  • Ms. Watraut Ritter (Knowlede Dialogues), guest lecture: "Data Governance in Cities: Who owns urban data?"

Abstract: In recent years cities around the world developed new approaches to manage urban data; “urban informatics” and “smart city” are concepts where information, data, and technology become the basis for new models of managing processes in a city.  How is the urban information space governed? How can we address questions about usage, ownership and access to human and machine-generated data?

Currently, many smart city approaches see governance only within the framework of public-private partnerships between city administrators and ICT service providers, while few cities develop more inclusive multi-stakeholder frameworks of governance.

Using examples from cities in Europe and Asia,  the presentation describes and discusses recent developments and potential of leveraging data and information for participatory urban planning and design to efficiently use a city's resources and increase the quality of live for all citizens.

This comparative study across different cities is an ongoing research project, and aims to contribute to the emerging topic of urban data governance from an information science perspective.

Short Bio: Waltraut Ritter is principal at Knowledge Dialogues, specializing in applied research  on innovation and knowledge economy in the Asia Pacific Region and works for government agencies, public and private research institutes and international organisations. In recent years, she has conducted a number of projects related to knowledge/smart cities. She serves on the Digital Strategy Advisory Committee of the Hong Kong government.

She has a M.A. in Information Science from the Free University of Berlin, Germany, and an M.B.A. in International Business from Anglia University, Cambridge.

  • Dr. Robert Capra:  Interfaces to Support Exploratory and Collaborative Search Tasks

Abstract:

Search interfaces are used by millions of users every day and provide access to a vast array of information stored in web pages, document collections, and other data sources.  The design of these interfaces mediates access to information and can influence our search processes.  Search interfaces have evolved over time, but providing high-precision ranked lists of results is a primary focus of many systems. Current search engines are effective in helping users complete simple search tasks such as fact-finding, but provide less support in helping users with tasks that may involve exploration, analysis, comparison, evaluation, and collaboration.

In this talk I will present results from a series of projects conducted with colleagues to develop and evaluate innovative search interfaces to support exploratory and collaborative search tasks. Across these projects, we observed how interface components influenced users’ search behaviors and ways that users made use of contextual information displayed by the interfaces at different stages of their search processes.  In my recent work, these observations helped inform the design of a novel search assistance tool that displays the search trails (paths) from previous users.  The idea behind the tool is that users may benefit from seeing how someone else approached the same or similar task.  Our implementation provides an interactive display with information about how another person searched, the queries they issued, results they clicked, and annotations made by the original searcher.  I will report on a laboratory study that investigated factors that influence user interaction with the search trails and effects on outcome measures.  Finally, I will conclude by discussing several exciting areas for future research on search interfaces.

  • Dr. Chirag Shah: Information Fostering: Proactively Supporting Information Seeking
  • Dr. Tuukka Ruotsalo: Interactive intent modeling

Abstract:

Information Fostering: Proactively Supporting Information Seeking

To assess information seeking/retrieval processes and outcomes, goodness of various objects involved in search such as queries and documents are evaluated. This evaluation could lead to recommendations (e.g., related queries, potentially useful books, interesting movies) to improve success and satisfaction of information seeker. However, in many cases, it may be too late to use those recommendations to mend the damage already done. Can we predict if a search session or project is moving on a suboptimal trajectory before it’s too late and offer suggestions to fix that trajectory - here referred to as Information Fostering? In this talk I will present some of our works that essentially provide a positive answer to this question. Specifically, I will talk about how we could analyze a search process in an exploratory search task to be able to predict its likelihood of success, and how we could switch the search trail of a possibly failing search with a one that could improve the chances of success dramatically. Extending this scenario to collaborative search, I will discuss our work that shows how we could do early detection of potential benefits of collaborating with someone for information seeking. I will also talk about the scenario when during a collaborative search, we could identify relative skills that individuals exhibit and use that knowledge to recommend roles that collaborators could assume in that search task. Finally, I will talk about some of our very recent works in which we are using data collected through mobile and wearable devices to predict one’s search behavior.

