, microblog search, forum search, community-based QA (CQA), adversarial IR, vertical and local search)
  
• IR and Structured Data (e.g., XML search, ranking in databases, desktop search, entity search)
  
• Multimedia IR (e.g., image search, video search, speech/audio search, music IR)
  
• Other Applications (e.g., digital libraries, enterprise search, genomics IR, legal IR, patent search, text reuse)
