The Eighth BCS-IRSG Symposium on Future Directions in Information Access (FDIA 2018) Ingo Frommholtz, Haiming Liu, Ingo Schmitt, Dawei Song

Call for WorkShop Papers/FDIA

Our 2018 PhD Symposium on Future Directions in Information Access (FDIA) will be held in conjunction with the 8th International Conference on the Theory of Information Retrieval (ICTIR 2018, on 14th September 2018, in Tianjin, China. We cordially invite masters and doctoral students to submit a short 2-4 page paper on their research topic to the symposium. You will learn different topics of Information Access/Retrieval and get great feedback on your topic, meet lots of other students, as well as hear inspiring talks. The Symposium provides an excellent opportunity for students to provide pointers to their work and obtain experience in presenting and communicating their research. We especially encourage submissions on formative research ideas which present a summary of their doctoral work, initial empirical findings/pilot studies, explore conceptual and/or theoretical models, and/or describe current challenges and opportunities. Submissions focusing on new directions and emerging work in Information Access/Retrieval which create discussion and provoke reaction are strongly encouraged. Note the work need not be original and can be a summary of past and current work.

Areas of research include, but are not limited to:

  • Information Retrieval Theory
  • Human Computer Interaction and Information Retrieval, Interactive IR
  • Collaborative Information Seeking and Searching
  • Learning to Rank
  • Multimedia and Multimodal IR
  • Recommender Systems
  • Databases + IR
  • Semantic Search
  • Social Search
  • Web IR
  • Clustering and Categorization
  • Enterprise Search
  • Conversational Agents, knowledge graphs
  • IR Applications (e.g. Digital Humanities, E-Learning, etc.)

  • Submission Details

    All papers will be peer reviewed by at least one senior researcher on the Programme Committee. Papers should be 2-4 pages in length for presentation and poster (e.g., an outline of the PhD or Master’s project), and 1-2 pages for poster only (e.g., a summary of research direction).

    All submissions should be submitted in Electronic Workshops in Computing (eWiC) Format using the Word or Latex templates (see

    Submissions should be converted to PDF and submitted via Easy Chair:

    We strongly encourage students to submit as a solo author papers. A selection of papers will be invited to give a short oral presentation, while all participants will be asked to present a poster.

    > Passport and Visa

    Passports, valid for at least 3 months from the entry into China, and entry visas are required to visit China. Participants are advised to consult the nearest Chinese diplomatic mission for details. A single entry visa is valid for three months, and can be extended for an additional month at the Foreigners Section of the Local Public Security Bureau if necessary. Once in China, the participants are advised to carry their passports on them at all times because the passports may be needed to check into hotels, book airline tickets, and change money. Participants from Japan, Singapore within 15 days do not need to apply visa to entry China. For most attendees, it is easier to apply for a Tourist ("L") visa; an invitation letter is NOT required for obtaining a Tourist visa. If some participants need type ("F") of visa that does require an invitation letter, the ICTIR2018 local arrangement committee will be glad to help. To apply for visas, participants should first fill out the registration form with the appropriate registration fee. The Conference Secretariat will then send a formal invitation form via email or fax with which the participants can apply for a visa at the Chinese diplomatic mission indicated in the invitation. This application should be made preferably at least one month before departure for China. Alternatively, participants may ask their travel agents to arrange their travel to China and obtain a tourist visa irrespective of whether or not they have registered with the Conference Secretariat. If participants have any difficulties in obtaining their visa, they should contact the Conference Secretariat.

    Student Travel Grants

    The ACM SIGIR Student Travel Grants Program offers financial supports to eligible student authors of accepted ICTIR2018 papers. For a student to be eligible, he or she must meet one of two criteria:

    • (1) be an author of a short or full paper and
    • (2) be the one presenting the work at the conference.

    The application process involves two steps:

    • (1) the student must submit an application, which requires the student to explain what they wish to gain from attending ICTIR 2018, and
    • (2) independently, the academic advisor will be required to submit a statement of support.

    Both application forms will be available here ( The application period is June 29 to July 16, 2018. Both student and academic advisor forms must be submitted before the end of the application period.