Abstract:

Interactive Intent modeling

User behavior analysis drive today’s internet applications; the pages we visit, the amount of time we view each page, the links we click on, and the queries we enter to search engines allow collecting data that can be used to improve web search, recommendation systems, or targeting online advertisement for users who exhibit a greater level of interest for the information that they search and consume. While user behavior has been successfully utilized for improving services, it is limited to the measurements that the current user interfaces allow us to record. In this talk, I will present some of our recent work on going beyond the behavioral measures to interactively model human intentions. I will discuss two approaches where human signals are used to predict search intentions and retrieve relevant information. First, I’ll discuss how explicit feedback from visualization is used in a reinforcement learning framework to learn user intentions in an information retrieval setting. Then, I will present how we can directly utilize human physiology and brain-activity to detect and mine informational intentions for retrieving digital information.

  • Pääkkönen, Teemu (Flocker): Exploring Behavioral Dimensions in Session Effectiveness
  • Saastamoinen, Mia (UTA): Queries in genuine work tasks: The effects of task type and complexity

Short bio / Casper Pedersen: Casper Petersen is a third-year Ph.D. student in Information Retrieval (IR) at the University of Copenhagen. He investigates the potential benefit of using statistical modelling and NLP to improve existing information retrieval tasks, such as (re-)ranking and posting list caching. His primary academic advisor is Christina Lioma, Associate Professor, Ph.D., University of Copenhagen.

Abstract / Casper Pedersen: This talk centers on two recent papers I co-authored:

1 - One property of well-written texts is coherence. Text coherence (TC) is the extent that a reader can understand the relations and ideas introduced in a text, and is central for comprehension. While a number of effective TC models exist, it is not well understood how they may be applied to existing IR tasks. In this paper, we develop two classes of TC models to assign coherence scores to documents. We show that both classes can achieve performance comparable to state-of-the-art for sentence re-ordering task (useful, for example, for automatic summarisation tasks), and significantly outperform strong baselines when re-ranking results based on a document's coherence score in ad hoc retrieval. This paper is presented at the ACM International Conference on the Theory of Information Retrieval (ICTIR) 2015 in Northampton, MA, USA.

2 - A posting list cache facilitates query processing, by storing--in a finite, but fast, local amount of memory--the posting lists (inverted lists) of the most popular query terms. A key challenge is how to select the query terms to cache. A recent greedy approach to static posting list caching substantially outperform other static and dynamic caching schemes, but a greedy approach does not formally guarantee an optimal solution. In this paper, we formulate the selection of what posting lists to cache as a constrained combinatorial optimisation (CCO) problem. Using simulated query logs, we show that using CCO gives small improvements in the number of cache hits over the greedy baseline for a number of cache sizes. This paper is presented at the Asian Information Retrieval Societies Conference (AIRS) 2015 in Brisbane, QL, Australia.

Short bio: Shuaiqiang Wang received Ph.D. and B.Sc. in Computer Science from Shandong University, China, in 2009 and 2004 respectively. During 2009, he was an exchange Ph.D. student at Hong Kong Baptist University. He is now a Tutkijatohtori (internationally equivalent to Assistant Professor) at Department of Computer Science and Information Systems, University of Jyväskylä in Finland. He was an Associate Professor at Shandong University of Finance and Economics from 2011 to 2014. He was a postdoctoral research associate at Texas State University in 2010. His research interests include recommender systems, information retrieval and data mining.

Abstract: Recently, ranking-oriented collaborative filtering (CF) algorithms have achieved great success in recommender systems. They obtained state-of-the-art performances by estimating a preference ranking of items for each user rather than estimating the absolute ratings on unrated items (as conventional rating-oriented CF algorithms do). In this paper, we propose a new ranking-oriented CF algorithm, called ListCF. Following the memory-based CF framework, ListCF directly predicts a total order of items for each user based on similar users' probability distributions over permutations of the items, and thus differs from previous ranking-oriented memory-based CF algorithms that focus on predicting the pairwise preferences between items. One important advantage of ListCF lies in its ability of reducing the computational complexity of the training and prediction procedures while achieving the same or better ranking performances as compared to previous ranking-oriented memory-based CF algorithms. Extensive experiments on three benchmark datasets against several state-of-the-art baselines demonstrate the effectiveness of our proposal.

