Tidskriftsartikel (refereegranskat)abstract
- During a three-day workshop in February 2012, 45 Information Retrieval researchers met to discuss long-range challenges and opportunities within the field. The result of the workshop is a diverse set of research directions, project ideas, and challenge areas. This report describes the workshop format, provides summaries of broad themes that emerged, includes brief descriptions of all the ideas, and provides detailed discussion of six proposals that were voted "most interesting" by the participants. Key themes include the need to: move beyond ranked lists of documents to support richer dialog and presentation, represent the context of search and searchers, provide richer support for information seeking, enable retrieval of a wide range of structured and unstructured content, and develop new evaluation methodologies.

Konferensbidrag (refereegranskat)abstract
- There is an increasing amount of structure on the Web as a result of modern Web languages, user tagging and annotation, emerging robust NLP tools, and an ever growing volume of linked data. These meaningful, semantic, annotations hold the promise to significantly enhance information access, by enhancing the depth of analysis of today’s systems. The goal of the ESAIR’14 workshop remains to advance the general research agenda on this core problem, with an explicit focus on one of the most challenging aspects to address in the coming years. The main remaining challenge is on the user’s side-the potential of rich document annotations can only be realized if matched by more articulate queries exploiting these powerful retrieval cues-and a more dynamic approach is emerging by exploiting new forms of query autosuggest. How can the query suggestion paradigm be used to encourage searcher to articulate longer queries, with concepts and relations linking their statement of request to existing semantic models? How do entity results and social network data in "graph search" change the classic division between searchers and information and lead to extreme personalization-are you the query? How to leverage transaction logs and recommendation, and how adaptive should we make the system? What are the privacy ramifications and the UX aspects-how to not creep out users?

Fourth workshop on Exploiting Semantic Annotations in Information Retrieval (ESAIR)
- 2011. - 11
-
Konferensbidrag (refereegranskat)abstract
- There is an increasing amount of structure on the Web as a result of modern Web languages, user tagging and annotation, and emerg- ing robust NLP tools. These meaningful, semantic, annotations hold the promise to significantly enhance information access, by enhancing the depth of analysis of today’s systems. Currently, we have only started exploring the possibilities and only begin to un- derstand how these valuable semantic cues can be put to fruitful use. Unleashing the potential of semantic annotations requires us to think outside the box, by combining the insights of natural lan- guage processing (NLP) to go beyond bags of words, the insights of databases (DB) to use structure efficiently even when aggregating over millions of records, the insights of information retrieval (IR) in effective goal-directed search and evaluation, and the insights of knowledge management (KM) to get grips on the greater whole. This workshop aims to bring together researchers from these dif- ferent disciplines and work together on one of the greatest chal- lenges in the years to come. The desired result of the workshop will be to gain concrete insight into the potential of semantic an- notations, and in concrete steps to take this research forward; to synchronize related research happening in NLP, DB, IR, and KM, in ways that combine the strengths of each discipline; and to have a lively, interactive workshop where every participant contributes actively and which inspires attendees to think freely and creatively, working towards a common goal.

- There is an increasing amount of structure on the Web as a result of modern Web languages, user tagging and annotation, and emerging robust NLP tools. These meaningful, semantic, annotations hold the promise to significantly enhance information access, by increasing the depth of analysis of today’s systems. Currently, we have only started to explore the possibilities and only begun to understand how these valuable semantic cues can be put to fruitful use. The workshop had an interactive format consisting of keynotes, boasters and posters, breakout groups and reports, and a final discussion, which was prolonged into the evening. There was a strong feeling that we made substantial progress. Specifically, each of the breakout groups contributed to our understanding of the way forward. First, annotations and use cases come in many different shapes and forms depending on the domain at hand, but at a higher level there are remarkable commonalities in annotation tools, indexing methods, user interfaces, and general methodology. Second, we got insights in the "exploitation" aspects, leading to a clear separation between the low-level annotations giving context or meaning to small units of information (e.g., NLP, sentiments, entities), and annotations bringing out the structure inherent in the data (e.g., sources, data schemas, document genres). Third, the plan to enrich ClueWeb with various document level (e.g., pagerank and spam scores, but also reading level) and lower level (e.g., named entities or sentiments) annotations was embraced by the workshop as a concrete next step to promote research in semantic annotations.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Reglerna som möjliggör stängning av hemsidor på internet präglas av godtycke och otydlighet. Men det behöver inte vara särskilt svårt att skapa ett nytt och rättssäkert regelverk. Här har Sveriges EU-kommissionär Cecilia Malmström en viktig roll. Frågan är om hon tar sitt ansvar, skriver politiker och nätdebattörer.

Resource Lenient Approaches to Cross Language Information Retrieval : Using Amharic
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Information Retrieval (IR) deals with finding and presenting information from a collection of documents/data that are relevant to an information need (a query) expressed by a user. Cross Language Information Retrieval (CLIR) is a subfield of IR where queries are posed in a different language than that of the document collection. Computational linguistic tools and resources are essential to accomplish the tasks in CLIR and to date, CLIR research is dominated by a very limited number of languages for which such tools and resources are available. In order to facilitate global information sharing, it is important to enable access to information using as many languages as possible. This requires an investigation into the feasibility of CLIR for languages with a limited set of computational linguistic resources. Amharic is a well-studied language with a rich history and culture, but has very limited computational linguistic tools and resources. This dissertation provides an in depth investigation into a CLIR system for Amharic (against English and French document collections). Scalable techniques were developed to accomplish Amharic CLIR tasks and each task was evaluated individually as a stand alone experiment. Large scale IR experiments were then conducted in order to evaluate the effect of three parameters, namely, transliteration, word sense discrimination, and term selection based on part of speech tags, on the overall IR performance. The effects were measured by individually tuning each of these parameters through a series of benchmarking experiments, geared towards optimizing retrieval precision as well as recall. The results give an insight into the performance of the chosen approaches, the challenges, and their impact on the overall IR performance.

Report on the SIGIR workshop on "entertain me" : supporting complex search tasks
- 2011
-
Ingår i: SIGIR Forum. - : Association for Computing Machinery. - 0163-5840 .- 1558-0229. ; 45
-
Tidskriftsartikel (refereegranskat)abstract
- Searchers with a complex information need typically slice-and-dice their problem into several queries and subqueries, and laboriously combine the answers post hoc to solve their tasks. Consider planning a social event at the last day of SIGIR, in the unknown city of Beijing, factoring in distances, timing, and preferences on budget, cuisine, and entertainment. A system supporting the entire search episode should "know" a lot, either from profiles or implicit information, or from explicit information in the query or from feedback. This may lead to the (interactive) construction of a complexly structured query, but sometimes the most obvious query for a complex need is dead simple: entertain me. Rather than returning ten-blue-lines in response to a 2.4-word query, the desired system should support searchers during their whole task or search episode, by iteratively constructing a complex query or search strategy, by exploring the result-space at every stage, and by combining the partial answers into a coherent whole.The workshop brought together a varied group of researchers covering both user and system centered approaches, who worked together on the problem and potential solutions. There was a strong feeling that we made substantial progress. First, there was general optimism on the wealth of contextual information that can be derived from context or natural interactions without the need for obstrusive explicit feedback. Second, the task of "contextual suggestions"--matching specific types of results against rich profiles--was identified as a manageable first step, and concrete plans for such as track were discussed in the aftermath of the workshop. Third, the identified dimensions of variation--such as the level of engagement, or user versus system initiative--give clear suggestions of the types of input a searcher is willing or able to give and the type of response expected from a system.
