SIGIR 2014 Workshops

SIGIR'14 will host seven attractive workshops covering novel ideas and emerging areas in IR.

Please look at the individual websites for the calls, and deadlines — and participate in the discussion on the SIGIR'14 workshop day, on Friday 11 July 2014, in the beautiful scenery of Gold Coast, Queensland, Australia.

ERD'14: Entity Recognition and Disambiguation Challenge

The Entity Recognition and Disambiguation Workshop will be organized as a challenge, where participants submit working systems that identify the entities mentioned in text. The challenge will have two tracks, focusing on long and short texts. All submissions will be evaluated on shared datasets; part of the data will be withheld, to be used for the final evaluation of all submitted systems to determine the winners. Each participating team will be offered a spot at the workshop to present their system.

PIR'14: Privacy-Preserving IR: When Information Retrieval Meets Privacy and Security

Information retrieval and information privacy/security are two fast-growing computer science disciplines. There are many synergies and connections between these two disciplines. However, there have been very limited efforts to connect the two. On the other hand, due to lack of mature techniques in privacy-preserving IR, concerns about privacy and security have become serious obstacles that prevent valuable user data to be used in IR research such as studies about query logs, social media, tweets, sessions, and medical record retrieval. This privacy-preserving IR workshop aims to spurring research brings together the research fields of IR and privacy/security, and mitigate privacy threats in information retrieval by exploring novel algorithms and tools.

SMIR'14: Semantic Matching in Information Retrieval

Recently, significant progress has been made in research on what we call semantic matching (SM), in Web search, question answering, online advertisement, cross language information retrieval, multimedia retrieval, and other tasks. Let us take Web search as example of the problem. When comparing the textual content of query and documents, the simple term-based approaches can fail when searcher and author use different terms. A more realistic approach beyond bag-of-words, referred to as semantic matching (SM), is to conduct deeper query and document analysis to encode text with richer representations and then perform query-document matching with such representations. The main purpose of the workshop is to bring together IR and NLP researchers working on or interested in semantic matching, to share latest research results, express opinions on the related issues, and discuss future directions.

TAIA'14: Temporal, social and spatially Aware Information Access

Users provide an unprecedented volume of detailed, and continuously updated information about where they are, what they are doing, who they are with, and what they are thinking and feeling about their activities. The provision of this stream creates an informal contract between the user and the information access application in which the user will provide the information, but the application must provide results that are contextually relevant. In this workshop we explore spatial and temporal context in dynamic geotagged collections, such as Wikipedia, and traditional news sources, as well as social media sites such as Twitter, Foursquare, Facebook and Flickr. To ground the workshop, and provide a locus for discussion of the two aspects of user context, we focus on event detection and recommendation. Events are a natural theme around which to center discussions of spatial and temporal context because events are defined by their time and place.