  • Sanna Kumpulainen: "Task-based Information Access in Pharmacovigilance" Presentation of project proposal.

Maxwell's Abstract: Delays are a frustrating yet common occurrence in our lives. When using computers, we expect fast responses from systems such as search engines. However, what happens to users when search engines aren't as fast as expected? Studies have shown that even relatively small delays of 400 milliseconds incurred when returning search results can have an impact in user's search behaviours and information interactions. In this talk, I will present findings from a study which examined how query response delays and document download delays affect user interactions within a search system. Guided by existing theories in this area, we derived several hypotheses and put them to the test with 48 undergraduate subjects, split across four experimental conditions. We obtained interesting results, with a key finding being a strong and significant correlation between the time spent posing queries, and the interactions of subjects - in terms of the number of queries issued, the number of documents examined, and the depth to which the subjects went in the presented search results. These findings contrast with previous works on how delays affect search behaviours, and suggest that the underlying theories need to be refined to make more credible predictions relating to search behaviours.

The first talk is about humanities user needs more generally and about experimenting with facilitating user access to WWI content.

Lindquist's abstract: This talk will discuss the challenges encountered by and needs of humanities users in using digital 
historical primary sources. Further it will touch upon how a Linked Open Data (LOD) approach might help meet these user
needs by facilitating findability, accessibility, and context the sources. Historians, librarians, and computer scientists have
partnered in the World War I LOD Project to investigate how these goals might be achieved in a particular historical subdomain. 
The project will be discussed in more detail, including the datasets and vocabularies used and annotation method, illustrated
by a use case.
Lindquist's bio: Thea Lindquist is Associate Professor in the University Libraries at the University of Colorado Boulder (USA), 
where she has been and History and Germanic Studies Librarian since 2001. She is an historian by training. Her research interests
include the accessibility and usability of online primary sources, and particularly how a Linked Data approach might help meet
user needs in these areas. She also has interests in Digital Humanities and early modern European history.

  • Prof. Birger Larsen (Aalborg Univ, DK): "Investigating the use of anchor text to enhance retrieval in physics".
  • [room for presentations]

Christina's abstract: Inferring user information needs from queries is often hindered by the short query text and lack of user context. This talk presents two separate lines of work-in-progress aiming to improve our understanding of query semantics.

Part 1 presents a query reformulation method that mines candidate query reformulations from user-clicked documents and ranks them based on a commutation test on their terms. The user logs are provided by Karnov Group (a Danish provider of legal documentation) over a 10-month span. Experiments on ca. 1000 queries, simulating user relevance assessments, show the proposed method to be effective. In situ evaluation with expert Karnov users shows mixed results.

Part 2 presents an unsupervised method for estimating the non-compositionality of query terms. Non-compositional phrases have meanings that cannot be induced from the semantics of their composing terms, e.g. ‘hot dog’ or ‘red tape’. We extend the recent vector space approach of Kiela & Clark (2013) in detecting non-compositionality from contextual semantics, by proposing a probabilistic alternative, and apply it to find strong term dependence in 200 TREC Web track queries. Identifying strongly dependent query terms (and modelling their dependence during ranking) is shown to benefit retrieval effectiveness.

Christina's Bio: Christina Lioma is Associate Professor in the Department of Computer Science, University of Copenhagen. Her main research interests are in textual information retrieval and computational linguistics. Recent work is focused specifically on query/document representation (e.g. using graph theory or logic), linguistic evidence for ranking models (e.g. discourse, coherence), and domain-specific retrieval (e.g. rare medical diseases, scholarly data).

Birger's abstract: Anchor text, the text clicked on or immediately surrounding an outgoing hyperlink, has been used successfully to represent the document linked to in web search (e.g. Brin & Page, 1998). Ritchie and colleagues have shown the potential for exploiting anchor text in scientific and scholarly retrieval, but on fairly small and not publicly available datasets in the field of Computational Linguistics (Ritchie, Teufel and Robertson, 2009). As citation behaviour differs considerably between fields (Moed, 2005) we revisit the question of the usefulness of anchor text in a different field: physics. Using the iSearch test collection (Lykke et al., 2010) and full text versions of its documents now freely available from the electronic preprint archive arXiv.org, we investigate 1) if we can identify citations and anchor text reliably using iSearch and the latex arXiv source documents, 2) how to integrate this into ranking in a language modelling framework and 3) the optimal anchor text window size for this task. The presentation also presents iSearch and discusses the possibilities for building even larger scientific test collections for IR.

Birger's Bio: Birger Larsen is Professor in Information Analysis and Information Retrieval at the Department of Communication at Aalborg University Copenhagen. His main research interests include Information Retrieval (IR), structured documents in IR, XML IR and user interaction, domain specific search, understanding user intents and exploiting context in IR, as well as Informetrics/Bibliometrics, citation analysis and quantitative research evaluation.

Jaap's abstract: We have access to unprecedented amounts of information on the Web and in now digitized collections curated by museums, archives, libraries, publishers, or other institutions.  The large-scale availability of information about our past and present offers unprecedented opportunities for researchers and other users, but also presents many complexities when combining information from different collections, from different institutions, and from different traditions of documentation.  Big data collections bringing together many sources of information will be the driving force of research in the coming years.  Modern search methods are needed to exploit the availability of massive data of relevance to almost any conceivable research question, hence new search methods become new research methods and search and research evolve in parallel.

Jaap's bio:  Jaap Kamps is an associate professor of information retrieval at the University of Amsterdam's iSchool, PI of a stream of large research projects on information access funded by NWO and the EU, member of the ACM SIG-IR executive committee, organizer of evaluation efforts at TREC and CLEF, and a prolific organizer of conferences and workshops.  His research interests span all facets of information storage and retrieval -- from user-centric to system-centric, and from basic research to applied research. A common element is the combination of textual information with additional structure, such as document structure, Web-link structure, and/or contextual information, such as meta-data, anchors, tags, clicks, or profiles.   See: <http://staff.science.uva.nl/~kamps/>.

  • [room for presentations]

Barbara Wildemuth: Abstract
Interactive information retrieval (IR) experiments almost always assign search tasks for the study subjects to complete. These tasks may be of particular types (e.g., exploratory tasks or fact-finding tasks) or of varying levels of complexity or difficulty, or they may be a homogeneous set of search tasks. Over the past two years, a database of search tasks assigned in interactive IR studies has been compiled, including the full text of the tasks. A study of the exploratory tasks in the database revealed key attributes that help to clarify what we mean by this task type; a study of the known-item and fact-finding tasks in the database revealed the role they can continue to play in interactive IR studies; and a planned study of task complexity and difficulty will hopefully reveal a clearer definition of these two related by distinct concepts. Key findings from these studies will be presented.

Brief bio of Barbara Wildemuth
Barbara Wildemuth is Professor and Associate Dean in the School of Information and Library Science at the University of North Carolina at Chapel Hill.  Her research focuses on people’s use of information and information technologies. In particular, her research has included longitudinal studies of medical students’ searching of online databases, an evaluation of the effectiveness of a computerized presentation of a health maintenance/risk assessment questionnaire that adapts to the patient's literacy level and computer skills, and investigations of people's interactions with a collection of digital videos and their representations in the database. Her most recent work includes a needs assessment for use of personal health records, and a methodological study of the search tasks assigned in interactive information retrieval experiments. Her recent book, Applications of Social Research Methods to Questions in Information and Library Science, has been adopted as a text in a number of ILS schools in the United States and abroad. She has also been involved in developing curricula for digital library education and a project recruiting and educating medical informationists.  Her UNC teaching responsibilities include courses in various aspects of research methods (including theory development), human information interactions, and information ethics.

Pia Borlund: Abstract

Pia Borlund is the originator of the test instrument named a "simulated work task situation". This instrument is commonly used in interactive information retrieval (IIR) and seeking studies in form of written search tasks descriptions assigned to test participants. The objective of the use of simulated work task situations is to obtain realistic and reliable search behaviour during studying. What makes the design and tailoring of the simulated work task situations essential with respect to presenting a search task description that the test participants can relate to; in which they can identify themselves; and that they find topically interesting. However, past research shows how this requirement (and others) for the use of simulated work task situations are not always followed, which motivates the current research project on "Meta-evaluations of simulated work task situations". The purpose of the research project is to refine and improve the requirements for the use of simulating work task situations, and hereby to increase the research standard of empirical IIR and seeking studies. The test instrument of a simulated work task situation is studied via a series of empirical studies, these are:

  • A replica study of the original work by Borlund (uni students from Aalborg University)
  • A study focusing on the effect of tailoring (uni students from the RSLIS)
  • A study of the order effect of simulated work task situations (uni students from the RSLIS)
  • A study of school children and school teachers' use of simulated work task situations children (under planning)
  • (An ELIS study that investigates Ingwersen's three types of information needs)

Brief bio of Pia Borlund

Pia Borlund is Professor at the Royal School of Library and Information Science (RSLIS), Copenhagen University, and Docent at the School of Information Sciences, Tampere University. Her research focuses on the design and evaluation of systems that support users' interactive information retrieval (IIR). She is interested in the confluence of information retrieval (IR), human-computer interaction, and information seeking behaviour from a task based perspective. She has conducted research on frameworks and guidelines for performance evaluation of IIR systems centred on the concept of simulated work task situation by involvement of users. Her current research focuses on methodological issues, experimental design and requirements for user-based performance evaluation. In addition, she is interested in the concept of relevance, including users' relevance assessment behaviours of different work and search tasks, as well as the nature of subjective, non-binary relevance.

Usually parameters of these metrics are chosen on the basis of general considerations and not validated by experiments with real users. Particularly, the parameters of the Expected Reciprocal Rank measure are the normalized parameters of the DCG metric, and the latter are chosen in an ad-hoc manner. We suggest two approaches for adjusting parameters of the ERR model by analyzing real users behaviour: one based on a controlled experiment and another relying on search log analysis. We show that our approaches generate parameters that are largely different from the commonly used parameters of the ERR model.

Abstract: The talk will discuss what the role of an evaluation infrastructure can be for supporting large-scale evaluation campaigns, what are the challenges it has to face, what can be its impact on experimental evaluation. It will then discuss ongoing and future perspectives such as the exploitation of visual analytics for understanding experimental results and how to support simulation as a bridge between laboratory style evaluation and user-centered evaluation.

  • Dr Veslava Osinska (Nicolaus Copernicus U, Poland)): "Classification Map as an Information Retrieval Interface".       Abstract: We have mapped the document collection of Association for Computing Machinery (ACM) digital library to a sphere surface. To overcome the incorrectness of linear measures in indexes distances we calculated similarity matrix of themes and multidimensional scaling coordinates. The results show that space distances between class nodes accurately correspond with the thematic proximities. Documents mapped into a sphere surface were distributed around the classification nodes in proper locations. The proposed method of classification scheme visualization is suitable to reach nonlinearity in topic mapping of scholar resources. This property allows to accumulate much more classification nodes. The symmetry of a sphere favours a new subclasses and sublevels of classification trees uniform visualization. This method may be useful for the visual analysis of Computer Science and Engineering development being grown instantly. Visualization tools more recently exploited to retrieve information. Output visualization maps were tested as information retrieval (IR) interface. Input parameters controlled by IR results were tested and this way the most effective were selected. Possible feedback between visualization/retrieval system and user search need is the main advantage of the application.
